Variety breeding can increase the yield of tea, reduce the degree of its growth fear of pests and diseases, and ensure the quality and taste of tea. Variety breeding can promote the protection of tea diversity, avoid the singleness of tea species, and maintain the variety diversity and richness of tea genetic resources.

[0082] When there are tea seedlings whose quality is inferior to the second tea seedlings or whose yield is inferior to the first tea seedlings, iterative tea seedlings whose quality is not inferior to the second tea seedlings and whose yield is not inferior to the first tea seedlings are selected for re-iteration, and the tea seedlings obtained by iteration are used as target tea seedlings.

[0083] Compared with the prior art, the present invention has the following beneficial effects:

[0084] By forming a yield improvement plan, a quality improvement plan and obtaining a yield improvement correction plan, it is possible to obtain target tea seedlings that meet the needs through iteration. During breeding, factors related to quality and yield are considered separately to form corresponding breeding plans. At the same time, it is also considered that the improvement in quality may have an impact on yield. Therefore, the yield improvement plan is corrected to ensure that the breeding plan can cultivate the desired breeding. At the same time, in the final breeding, in order to ensure that the excellent characteristics can be maintained as much as possible during inheritance, iterative screening is carried out so that the offspring of the selected breeding can still maintain their excellent characteristics.

[0094] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0095] Reference Figure 1 As shown, a tea seedling breeding method based on improving tea quality and yield comprises:

[0096] Form at least one quality breeding indicator for quality;

[0097] Based on the tea quality and the tea yield, determining at least one quality-related influencing factor and at least one yield-related influencing factor respectively;

[0098] Obtain the target values ​​for tea quality and yield;

[0099] Based on the production target value and production-related influencing factors, formulate a production improvement plan;

[0100] Form a quality improvement plan based on quality target values ​​and quality-related influencing factors;

[0101] Obtain the impact value of the quality improvement plan on the output target value;

[0102] The yield improvement plan is modified based on the weakening impact value to obtain a modified yield improvement plan;

[0103] Cultivating tea seedlings using the yield improvement correction plan and the quality improvement plan to form at least one breeding group, wherein the breeding group includes a preset number of tea seedlings;

[0104] Based on the quality breeding index, the quality value of the breeding group is calculated to obtain the yield value of the breeding group;

[0105] Select the breeding group with the largest quality value from among the breeding groups whose yield values ​​are greater than the yield target value to obtain the characteristic breeding group;

[0106] The tea seedlings in the characteristic breeding group are iteratively cultivated, and the tea seedlings in the characteristic breeding group are screened during the iterative cultivation process to obtain target tea seedlings.

[0107] Distinguish the factors that affect quality and yield, because the two will conflict to a certain extent, that is, the parameters for improving quality may affect yield, and of course, the increase in yield may also affect quality. According to this influence, after revising the yield improvement plan, the quality improvement plan is revised, and after revising the quality improvement plan, the yield improvement plan is revised again. This cycle repeats, and although a more appropriate plan can be finally obtained, it will increase the time for the plan to be formed. In this plan, in order to improve efficiency, the quality target value obtained can be set larger than the actual demand, thereby offsetting the impact of yield improvement on quality, and the impact of quality improvement on yield is corrected by the yield improvement correction plan, thereby ensuring that the formed plan can select the required breeding;

[0108] When formulating yield improvement plans and quality improvement plans, we not only consider the impact of each factor, but also the cost of reaching the numerical value of that factor. Obviously, different fertilizers, temperature controls, and sunlight controls all require certain costs. When breeding, we not only need to control the effects, but also need to consider it from an economic perspective. Therefore, this situation is taken into consideration in this plan.

[0109] Reference Figure 2 As shown, forming at least one quality breeding indicator for quality includes the following steps:

[0110] Based on big data, at least one indicator that affects the quality of tea is obtained as a quality breeding indicator, and the quality breeding indicator involves the appearance, smell and taste of tea;

[0111] The AHP hierarchical analysis method was used to generate indicator weights for quality breeding indicators.

