Description

Technical Field

[0001] The invention relates to the technical field of fruit tree planting, and in particular to an integrated orchard no-tillage water-fertilizer-weeding system, method and application. Background Art

[0002] Fruit tree planting is a complex and delicate process involving many aspects, including soil management, fertilizer and water management, shaping and pruning, pest and disease control, etc. Soil management includes soil type and improvement, soil cover and moisture conservation, fertilizer and water management includes fertilization and irrigation, shaping and pruning includes tree shape cultivation and pruning methods, pest and disease control includes preventive measures, chemical control, as well as variety selection and planting time, grafting technology, cold protection measures, etc. Therefore, fruit tree planting requires comprehensive consideration of multiple aspects, and scientific planting techniques and management methods need to be mastered in order to improve the yield and quality of fruit trees and achieve sustainable development of orchards.

[0003] Currently, after fruit trees are planted, fruits are usually grown and harvested in one year. During this one-year period, fertilizing, irrigating, and weed control are necessary links in the planting operation. The operations in each link are highly correlated to the growth of fruit trees and fruits, the impact on the land, and the control of planting costs.

[0004] At present, in order to improve the efficiency of weeding, machines are used for orchard weeding. When the machines are rolling in the orchard, they are very likely to cause mechanical damage to the root system of the fruit trees, such as root injury and root breakage. At the same time, the weight of the agricultural machinery itself is likely to cause the surface of the land to be compacted when moving in soft soil, which in turn affects the effective absorption of the fruit tree roots when applying solid fertilizers and water fertilizers.

[0005] In order to solve the problems of large labor consumption and root damage in artificial fertilization (artificial fertilization usually uses solid granular fertilizers, and fertilization requires digging a landfill pit at the root of the fruit tree to bury the fertilizer, and the excavation process is very easy to cause damage to the root system of the fruit tree, such as root breakage), as well as long artificial fertilization cycle, which affects the best absorption point of the fruit tree (if the tree does not obtain fertilizer nutrition in time during the critical growth period, and the solid fertilizer nutrients are released slowly, the growth of the fruit tree will be hindered, affecting the fruit tree fruiting cycle and the maturity quality of the fruit), a water-fertilizer integrated fertilization method has been adopted. This method requires a matching fertilizer dissolving system to add fertilizer to multiple large tanks and dissolve it in water, and then the fruit trees are sprayed and fertilized through a pressurized system and water and fertilizer pipes laid in the orchard. The following problems exist during its use: (1) The overall cost of the fertilizer dissolving system is high and the investment is large, which is not conducive to the purchase and use of small-scale growers (resulting in the current manual fertilization). Large fertilizer dissolving tanks require a separate fertilizer dissolving room. The fertilizer dissolving system is not easy to effectively and conveniently spray the dissolved water and fertilizer in planting areas with variable terrain; (2) When adding fertilizer to the dissolution tank for dissolution, it is very easy to reach dissolution saturation, that is, incomplete dissolution, and there are undissolved solid granular fertilizers. In the process of sprinkler irrigation through water bags, the sprinkler ports are usually small, which can easily cause blockage of the water bag sprinkler ports. The water bags are laid along the length of the fruit trees, and a single water bag is used to irrigate more fruit trees. In the case of weeds blocking the sprinkler ports, it is impossible to effectively know whether the fertilizer is blocking the sprinkler ports, resulting in some fruit trees not being able to obtain effective fertilization after the sprinkler ports are blocked, thereby affecting the growth of fruit trees and fruits; (3) Weeds in the root area of ​​fruit trees grow faster on the basis of absorbing fertilizers, resulting in the weeds blocking the sprinkler ports of the water and fertilizer bags for sprinkler irrigation, resulting in a decrease in sprinkler irrigation volume, an increase in sprinkler irrigation time, a decrease in the amount of water and fertilizer absorbed by the roots of the fruit trees, and part of the water and fertilizer being wasted by sprinkler irrigation outside the roots of the fruit trees. At the same time, it promotes the growth of weeds, which requires manual weeding and increases planting costs; (4) The existing high-tower soluble fertilizers and general solid fertilizers are not easy to dissolve quickly. When concentrated fertilization is carried out in large planting areas, it will seriously affect the efficiency of fertilization operations; As fruit trees enter the high temperature period of summer, high evaporation leads to large irrigation volumes and serious water waste, which increases costs during the irrigation process. Therefore, during the one-year period when fruits mature, multiple planting operations are subject to certain constraints, which have a significant impact on the growth of fruit trees and fruits, as well as the increase in land and costs. Summary of the invention

