[0002] Weeds are extremely harmful to agricultural production, causing a 10% reduction in global crop yields each year. However, after spraying herbicides, the weeds that have already grown can only be eliminated for a short time. After a period of time, the weeds will pop up again, and there will be even more weeds next year. Herbicides are sprayed every year, but the weeds cannot be completely eliminated every year. The root cause is that there are more than 50,000 weed seeds per square meter in the 30-centimeter tillage layer. Due to differences in weed depth, dormancy period, etc., weed seeds germinate and emerge from the ground every year, and are always difficult to eliminate. Therefore, how to effectively eradicate weeds and reduce the annual use of herbicides and the planting costs of growers in the later period is a technical problem that urgently needs to be solved in the existing agricultural field.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Compared with the traditional weed control method, the present invention does not simply increase the amount of herbicide used, but applies the herbicide to the field or other cultivation facilities in advance. Under the action of the solvent, the herbicide penetrates into the ground and contacts the weed seeds, thereby breaking the dormancy of the weed seeds, inducing weed germination, promoting weed growth, and making the weed seeds underground germinate in a concentrated manner, and then spraying the herbicide for unified removal. Such operation greatly reduces the number of weed seeds in the soil in the next year, interrupts the growth and reproduction of weeds, and after repeated multiple times, the number of weeds becomes even rarer. There is basically no need to spray the herbicide again for many years thereafter, so that the weeds are completely removed. In the long run, the amount of herbicide used is greatly reduced, the workload caused by weed removal is reduced, and the planting cost is effectively reduced;

[0022] 2. When applying the weed attractant, the power assembly is used to drive the slide seats on both sides of the frame to slide downward, so that the liquid filling tube and the multiple weed attractant drip tubes thereon move downward until the cone rod is inserted into the ground. At this time, the telescopic rod is in a downwardly extended state, driving the upper plug to open the top of the liquid filling head. At the same time, under the action of the steering assembly, the multiple positioning rods are driven to slide horizontally, so that they penetrate the side wall of the liquid filling head and are movably connected with the weed attractant drip tube, thereby achieving the fixation of the weed attractant drip tube and the liquid filling head. When the two are fixed, the convex block at the bottom of the liquid filling head contacts the lower plug and drives it to slide downward to compress the return spring, so that the top of the weed attractant drip tube is opened, so that the weed attractant and solvent in the weed attractant storage tank can pass through the liquid filling tube and the multiple liquid filling heads thereon, and automatically enter the weed attractant drip tubes at various positions, thereby achieving automatic liquid filling of multiple weed attractant drip tubes. When a group of weed attractant drip tubes are inserted into the ground, the telescopic rod is retracted upward, so that the upper plug slides upward to block the liquid filling head. At the same time, under the action of the steering assembly, the multiple positioning rods slide horizontally and reset, releasing In addition to limiting the position of the weed attractant dripper, the liquid loading head can be separated from the weed attractant dripper. After that, the slide seats on both sides slide upward under the drive of the power assembly, driving the liquid loading tube and the multiple liquid loading heads thereon to rise and then separate from the weed attractant dripper, leaving a group of weed attractant drippers in the field. After the liquid loading head is separated from the weed attractant dripper, the lower plug loses the squeezing of the convex block and slides upward under the action of the reset spring to reset and seal the top of the weed attractant dripper. After the outside air enters through the air inlet on the lower plug, the weed attractant and solvent inside are vented. The agent can be gradually discharged from the dripping hole of the cone rod, so that the herb attractant gradually penetrates into the ground, and then the frame moves forward under the action of the walking wheel, and at the same time, the liquid loading pipe rotates to rotate another set of herb attractant dripping tubes to the vertical direction, and the above steps are repeated so that all the herb attractant dripping tubes are inserted into the ground and distributed at various positions in the field, so that the herb attractant can fully contact the weed seeds at various positions underground in the field, avoiding the volatilization of the herb attractant, improving the inducing effect on underground weed seeds, and reducing the residual amount of weed seeds;

[0023] 3. Before planting crop seeds, mix herbicide-resistant agents with crop seeds to form a seed coating film on the outside of the crop seeds. The seed coating film can improve the tolerance of crop seeds to one or several corresponding herbicides. When spraying herbicides on weeds that germinate and grow at the same time, the seed coating film is used to protect the crop seeds, which greatly reduces the harm of herbicides to crops after germination, improves the weed control effect, and effectively protects the crops, ensuring the crop yield.

