Description

Technical Field

[0001] The present application relates to the technical field of agricultural equipment, and in particular to a quantitative fertilization device for fruit planting. Background Art

[0002] Fruit trees are perennial woody plants with long growth cycles. Throughout their lifecycles, they undergo a process of growth, fruiting, renewal, and aging. Within their annual cycle, they undergo distinct phenological phases, including budding, shoot development, flowering, fruiting, maturity, and dormancy. Fertilization for fruit trees has unique characteristics during these different growth periods, as their nutritional requirements differ from those of field crops and vegetables.

[0003] First, to meet the needs of their above- and below-ground growth and the large annual production of fruit, fruit trees absorb large quantities of nutrients from the soil each year, especially mature trees. Consequently, fruit trees require a high fertilizer requirement, necessitating regular annual fertilization. Second, fruit trees have a long growth cycle, with the same plant typically growing continuously for decades on the same plot of land. Because fruit trees maintain a fixed location and continuously absorb nutrients, they often over-deplete certain nutrients in the soil. Furthermore, fruit trees are perennial crops, and their nutritional needs vary at different times of the year. Nitrogen requirements are high in the early stages of growth, then decrease, requiring additional nitrogen after the fruit is harvested. Phosphorus requirements increase during the growth period, but remain relatively stable later in life. Potassium requirements are low in the early stages of growth, but increase in the middle stages.

[0004] Given the aforementioned fertilization characteristics of fruit trees, planting fruit trees often requires regular, quantitative, and on-demand fertilization to ensure healthy growth and sufficient, high-quality fruit. Existing fruit tree planting methods, after initial application of base fertilizer, often rely on manual supplemental fertilization in later stages. However, since most fruit tree plantings are currently centralized, covering large planting areas, and some orchards are located in mountainous areas with complex terrain, manual fertilization is labor-intensive and extremely costly. Summary of the Invention

[0025] The present application is further described in detail below with reference to the accompanying drawings and examples.

[0026] like Figure 1 and Figure 2 As shown, the present application designs a quantitative fertilization device for fruit planting, which includes a spraying mechanism. A spraying mechanism can be arranged at each fruit tree to spray liquid fertilizer on the fruit tree in a timely and quantitative manner.

[0027] The spraying mechanism includes a fertilizer storage tank 1 arranged next to a single fruit tree, and a plurality of rotary sprinklers 2 arranged along the circumference of the trunk of the single fruit tree. The plurality of rotary sprinklers 2 are connected to the fertilizer storage tank 1 through a pipeline. Liquid fertilizer is supplied by the fertilizer storage tank 1, and the rotary sprinklers 2 perform spraying operations.

[0028] The pipeline connecting the fertilizer storage tank 1 and the multiple rotating spray heads 2 is equipped with a spray pump 3, a spray valve 4, and a flow meter 5, arranged in sequence from the fertilizer storage tank 1 to the multiple rotating spray heads 2. The spray pump 3 and spray valve 4 control the spraying of liquid fertilizer, while the flow meter 5 monitors the flow rate of the liquid fertilizer and obtains the spray volume parameter.

[0029] like Figure 4 As shown, the quantitative fertilization equipment also includes a control part. The control part includes a control computer 10, which is connected to a power supply. The spray pump 3, spray valve 4 and flow meter 5 of each spray mechanism are electrically connected to the control computer 10. The control computer 10 uses an existing computer as a body, and a control program can be installed inside for control. The control program can control the opening and closing of the spray valve 3 and the spray pump 4 according to the flow parameters of the liquid fertilizer sprayed monitored by the flow meter 5, thereby achieving quantitative fertilization; at the same time, the control program can also set the date and time of spraying fertilizers, so that timed fertilization can be achieved. The above-mentioned control program can purchase similar control software currently available on the market, and the above-mentioned control can be achieved through parameter setting.

[0030] The pumps used in this application are all electric pumps, the valves are all solenoid valves, and the flow meter 5 and the liquid level meter 9 are all electronic monitoring meters.

[0031] Example 1

[0032] This embodiment is a quantitative fertilization device for fruit planting suitable for small orchards, and its overall structure is basically the same as the above-mentioned main structure of this application.