[0006] In view of the above-mentioned problems, the present invention aims to provide an integrated orchard no-tillage water-fertilizer and weeding system and method, which solves the problems of root damage caused by current single mechanical tillage, high investment cost of water-fertilizer integration and long fertilization cycle, easy blockage of sprinkler outlets due to dissolved saturation, easy obstruction of sprinkler outlets by weeds when weeds are not removed, and high planting cost due to frequent manual weeding, large evaporation after weeding, and increased irrigation water cost, etc. At the same time, the no-tillage water-fertilizer and weeding system has a low cost, and can be invested and used by both large-scale or small-scale fruit farmers, and thus has significant benefits in fruit tree planting.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] See attached Figures 1 to 8 The integrated orchard no-tillage water, fertilizer and weed control system shown includes: The assembly mechanism is used to connect and assemble with a water outlet component to obtain a water source. The specific structure of the assembly mechanism is as follows Figure 2 As shown, it includes but is not limited to an assembly head 2 that is detachably connected to the water outlet pile 1 and the power pump body, and the other end of the assembly head 2 is fixedly connected to the fertilizer processing mechanism. Among them, the water outlet pile 1 is a highly automated irrigation water source system, which is evenly arranged and covered in the fruit tree 14 planting area. The assembly head 2 can be directly assembled and connected with the water outlet pile 1 to quickly obtain water. At the same time, the uniform arrangement of the water outlet pile 1 can greatly save the overall configuration length for the water fertilizer weeding system of this application.

[0029] For traditional canal irrigation planting areas where water outlet piles 1 are not arranged, a water pump can be selected to access the canal to obtain water, and the assembly head 2 of the present application can be connected to the water pump port to quickly obtain water. Therefore, the present application can obtain water through the assembly head 2 in the water outlet pile 1 or canal irrigation mode. Compared with the current large-scale multi-tank dissolution system of water and fertilizer integration, it can save the demand for site and has great convenience and flexibility in operation. After the assembly head 2 is connected to the water outlet pile 1 or the water pump, water can be quickly obtained for fertilization and irrigation operations. Compared with the current water-fertilizer integration system, it can significantly reduce the investment of growers, and can achieve low-cost equipment for growers, reduce labor and facilitate operation and implementation.

[0030] On the basis of obtaining the water source through the assembly head 2 as mentioned above, the present application also discloses a fertilizer processing mechanism, which is used to process the fertilizer to a low-osmotic state, that is, to solve the saturation that is very easy to exist in the current water-fertilizer integrated system when dissolving the fertilizer, which may cause the sprinkler outlet to be blocked in the subsequent sprinkler irrigation and affect the amount of fertilizer absorbed by the fruit tree 14. At the same time, the treated fertilizer is driven by the water source to flow evenly, that is, the treated fertilizer is driven by the water source to flow to the fruit tree 14 for infiltration irrigation. Compared with the current sprinkler irrigation, the infiltration irrigation can reduce the flow rate of water and fertilizer, thereby achieving a state of slow absorption by the fruit tree 14, and at the same time can effectively increase the infiltration irrigation depth to further improve the effective fertilizer absorption of the fruit tree 14.