[0112] It is very easy to evaluate the yield, that is, just count the yield of each tea plant, but the evaluation of quality is more complicated. It is necessary to determine the quality-related quality breeding indicators. At the same time, since the quality breeding indicators play different roles in quality, in order to evaluate the quality of tea, it is necessary to form quality breeding indicators and determine their indicator weights.

[0113] Reference Figure 3 As shown, based on the tea quality and the tea yield, determining at least one quality-related influencing factor and at least one yield-related influencing factor respectively includes the following steps:

[0114] Based on the big data, at least one cultivation factor affecting tea development is obtained, where the cultivation factor is composed of light, water, temperature, soil type and fertilizer type, wherein there is at least one soil type and at least one fertilizer type, and the light factor includes light intensity and light duration;

[0115] Select one of the at least one cultivation factor as the target cultivation factor, and use the remaining cultivation factors as non-target cultivation factors;

[0116] A cultivation control group is set, in which at least one tea seedling is set, and the non-target cultivation factors of the tea seedlings in the cultivation control group are all the same and the target cultivation factors are all different;

[0117] When the quality of tea seedlings in the cultivation control group is different, the target cultivation factor is taken as the quality-related influencing factor;

[0118] Use the first quality formula to calculate the quality value of tea seedlings in the cultivation control group;

[0119] The tea seedlings with the smallest quality value in the cultivation control group are used as characteristic tea seedlings, and the remaining tea seedlings in the cultivation control group are used as non-characteristic tea seedlings;

[0120] Use the quality impact formula to calculate the quality impact factor of the quality-related impact factor;

[0121] When there are differences in tea seedling yields in the cultivation control group, the target cultivation factor is taken as the yield-related influencing factor;

[0122] The tea seedlings with the smallest yield in the cultivation control group are used as the calibration tea seedlings, and the remaining tea seedlings in the cultivation control group are used as non-calibration tea seedlings;

[0123] Using the yield impact formula, calculate the yield impact factor of the yield-related impact factor;

[0124] When the target cultivation factor traverses at least one cultivation factor, the determination of at least one quality-related influencing factor and at least one yield-related influencing factor is completed;

[0125] The first quality formula is as follows:

[0126]

[0127] Among them, A is the quality value of tea seedlings in the cultivation control group, n is the total number of at least one quality breeding index, i is the subscript, a i is the value of the i-th quality breeding index of tea seedlings in the cultivation control group, b i is the indicator weight of the i-th quality breeding indicator;

[0128] The quality impact formula is as follows:

[0129]

[0130] Among them, B is the quality influencing factor of the quality-related influencing factor, j is the subscript, m is the total number of non-characteristic tea seedlings, A j is the quality value of the jth non-characteristic tea seedling, A0 is the quality value of the characteristic tea seedling, C j is the value of the target cultivation factor of the jth non-characteristic tea seedling, and C0 is the value of the target cultivation factor of the characteristic tea seedling;

[0131] The yield impact formula is as follows:

[0132]

[0133] Where D is the yield influencing factor of yield-related influencing factors, k is a subscript, p is the total number of non-calibrated tea seedlings, E k is the value of the target cultivation factor of the kth non-calibrated tea seedling, E0 is the value of the target cultivation factor of the calibrated tea seedling, F k is the yield value of the kth non-calibrated tea seedling, and F0 is the yield value of the calibrated tea seedling.

[0134] Here, not only at least one quality-related influencing factor and at least one yield-related influencing factor are determined, but more importantly, the yield influence factor of the yield-related influencing factor and the quality influence factor of the quality-related influencing factor are determined. Since the yield influence factor and the quality influence factor are similar, taking the yield influence factor as an example, the yield influence factor is used to calculate the impact of the change in the numerical value of the yield-related influencing factor on the yield. Therefore, the change in the yield is used as the denominator in the yield influence formula, and the change in the numerical value of the yield-related influencing factor is used as the numerator. Therefore, the yield influence factor can be used to calculate the change in yield according to the change in the numerical value of the yield-related influencing factor relative to 0.