[0033] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0034] The present invention discloses a method and device for weeding using plant attractants, wherein the method for weeding using plant attractants comprises the following steps:

[0035] S1. Coating crop seeds, mixing herbicide-resistant crops with crop seeds, forming a seed coating film on the outside of the crop seeds, improving the tolerance of crop seeds to one or more corresponding herbicides, and the herbicide-resistant components can be adaptively selected according to the corresponding herbicide types. The components of the seed coating film can be gradually released during the germination process of the crop seeds in the later stage, so that when the herbicide is sprayed after the crop germinates and grows, it can effectively resist the damage caused by the herbicide to the crop, and protect the crop in advance. Different from the method of remedying the damage to the crop after it is damaged, the protection effect of the crop is improved, and the yield of the crop is guaranteed;

[0036] S2. Planting of crop seeds: planting the crop seeds with seed coating film in the field or other cultivation facilities. Planting the crop seeds with seed coating film at the appropriate time and weather conditions. The planting density and other data can be calculated according to the actual planting needs.

[0037] S3, applying a weed attractant, and using an infiltration device to infiltrate the weed attractant into the ground with the aid of a solvent, wherein the solvent is generally water, and the weed attractant is an attractant extracted from plant materials, preferably from corn of the Gramineae family or soybean of the Leguminosae family, and specifically, a natural product of the Karrikins class extracted from plant combustion, which is a plant signal molecule, is used. The weed attractant is mixed with water and then applied, and the weed attractant contacts the weed seeds in the ground to break the dormancy of the weed seeds, induce weed germination, and promote weed growth;

[0038] S4, spraying herbicides. After the weeds grow leaves, one or more herbicides corresponding to the herbicide resistance are sprayed. The type of herbicide is not specifically limited. Phenoxyacetic acid compounds or sulfonylurea compounds commonly used on the market can be used. The amount of herbicide used is based on the premise of killing the weeds without damaging the crops. The number of weeds is greatly increased compared to the number in traditional planting, so it is necessary to spray twice or even more times the amount of herbicides. However, the crops will not be damaged due to the protection of herbicide resistance, so that the concentrated weeds can be quickly and concentratedly removed, avoiding the situation where the herbicide needs to be sprayed every year, greatly improving the convenience of weed removal, and after the weeds are removed, the weed seeds will not be scattered in the field again, and the weed seeds in the soil are also activated and removed, so the number of weeds grown next year will be greatly reduced, making the removal of weeds more thorough;

[0039] S5. Repeat steps S1-S4 in the second year until the weed seeds in the field or other cultivation facilities are exhausted. Thereafter, there is no need to spray herbicides every year to kill and eliminate the weeds. This process generally lasts for two years. After that, the weed seeds in the soil are completely germinated and eliminated, interrupting the growth and reproduction of the weeds, achieving the three-step weed control operation of attracting, tolerating and killing the weeds. There is no need to spray herbicides every year for weed control. In the long run, the amount of herbicides used is greatly reduced, the cost and workload caused by repeated weeding are reduced, and the weeds are completely eliminated.