[0031] The specific structure of the fertilizer processing organization is as follows Figure 1 As shown, it includes a processing bin 3, in which a grinding and dissolving device for grinding granular fertilizer to a state that can be infiltrated is arranged, and the assembly head 2 is arranged on both sides of the processing bin 3 opposite to the infiltration and weeding mechanism and is connected to the processing bin 3. The fertilizer is added to the processing bin 3 and ground by the grinding and dissolving device, and the size of the ground particles is smaller than the aperture of the infiltration hole 12a described later, and the ground fertilizer is further dissolved after obtaining water source and entering the processing bin 3 through the assembly head 2, thereby effectively avoiding the blockage of the infiltration port during the later infiltration, and ensuring that each fruit tree 14 can be fully infiltrated and absorbed fertilizer. The grinding and dissolving device continuously grinds the fertilizer added to the processing bin 3, and the ground fertilizer is output from the other side of the processing bin 3 under the drive of the water source, and flows through the infiltration bag 12 described later, and then realizes infiltration irrigation to the corresponding fruit tree 14 through multiple infiltration holes 12a. The water source drives the ground fertilizer to fully dissolve the fertilizer during the flow. Compared with the current water-fertilizer integrated system that sprays the fertilizer after it is completely dissolved in the dissolution tank, the present application saves the time spent on the static dissolution process, thereby greatly improving the fertilization efficiency of the fruit trees 14.

[0032] At the same time, the grinding and dissolving device adjusts its grinding speed according to the flow rate of the connected water source, so that the water source flow rate matches the amount of fertilizer driven and dissolved, thereby effectively solving the problem of dissolution saturation that is very easy to occur during static dissolution in the dissolution tank, as well as the problem of blockage of the sprinkler outlet due to incomplete dissolution.

[0033] Specifically, the grinding and dissolving device structure is as follows Figure 3-5As shown, the processing bin body 3 is set as a three-layer structure, the bottom layer is a water flow power bin 31, the middle layer is a grinding bin 32, a closed grinding chamber 321 is also arranged in the grinding bin 32, and the upper layer is a storage bin 33. One side of the water flow power bin 31 is connected to a water inlet pipe 4, and the other side is connected to a water outlet pipe 5. Among them, an impeller 6 is arranged in the water flow power bin 31, and the rotating shaft 7 of the impeller 6 extends upward into the closed grinding chamber 321. A centrifugal moving grinding plate 81 is sleeved on the outer wall of the top end of the rotating shaft 7, and a static grinding plate 82 is arranged on the top of the closed grinding chamber 321. The static grinding plate 82 is a hollow annular structure and is connected with the storage bin 33, and a grinding gap a is reserved between the centrifugal moving grinding plate 81 and the static grinding plate 82; grinding water inlet holes b1 are arranged at intervals on the circumferential surface of the rotating shaft 7 located in the water flow power bin 31, and a grinding gap a is arranged inside the rotating shaft 7. The grinding water inlet b1 is connected and extends to the dissolving water pipe 9 in the storage bin 33; a feeder 10 (whose outer wall is preferably a spiral structure) located in the storage bin 33 and connected to the dissolving water pipe 9 is arranged at the top of the rotating shaft 7, and a grinding water outlet b2 connected to the dissolving water pipe 9 is opened on the top outer wall of the feeder 10; a feeding channel c connected to the grinding gap a is reserved between the centrifugal grinding disc 81, the feeder 10 and the rotating shaft 7; and a liquid fertilizer conveying pipe 11 horizontally penetrating the inlet and outlet pipes 5 is also arranged at the bottom of the closed grinding chamber 321. The working principle of the grinding and dissolving device is as follows: The assembly head 2 at the end of the water inlet pipe 4 is connected to the water outlet pile 1 or the water pump of the canal irrigation, and the water source enters the water flow power bin 31 and flows out toward the water outlet pipe 5. At the same time, the water source drives the impeller 6 to rotate, and the impeller 6 drives the centrifugal moving grinding disc 81 and the feeder 10 to rotate through the rotating shaft 7. At the same time, the water source enters the dissolving water pipe 9 through the grinding water inlet hole b1 on the bottom side of the rotating shaft 7, and the water source flows out from the grinding water outlet hole b2 of the feeder 10 to contact the granular fertilizer in the storage bin 33, so as to improve the fertilizer feeding. The water-dissolved fertilizer is transported downward to the closed grinding chamber 321 through the transport channel c under the action of the feeder 10 rotating along with the rotating shaft 7. The hydrolyzed granular fertilizer passes through the transport channel c and enters the grinding gap a between the static grinding plate 82 and the centrifugal dynamic grinding plate 81 for grinding. The ground liquid fertilizer enters the water outlet pipe 5 through the liquid fertilizer delivery pipe 11 (the bottom surface of the centrifugal static grinding plate 82 has the same structure as the surface of the static grinding plate 82, and has a plurality of spirally arranged centrifugal grooves along the axial direction, such as Figure 4In the structure shown, after the rotary grinding process, the ground liquid fertilizer is transported into the liquid fertilizer transport pipe 11 by centrifugal force through the centrifugal groove on the bottom of the centrifugal static grinding plate 82 during the downward flow of the liquid fertilizer, and then driven and mixed by the water flow in the outlet pipe 5 to enter the infiltration bag 12 described later, and the liquid fertilizer infiltration irrigation of the fruit tree 14 is achieved through a plurality of infiltration holes 12a on the infiltration bag 12, so that the grinding and dissolving device can realize the initial hydrolysis, grinding and dissolving, and centrifugal transportation of the granular fertilizer under the flow drive of the water source, so that the grinding and dissolving process of the granular fertilizer is carried out synchronously with the water flow, thereby solving the problems of the time spent on dissolving the fertilizer in the dissolution tank in the current water-fertilizer integrated system, the solubility saturation that is very likely to occur in the dissolution process, and the granular fertilizer that is not dissolved after saturation that is very likely to cause blockage of the sprinkler port in the sprinkler irrigation.

