[0014] By means of the above technical solutions, the present invention provides a basal fertilizer application device for the cultivation of Idesia polycarpa, which at least has the following beneficial effects: 1. For the basal fertilizer application device for the cultivation of Idesia polycarpa, by setting a material control mechanism, the addition amount of basal fertilizer can be adjusted according to the slope of the planting position. In areas with a slope > 20°, the basal fertilizer (such as a combination of organic fertilizer and slow-release fertilizer) is increased by 15% - 25% to compensate for the loss of soil and water erosion and ensure that the roots (the main root of Idesia polycarpa is 1 - 1.5 meters deep) absorb sufficient nutrients. In areas with a slope < 10°, the chemical fertilizer dosage is reduced by 10% - 15% to avoid fertilizer damage caused by strong water retention ability (Idesia polycarpa is tolerant to barrenness, but excessive nitrogen fertilizer is prone to cause excessive growth).

[0015] 2. For the basal fertilizer application device for the cultivation of Idesia polycarpa, by setting a pushing mechanism 300, the corresponding amount of soil can be backfilled according to the added amount of basal fertilizer. The backfill soil (volume ratio) is matched at 1:3 - 1:5 according to the basal fertilizer amount (such as 10 - 30 kg / plant of organic fertilizer) to form a fertilizer sandwich layer (20 - 40 cm from the ground surface), which not only avoids root burning but also ensures rapid absorption by the roots.

[0016] 3. The base fertilizer application device for Idesia polycarpa planting can also adjust the feeding amount according to the slope of the downhill, convert the tilt angle (slope) of the vehicle body into the displacement amount of the sealing block, and without external sensors or electronic control systems, dynamically adjust the fertilization amount according to the slope, avoiding the problems of excessive application (easy to lose) on steep slopes or insufficient application (affecting growth) on gentle slopes caused by traditional fixed fertilization, and making the fertilizer amount accurately match the root distribution of Idesia polycarpa and the soil fertilizer retention ability.

[0017] 4. The base fertilizer application device for Idesia polycarpa planting can adjust the addition amount of fertilizer according to the slope size both uphill and downhill. When going uphill, the first rack works (meshing above), and when going downhill, the second rack works (meshing below), forming a two-way slope adaptability, covering a slope range of 15° to 45°, and further improving the quality of the added fertilizer.

[0018] 5. The base fertilizer application device for Idesia polycarpa planting can realize linkage operation, without the need to add sensors to separately sense the terrain difference, further improving the quality of the backfill soil. The backfill soil amount and the fertilization amount are dynamically balanced, the soil compactness of the planting pit can be maintained, and the problems of soil compaction caused by excessive backfill or fertilizer leakage and moisture leakage caused by insufficient backfill can be reduced, enhancing the soil water and fertilizer retention ability.

[0019] 6. The base fertilizer application device for Idesia polycarpa planting drives the transmission shaft to rotate forward and backward by the motor. The transmission shaft drives the material guiding box to swing, and the fertilizer will be evenly added to different positions of the pit, forming a parabolic trajectory with a dynamic balance of inclination angle in the pit, avoiding local salt concentration overload of the roots and reducing the incidence of root burning.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The following describes some embodiments of the present invention with reference to the accompanying drawings, which provides a basal fertilizer application device for Idesia polycarpa planting.

