DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In addition, in the embodiments of the present application, "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0019] In the improvement of saline-alkali land, it is currently believed that one of the best options is the combination of microbial agent placement + crop cultivation. Crop cultivation can even achieve better results. At the same time, it is found that the better the crop growth, the better the improvement effect on saline-alkali land. However, in crop cultivation and growth, trace elements will have a fundamental impact on the growth of crops. Therefore, in the specific cultivation process, the formula of trace element fertilizers needs to be adjusted accordingly. However, the effect of trace element fertilizers will be affected by multiple factors at the same time. At present, this influencing factor has not been generally analyzed, but fertilization operations are directly based on experience, resulting in unreasonable formulas of trace element fertilizers, and poor promotion effects on saline-alkali land improvement. At the same time, the formula of trace element fertilizers has not been adjusted in real time, and the relationship between the consumption of trace element fertilizers and saline-alkali substances has not been established. As a result, in the process of applying trace element fertilizers, only qualitative analysis of saline-alkali land improvement can be carried out, and it is difficult to conduct quantitative analysis of the amount of trace element fertilizers applied.

[0020] In order to solve the problems existing in the prior art, the present application discloses a method for adjusting the formula of trace element fertilizer based on the requirements for improving saline-alkali land, such as Figure 1 As shown, it is a flow chart of a method for adjusting the formula of trace element fertilizer based on the requirements for improving saline-alkali land provided in an embodiment of the present application, specifically: S110. Obtaining the saline-alkali substance composition in different areas of the saline-alkali land, and obtaining the regional saline-alkali substance content of the saline-alkali land.

[0021] S120. Obtain a periodic trace element fertilizer formula based on the regional saline-alkali substance content.

[0022] S130, obtaining the regional saline-alkali substance content after applying the trace element fertilizer of the periodic trace element fertilizer formula, and obtaining a saline-alkali substance consumption equation.

[0023] S140, obtaining the saline-alkali land improvement cycle target and the saline-alkali material consumption equation to obtain the trace element fertilizer formula for the next improvement cycle.

[0024] S150, obtaining environmental change parameters of the saline-alkali land, and based on the environmental change parameters, obtaining the saline-alkali substance content of the saline-alkali land, and obtaining the sudden change saline-alkali substance content.

[0025] S160. Based on the mutant saline-alkali substance content and the saline-alkali land improvement cycle target, obtain a trace element fertilizer formula under environmental influences.

[0026] The purpose of all the above steps is to realize the real-time and quantitative formula adjustment of the trace element fertilizers needed for saline-alkali land improvement. At the same time, the influence of trace element fertilizers on saline-alkali land improvement caused by changes in external environmental parameters is also considered, so as to further improve the role of trace element fertilizers in the process of saline-alkali land improvement.

[0027] Below, all the above steps will be described in detail, specifically: As described in step S110, the purpose of this step is to obtain the baseline value of saline-alkali substances in the saline-alkali land area. At the same time, considering that the saline-alkali land area usually covers a large area, and the content of saline-alkali substances in different areas is often very different due to different environments and sowing conditions, the saline-alkali land is divided into regions, so that different formulas of trace element fertilizers are placed in different saline-alkali land areas to improve the improvement effect of saline-alkali land in different regions. Specifically: S111. Evenly lay saline-alkali substance detection devices on the saline-alkali land to detect the saline-alkali substance composition of the saline-alkali land in real time.

[0028] The purpose of this step is that when improving saline-alkali land, it is necessary to know the content of saline-alkali substances in the saline-alkali land when adjusting the formula of trace element fertilizer based on the requirements of saline-alkali land improvement. At the same time, considering that different regions may have different contents, it is difficult to know the specific content of saline-alkali substances before the improvement work is implemented. Therefore, it is necessary to evenly lay out detection devices to obtain the composition of saline-alkali substances, which will then facilitate the implementation of regional division work.

[0029] Among them, saline-alkali substance detection devices are evenly laid out throughout the entire saline-alkali land, and such devices can be evenly arranged based on the spacing between each other.

[0030] Among them, the saline-alkali substance detection device has a component detection function and a concentration measurement function in the soil, so that the component and concentration of the saline-alkali substance can be directly determined, that is, the content of the saline-alkali substance can be obtained.

[0031] Among them, the saline-alkali substance detection device is based on the communication system, which obtains and sends the detection results of saline-alkali substances to the control center in real time, so as to determine the composition and content of the substances and use them for subsequent trace element fertilizer formula adjustments.

[0032] S112, defining the areas where the deviation of the saline-alkali material composition is not higher than the preset deviation as the same partition area.

[0033] The purpose of this step is to divide all plots in the saline-alkali land according to the type and content of saline-alkali substances, so as to divide similar areas in the saline-alkali land into regions, so that different trace element fertilizer formulas can be used for different regions.

[0034] Wherein, based on the saline-alkali substance detection device that is set up, the type and content of the saline-alkali substance at the location where the device is set up are directly collected.

[0035] Here, each parameter of the saline-alkali material component collected is obtained, and compared with the saline-alkali material components collected by the surrounding devices to obtain the deviation.

[0036] The obtained deviation is compared with a preset deviation, which is set by a technician.