[0034] Different water outlet piles or canal irrigation use pumps with different water flow rates, and in order to match the grinding amount of granular fertilizer according to the water flow rate, such as Figure 3 As shown, a plug plate 15 is provided in the storage bin 33 and in contact with the grinding bin 32, the outer end of which is located outside the storage bin 33 for easy operation, while the inner end can be extended into the feeding channel c under the horizontal driving of the outer end, and the size of the feeding channel c is adjusted, thereby adjusting the amount of ground fertilizer transported by the feeder 10 in the storage bin 33 to adapt to the water flow of the water outlet pile 1 or the water pump, so as to avoid the disadvantages of insufficient fertilizer concentration in the liquid fertilizer resulting in low fertilizer absorption by the fruit trees; or excessive fertilizer absorption resulting from excessive concentration.

[0035] like Figure 3 As shown, a liquid fertilizer valve 16 is also provided on the side of the water flow power chamber 31 close to the water inlet pipe 4. When commercial liquid fertilizer is used, a pipeline is directly connected to the liquid fertilizer valve 16, and the commercial liquid fertilizer is directly input into the water flow power chamber 31. Under the action of the water source, it directly flows into the water outlet pipe 5. The commercial liquid fertilizer is not directly mixed with water through grinding and then input into the infiltration bag 12 described later for infiltration irrigation.

[0036] After the fertilizer is ground in real time by the grinding and dissolving device, and driven and dissolved by water, the present application also provides an infiltration irrigation and weeding mechanism, which is used to guide the fertilizer flowing through the average amount to each fruit tree 14 for infiltration irrigation. The specific structure of the infiltration irrigation and weeding mechanism is as follows: Figure 1 , 6 As shown, it includes an infiltration bag 12 which is laid on one side of the fruit tree 14 along the planting direction of the fruit tree 14 and one end of which is connected to the processing bin 3, and an infiltration hole 12a is opened on the infiltration bag 12 at a position opposite to each fruit tree 14. The ground fertilizer is fully dissolved after mixing and flowing through the infiltration bag 12 driven by water flow. When the water and fertilizer flow to the infiltration hole 12a, the water and fertilizer flow out through the infiltration hole 12a to achieve infiltration irrigation of each fruit tree 14. Compared with the current water-fertilizer integrated sprinkler irrigation method, it can effectively increase the fertilizer absorption of the fruit tree 14.