[0024] Embodiment 1 In planting environments with different slopes such as mountains, the distribution and loss of fertilizers under different slopes vary significantly. Fertilizers are easily washed away by rain or runoff on steep slopes. If the feeding amount for flat or gentle slopes is used for feeding, it will not only cause waste of fertilizers, but also may lead to soil and water pollution. To solve the above problems, combined with Figures 1 - 4As shown in the figure, the base fertilizer application device for the cultivation of Idesia polycarpa provided by the present invention includes a vehicle body 100, a material bin 101 is fixedly connected to the vehicle body 100, and a material control mechanism 200 for controlling the feeding amount is installed at the material bin 101, which can adjust the addition amount of the base fertilizer according to the slope of the planting position. For the area with a slope > 20°, the base fertilizer (such as a combination of organic fertilizer and slow-release fertilizer) is increased by 15%-25% to compensate for the loss of soil and water erosion and ensure that the roots (the main root of Idesia polycarpa is 1-1.5 meters deep) absorb sufficient nutrients. For the area with a slope < 10°, the amount of chemical fertilizer is reduced by 10%-15% to avoid fertilizer damage caused by strong water retention ability (Idesia polycarpa is tolerant of barrenness, but excessive nitrogen fertilizer is prone to cause excessive growth). A pushing mechanism 300 for filling soil is provided on the vehicle body 100, which can backfill the corresponding amount of soil according to the added amount of the base fertilizer. The backfill soil (volume ratio) is matched at 1:3-1:5 according to the base fertilizer amount (such as 10-30 kg / plant of organic fertilizer) to form a fertilizer sandwich layer (20-40 cm from the ground surface), which not only avoids burning the roots but also ensures rapid absorption by the roots; Since the existing equipment cannot adjust the blanking method according to the tilting state of the vehicle body 100, directly blanking when the vehicle is tilted will cause the fertilizer to accumulate on one side of the pit, resulting in uneven fertilizer distribution. This will lead to a large difference in the nutrient concentration around the plant roots. Some roots may be damaged due to excessive fertilizer concentration, while some roots will grow poorly due to lack of nutrients, affecting the overall growth status and yield of the plants. To solve the above problems, a housing 201 is installed on the vehicle body 100. A slide rail 202 is fixedly connected inside the housing 201. A rolling ball 203 is slidably connected inside the slide rail 202. Springs 204 are fixedly connected to both side walls inside the slide rail 202. An arc-shaped block 205 is installed on the spring 204. Connecting bars 206 that are slidably connected to the slide rail 202 are fixedly connected to the two arc-shaped blocks 205 respectively. A rotating shaft 220 is rotatably installed on one side of the housing 201 away from the material bin 101. A winding roller 209 is fixedly sleeved on the rotating shaft 220. The material control mechanism 200 includes a sealing block 212 that is slidably connected to the discharge port of the material bin 101,A transmission rope 211 for pulling the sealing block 212 to move is wound around the rewinding roller 209. A first spur gear 208 is sleeved on the rotating shaft 220. The first spur gear 208 and the rewinding roller 209 are arranged in a staggered manner. The rewinding roller 209 is close to one side of the sealing block 212. On two connecting bars 206, a first rack 207 and a second rack 210 that are meshed with the first spur gear 208 in a staggered manner are respectively provided. An L-shaped bar 214 is fixedly connected to the sealing block 212. An electric push rod 213 for pushing the sealing block 212 to reset is installed on the silo 101. When the vehicle body 100 travels at positions with different slopes, the vehicle body 100 will be in different degrees of inclined states. When going uphill, the first rack 207 above the position meshes with the first spur gear 208, and the second rack 210 below does not mesh with the first spur gear 208. Due to the inclined state of the vehicle body 100, when reaching the pothole position, the free end of the electric push rod 213 contracts and no longer generates a thrust on the sealing block 212 on the L-shaped bar 214. The sealing block 212 can be moved away from the discharge port. At the same time, the rolling ball 203 will roll to one side. Due to the arrangement of the spring 204, the rolling ball 203 will generate different degrees of thrust on the arc-shaped plate according to the inclination degree, that is, the slope size, so that the connecting bar 206 on the arc-shaped plate drives the first rack 207 to move. The movement of the first rack 207 will drive the first spur gear 208 to rotate. The rotation of the first spur gear 208 will drive the rotating shaft 220 to rotate. The rewinding roller 209 rotates along with the rotating shaft 220. The rotation of the rewinding roller 209 will wind the transmission rope 211. The transmission rope 211 pulls the sealing block 212 to move, and can adjust the moving position of the sealing block 212 according to the slope size, change the size of the discharge port, and thus can adjust the discharge amount according to the slope size. The more the sealing block 212 moves, the more the discharge amount is, and vice versa, the less. When going downhill, the second rack 210 below the position meshes with the first spur gear 208, and the first rack 207 above does not mesh with the first spur gear 208. According to the same working principle above, the feeding amount can also be adjusted according to the slope size of going downhill, convert the inclination angle (slope) of the vehicle body 100 into the displacement amount of the sealing block 212, without an external sensor or an electronic control system, dynamically adjust the fertilization amount according to the slope, avoid the problems of excessive amount on steep slopes (easy to lose) or insufficient amount on gentle slopes (affecting growth) caused by traditional fixed fertilization, and make the fertilizer amount match the root distribution of Idesia polycarpa and the soil fertilizer retention ability accurately.,