[0037] In some embodiments, the average of all deviations is obtained, and then the average is directly used as the preset deviation.

[0038] In some embodiments, regions can also be demarcated according to the main plant types in saline-alkali land in different regions. Taking into account that different types of plants have different salt-alkali tolerance, the saline-alkali substance composition of the region is determined based on the plants with the highest proportion as the main observation objects and the salt-alkali tolerance of the plants.

[0039] Among them, in the area where the deviation is not higher than the preset deviation, based on the measurement results of the salt-alkali substance detection device, all the salt-alkali substance detection devices that meet the judgment index are included in the same area, that is, the same partition area is obtained.

[0040] S113, obtaining the mean value of the saline-alkali substance composition in the same partition area to obtain the saline-alkali substance content in the same partition area.

[0041] The purpose of this step is to estimate the composition or content of saline-alkali substances in all the same partitioned areas, wherein the calculation based on the mean has higher accuracy and lower computing resource consumption.

[0042] Here, the readings of all saline-alkali substance detection devices in the same partition area are obtained and their average is calculated.

[0043] Among them, considering that there may be many different types of saline-alkali substances in saline-alkali land, it is necessary to analyze all types of saline-alkali substances therein separately, and calculate the mean content of all types of saline-alkali substances therein separately.

[0044] S114. Mark the saline-alkali substance content of all the same sub-areas to obtain the regional saline-alkali substance content of the saline-alkali land.

[0045] The purpose of this step is that in the technical solution of the present application, the adjustment of trace element fertilizer needs to be implemented based on the control system. Therefore, marking the regional saline-alkali content of saline-alkali land can facilitate the subsequent specific control of trace element fertilizer.

[0046] In the control system, a unique label is set for all the same partition areas, so as to mark all the same partition areas.

[0047] Among them, on the basis of all the same sub-areas, the regional saline-alkali substance content in the same sub-area is marked to illustrate the saline-alkali substance composition in the sub-area.

[0048] S115, further comprising: Trace element fertilizer dispensers are evenly set up in the same partition area to apply trace element fertilizers for saline-alkali land improvement.

[0049] The purpose of this step is to use a special dispenser for trace element fertilizer in the improvement of saline-alkali land, so that the fertilizer can be dispensed using the dispenser, and the operation status of the trace element fertilizer dispenser can be screened according to the zoning distribution of the saline-alkali land to achieve reasonable placement.

[0050] Among them, in the same partition area, a trace element fertilizer dispenser is evenly distributed, and fertilizer is placed based on the dispenser.

[0051] In some embodiments, the trace element fertilizer dispensers have been arranged. Then, based on the division result of the same partition area, the trace element fertilizer dispensers in the same partition area are regarded as the trace element fertilizer dispensers inherent in the area.

[0052] In some embodiments, the layout position of the trace element fertilizer dispenser can be configured based on the detection results obtained by the saline-alkali substance detection device in the same partition area. For example, if a detection device finds that the saline-alkali substance content at the location where it is located is significantly higher than the measurement results of other detection devices, and it belongs to the same partition area, then it is necessary to configure the trace element fertilizer dispenser at the location where the detection device is located, while the layout density of the trace element fertilizer dispenser in other areas is reduced, or even not arranged. In this way, the trace element fertilizer dispensers in the same partition area are not evenly arranged.

[0053] As described in step S120, the purpose of this step is to improve saline-alkali land. The principle of this application is that the elimination stage of saline-alkali substances is based on the consumption of the crops planted. For different types of crops, the consumption and demand for trace elements are different. Therefore, the formula of trace element fertilizer is obtained in advance based on the type of crops planted, and then the formula is adjusted. The obtained formula that needs to be adjusted is obtained to obtain the formula of trace element fertilizer. At the same time, different transformation times will be divided in the transformation of saline-alkali land. Therefore, in the specific processing, the formula can be obtained for the current cycle. Specifically: S121. Based on the regional saline-alkali substance content, obtain the regional saline-alkali substance category.

[0054] The purpose of this step is to obtain the type of crops suitable for planting based on the type and content of saline-alkali substances in the region.

[0055] Among them, the regional saline-alkali substance content is obtained to directly determine the type of saline-alkali substance in the current area.

[0056] Among them, the suitable crops for planting in the area are determined based on the type and content of saline-alkali substances.

[0057] S122. Obtain the saline-alkali substance content corresponding to the regional saline-alkali substance category, and obtain the proportion of the saline-alkali substance content to obtain the saline-alkali substance ratio.

[0058] The purpose of this step is that different crops have different adaptability to different saline-alkali substances. Therefore, in the specific treatment, it is also necessary to obtain the ratio of saline-alkali substances. After determining the ratio result, further screening is performed for suitable crops.

[0059] The composition of all saline-alkali substances in the partition is obtained, and based on the composition, the distribution of the saline-alkali substances therein is directly determined.

[0060] Among them, the proportion of saline-alkali substances can be described based on weight ratio, concentration ratio, etc., and this application does not limit it.

[0061] Among them, all the proportions of saline-alkali substances are marked separately, so as to obtain the correlation between the proportions of saline-alkali substances and the same partition area.