[0037] On the basis of the above-mentioned water and fertilizer infiltration irrigation, in order to remove weeds in the orchard and solve the problem of weeds blocking the infiltration holes 12a, the infiltration irrigation and weeding mechanism of the present application plays a fertilizing role during irrigation, and usually blocks sunlight, limits the growth of weeds outside the root area of ​​the fruit tree 14, and achieves the weeding function. The restriction of weed growth can prevent the weeds from growing too vigorously and blocking the infiltration holes 12a, and at the same time limit the growth of weeds, which can effectively solve the planting cost problem of frequent and multiple weeding by manual labor.

[0038] like Figure 1 , 6 As shown, the infiltration irrigation and weeding mechanism also includes a weeding bag 13 for covering the area outside the root of the fruit tree 14, which forms a certain coverage width for weeds in the middle of the infiltration irrigation bag 12. The weeding bag 13 covers the area outside the root of the fruit tree 14, that is, isolates the photosynthesis of the weeds, and suppresses the growth of the weeds through the weeding bag 13, thereby limiting the growth of the weeds, that is, solving the problem of easy obstruction of the infiltration irrigation hole 12a caused by vigorous weed growth, and solving the problem of frequent manual weeding and the high planting cost.

[0039] Limiting the growth of weeds can ensure the moisture of the land while retaining the grass roots, so that the roots of fruit trees can maintain a long-term water supply, reduce the evaporation of water on the surface, and effectively reduce the amount of irrigation water during high-temperature irrigation, saving water resources and irrigation costs.

[0040] In the process of limiting the growth of weeds by using the weed removal bag 13, it is inevitable that the growth of the root system of the fruit tree 14 will also have a certain growth impact. Therefore, in order to solve this problem, Figure 7 As shown, the width of the weeding bag 13 is not less than half of the width between adjacent rows of fruit trees 14. In the present application, the width of the weeding bag 13 is preferably slightly larger than half of the width between adjacent rows of fruit trees 14. In the actual operation process, the position of the weeding bag 13 is translated at intervals of a certain period, that is, as shown in FIG. Figure 7As shown, in the first cycle, the weed bag 13 is close to the fruit trees 14 in the left row to block the growth of weeds on this side; the root system of the fruit tree 14 on the right side is in the leaking photosynthesis contact, so that the fruit tree 14 and the root system of the fruit tree can grow normally; when the weeds in the right leaking area grow vigorously, the weed bag 13 is translated to the right side to block the weeds, restricting their photosynthesis and growth, while the root system of the fruit tree 14 on the left side is in the leaking photosynthesis contact, so that the root system of the fruit tree 14 on the left side can grow normally; the sequential operation mode can ensure the normal growth of the root system of the fruit tree 14 while avoiding the growth of weeds, and realize the effect of no-tillage and fertilization without affecting the growth of the fruit tree 14 and the fruit. The weed bag 13 is regularly shifted within the row spacing of fruit trees during the weed growth period to achieve the effect of exchanging and blocking sunlight and limiting the growth of weeds. It will effectively save labor costs, solve the damage to the root system caused by current mechanical farming, as well as the problems of large irrigation volume, high investment cost of water-fertilizer integration, low efficiency, and easy clogging of sprinkler irrigation. It can be widely promoted and applied in the planting of fruit trees 14.

[0041] In order to further optimize the number of components of the no-tillage water-fertilizer weeding system of this application and improve the structural integrity, such as Figure 7 As shown, the present application integrates the infiltration bag 12 and the weeding bag 13 into one, that is, a wider infiltration bag 12 that can cover half of the adjacent planting rows is used, and its side is still provided with an infiltration hole 12a for infiltration irrigation of water and fertilizer, while its overall width is used to limit the growth of weeds, that is, for weeding, so that the infiltration bag 12 and the weeding bag 13 are integrated into a wider infiltration bag 12 for infiltration and weeding, which can effectively save the number of components of the system and improve the integrity of the structure.