[0135] Reference Figure 4 As shown, based on the production target value and production-related influencing factors, forming a production improvement plan includes the following steps:

[0136] Segmenting the value range of the yield-related influencing factor to obtain at least one identification point, and pairing the at least one identification point with the yield-related influencing factor;

[0137] Forming at least one yield preparation plan, the yield preparation plan is composed of all yield-related influencing factors, and the value of the yield-related influencing factor is one of the values ​​of the corresponding at least one identification point;

[0138] Use the yield formula to calculate the yield value of the yield preparation plan;

[0139] Select the production reserve plan with a production value greater than the production target value as the production alternative plan;

[0140] The cost of cultivating according to the parameters in the yield alternative plan is calculated as the yield cost;

[0141] Select the production alternative with the lowest production cost as the production increase plan;

[0142] The yield formula is as follows:

[0143]

[0144] Among them, H is the output value of the output preparation plan, r is the subscript, s is the total number of output-related influencing factors, and D r is the yield impact factor of the rth yield-related influencing factor, I r It is the value of the rth yield-related influencing factor in the yield preparation plan.

[0145] When formulating a production increase plan, not only the production target value is considered, that is, the output generated by the formed plan must be higher than the production target value, but also the cost needs to be considered, so the production alternative plans that meet the production demand are screened;

[0146] The calculation of the output value of each yield preparation plan depends on the multiplication and accumulation of the numerical values ​​of the yield-related influencing factors and the corresponding yield influencing factors. Because the numerical value of each yield-related influencing factor can be regarded as a change relative to 0, the output corresponding to the numerical value of each yield-related influencing factor can be obtained. Therefore, by accumulating them, the output value of the yield preparation plan can be obtained. This is the principle of the yield formula.

[0147] Reference Figure 5 As shown, based on the quality target value and quality-related influencing factors, the quality improvement plan includes the following steps:

[0148] Segmenting the value range of the quality-related influencing factor to obtain at least one sampling point, and pairing the at least one sampling point with the quality-related influencing factor;

[0149] Forming at least one quality preparation plan, the quality preparation plan is composed of all quality-related influencing factors, and the value of the quality-related influencing factor is one of the values ​​of the corresponding at least one sampling point;

[0150] Using the second quality formula, calculate the quality value of the quality preparation plan;

[0151] Select the quality preparation plan with a quality value greater than the quality target value as the quality alternative plan;

[0152] The cost of cultivating according to the parameters in the quality alternative plan is calculated as the quality cost;

[0153] Select the quality alternative with the lowest quality cost as the quality improvement plan;

[0154] The second quality formula is as follows:

[0155]

[0156] Among them, J is the quality value of the quality preparation plan, t is the subscript, u ​​is the total number of quality-related influencing factors, N t is the quality impact factor of the tth quality-related influencing factor, M t It is the value of the tth quality-related influencing factor in the quality preparation plan.

[0157] When formulating a quality improvement plan, not only the quality target value is considered, that is, the quality produced by the formed plan must be higher than the quality target value, but also the cost needs to be considered, so the quality alternatives that meet the quality requirements are screened;

[0158] The calculation of the quality value of each quality preparation plan depends on the multiplication and accumulation of the numerical values ​​of the quality-related influencing factors and the corresponding quality influencing factors. Because the numerical value of each quality-related influencing factor can be regarded as a change relative to 0, the quality corresponding to the numerical value of each quality-related influencing factor can be obtained. Therefore, by accumulating them, the quality value of the quality preparation plan can be obtained. This is the principle of the quality formula.

[0159] Reference Figure 6 As shown, obtaining the weakening effect value of the quality improvement plan on the output target value includes the following steps:

[0160] Based on historical data, the quality-related influencing factors that have a significant impact on the production of reductions are used as target quality-related influencing factors;

[0161] Based on historical data, obtain the output reduction value when the unit value of the influencing factors associated with the target quality changes;

[0162] The values ​​of the target quality-related influencing factors that appear in the quality improvement plan are multiplied and added with the corresponding output reduction values ​​to obtain the weakening impact value.