[0062] S123. Based on the regional saline-alkali material ratio and the regional saline-alkali material category, obtain suitable crops for planting.

[0063] The purpose of this step is to screen suitable crops for planting according to the obtained saline-alkali substance content and saline-alkali substance ratio, so as to ensure that the crops in the area can consume the saline-alkali substances.

[0064] Among them, suitable crops are screened according to the categories of saline-alkali substances and based on the nutrient requirements of crops during their growth.

[0065] Among them, the crops to be planted can be screened according to the subsequent treatment measures for the crops planted in the improvement of saline-alkali land, combined with the types of saline-alkali substances. For example: the improvement operation of a saline-alkali land area is determined, and it is also necessary to turn the crops into the soil after the corresponding crops are planted to increase the organic matter content of the soil, and the acidity of the soil is relatively high, then the crop to be planted is alfalfa.

[0066] Among them, suitable crops can also be selected according to the dominant saline-alkali substances in the saline-alkali land. For example, if the salt content is the highest in a certain area, the optional crops include Suaeda salsa, Salicornia herba, etc., to consume the salt in the saline-alkali land.

[0067] Among them, the crops to be planted can also be selected according to other saline-alkali land improvement methods used at the same time. For example, if the saline-alkali land is improved by adding microbial agents, Elaeagnus angustifolia can be planted to increase the microbial activity in the soil.

[0068] S124. Based on the suitable crops to be planted, a formula of periodic trace element fertilizer is obtained.

[0069] The purpose of this step is to determine the formula of trace element fertilizer and construct the formula based on its demand for trace element fertilizer. Specifically: S1241, obtaining the consumption rate of the saline-alkali substances by the suitable crops in the same sub-area, and obtaining the improvement rate of the trace element fertilizer formula. Figure 2 As shown, it is a schematic diagram of a trace element fertilizer dispenser in a trace element fertilizer formula adjustment method based on saline-alkali land improvement requirements provided in an embodiment of the present application. Each numbered area is a storage area for a single trace element fertilizer, the elliptical opening therein is a fertilizer delivery hole, and the horizontal direction in the opening is the upper edge line of the opening baffle. By setting different opening baffle positions, a corresponding amount of trace element fertilizer can be delivered.

[0070] The purpose of this step is to consider that the content and composition of saline-alkali substances in different areas on saline-alkali land may be different. In order to obtain better improvement effects, after determining the initial formula of trace element fertilizer, it is obviously necessary to further adjust the initial formula. Then, it is necessary to analyze the consumption rate of saline-alkali substances by crops planted in different partitioned areas to obtain a benchmark saline-alkali substance consumption rate.

[0071] Among them, on the basis of determining the suitable crops to be planted, a trace element fertilizer formula is established based on the needs of different growth cycles of crops.

[0072] In some embodiments, for the set trace element fertilizer formula template, the template is compared with the determined suitable planting crops. When it is found that there is no comparison result, it needs to be rebuilt. If a good adaptation effect is found, it is directly selected.

[0073] In some embodiments, the total amount of trace element fertilizer to be applied is determined based on the demand for trace element fertilizers of the crops throughout their life cycle and the planting area, as well as the adverse effects of excessive trace element fertilizers on the crops, and the total amount of application is determined as a formula.

[0074] After the crops are planted, the content of saline-alkali substances in the saline-alkali land is continuously and real-time measured based on the saline-alkali substance detection device.

[0075] Among them, by obtaining the content change value of saline-alkali substances within a period of time and the ratio of the content change value to the time length, the improvement speed of the trace element fertilizer formula can be obtained.

[0076] In some embodiments, very short time periods are uniformly set to determine the consumption of saline-alkali substances by the crops in different growth cycles, thereby obtaining the consumption rate of saline-alkali substances by the crops in different growth cycles.

[0077] S1242. Obtain the growth-promoting effects of different trace element fertilizers on the suitable crops in the trace element fertilizer formula with the highest trace element fertilizer improvement rate, and obtain the single element improvement rate.

[0078] The purpose of this step is to analyze the growth-promoting effects of different types of trace element fertilizers on planted crops, to obtain the promoting effects of various elements in them on the improvement rate of saline-alkali land, and to adjust the formula of trace element fertilizers based on the determination of a single improvement rate.

[0079] Among them, the demand for trace element fertilizers in different time periods can be determined based on the suitable crops being planted.

[0080] In some embodiments, the formula of the trace element fertilizer is continuously adjusted to determine the growth promoting effect on the planted crops, thereby analyzing the improvement rate of a single element in the trace element fertilizer.

[0081] In some embodiments, based on slight adjustments to the trace element fertilizer formula, the growth-promoting effects of different formulas on planted crops are obtained, thereby obtaining adjusted formulas, and the formula with the best growth-promoting effect on planted crops is selected for application.

[0082] In some embodiments, based on simulated cultivation technology (i.e., cultivation in plots with similar environments and similar saline-alkali content), trace element fertilizers with different ratios are added, and the growth effects of planted crops are obtained, so as to determine the growth-promoting effect of any trace element in different trace element fertilizer formulas on planted crops, that is, to obtain the single element improvement rate.