[0042] After the water and fertilizer are passed into the wider infiltration bag 12, the side infiltration holes 12a need to have a certain infiltration pressure, so the water and fertilizer need to have a certain expansion and pressure on the infiltration bag 12, resulting in a large amount of water and fertilizer gathering in the infiltration bag 12. After the later infiltration is completed, a large amount of water and fertilizer still remains in the infiltration bag 12, which easily causes the problem of excessive single infiltration fertilizer amount. Therefore, in order to solve this problem, Figure 7 As shown, the middle position of the infiltration irrigation bag 12 is preferably sutured and sealed to form a water and fertilizer circulation space with a smaller inner diameter on both sides thereof, thereby solving the problem of excessive filling of water and fertilizer in the infiltration irrigation bag 12 and affecting the overall fertilizer infiltration amount.

[0043] To further promote the photosynthetic growth of the fruit trees 14, the upper surface of the infiltration bag 12 is preferably provided with a reflective coating to reflect sunlight onto the fruits and leaves, thereby improving the photosynthetic efficiency of the orchard; and the bottom surface of the infiltration bag 12 may preferably be provided with a black coating to achieve a moisturizing effect on the surface and limit the photosynthesis of the covered weeds.

[0044] In order to avoid the weed control period during weed covering in open fields, and to prevent the movement of the irrigation bag 12 and the weed control bag 13 due to the wind in the wilderness, thereby affecting the weed control effect, preferably, nails (not shown in the figure) are evenly arranged on the bottom surface of the weed control bag 13. During the laying process, the nails are inserted into the ground, which can effectively prevent the wind from causing the weed control bag 13 to move and affect the weed control effect.

[0045] Based on the above-mentioned no-tillage water-fertilizer weeding system, the present application also provides an integrated orchard no-tillage water-fertilizer weeding method, with a kiwifruit orchard (such as Figure 8 As shown in the figure, the following steps are included: S1, using the assembly head 2 to be sealed and connected with the water outlet pile 1 and the power pump body, the specific implementation includes: In a planting area with a water outlet pile 1, the assembly head 2 can be directly assembled and connected to the water outlet pile 1 to quickly obtain water; For traditional canal irrigation planting areas where water outlet piles 1 are not arranged, a water pump can be selected to access the canal to obtain water, and the assembly head 2 of the present application can be connected to the water pump port to quickly obtain water. After the assembly head 2 is connected to the water outlet pile 1 or the water pump, water can be quickly obtained for fertilization and irrigation operations. Compared with the current water-fertilizer integrated system, it can significantly reduce the investment of growers, achieve low-cost equipment for growers, reduce labor and facilitate operation and implementation.

[0046] S2. Lay the irrigation bag 12 on one side of the fruit tree 14 along the planting direction of the fruit tree 14 and ensure that the irrigation hole 12a is opposite to each fruit tree 14.

[0047] S3, adding fertilizer to the processing bin 3 for processing, while connecting the water source to the processing bin 3 through the assembly head 2, and driving the ground fertilizer to enter the infiltration bag 12 through the infiltration hole 12a to infiltrate the roots of each fruit tree 14, the specific operation is: Fertilizer is added to the processing bin 3 and ground by the grinding and dissolving device. The size of the ground particles is smaller than the aperture of the later-described infiltration and irrigation hole 12a. After the water source is obtained through the assembly head 2 and enters the processing bin 3, the ground fertilizer is further dissolved. The ground fertilizer is output from the other side of the processing bin 3 under the drive of the water source, and flows through the later-described infiltration and irrigation bag 12 to achieve infiltration and irrigation of the corresponding fruit trees 14 through multiple infiltration and irrigation holes 12a. At the same time, the grinding speed is adjusted according to the flow rate of the connected water source, so that the water source flow rate matches the amount of fertilizer driven and dissolved, thereby effectively solving the problem of dissolution saturation that is very easy to occur during static dissolution in the dissolution tank, and the problem of blockage of the sprinkler port caused by incomplete dissolution.

[0048] The ground fertilizer is driven by water flow and is fully dissolved after mixing and flowing through the infiltration bag 12. When the water and fertilizer flow to the infiltration hole 12a, the water and fertilizer flow out through the infiltration hole 12a to achieve infiltration irrigation of each fruit tree 14. Compared with the current integrated water and fertilizer sprinkler irrigation method, it can effectively increase the fertilizer absorption of the fruit trees 14.

