[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This irrigation and fertilization device for planting lodging-resistant honey plum trees in karst mountainous areas is equipped with a single-tree umbrella-style double-layer protective structure, and integrates a mountain-adaptive base and a drip irrigation and fertilization system. It can achieve wind and rain protection, heat preservation and protection, pressure relief and wind pressure resistance, simultaneous deployment and retraction of the protective film net, and integrated drip irrigation and fertilization operations. It is suitable for karst undulating mountains with shallow soil layers. The specific details are as follows:

[0019] 1. This device integrates the water and fertilizer tank and drip irrigation pipes directly onto the footboard frame. The protective mechanism and water and fertilizer device are integrated into one unit, eliminating the need for separate installation of two sets of equipment. The footboard frame, together with the deflectable and lockable main column, allows adjustment of the main column's vertical posture according to the karst slope terrain. The deep-buried ground nails are adapted to shallow gravelly soil layers, improving the overall lodging resistance. Water and fertilizer from the water and fertilizer tank are directly drip-irrigated to the plum tree basins via the drip irrigation pipes, improving the water and fertilizer utilization efficiency in mountainous areas.

[0020] 2. The double-layer protective structure adopts a composite structure of an upper explosion-proof net and a lower PO light-transmitting film. The explosion-proof net resists the impact of storms, while the light-transmitting film provides rain protection and insulation against day and night temperature differences. Pressure relief holes are opened in the inner ring of the protective structure to release the internal wind pressure of the umbrella in windy weather, reducing the risk of the sealed umbrella bulging and tearing, and reducing the risk of fruit cracking caused by direct rain during the ripening period of the plum. A shrinkage traction module is set up in conjunction with a flexible transmission mechanism to realize the synchronous unfolding and retraction of the explosion-proof net and the light-transmitting film.

[0044] Working principle: When using this irrigation and fertilization device for planting lodging-resistant honey plum trees in karst mountainous areas, first refer to... Figures 1-13 Place the footboard 1 on the karst slope next to the plum tree and anchor it deeply with ground nails. Adjust the main column 2 by rotating it around the bottom convex shaft according to the ground slope. Screw the positioning screw 4 into the corresponding positioning hole 3 to lock the main column 2. Add water and fertilizer solution into the water and fertilizer tank 5 through the connector 7. The liquid inside the water and fertilizer tank 5 flows along the drip irrigation pipe 6 and drip irrigation and fertilization operations are carried out on the plum tree basin through the seepage holes on the side wall of the drip irrigation pipe 6. When the double-layer protective mechanism 19 is deployed, the upper explosion-proof net 1902 resists the impact of mountain storms, the lower light-transmitting membrane 1901 provides rain protection and heat preservation, and the pressure relief hole 1906 releases the wind pressure inside the umbrella body to prevent the protective structure from being ruptured by strong winds.

[0045] When the double-layer protective mechanism 19 needs to be retracted during fruit tree pruning and harvesting operations, first loosen the locking screw 12 to release the locking constraint of the rotating disk 11. Then, drive the rotating disk 11 to rotate via the handwheel 13. The rotating disk 11 drives the inner rod 10 to rotate via the transmission sprocket 9. The inner rod 10 drives the outer gear 28 and the inner gear ring 25 to rotate via the flexible transmission mechanism 29. The upper gear 27 drives the unloading drum 26 to unload the line, and the lower gear 24 drives the take-up drum 23 to take up the line. The traction line 22 moves on the roller 21, and the traction line 22 pulls all the loading blocks 190. 4. The loading block 1904 slides synchronously along the outer end of the frame rod 14 towards the root of the loading cylinder 30. The loading block 1904 drives the explosion-proof net 1902 and the light-transmitting film 1901 to fold towards the center of the umbrella frame through the clamping screw 1903. The double-layer protective mechanism 19 gradually rolls up. After it is retracted, the locking screw 12 is tightened to lock the rotating disk 11, keeping the double-layer protective mechanism 19 in the retracted state, which is convenient for personnel to carry out agricultural work such as pruning and harvesting. If it is necessary to retract the frame rod 14, the locking screw 17 can be loosened and the sleeve 16 can be slid down. The sleeve 16 pushes and pulls the frame rod 14 through the connecting rod 15 to change the opening angle.

The middle part of the traction line (22) is rotatably fitted onto the roller (21). The top of the frame rod (14) is provided with symmetrically distributed mounting grooves (20). The traction line (22) is slidably installed in the mounting grooves (20), and both ends of the traction line (22) slide through the loading cylinder (30). The inner wall of the loading cylinder (30) is rotatably embedded with a take-up cylinder (23) and a release cylinder (26). One end of the traction line (22) is fixed. The other end of the traction line (22) is wound and installed on the rod of the feed drum (26) connected to the take-up drum (23). The upper and lower sides of the inner wall of the loading drum (30) are coaxially rotatably equipped with an external gear (28) and an internal gear ring (25). An upper gear (27) is meshed on the outer side of the external gear (28), and a lower gear (24) is meshed on the inner side of the internal gear ring (25). The lower gear (24) is coaxially fixedly connected to the bottom end of the take-up drum (23), and the upper gear (27) is coaxially fixedly connected to the top end of the feed drum (26).

8. The irrigation and fertilization device for planting lodging-resistant honey plum trees in karst mountainous areas according to claim 1, characterized in that: The flexible transmission mechanism (29) includes a transmission cylinder (2901). Two transmission cylinders (2901) are coaxially rotatably embedded on the inner wall of the loading cylinder (30). An external gear (28) is coaxially fixedly installed on the top of the transmission cylinder (2901) at the higher position, and an internal gear ring (25) is coaxially fixedly connected to the bottom of the transmission cylinder (2901) at the lower position. The upper end of an inner rod (10) is coaxially arranged on the inner side of the transmission cylinder (2901), and a force plate (2902) and a thrust plate (2905) are respectively arranged on both sides of the upper end of the inner rod (10).

9. The irrigation and fertilization device for planting lodging-resistant honey plum trees in karst mountainous areas according to claim 8, characterized in that: A force plate (2902) is fixedly installed on the inner wall of the transmission cylinder (2901). A thrust plate (2905) is fixedly installed on the side of the inner rod (10) away from the force plate (2902).