[0163] When the quality is improved, it will inevitably have an impact on the yield. Therefore, if the plan is not revised, it will be difficult to cultivate the required breeding. For this reason, the yield improvement plan is revised. When correcting, the weakening impact value will be evenly distributed to each yield-related influencing factor. Therefore, divided by s in the compensation formula, so by changing each yield-related influencing factor, the impact of the weakening impact value is offset. The part of the weakening impact value allocated to each yield-related influencing factor is divided by the yield influence factor, and the compensation value of the yield-related influencing factor can be obtained. This is the principle of the compensation formula.

[0164] Reference Figure 7 As shown, the yield improvement plan is corrected based on the weakening impact value, and the yield improvement correction plan includes the following steps:

[0165] Use the compensation formula to calculate the compensation value of the yield-related influencing factors;

[0166] The compensation value is added to the value of the corresponding yield-related influencing factor in the yield improvement correction plan to obtain the compensation value of the yield-related influencing factor, and the yield improvement correction plan is obtained by summarizing;

[0167] The compensation formula is as follows:

[0168]

[0169] Among them, L is the compensation value of the yield-related influencing factors, R is the weakening impact value, s is the total number of yield-related influencing factors, and D is the yield impact factor of the yield-related influencing factors.

[0170] Reference Figure 8 As shown, based on the quality breeding index, calculating the quality value of the breeding group includes the following steps:

[0171] The second quality formula is used to calculate the quality value of the selected seedlings in the breeding group;

[0172] The quality values ​​of the selected seedlings in the breeding group are averaged to obtain the quality value of the breeding group;

[0173] The second quality formula is as follows:

[0174]

[0175] Where G is the quality value of tea seedlings in the cultivation control group, n is the total number of at least one quality breeding index, q is the subscript, and f q is the value of the qth quality breeding index of tea seedlings in the cultivation control group, b q is the indicator weight of the qth quality breeding indicator.

[0176] Reference Fig. 9 As shown, screening tea seedlings in the characteristic breeding group during the iterative cultivation process to obtain target tea seedlings includes the following steps:

[0177] The tea seedling with the worst yield in the characteristic breeding group is used as the first tea seedling;

[0178] The tea seedlings with the worst quality in the characteristic breeding group are used as the second tea seedlings;

[0179] Iterative cultivation is performed using tea seedlings in the characteristic breeding group to obtain at least one iterative tea seedling;

[0180] When there are tea seedlings whose quality is inferior to the second tea seedlings or whose yield is inferior to the first tea seedlings, iterative tea seedlings whose quality is not inferior to the second tea seedlings and whose yield is not inferior to the first tea seedlings are selected for re-iteration, and the tea seedlings obtained by iteration are used as target tea seedlings.

[0181] Here, the reason for iterative breeding is that some qualified breeding offspring may not be able to maintain their excellent characteristics. Therefore, in order to avoid this situation, it is necessary to select breeding that can inherit excellent characteristics during iteration. The offspring of these breedings are more likely to maintain excellent characteristics, and in order to enhance this possibility, the above-mentioned iterative screening process can be repeated many times.

[0182] Furthermore, the present solution also proposes a storage medium on which a computer-readable program is stored. When the computer-readable program is called, the above-mentioned tea seedling breeding method based on improving tea quality and yield is executed.

[0183] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).

[0184] To sum up, the advantages of the present invention are: by forming a yield improvement plan, a quality improvement plan and obtaining a yield improvement correction plan, it is possible to obtain target tea seedlings that meet the needs through iteration. During breeding, factors related to quality and yield are considered separately to form corresponding breeding plans respectively. At the same time, it is also considered that the improvement in quality may have an impact on the yield. Therefore, the yield improvement plan is corrected to ensure that the breeding plan can cultivate the desired breeding. At the same time, in the final breeding, in order to ensure that the excellent characteristics can be maintained as much as possible during inheritance, iterative screening is carried out so that the offspring of the selected breeding can still maintain their excellent characteristics.

[0185] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