[0033] In this embodiment, each spray mechanism has three or five rotating nozzles 2, which are evenly arranged along the circumference of the trunk of a single fruit tree. The more the number of rotating nozzles 2, the more evenly the liquid fertilizer is sprayed.

[0034] The distance between the rotating nozzle 2 of this embodiment and the corresponding fruit tree trunk is set within a range of 50 to 80 cm, which can be adjusted according to the different fruit tree varieties. The distance between the rotating nozzle 2 of this embodiment and the ground is set within a range of 25 to 40 cm, which can also be adjusted according to the different fruit tree varieties. Such settings enable the rotating nozzle 2 to cover a more appropriate spraying range, so that the sprayed liquid fertilizer can basically cover the entire root system of the fruit tree, promote the fruit tree's absorption of nutrients, and promote healthier growth of the fruit tree.

[0035] When using the fruit planting quantitative fertilization device of this embodiment, orchard workers can configure the corresponding liquid fertilizer according to the variety of fruit trees planted and the growth period, and fill it into the fertilizer storage tank 1 of each spraying mechanism in accordance with the corresponding scientific standards for planting. Then, they can set the spraying time parameters and the spraying amount parameters for each spraying on the control computer 10. After turning on the device, the computer can spray the liquid fertilizer at a fixed time and fixed amount according to the parameters.

[0036] Example 2

[0037] This embodiment is a fruit planting quantitative fertilization device suitable for intensive planting in mountain fruit planting areas or large orchards. The spraying mechanism arranged at each fruit tree is basically the same as that in Example 1.

[0038] This embodiment is provided with a fluid replenishing device, such as Figure 3 As shown, the rehydration device of this embodiment includes a main fertilizer tank 6 equipped with a main drainage pipe. The fertilizer storage tank 1 of each spray mechanism installed on the fruit tree in this embodiment is connected to the main drainage pipe via a rehydration branch pipe, forming a rehydration pipeline. This allows the liquid fertilizer in the main fertilizer tank 6 to be delivered to the fertilizer storage tank 1 of each spray mechanism via the rehydration pipeline.

[0039] In this embodiment, a main pump 7 is provided on the drainage main pipe; a liquid level gauge 9 is provided in the fertilizer storage tank 1 of each spraying mechanism, and a tank valve 8 is provided on the liquid replenishment branch pipe of the fertilizer storage tank 1 of each spraying mechanism.

[0040] The master pump 7 of this embodiment, as well as the level gauge 9 and tank valve 8 of each spray mechanism, are also electrically connected to the control computer 10. The power supply of this embodiment is a solar photovoltaic power supply 11, which is conducive to reducing energy consumption.

[0041] In the above-mentioned design of this embodiment, during refilling, the liquid level meter 9 of each spraying mechanism can monitor the liquid level of the fertilizer storage tank 1; when the liquid level reaches the upper limit, the tank valve 8 can be closed, so that the refilling of the fertilizer storage tank 1 can be terminated, while the refilling of other spraying mechanisms will not be affected.

[0042] When the fruit planting quantitative fertilization equipment of this embodiment is used, the orchard staff can configure the corresponding liquid fertilizer and fill it into the total fertilizer tank 6 according to the variety of fruit trees planted and the growth period, in accordance with the corresponding scientific standard requirements of planting, and then set the spraying time parameters and the spraying amount parameters for each spraying on the control computer 10.

[0043] After turning on the equipment, the computer can set the timing and quantity of liquid fertilizer spraying according to the parameters.

[0044] When the liquid level in the fertilizer storage tank 1 of a spray mechanism is insufficient, the liquid level meter 9 will monitor the parameters and send them to the control computer 10, which will control the master pump 7 to open and start liquid replenishment. At this time, the liquid level meter 9 of each fertilizer storage tank 1 of the spray mechanism will monitor the liquid level data and provide real-time feedback to the control computer 10. When the liquid level meter 9 of a single spray mechanism detects that the liquid level has reached the upper limit, the control computer 10 will control the tank valve 8 to close based on the feedback parameters, and the spray mechanism will stop replenishing liquid. When all spray mechanisms have completed replenishment, the control computer 10 controls the master pump 7 to close, and replenishment stops.

[0045] This embodiment can not only realize the automatic fertilization of fruit trees at a fixed time and in a fixed quantity, but also realize the automatic control of liquid fertilizer replenishment, which can further reduce labor costs.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