[0083] S1243. Based on the single element improvement rate, adjust the trace element fertilizer formula to obtain a periodic trace element fertilizer formula.

[0084] The purpose of this step is to adjust the formula after obtaining the improvement rate of a single element, and at the same time, based on the content of saline-alkali substances, obtain the number of crops planted therein and make final adjustments to the formula.

[0085] Among them, the content of saline-alkali substances is obtained, the number of crops planted in the area is obtained, and the amount of saline-alkali substances that can be consumed during the entire life cycle of the crops.

[0086] Among them, the improvement rate of a single element is targeted to obtain the trace element with the best growth-promoting effect on the planted crops, and the input ratio of the element is increased to achieve the adjustment of the trace element fertilizer formula.

[0087] Among them, the formula of periodic trace element fertilizer is adjusted based on the growth cycle of the crops planted, and then the obtained formula is released into the saline-alkali land area.

[0088] Among them, the total amount of saline-alkali substances that can be consumed by the planted crops during their entire life cycle is obtained after the trace element fertilizer is added according to the periodic trace element fertilizer formula.

[0089] In some embodiments, the difference between the total amount of saline-alkali substances that the cultivated crops can consume during their entire life cycle and the saline-alkali land improvement target specified during the period is calculated. The difference is the deviation amount by which the trace element fertilizer formula fails to achieve the target. Based on the deviation amount, the trace element fertilizer formula is further adjusted.

[0090] As described in step S130, the purpose of this step is to use the consumption of trace element fertilizer and saline-alkali substances for suitable crops as intermediate quantities, obtain the consumption of saline-alkali substances caused by the input of trace element fertilizer in the case of the crops, establish a saline-alkali substance consumption equation for these two parameters, and establish a correlation between the consumption of trace element fertilizer and saline-alkali substances. Specifically: S131. Based on the periodic trace element fertilizer formula, the trace element fertilizer dispenser dispenses the trace element fertilizer into the trace element fertilizer delivery coverage area.

[0091] The purpose of this step is that after the periodic trace element fertilizer formula has been determined, since the formula is based on theoretical calculations, in order to further adjust the formula, it is necessary to add fertilizer based on the periodic trace element fertilizer formula and obtain the dependent variable (salt-alkali substance consumption) and independent variable (trace element fertilizer), laying the foundation for the subsequent determination of the salt-alkali substance consumption equation.

[0092] Among them, after obtaining the formula of periodic trace element fertilizer, it can be dispensed by the trace element fertilizer dispenser.

[0093] Among them, the trace element fertilizer dispensers contained in the same designated partition area have the same method of delivering trace elements. In this process, it is necessary to uniformly control and configure the trace element fertilizer dispensers in the partition area based on the same designated partition area.

[0094] Among them, based on the label of the trace element fertilizer dispenser, the control system sends the same control instruction to the trace element fertilizer dispensers in the same partition area, so that different trace element fertilizer dispensers in the same partition area can apply the same formula of trace element fertilizer to the saline-alkali land.

[0095] In some embodiments, each trace element fertilizer dispenser is independently controlled so that different trace element fertilizer dispensers can dispense trace element fertilizers of different formulations based on control instructions.

[0096] Among them, after obtaining the formula of the trace element fertilizer that the trace element fertilizer dispenser needs to dispense, corresponding adjustments are made and the trace element fertilizer is dispensed.

[0097] S132, setting the detection time of the trace element fertilizer delivery coverage area, and obtaining the saline-alkali substance content in the trace element fertilizer delivery coverage area to obtain the measured substance content.

[0098] The purpose of this step is that after the trace element fertilizer is put in, it will promote the growth of the crops, and the crops consume saline-alkali substances during their growth. Therefore, in order to obtain the saline-alkali substance consumption equation, it is obviously necessary to obtain the saline-alkali substance consumption. This step is to obtain the saline-alkali substance consumption.

[0099] Among them, after the trace element fertilizer is put in, the content of saline-alkali substances in the saline-alkali land area is obtained, and the content of saline-alkali substances needs to be monitored in real time.

[0100] After the content of saline-alkali substances is obtained, the change in the content of saline-alkali substances in adjacent time periods is obtained, thereby obtaining the consumption of saline-alkali substances in different time periods.

[0101] In some embodiments, the content of saline-alkali substances between the trace element fertilizer delivery time node and other time nodes is obtained to obtain the consumption of saline-alkali substances at different time nodes.

[0102] In some embodiments, the value may be determined based only on the content of saline-alkali substances in the delivery area.

[0103] S133. Based on the measured substance content, obtain a consumption curve of saline-alkali substances in the area covered by the trace element fertilizer.

[0104] The purpose of this step is to determine the consumption of saline-alkali substances in the saline-alkali area after obtaining the measured material content, and obtain the corresponding consumption curve based on the consumption, and then determine the saline-alkali substance consumption equation based on the consumption curve.

[0105] Among them, for the obtained amount of saline-alkali substances, detection time nodes for the saline-alkali substance content in the saline-alkali land are established to obtain the saline-alkali substance content corresponding to different time nodes.