[0040] Reference Figure 1 and Figure 2 A device for weeding using plant attractants includes a penetration device. Since the herb attractant needs to penetrate into the ground with the assistance of a solvent in order to contact the weed seeds inside the tillage layer, and the traditional spraying method easily causes the herb attractant to volatilize quickly, it is difficult to effectively penetrate the herb attractant to various positions underground, thereby greatly affecting the effect of inducing germination of weed seeds. Therefore, the herb attractant is assisted to penetrate with the help of the penetration device to ensure that the herb attractant is fully and effectively in contact with the weed seeds under the tillage layer. The penetration device includes a frame 1, and the frame 1 is used It is made of metal material and plays a supporting role. The bottom of the frame 1 is rotatably connected to a running wheel 2 through a bearing. The running wheel 2 is used to drive the frame 1 to move. It can be pushed by manpower or driven by a motor or other structure to rotate. The frame 1 is provided with a weed attractant storage tank 3. The weed attractant and the matching solvent are stored in the weed attractant storage tank 3. The weed attractant storage tank 3 is provided with a connected liquid outlet pipe 4. Specifically, a water pump is provided on the weed attractant storage tank 3. The liquid outlet end of the water pump is connected to the liquid outlet pipe 4, so that the weed attractant can be discharged through the liquid outlet pipe 4. The frame 1 is symmetrically provided with a slide seat 5 that slides vertically. Specifically, vertical sliding holes are symmetrically provided on both sides of the frame 1. The slide seat 5 is slidably connected in the sliding hole. A liquid-filling pipe 6 is rotatably connected between the two slide seats 5 through a bearing. Specifically, both ends of the liquid-filling pipe 6 are rotatably connected to the slide seat 5 through a bearing. One end of the liquid-filling pipe 6 is rotatably connected to the liquid outlet pipe 4 through a bearing, and the other end is closed, so that the herb attractant can enter the rotating liquid-filling pipe 6 through the liquid outlet pipe 4. The frame 1 is provided with a power component that drives the slide seat 5 to slide up and down. The force assembly is used to drive the slide 5 and the liquid-filling tube 6 to slide back and forth up and down. The liquid-filling tube 6 is provided with a plurality of interconnected liquid-filling heads 7 in an array. The liquid-filling heads 7 are multiple groups distributed along the axial direction of the liquid-filling tube 6. Each group of liquid-filling heads 7 is multiple and extends along the radial direction of the liquid-filling tube 6. The liquid-filling heads 7 are fixed to the side of the liquid-filling tube 6 by welding or bolts. The corresponding positions of the liquid-filling heads 7 and the liquid-filling tube 6 are connected by through holes. The bottom end of the liquid-filling head 7 is movably connected with a weed attractant dripper 8, which is connected to the bottom end of the liquid-filling head 7 in a detachable manner. Figure 7The bottom of the liquid filling head 7 is provided with a liquid filling hole 9 connected to the weed attractant dripping tube 8. The liquid filling hole 9 runs through the bottom of the liquid filling head 7. After the weed attractant dripping tube 8 is connected to the liquid filling head 7, the weed attractant entering the liquid filling head 7 passes through the liquid filling hole 9 and enters the weed attractant dripping tube 8;

