[0024] Embodiment 1

[0025] Referring to Figures 1 to 6 As shown, a protection component for the growth of seedlings in saline-alkali land, characterized in that it includes a wind protection cylinder 2 and a protection cylinder 3. A plurality of fixed plates 4 are provided at the bottom of the wind protection cylinder 2 and the top of the protection cylinder 3. The fixed plates 4 are penetrated by the ground needle 1. The top of the wind protection cylinder 2 is threadedly connected with a sealing cover 5. One end of a tube 6 is fixedly installed on the upper part of the wind protection cylinder 2. The other end of the tube 6 is located inside the wind protection cylinder 2. The other end of the tube 6 is fixedly installed with an infusion needle 7. A flow regulator 8 is slidably installed in the middle of the tube 6. The protection cylinder 3 includes connecting blades 31 and protection blades 32 that are slidably connected in an alternating manner. Both the connecting blades 31 and the protection blades 32 are arc-shaped, and a circular protection cylinder 3 can be formed between a plurality of connecting blades 31 and protection blades 32. The wind protection cylinder 2 is used to protect the harmful factors to the plants on the ground. The protection cylinder 3 is used to protect the saline-alkali soil to prevent the soil infiltration liquid in the saline-alkali land from converting the nutrient soil into saline-alkali soil. The infusion needle 7 continuously provides nutrients during the growth of the seedlings, ensuring sufficient nutrition for the seedlings. The wind protection cylinder 2 and the protection cylinder 3 are fixed at the same time, so that the protection cylinder 3 also acts as the ground needle 1, thereby further improving the stability of the wind protection cylinder 2.

[0026] The wind shield 2 is a conical transparent structure, with a plurality of ventilation holes 21 arranged in an array on the wind shield 2, a transparent liquid collection tube 22 arranged on the top of the wind shield 2, a conduit 6 arranged at the bottom of the liquid collection tube 22, and a thread arranged on the outside of the liquid collection tube 22. The conical structure makes the wind shield 2 more stable in windy weather, the ventilation holes 21 are used for the plants to breathe, and the liquid collection tube 22 is filled with nutrient solution.

[0027] The top of the connecting blade 31 is fixedly mounted with a fixing plate 4, and both ends of the connecting blade 31 are provided with trapezoidal guide rails 311. The connecting blade 31 and the protective blade 32 are staggered and slidably connected so that after the plant matures, the connecting blade 31 and the protective blade 32 can be taken out in sequence without damaging the root of the plant.

[0028] A protective cavity 321 is provided inside the protective blade 32, and acidic fertilizer is arranged inside the protective cavity 321. A plurality of transition holes 322 connected to the protective cavity 321 are provided outside the protective blade 32, and gauze 323 is provided inside the protective blade 32. Dovetail grooves 324 are provided at both ends of the protective blade 32, and the dovetail grooves 324 are adapted to the trapezoidal guide rail 311. The transition cavity enables the alkaline soil permeate of the saline-alkali land to be neutralized with the acidic fertilizer, and the soil permeate is absorbed by the seedlings through the gauze 323, thereby protecting the seedlings and preventing the seedlings from being burned. Moreover, as the acidic fertilizer in the protective cavity 321 is gradually reduced, the nutrient soil in the protective tube 3 is gradually assimilated with the saline-alkali land, so that the growth environment of the plants will not change significantly.

[0029] The sealing cover 5 is cylindrical and matches with the liquid storage cylinder 22. A through hole 51 is provided at the top of the sealing cover 5. A push rod 52 is slidably installed in the through hole 51. A piston 53 is provided at the bottom of the push rod 52. The piston 53 is interference fit with the inner wall of the liquid storage cylinder 22. A spring 54 is sleeved between the piston 53 and the top of the inner wall of the sealing cover 5. After the sealing cover 5 is rotated, the sealing cover 5 squeezes the spring 54, causing the spring 54 to contract, thereby providing a continuous thrust for the piston 53, thereby increasing the pressure in the liquid storage cylinder 22, so that the nutrient solution in the liquid storage cylinder 22 can be discharged.

[0030] The infusion needle 7 is provided with a plurality of infusion holes 71 in an array, and a filter screen 72 is provided on the infusion hole 71. The infusion needle 7 is located underground, so that the nutrient solution is output from the root of the plant, making it easier for the plant to absorb, and the filter screen 72 prevents the infusion needle 7 from being blocked.

[0031] Example 2

[0032] The flow regulator 8 of the utility model has the same structure as the flow regulator 8 of the existing medical infusion device;

[0033] A rubber sealing ring is arranged on the outer side of the piston 53 of the utility model to improve the sealing performance between the piston 53 and the liquid accumulation cylinder 22;

[0034] The inner wall of the sealing cover 5 of the utility model is provided with an internal thread adapted to the liquid accumulation cylinder 22.

[0035] Embodiment 3

[0036] Working principle: When planting seedlings on saline-alkali land, first dig planting pits on the saline-alkali land, put the protection cylinder 3 into the planting pits, then fill nutrient soil into the protection cylinder 3, plant the plant seedlings in the nutrient soil, then select appropriate acidic chemical fertilizers and add them into the nutrient cavity of the protection blade 32, then place the wind protection cylinder 2 above the protection cylinder 3, at the same time insert the infusion needle 7 into the nutrient soil, make the catheter 6 fixedly connected with the infusion needle 7, and use the ground needle 1 and the fixing plate 4 to fix the protection cylinder 3 and the wind protection cylinder 2 on the ground. After that, add nutrient solution into the liquid accumulation cylinder 22, and after installing the sealing cover 5 on the liquid accumulation cylinder 22 by means of thread disassembly, adjust the flow rate of the nutrient solution through the flow regulator 8 in the middle of the catheter 6;

[0037] When supplementing nutrient solution to the plant, first close the catheter 6 through the flow regulator 8, then rotate the sealing cover 5 to make the sealing cover 5 push the spring 54 to compress. After the spring 54 is compressed, it continuously pushes the piston 53, and the piston 53 pressurizes the inside of the liquid accumulation cylinder 22, so that the nutrient solution can flow out through the catheter 6. Then open the flow regulator 8 and control the flow rate of the nutrient solution to prevent the nutrient solution from flowing out too fast, resulting in waterlogging of the roots of the seedlings;

[0038] During the growth process of the plant, the soil permeate of the saline-alkali land enters the protection cavity 321 through the transition hole 322 and is neutralized with the acidic chemical fertilizer in the protection cavity 321. The neutralized permeate is absorbed by the plant through the gauze 323. As the acidic chemical fertilizer decreases, the neutralized permeate gradually becomes alkaline, so that the alkalinity of the permeate absorbed by the plant gradually increases, thereby gradually increasing the alkalinity of the nutrient soil during the growth process of the plant, and gradually converting the nutrient soil into saline-alkali soil during the growth process of the plant, and then gradually improving the adaptability of the plant;

[0039] After the plant matures, take out the ground needle 1 to disconnect the connection between the wind protection cylinder 2 and the protection cylinder 3, then pull out the connecting blades 31 from the ground in sequence. After all the connecting blades 31 are pulled out, then pull out the protection blades 32 in sequence, so as to ensure that the roots of the plant will not be damaged, and then improve the survival rate of the plant.