[0106] Among them, the saline-alkali substance content measured at adjacent time nodes is obtained, and the difference between adjacent time nodes is calculated, so as to obtain the saline-alkali substance consumption in the coverage area after the trace element fertilizer is released.

[0107] Among them, based on the parameters of the time node and the consumption of saline-alkali substances, the obtained saline-alkali substance consumption value is incorporated into the spatial coordinate system to obtain the saline-alkali substance consumption curve. Figure 3 As shown, it is a consumption curve of saline-alkali substances in a method for adjusting the formula of trace element fertilizers based on the requirements for improving saline-alkali land provided in an embodiment of the present application. The curve is a curve of the consumption of saline-alkali substances over a period of time after the molybdenum fertilizer is added during the alfalfa seedling stage. After obtaining the curve, the consumption equation of saline-alkali substances can be obtained. It should be noted that Figure 3 It is just a theoretical cover-up for a saline-alkali material consumption curve, that is, it is more common for saline-alkali material consumption to develop in the form of an exponential function, but not all trace element fertilizers develop in the form of an exponential function, and in the measured values, the fit is usually not as good as Figure 3 The performance is good, but in any case, the corresponding equation can be determined based on the obtained consumption curve.

[0108] Among them, after obtaining the consumption curve, the consumption change equation of saline-alkali substances in the area covered by trace element fertilizer delivery is obtained based on the consumption curve, laying the foundation for subsequent steps.

[0109] In some embodiments, a corresponding saline-alkali substance consumption curve may also be established based on other parameters, such as the time node of the introduction of trace element fertilizers, which is not limited in this application.

[0110] S134. Based on the consumption curve of saline-alkali substances in the area covered by the trace element fertilizer, obtain the consumption equation of saline-alkali substances under the periodic trace element fertilizer formula.

[0111] The purpose of this step is to determine the consumption of saline-alkali substances under the periodic trace element fertilizer formula based on the obtained saline-alkali substance consumption curve, and obtain the correlation equation between the two, so as to obtain the saline-alkali substance consumption equation. In the subsequent processing, the amount of trace element fertilizer to be added can be determined based on the saline-alkali substance consumption equation and the target consumption.

[0112] Among them, the trace element fertilizer consumption of the planted crops in the corresponding time period is obtained.

[0113] In some embodiments, the consumption of trace element fertilizer is determined based on the specific consumption rate of the planted crops in different growth cycles, such as dividing the crops into germination period, growth period, fruiting period and withering period.

[0114] Among them, the consumption of trace element fertilizers by planted crops at adjacent time nodes is obtained, and the equation is obtained.

[0115] In some embodiments, a consumption equation is also established for the consumption of trace element fertilizer to determine the consumption rate and total amount of trace element fertilizer in different cycles.

[0116] Among them, the ratio of the trace element fertilizer consumption and the saline-alkali substance consumption in the corresponding time period is obtained, and the total amount of trace element fertilizer required to be invested in different time periods to achieve the saline-alkali substance consumption target is obtained, and the quotient of the target amount and the ratio is obtained.

[0117] In some embodiments, other methods may also be used to obtain the amount of trace element fertilizer to be added under the target consumption of saline-alkali substances.

[0118] Among them, the promoting effect of different elements in trace element fertilizer on crop growth is obtained and quantitatively processed, and the obtained promoting effect value is the input weight of different trace elements in the trace element fertilizer.

[0119] Among them, based on the obtained input weight and the trace element composition under the target consumption of saline-alkali substances, the corresponding saline-alkali substance consumption equation can be established. For example, for a certain saline-alkali land area, the saline-alkali substance consumption equation established is: ; in, C Indicates the consumption of saline and alkali substances. Indicates the weight of the effect of a single trace element fertilizer on the consumption of saline-alkali substances. The equation for the consumption of saline and alkali substances is: i Indicates the type index of single trace element fertilizer, j Indicates the total amount of single trace element fertilizer type index.

[0120] Among them, the saline-alkali substance consumption equation corresponding to different single trace element fertilizers can be tested without adding other types of trace element fertilizers, but only adding the trace element fertilizer that needs to be analyzed.

[0121] Among them, the weight corresponding to the above equation can be based on the amount of different trace element fertilizers required to be put in when consuming the same content of saline-alkali substances, and the obtained ratio of the amount put in is the weight value.

[0122] S135. Obtain the content of saline-alkali substances at the start time point and the end time point during the saline-alkali land improvement cycle, and obtain the target consumption of saline-alkali substances.

[0123] The purpose of this step is to set the improvement requirements of saline-alkali land in different time periods based on the time period in the improvement of saline-alkali land. It is usually set based on the content of saline-alkali substances contained in the saline-alkali land and implemented in the form of indicators. In order to ensure the effectiveness of saline-alkali land improvement, it is necessary to identify the requirements and determine the problems in the improvement of saline-alkali land in the current cycle.

[0124] Among them, based on the effective time node and the termination time node of the improvement target set for the improvement of saline-alkali land, and obtaining the required saline-alkali substance content at the corresponding time node, the target consumption of saline-alkali substances is obtained.

[0125] S136. Divide the trace element fertilizer adjustment time period within the saline-alkali land improvement cycle, and obtain the saline-alkali substance consumption within each trace element fertilizer adjustment time period to obtain the target time period consumption.