[0041] A telescopic rod 10 is fixed to the top of the liquid filling head 7 by welding or bolts, and specifically, a pneumatic cylinder or electric cylinder structure can be adopted. An upper plug 11 for controlling the opening and closing of the top of the liquid filling head 7 is fixed to the telescopic rod 10 by welding or bolts. When the upper plug 11 moves upward, its side contacts the inner side wall of the top of the liquid filling head 7, so that the top of the liquid filling head 7 can be closed to prevent the herbicide from entering the liquid filling head 7. When it moves downward, its side separates from the side wall of the top of the liquid filling head 7, and the top of the liquid filling head 7 is opened to allow the herbicide to pass through. A plurality of positioning rods 12 that slide in the transverse direction are provided at the bottom of the liquid filling head 7. The positioning rods 12 are slidably connected to the bottom of the liquid filling head 7. After the positioning rods 12 penetrate the side wall of the liquid filling head 7, they are movably connected to the herbicide dropper 8 Such a structure enables the positioning rod 12 to be plugged and connected with the weed attractant drip tube 8 by sliding horizontally, so that the weed attractant drip tube 8 cannot be separated from the liquid filling head 7 in the vertical direction, and the weed attractant drip tube 8 and the liquid filling head 7 are detachably connected. A steering assembly is provided between the telescopic rod 10 and the positioning rod 12, and the steering assembly is used to convert the vertical movement of the telescopic rod 10 into the lateral movement of the positioning rod 12. When the telescopic rod 10 is extended downward, the positioning rod 12 can be driven to slide horizontally under the action of the steering assembly to achieve locking of the connection between the liquid filling head 7 and the weed attractant drip tube 8. Similarly, when the telescopic rod 10 is retracted upward, the lock can be released, so that the liquid filling head 7 can be separated from the weed attractant drip tube 8. A lower plug 13 that moves vertically is provided in the weed attractant drip tube 8. The lower plug 13 is used to control the opening and closing of the top of the weed attractant drip tube 8. Similarly, when the lower plug 13 moves upward, its side surface contacts the inner side wall of the top of the weed attractant drip tube 8 to close the top of the weed attractant drip tube 8. When it moves downward, its side surface separates from the inner side wall of the top of the weed attractant drip tube 8, thereby opening the top of the weed attractant drip tube 8. The lower plug 13 is provided with a penetrating air inlet hole 14. A return spring 15 is provided between the lower plug 13 and the weed attractant drip tube 8. A convex block 16 for driving the lower plug 13 to move is welded or bolted to the bottom of the liquid filling head 7. After the weed attractant drip tube 8 is connected to the liquid filling head 7, the convex block 16 contacts the lower plug 13 and squeezes it to slide downward, compressing the return spring 15, thereby opening the top of the weed attractant drip tube 8. The bottom of the frame 1 is welded or integrally formed with a connected cone rod 17, the interior of the cone rod 17 is a hollow structure, and the interior is connected to the interior of the weed attractant drip tube 8. The cone rod 17 is provided with a plurality of drip holes 18. Such a structure makes it easier for the weed attractant drip tube 8 to be inserted into the ground in the field through the cone rod 17 at the bottom. The weed attractant is gradually discharged from the drip holes 18 on the cone rod 17 and penetrates into the ground, thereby avoiding the volatilization of the weed attractant, so that the weed attractant can more accurately contact the weed seeds deep underground, improve the germination effect of the weed seeds deep underground, and reduce the residual amount of weed seeds. When in use, the power component is used to drive the slide seats 5 on both sides of the frame 1 to slide downward, so that the liquid tube 6 and the plurality of weed attractant drip tubes 8 thereon move downward until the cone rod 17 is inserted into the ground.At this time, the telescopic rod 10 is in a downwardly extended state, driving the upper plug 11 to open the top of the liquid loading head 7. At the same time, under the action of the steering assembly, the multiple positioning rods 12 are driven to slide horizontally, so that they penetrate the side wall of the liquid loading head 7 and are movably connected with the weed attractant dropper 8, thereby achieving the fixation of the weed attractant dropper 8 and the liquid loading head 7. When the two are fixed, the convex block 16 at the bottom of the liquid loading head 7 contacts the lower plug 13 and drives it to slide downward to compress the reset spring 15, so that the top of the weed attractant dropper 8 is opened, thereby making the weed attractant dropper 8 The weed attractant and solvent in the weed attractant storage tank 3 can automatically enter the weed attractant drippers 8 at various positions after passing through the liquid filling pipe 6 and the multiple liquid filling heads 7 thereon, so as to realize the automatic filling of the multiple weed attractant drippers 8. When a group of weed attractant drippers 8 are inserted into the ground, the telescopic rod 10 is retracted upward, so that the upper plug 11 slides upward to block the liquid filling head 7. At the same time, under the action of the steering assembly, the multiple positioning rods 12 slide horizontally and reset, so as to release the limit of the weed attractant dripper 8, so that the liquid filling head 7 can be separated from the weed attractant dripper 8. After that, the slide seats 5 on both sides slide upwards driven by the power assembly, driving the liquid-filling tube 6 and the multiple liquid-filling heads 7 thereon to rise and separate from the weed attractant dripping tube 8, leaving a group of weed attractant dripping tubes 8 in the field. After the liquid-filling heads 7 are separated from the weed attractant dripping tubes 8, the lower plug 13 loses the squeezing of the protrusion 16 and slides upwards under the action of the reset spring 15 to reset and seal the top of the weed attractant dripping tube 8. After the outside air enters through the air inlet 14 on the lower plug 13, the weed attractant and solvent inside can be discharged from the bottom. The drip holes 18 are gradually discharged, so that the herbicide gradually penetrates into the ground. After that, the frame 1 moves forward under the action of the walking wheel 2, and at the same time, the liquid pipe 6 rotates to rotate another set of herbicide drip tubes 8 to the vertical direction. The above steps are repeated so that all the herbicide drip tubes 8 are inserted into the ground and distributed at various positions in the field, so that the herbicide can fully contact the weed seeds at various positions underground in the field, avoiding the volatilization of the herbicide, improving the inducing effect on underground weed seeds, and reducing the residual amount of weed seeds.

[0042] Preferably, a guide column 19 is fixed to the bottom of the liquid filling head 7 by welding or bolts, and a connecting seat 20 is fixed to the movable end of the telescopic rod 10 by welding or bolts, and the connecting seat 20 is slidably connected to the guide column 19, and the steering assembly is arranged between the connecting seat 20 and the positioning rod 12. With such a structure, when the movable end of the telescopic rod 10 performs telescopic movement, the connecting seat 20 of the movable end slides relative to the guide column 19, thereby providing sliding support for the movable end of the telescopic rod 10, avoiding the movable end from being suspended in the air, improving the stability of the up and down sliding movement of the movable end of the telescopic rod 10, and thus being able to better cooperate with the steering assembly, thereby improving the smoothness of the steering cooperation with the positioning rod 12.