[0049] S4, laying the weed bag 13 parallel to the infiltration bag 12 outside the root area of ​​the fruit tree 14 to control weeds. The specific operation process is: the weed bag 13 covers the area outside the root of the fruit tree 14, that is, it isolates the photosynthesis of weeds, and at the same time suppresses the growth of weeds through the weed bag 13 to achieve the restriction of weed growth, that is, solves the problem of blocking the infiltration hole 12a caused by vigorous weed growth, and solves the problem of large planting costs caused by frequent manual weeding.

[0050] In the process of limiting the growth of weeds by the weeding bag 13, it is inevitable that the growth of the root system of the fruit tree 14 will also be affected to a certain extent. Therefore, the width of the weeding bag 13 selected in this application is not less than half of the width between adjacent rows of fruit trees 14. In this application, the width of the weeding bag 13 is preferably slightly larger than half of the width between adjacent rows of fruit trees 14. In the actual operation process, the position of the weeding bag 13 is translated at regular intervals, that is, Figure 7 As shown, in the first cycle, the weeding bag 13 (because the present application combines the weeding bag 13 with the infiltration bag 12, that is, the infiltration bag 12 is translated, and preferably as shown in Figure 1 As shown, a plurality of assembly ports 51 assembled with the ports of the infiltration bag 12 are provided on the outlet pipe 5, which are used to connect with the bag ports of the infiltration bag 12 after translation, and the unconnected assembly ports 51 can be blocked with plugs) close to the fruit trees 14 in the left row to block the growth of weeds on this side; while the root system of the fruit tree 14 on the right side is in photosynthesis contact with the leakage, so that the fruit tree 14 and the root system of the fruit tree can grow normally; when the weeds in the right leakage area grow vigorously, the weed control bag 13 is translated to the right to block the weeds, restricting their photosynthesis and growth, and The root system of the fruit tree 14 on the left is in leaky photosynthesis contact, so that the root system of the fruit tree 14 on the left and the fruit trees can grow normally; the sequential operation method can ensure the normal growth of the root system of the fruit tree 14 while avoiding the growth of weeds, and realize the effect of no-tillage and fertilization without affecting the growth of the fruit tree 14 and the fruit. It will effectively save labor costs, solve the current damage to the root system caused by mechanical tillage, as well as the problems of large irrigation volume, high investment cost of water-fertilizer integration, low efficiency, easy blockage of sprinkler irrigation, etc. It can be widely promoted and applied in fruit tree planting.

[0051] Based on the above-mentioned comprehensive description of the integrated orchard no-tillage water-fertilizer and weeding system and operation method of the present application, the orchard no-tillage water-fertilizer and weeding system disclosed in the present application can be effectively promoted and applied in orchard fertilization and weeding. The application scope includes kiwi fruit planting orchards (large-scale planting in Mei County, Shaanxi Province), apple planting orchards and other similar fruit tree plantings with planting row spacing, and comprehensive treatment of no-tillage, fertilization and weeding can be carried out.

[0052] The principle of the present invention is: through the no-tillage water-fertilizer and weeding system provided by the present application, the implementation of the system can achieve a one-time operation and realize the comprehensive effects of no-tillage, fertilization and weeding, and completely and comprehensively solves the fertilization method of the prior art that requires repeated mechanical rotary tillage, furrow application or hole application to damage the root system when applying large amounts of chemical fertilizers, and the existing tank water-fertilizer integrated facilities have extremely high investment costs, and the dissolution saturation is difficult to grasp, and the sprinkler ports are often blocked by weeds without weeding. There are also many problems, such as high planting costs due to frequent manual weeding, large evaporation after weeding, and increased irrigation water costs. The no-tillage water-fertilizer and weeding system has the characteristics of low cost, high efficiency, and saving a lot of planting investment costs. It has a great upgrading effect on the existing fruit tree agricultural production and is worthy of wide promotion and application.

[0053] The above shows and describes the basic principle, main features and advantages of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are all within the scope of the present invention claimed for protection.