[0126] The purpose of this step is to measure the consumption of saline-alkali substances within the time period when the saline-alkali substance consumption equation has been obtained. At the same time, considering that the adjustment time period of trace element fertilizers and the saline-alkali substance consumption time period may not match, it is also necessary to determine the adjustment time period of trace element fertilizers and determine the consumption of saline-alkali substances during the entire saline-alkali land improvement cycle.

[0127] Among them, the adjustment time period for trace element fertilizer is determined based on the growth cycle of the planted crops.

[0128] Among them, the time nodes of the growth cycle of planted crops and the saline-alkali land improvement cycle are compared. If the former is longer than the latter, the time period of the saline-alkali land improvement cycle is used as a benchmark to obtain the consumption of saline-alkali substances in the entire improvement cycle. Conversely, the growth time of planted crops is used as a benchmark to obtain the consumption of saline-alkali substances in different trace element fertilizer adjustment time periods in the entire improvement cycle.

[0129] The consumption during the target period can be determined based on the following equation: ; in, Indicates the consumption during the target period. Indicates the consumption of saline and alkali substances at the initial time node. Indicates the end time node of the target period, Indicates the initial time node of the target period.

[0130] In some embodiments, the adjustment time of trace element fertilizer is based on the current trace element fertilizer content decreasing, resulting in a decrease in the consumption of saline-alkali substances, and topdressing operation is performed. In this case, it is also necessary to record the topdressing time node, and use the topdressing time node as the starting time of the trace element fertilizer adjustment time period, rather than determining it according to the growth cycle of the planted crops.

[0131] S137. Based on the saline-alkali substance consumption equation, the saline-alkali substance consumption within the saline-alkali land improvement period is obtained to obtain the predicted consumption at the target time.

[0132] The purpose of this step is to obtain the predicted consumption after obtaining the consumption of saline-alkali substances, taking into account that the possible trace element fertilizer formula used may not achieve the desired effect. Therefore, in the process, based on the determination of the predicted consumption, an adjustment basis can be obtained. This step is to obtain the predicted consumption and lay the foundation for subsequent comparison and adjustment work.

[0133] The saline-alkali substance consumption equation is obtained to obtain the saline-alkali substance consumption in each trace element fertilizer adjustment time period.

[0134] Among them, the saline-alkali land improvement period is used as the time period basis to obtain the consumption of saline-alkali substances in the time period, and then the consumption of saline-alkali substances in the period is obtained based on the length of the time period, and the result obtained is the predicted consumption.

[0135] Among them, the target time predicted consumption obtained is the same as the equation disclosed in step S134, which will not be repeated here.

[0136] S138. When the difference between the target period consumption and the target period predicted consumption is not less than a preset consumption deviation value, the periodic trace element fertilizer formula is adjusted based on the single element improvement speed.

[0137] The purpose of this step is to fully ensure that the actual improvement operations can meet the set index requirements within each saline-alkali land improvement cycle. When it is found that the periodic trace element fertilizer formula used cannot achieve the corresponding goals, the formula needs to be further adjusted to obtain better improvement results.

[0138] The obtained preset consumption deviation value may be set based on the professional knowledge of the technician.

[0139] In some embodiments, the difference between the target period consumption in the historical time and the target period predicted consumption is obtained, and the average of the difference is calculated, and the obtained difference result is the preset consumption deviation value.

[0140] Among them, the difference between the target period consumption and the target period predicted consumption in the current time period is obtained, and directly compared with the preset consumption deviation value. When it is found that the former is not lower than the latter, it means that there is a problem with the current periodic trace element fertilizer formula used, and it needs to be further adjusted.

[0141] Among them, when further adjusting the formula of periodic trace element fertilizer, it is necessary to obtain the improvement rate of a single element. This parameter represents that after the trace element is increased, the growth of the planted crops will be improved, and the consumption rate of saline-alkali substances will also increase. Therefore, in the specific adjustment, it is necessary to increase the amount of trace elements with a higher improvement rate of a single element.

[0142] In some embodiments, it is necessary to make comprehensive adjustments to the periodic trace element fertilizer formula. Specifically, the specific adjustment operations can be performed based on the experience of the technicians.

[0143] As described in step S140, the purpose of this step is to establish and adjust the formula of trace element fertilizer required for each improvement cycle in advance in order to achieve better saline-alkali land improvement effect, so that it can be immediately put into use when the corresponding improvement cycle start time node is reached. This requires the formula to be determined in advance. The purpose of this step is obviously to obtain the formula of trace element fertilizer for the next improvement cycle in advance, so as to achieve advance processing. Specifically: S141. Obtaining the improvement cycle target of the saline-alkali land, and obtaining the target consumption of saline-alkali substances in the saline-alkali land within the improvement cycle.

[0144] The purpose of this step is to be able to effectively consume the saline-alkali substances in the next cycle. It is necessary to determine the total amount of saline-alkali substances that need to be consumed within the time period, so as to set the consumption threshold.

[0145] Among them, the improvement cycle target of the saline-alkali land is obtained, and then the start and end time nodes of each cycle are directly determined, and based on the content of saline-alkali substances corresponding to the node, the difference is obtained, that is, the target amount of saline-alkali substances is obtained.