[0043] Preferably, refer to Figure 3 and Figure 5The steering assembly includes a plurality of connecting rods 21, the top of the connecting rod 21 is rotatably connected to the side of the connecting seat 20 through a pin or a hinge, and the bottom of the connecting rod 21 is rotatably connected to the positioning rod 12 through a pin or a hinge. When the connecting seat 20 moves up and down, such a structure can drive the ends of the plurality of connecting rods 21 on the side to move up and down, thereby making the positioning rod 12 at the other end of the connecting rod 21 move laterally, realizing the smooth conversion of vertical movement into lateral movement, so that the positioning rods 12 at multiple positions can be smoothly plugged and connected with the herb attractant dropper 8, thereby improving the fixing effect of the connection between the herb attractant dropper 8 and the liquid filling head 7.

[0044] Preferably, a plurality of guide sleeves 22 are fixed to the bottom of the liquid filling head 7 by welding or bolts, and the longitudinal section of the guide sleeve 22 is an inverted U shape. The positioning rod 12 is slidably connected inside the guide sleeve 22. The setting of the guide sleeve 22 can limit the lateral sliding of the positioning rod 12 to prevent the end of the positioning rod 12 from tilting, so that the positioning rod 12 always maintains a lateral state when sliding, making the lateral sliding movement smoother, so that it can be more accurately plugged in with the herb attractant dropper 8, thereby improving the accuracy and firmness of the plug-in cooperation with the herb attractant dropper 8.

[0045] Preferably, the top of the weed attractant dropper 8 is sleeved on the bottom of the liquid filling head 7. Preferably, the top opening size of the weed attractant dropper 8 is adapted to the outer wall size of the bottom of the liquid filling head 7, so that the weed attractant dropper 8 can be smoothly sleeved on the bottom of the liquid filling head 7 along the vertical direction. Thereafter, it is only necessary to plug and match the positioning rod 12 with the weed attractant dropper 8 along the horizontal direction to limit the vertical relative movement of the two, so that the detachable matching of the two is more convenient and firm. A plurality of positioning holes 23 are provided on the side wall at the top of the weed attractant dropper 8. The positioning rod 12 is movably plugged into the positioning hole 23, and the positioning hole 23 extends along the horizontal direction, so that the positioning rod 12 can be smoothly plugged into the positioning hole 23 after sliding horizontally, thereby improving the firmness of the plug-in matching with the weed attractant dropper 8.

[0046] Preferably, a bracket 24 is fixed inside the herb attractant dropper 8 by welding or bolts, a fixed plate 25 is welded or bolted to the top of the bracket 24, and the return spring 15 is arranged between the fixed plate 25 and the lower plug 13. Such a structure utilizes the bracket 24 and the fixed plate 25 to support the bottom of the return spring 15, so that the return spring 15 can be accurately compressed when the lower plug 13 moves downward, thereby improving the accuracy of the subsequent upward return movement of the return spring 15, so that the lower plug 13 can firmly seal the top of the herb attractant dropper 8, effectively preventing the volatilization of the herb attractant.

[0047] Preferably, the tops of the liquid filling head 7 and the weed attractant dropper 8 are both tapered, narrow at the top and wide at the bottom, and the longitudinal sections of the upper plug 11 and the lower plug 13 are both trapezoidal, used in conjunction with the tapered inner wall. With such a structure, the upper plug 11 and the lower plug 13 can fit with the top side wall whose inner diameter gradually decreases when moving upward, thereby more tightly sealing the top of the liquid filling head 7 or the weed attractant dropper 8, and separate from the side wall whose inner diameter gradually increases when moving downward, thereby making the closure of the liquid filling head 7 and the weed attractant dropper 8 tighter, with a simple structure and convenient operation, thereby improving the accuracy of the opening and closing control of the two.

[0048] Preferably, refer to Figure 3 and Figure 6 The drip holes 18 are arranged at the bottom and the side of the cone rod 17, and the drip holes 18 on the side are arranged obliquely. Such a structure allows the herb attractant to vertically penetrate through the drip holes 18 at the bottom and to obliquely penetrate through the inclined drip holes 18 on the side, so that the herb attractant can gradually spread downward and around along the insertion position of the cone rod 17, forming a radial penetration centered on the insertion position of the cone rod 17, thereby improving the penetration effect of the herb attractant and expanding the range of penetration.