[0025] Idesia polycarpa is mostly planted in complex terrains such as terraced fields and ridge cultivation. It can adjust bidirectionally to avoid "lack of fertilizer uphill and fertilizer damage downhill". As shown in the experiment in Zhaotong, Yunnan, the fertilizer loss in the downhill area was reduced by 62%. To solve the above problems, frames 216 are fixedly connected to both connecting bars 206. A screw rod 215 is rotatably installed inside the frame 216. The two screw rods 215 are respectively threadedly connected to the first rack 207 and the second rack 210, and the first rack 207 and the second rack 210 are respectively slidably connected to the frame 216. According to the terrain difference, when going uphill and downhill, the staff rotates the corresponding screw rod 215 respectively. The screw rod 215 will drive the corresponding first rack 207 and second rack 210 to move. Thus, the first rack 207 and the second rack 210 will intersect and mesh with the first spur gear 208. The amount of fertilizer added can be adjusted according to the slope size both uphill and downhill. When going uphill, the first rack 207 works (meshing above), and when going downhill, the second rack 210 works (meshing below), forming a bidirectional slope adaptability, covering a slope range of 15° to 45°, and further improving the quality of added fertilizer.

[0026] According to the embodiment, after adding fertilizer, the free end of the first electric push rod 213 extends to push the sealing block 212 on the L-shaped bar 214 to reset. Repeating the above steps, when reaching the next pit, fertilizer can continue to be added.

[0027] Embodiment 2: In mountain environments with different slopes, the distribution and loss of fertilizers show significant differences: on steep slopes (>25°), due to the fast runoff speed (0.5 - 1.2 m / s), the fertilizer loss rate is as high as 35% - 50%, and gravity causes lack of fertilizer uphill (root zone concentration < 40% of the design value) and fertilizer damage downhill (EC value exceeds the threshold by 60%); on gentle slopes (15° - 25°), the runoff speed is 0.2 - 0.5 m / s, and the loss rate is 15% - 25%. There is an easy occurrence of a banded distribution of lack of phosphorus uphill (<80 mg / kg) and excessive nitrogen downhill (>150 mg / kg). To solve the above problems, combined with Figure 5 and Figure 6 As shown, on the basis of Embodiment 1, a limit frame 302 is fixedly connected to the bottom wall of the vehicle body 100. A connecting shaft 307 is rotatably installed on the limit frame 302. A lead screw 303 is fixedly connected to the bottom of the connecting shaft 307. A guide plate 301 that is slidably connected to the limit frame 302 is threadedly connected to the lead screw 303. Since the soil will be piled up on one side when digging pits, according to the amount of base fertilizer added, the lead screw 303 rotates to drive the guide plate 301 to move. When the guide plate 301 moves downward, the subsequent movement of the vehicle body 100 will drive the guide plate 301 to move. The greater the downward movement distance of the guide plate 301, the more fertilizer is added, and vice versa. Thus, the corresponding amount of soil can be pushed backfilled into the pit according to the amount of base fertilizer, realizing the quantitative ratio of base fertilizer and backfill soil, ensuring that the fertilizer is evenly wrapped by the soil, avoiding volatilization and leaching losses caused by exposed fertilizer, and improving the fertilizer utilization rate.

[0028] The sensor is vulnerable to dust and mud pollution in the mountain environment, resulting in a decline in reliability. There is a delay in signal acquisition and processing, and manual calibration is required regularly. To solve the above problems, a second spur gear 304 is fixedly connected to the top of the connecting shaft 307. A third rack 305 that meshes with the second spur gear 304 is provided on the vehicle body 100. The third rack 305 is slidably connected to the vehicle body 100 through a second chute 310. A push rod 308 is fixedly connected to the side of the sealing block 212 close to the third rack 305, which is used to push the third rack 305 to move. An electric push rod two 306 for pushing the third rack 305 to reset is also provided on the vehicle body 100. When the sealing block 212 moves, it will also push the third rack 305 to move through the push rod 308. When the third rack 305 moves, it drives the lead screw 303 on the connecting shaft 307 to rotate through the second spur gear 304. The rotation of the lead screw 303 will drive the material guide plate 301 to move. The descending distance of the material guide plate 301 can be adjusted according to different slope sizes, and the corresponding amount of soil can be backfilled according to the fertilizer addition amount. Moreover, it can realize linkage operation, without the need to add a sensor to separately sense the terrain difference, further improving the quality of the backfilled soil. The dynamic balance between the backfilled soil amount and the fertilization amount can maintain the soil compactness of the planting pit, reduce the problems of soil hardening caused by excessive backfilling or fertilizer leakage and soil moisture leakage caused by insufficient backfilling, and enhance the soil's water and fertilizer retention capacity.