[0146] In some embodiments, if it is determined that the periodic trace element fertilizer formula used in the current cycle cannot achieve the required saline-alkali land improvement target, the difference between the actual improvement effect and the improvement target is obtained, and the difference is added to the improvement target in the next improvement cycle. This value is the correct improvement cycle target.

[0147] S142, performing numerical expansion processing on the target consumption of saline-alkali substances to obtain an expanded target consumption.

[0148] The purpose of this step is to achieve better saline-alkali land improvement effects. It is often necessary to ensure that in the prediction stage, the consumption of saline-alkali substances that the formula can obtain is higher than the target amount set in the cycle, so that the obtained formula has a higher margin and thus achieves better robustness.

[0149] Among them, the expanded processing parameters for the target consumption of saline-alkali land can be set based on specific standards or requirements.

[0150] S143. Based on the saline-alkali substance consumption equation and the expanded target consumption, an alternative trace element fertilizer formula is obtained.

[0151] The purpose of this step is that, in the application of trace element fertilizers, it is obviously not just one type of fertilizer that is applied, but rather a mixture of multiple trace element fertilizers. Therefore, after determining the goal of the next improvement cycle, multiple sets of formulas can be obtained based on the goal at the same time. Such formulas are essentially usable, but the actual effects achieved may be different and need to be screened.

[0152] Among them, the expanded target consumption is the dependent variable in the saline-alkali substance consumption equation, and the relevant parameters in the formula are independent variables. After obtaining the independent variable results, multiple formulas can be obtained.

[0153] S144, obtaining the growth cycle of the planted crop in the next improvement cycle, and obtaining the trace element fertilizer demand in the growth cycle.

[0154] The purpose of this step is that since the demand for trace elements of cultivated crops varies in different time periods, it is also necessary to consider the growth cycle of cultivated crops in the next improvement cycle and screen the alternative trace element fertilizer formulas based on this information.

[0155] Among them, the actual time of the next improvement cycle is obtained, the growth cycle of the crops planted in the next improvement cycle is determined, and the demand for trace elements of the crops in different growth cycles is determined.

[0156] In some embodiments, if it is found that the next improvement cycle spans two or more growth cycles of the crops, it is necessary to obtain the trace element fertilizer requirements of the crops in each growth cycle based on the growth cycle.

[0157] In some embodiments, only the minimum requirement of the cultivated crops for various trace element fertilizers needs to be obtained.

[0158] In some embodiments, it is also necessary to obtain the impact of fluctuations of different types of trace element fertilizers on the growth status of the cultivated crops during the next improvement cycle of the cultivated crops.

[0159] S145. Based on the trace element fertilizer demand and the alternative trace element fertilizer formula, obtain the trace element fertilizer formula for the next improvement period.

[0160] The purpose of this step is to select an optimal trace element fertilizer formula from all alternative trace element fertilizer formulas.

[0161] Among them, based on the comparison of all parameters of all alternative formulas and trace element fertilizer requirements, a trace element fertilizer formula that can meet the normal growth of cultivated crops is obtained.

[0162] Among them, if there are multiple formulas that can simultaneously meet the following two requirements: (1) ensuring the normal growth of crops; and (2) being able to achieve the requirements for improving saline-alkali land, these two requirements can be regarded as available formulas and one can be selected for use.

[0163] It should be noted that in the above steps S141 to S145, the result that can be obtained is the formula of the trace element fertilizer for the next cycle, but this formula is actually only the determination of multiple possible formulas, and for this type of formula, it can also be further optimized. Therefore, the present application also discloses a method for improving the formula of the trace element fertilizer for the next cycle, specifically: S146. Based on the growth history data of the planted crops, obtain the single element improvement rate of the planted crops in different growth cycles to obtain the periodic single element improvement rate.

[0164] The purpose of this step is to determine that for the next cycle formula, different trace elements have different effects on the consumption rate of saline-alkali substances. During the prediction process, it is difficult to determine the improvement rate of a single element based on real-time detection results. Therefore, historical data is needed to determine it.

[0165] Therein, the growth cycle of the planted crops in the next improvement cycle is obtained, and then the growth cycle is compared with the historical growth cycle of the planted crops for horizontal comparison.

[0166] Among them, the growth-promoting effect of all trace element fertilizers on planted crops during the same growth cycle in history is obtained, and the improvement speed of single elements is ranked.

[0167] The reason why the formula is not directly screened based on historical growth data is that the content of saline-alkali substances in the soil decreases during the continuous improvement of saline-alkali land. That is to say, although the crops are in the same growth cycle, the soil environment has changed greatly, making the historical formulas in the same growth cycle unavailable. However, the improvement rate of a single element of trace element fertilizer changes very little and can be ignored. Therefore, this parameter can be determined based on historical data.

[0168] S147. Based on the single element improvement speed of the cycle, adjust the formula of the trace element fertilizer for the next improvement cycle.

[0169] The purpose of this step is to further adjust the formula of trace element fertilizer for the next improvement cycle.

[0170] Among them, according to the obtained single element improvement rate of the cycle, find the trace element fertilizer that has the greatest impact on the growth rate of the planted crops.