[0049] Preferably, refer to Figure 4 The power assembly includes a lifting rod 26, which can be a pneumatic cylinder or an electric cylinder structure. The lifting rod 26 is welded or bolted to the frame 1, and the slide 5 is welded or bolted to the movable end of the lifting rod 26. A rotating motor 27 is welded or bolted to the slide 5 on one side, and mutually meshing gears 28 are welded or bolted to the output shafts of the liquid filling tube 6 and the rotating motor 27. Such a structure can drive the liquid filling tube 6 to rotate under the connection of the meshing gears 28 when the rotating motor 27 is started, so that the rotation control of the liquid filling tube 6 is more convenient and accurate.

[0050] Working principle: Compared with traditional weed control methods, the present invention does not simply increase the amount of herbicides used, but applies herbicides to the field or other cultivation facilities in advance. Under the action of the solvent, the herbicides penetrate into the ground and come into contact with the weed seeds, thereby breaking the dormancy of the weed seeds, inducing weed germination, promoting weed growth, and making the underground weed seeds germinate in a concentrated manner, and then spraying herbicides for unified removal. Such an operation greatly reduces the number of weed seeds in the soil in the following year, interrupting the growth and reproduction of weeds. After repeated repeated attempts, the number of weeds becomes even rarer, and there is basically no need to spray herbicides again for many years thereafter, thereby achieving complete removal of weeds. In the long run, the amount of herbicides used is greatly reduced, and the workload caused by weed cleaning is reduced. The planting cost is effectively reduced; when applying the herbicide, the power assembly is used to drive the slide seats 5 on both sides of the frame 1 to slide downward, so that the liquid-filling tube 6 and the multiple herbicide droppers 8 thereon move downward until the cone rod 17 is inserted into the ground. At this time, the telescopic rod 10 is in a downward extension state, driving the upper plug 11 to open the top of the liquid-filling head 7. At the same time, under the action of the steering assembly, the multiple positioning rods 12 are driven to slide horizontally, so that they penetrate the side wall of the liquid-filling head 7 and then flexibly connect with the herbicide droppers 8, thereby achieving the fixation of the herbicide droppers 8 and the liquid-filling head 7. When the two are fixed, the protrusion 16 at the bottom of the liquid-filling head 7 contacts the lower plug 13 and drives it to slide downward to compress the return spring 15, so that the top of the herbicide dropper 8 is opened, so that the herbicide storage tank 3 is filled with the herbicide. The weed attractant and solvent can pass through the liquid filling tube 6 and the multiple liquid filling heads 7 thereon, and automatically enter the weed attractant drip tubes 8 at various positions, so as to realize the automatic filling of the multiple weed attractant drip tubes 8. When a group of weed attractant drip tubes 8 are inserted into the ground, the telescopic rod 10 contracts upward, so that the upper plug 11 slides upward to block the liquid filling head 7. At the same time, under the action of the steering assembly, the multiple positioning rods 12 slide horizontally and reset, and the limit of the weed attractant drip tube 8 is released, so that the liquid filling head 7 can be separated from the weed attractant drip tube 8. Thereafter, the slide seats 5 on both sides slide upward under the drive of the power assembly, driving the liquid filling tube 6 and the multiple liquid filling heads 7 thereon to rise and separate from the weed attractant drip tube 8, leaving a group of weed attractant drip tubes 8 in the field. After the liquid filling head 7 is separated from the weed attractant drip tube 8, the lower plug 1 After the compression of the protrusion 16 is lost, it slides upward and resets under the action of the reset spring 15 to close the top of the weed attractant drip tube 8. After the outside air enters through the air inlet 14 on the lower plug 13, the internal weed attractant and solvent can be gradually discharged from the drip hole 18 of the cone rod 17, so that the weed attractant gradually penetrates into the ground. After that, the frame 1 moves forward under the action of the walking wheel 2, and at the same time, the liquid pipe 6 rotates to rotate another group of weed attractant drip tubes 8 to the vertical direction. Repeat the above steps so that all the weed attractant drip tubes 8 are inserted into the ground and distributed at various positions in the field, so that the weed attractant can fully contact the weed seeds at various positions underground in the field, avoiding the volatilization of the weed attractant, improving the inducing effect on the underground weed seeds, and reducing the residual amount of weed seeds;Before planting crop seeds, herbicide-resistant agents are mixed with crop seeds to form a seed coating film on the outside of the crop seeds. The seed coating film can improve the tolerance of crop seeds to the corresponding one or several herbicides. When spraying herbicides on weeds that germinate and grow uniformly, the seed coating film is used to protect the crop seeds, greatly reducing the harm of herbicides to crops after germination, improving the weed control effect, and effectively protecting the crops, ensuring the crop yield.