[0029] Furthermore, a protective cover 309 is fixedly connected to the vehicle body 100. The electric push rod two 306 is installed on the protective cover 309. The third rack 305 and the second spur gear 304 are located inside the protective cover 309. The push rod 308 penetrates the protective cover 309 and is slidably connected to the protective cover 309.

[0030] According to the embodiment, an appropriate soil covering thickness (matched with the base fertilizer amount) can prevent the root system from being burned by excessive fertilizer concentration ("burning roots"), and at the same time keep the soil loose and breathable, providing a stable microenvironment for the root development of Idesia polycarpa.

[0031] Embodiment Three: Since the vehicle is in an inclined state, when directly discharging materials, the fertilizer will accumulate on one side of the pit hole, and the fertilizer distribution is seriously uneven, resulting in local overloading of the fertilizer concentration in the plant root system and causing the phenomenon of root burning and root rot. Combining Figure 5 and Figure 7As shown in the figure, on the basis of the first embodiment, a material guiding hopper 102 is fixedly connected to the vehicle body 100 below the discharge port of the material bin 101. A motor 103 is also fixedly installed on the bottom wall of the vehicle body 100. The output end of the motor 103 is fixedly connected to a transmission shaft 104. A material guiding box 105 is fixedly connected to the transmission shaft 104. A soft edge 106 is bonded between the discharge port of the material guiding box 105 and the material guiding hopper 102. Through the soft edge 106, a sealed channel is formed between the discharge port of the material guiding box 105 and the material guiding hopper 102. The added fertilizer will first enter the material guiding hopper 102. The motor 103 drives the transmission shaft 104 to rotate forward and backward. The transmission shaft 104 drives the material guiding box 105 to swing, and the fertilizer will be evenly added to different positions of the pit, so that the fertilizer forms a parabolic trajectory with a dynamic balance of inclination angle in the pit, avoiding local salt concentration overload of the root system and reducing the incidence of root burning.

[0032] According to the embodiment, when directly discharging materials during vehicle tilting, the fertilizer is easily accumulated on one side of the pit, resulting in extremely uneven distribution of the fertilizer. While the swinging discharge of the material guiding box 105 can make the fertilizer be more evenly dispersed in the pit, prevent the local fertilizer concentration from being too high, avoid the phenomenon of "root burning" to the plant roots, and improve the absorption efficiency of the plant roots to the fertilizer.

[0033] Embodiment Four: Combined with Figures 1 - 3 As shown in the figure, on the basis of the first embodiment, a U-shaped frame 217 is fixedly connected to the discharge port of the material bin 101. The sealing block 212 is slidably connected to the U-shaped frame 217 through a chute one 219. The L-shaped strip 214 penetrates through the U-shaped frame 217 and is slidably connected to the U-shaped frame 217.

[0034] Specifically, the L-shaped strip 214 and the electric push rod one 213 are in the same plane. A protective pad is fixedly connected to the end of the electric push rod one 213, which can protect the components.

[0035] Furthermore, the end of the screw 215 extends to the outside of the frame body 216 and is fixedly connected to a rotating block 218. The staff rotates the rotating block 218 to facilitate the rotation of the screw 215.

[0036] An inspection door is provided on the outer shell 201, and a handle is fixedly connected to the inspection door. Opening the inspection door facilitates the inspection of the components inside the outer shell 201.

[0037] As can be seen from the above embodiments, the staff pre-adjust the corresponding screw 215 according to the terrain. When the vehicle body 100 inclines uphill or downhill, the rolling ball 203 rolls downward under gravity to squeeze the spring 204, and pushes the connecting bar 206 through the arc-shaped block 205. When going uphill, the upper rack one 207 meshes with the spur gear one 208, and the movement of the rack drives the rotation of the rotating shaft 220. The winding roller 209 winds the transmission rope 211 to pull the sealing block 212 to open the discharge port. When going downhill, the lower rack two 210 meshes, and the opening degree of the sealing block 212 is adjusted in the reverse direction. After reaching the pit position, the electric push rod one 213 contracts to release the sealing block 212, and the fertilizer falls through the discharge port with accurate opening degree, converting the slope into the displacement of the sealing block 212 to achieve two-way dynamic material control for uphill and downhill. After the operation, the electric push rod resets the sealing block 212, and the spring 204 eliminates the transmission clearance, completing the full mechanical process of "pre-adjusting the screw 215 → slope induction → rack switching → sealing material control → reset cycle". Without sensors, the fertilizer amount can be automatically adjusted according to the slope of 0° to 45°, solving the problems of lack of fertilizer uphill and fertilizer damage downhill, and achieving precise fertilization for all terrains in the mountains.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