[0171] Among them, the dosage of the trace element fertilizer with the highest hardness is increased to obtain a trace element fertilizer formula with a higher promoting effect.

[0172] In some embodiments, for the specific screening of the improvement speed of a single element, the specific value of the improvement speed of the single element can be adjusted according to the divided threshold or related requirements. The present application does not limit the screening requirements and goals.

[0173] As described in step S150, the purpose of this step is that in saline-alkali areas, environmental changes will also lead to changes in the content of saline-alkali substances, such as acid rain will increase acidity. Therefore, in the improvement of saline-alkali land, it is also necessary to pay attention to the changes in the content of saline-alkali soil substances caused by environmental changes, and then further adjust the formula. Specifically: S151. Obtaining the precipitation time of the saline-alkali land, and after the precipitation time of the saline-alkali land ends, obtaining the content of saline-alkali substances to obtain a sudden change in the content of saline-alkali substances.

[0174] The purpose of this step is to take into account that the saline-alkali content of saline-alkali land changes mainly due to precipitation, so it is necessary to determine the precipitation conditions and the saline-alkali content immediately after precipitation to achieve rapid adjustment of the formula.

[0175] Among them, after the precipitation in the saline-alkali land ends, a saline-alkali substance detection device is immediately used to obtain the saline-alkali substance content.

[0176] Among them, the areas within the saline-alkali land area are also divided according to the saline-alkali substance detection device. The specific division method is the same as the method disclosed in step S110, and will not be repeated here.

[0177] S152. Predict environmental change parameters of saline-alkali land, predict the precipitation of saline-alkali land and the content of saline-alkali substances in rainwater, predict the content of saline-alkali substances after precipitation time, and obtain the sudden change of saline-alkali substance content caused by environmental change.

[0178] The purpose of this step is to determine the change in saline-alkali substances by predicting the environmental parameters of saline-alkali land in the future, so as to adjust the formula and apply topdressing in advance.

[0179] Among them, for environmental change parameters, predictions are made based on technical means such as historically collected data, seasonal change indicators and weather forecasts.

[0180] Among them, the content of saline-alkali substances and the area division technology are the same as step S151 and will not be repeated here.

[0181] As described in step S160, the purpose of this step is to adjust the formula of trace element fertilizer in real time according to the sudden change in the content of saline-alkali substances to ensure the improvement effect of saline-alkali land. Specifically: S161. Based on the mutated saline-alkali substance content, obtain a saline-alkali substance content consumption value.

[0182] The purpose of this step is that after the introduction of a mutation in the content of saline-alkali substances, the consumption of saline-alkali substances in the corresponding time period has changed, and the formula needs to be determined based on this new value.

[0183] The occurrence time of the sudden change in the content of saline-alkali substances is obtained and accumulated with the corresponding improvement period to obtain the result.

[0184] In some embodiments, the sudden change in the content of saline-alkali substances occurs within a certain improvement cycle period. In this case, the time node of the sudden change in the content of saline-alkali substances is obtained and added to the existing content of saline-alkali substances to obtain the consumption of the content of saline-alkali substances.

[0185] In some embodiments, the mutated saline-alkali substance content can also be directly used as the saline-alkali substance content consumption value.

[0186] Among them, the so-called saline-alkali substance content consumption value refers to the saline-alkali substance content value that needs to be consumed during the saline-alkali land improvement period after a mutation in the saline-alkali substance content occurs.

[0187] S162. Based on the saline-alkali substance content consumption value, obtain a trace element fertilizer formula under the environmental influence.

[0188] The purpose of this step is to redefine the formula of trace element fertilizer after a sudden change in the content of saline-alkali substances occurs, and to place trace element fertilizer based on the redetermined formula.

[0189] The implementation of this step is the same as all the technical contents disclosed in steps S110 to S140, and will not be repeated here.

[0190] The beneficial effects of this application include: 1. Real-time adjustment of the formula of trace element fertilizer is achieved. The technical solution of the present application makes corresponding adjustments to the formula of trace element fertilizer according to the periodic target of the improvement of saline-alkali land area and the area of ​​the placement of trace elements. In addition, the adjustment process is based on the real-time acquisition of data from various sensors that have been set up, and then the formula is adjusted, thereby achieving real-time adjustment of the formula of trace element fertilizer.

[0191] 2. Quantitative adjustment of the formula of trace element fertilizer is achieved. In the technical solution of the present application, a correlation is established between trace element fertilizer and the consumption of saline-alkali substances in saline-alkali land, and a corresponding equation is established between the two. Therefore, in the adjustment of trace element fertilizer, based on the requirements for the consumption of saline-alkali substances and the corresponding equation, the quantitative determination and adjustment of the amount of trace elements required to be input in the saline-alkali land area can be achieved.

[0192] 3. Consideration of weather factors. In the technical solution of this application, the weather factors considered do not only analyze the dilution or enrichment effect that weather conditions may cause on trace element fertilizers, but analyze the impact of weather effects on planted crops. Then, based on this factor, the input amount of trace element fertilizers is determined, so that the formula of trace element fertilizers is adjusted accordingly.
