[0002] Saline-alkali land improvement and utilization is a worldwide problem. 7% of the land area, 23% of the cultivated land and 50% of the irrigated farmland in the world are harmed by soil salinization. In China, due to the lack of fresh water resources, high groundwater level and other problems, salt is accumulated in the soil surface layer, and the whole soil is difficult to desalt. Generally, saline-alkali soil has excessive accumulation of Na + , CO3 2- and HCO3 - , high pH, high alkalization degree and high sodium adsorption ratio. The soil granular structure is difficult to form, the structure is poor, the porosity is low, and the air and water permeability is poor.

[0003] In the soil with severe saline-alkali stress, crops can hardly survive. Saline-alkali stress can cause serious ion toxicity, osmotic stress and nutrient imbalance stress. For most plants, the seedling stage is not only the critical period of nutrition, but also the period sensitive to salt stress. As long as the crops can resist salt stress in the seedling stage, they can grow better in saline-alkali soil. By applying fertilizer and organic material to the crop root zone at the same time, a microenvironment with low salt stress, good air and water permeability and sufficient nutrient supply can be constructed for the growth of crops in the seedling stage.

The traditional fertilizing device cannot adjust the amount of fertilizer according to the needs, and is not suitable for fertilizers of different forms, different particle sizes and different components. Uneven fertilization can further aggravate the accumulation of salt in the soil, cause damage to the cotton seedling root system, affect normal growth and development, or cause nutrient deficiency due to insufficient fertilization, limit the growth and biomass accumulation of cotton seedlings, weaken their stress resistance, and thus affect their subsequent yield and quality.

[0021] Please refer to Figure 1 - Figure 5 The utility model provides a technical scheme of the fertilization device for improving the rhizosphere soil environment of the cotton seedling stage in saline-alkali soil:

[0022] In the embodiments of the utility model, please refer to Figure 1 ,Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The utility model provides a fertilizer output assembly, fertilizer output assembly includes box 1, the inside installation of box 1 is equipped with fertilizer output assembly, and fertilizer output assembly includes the first motor 2 installed in the inside of box 1, and one end of first motor 2 is rotatably connected with crankshaft 3, and the inner wall of crankshaft 3 is rotatably connected with first connecting rod 4, and the one end of first connecting rod 4 away from crankshaft 3 is rotatably connected with mounting block 5, and one side of mounting block 5 is fixedly connected with piston 6, and the both ends of crankshaft 3 are rotatably connected with eccentric shaft 7, and one side of two eccentric shafts 7 is fixedly connected with second connecting rod 8, and one end of second connecting rod 8 is rotatably connected with telescopic link 9.

[0023] Need to explain is: through the starting of first motor 2 drive crankshaft 3 occurs rotation, and the output shaft of first motor 2 is connected with crankshaft 3, so that crankshaft 3 rotates along with the rotation of first motor 2, and crankshaft 3 can drive rotatably connected first connecting rod 4 to convert rotary motion into reciprocating motion, and the one end of first connecting rod 4 away from crankshaft 3 is connected with mounting block 5, and mounting block 5 is fixedly connected with piston 6, when first connecting rod 4 moves along with the rotation of crankshaft 3, he will drive mounting block 5 and piston 6 to move reciprocatingly, and through telescopic link 9 push rotatably connected one end second connecting rod 8, can make second connecting rod 8 rotate on the outer wall of crankshaft 3, and the distance that piston 6 pushes can change according to current situation by the characteristics of second connecting rod 8 drive the deflection of the position of crankshaft 3.

[0024] Referring to Figure 5 The outer wall of piston 6 is slidably connected with sleeve 10, one side of the bottom end of sleeve 10 is connected with pipeline 22, one end of pipeline 22 is connected with mounting shell 19, and spray head adjusting assembly is installed in the inner wall of mounting shell 19, and the spray head adjusting assembly includes second motor 11 installed in the inside of mounting shell 19, one end of second motor 11 is rotatably connected with second motor 11, the outer wall of second motor 11 is connected with moving block 13, one side of moving block 13 is fixedly connected with mounting plate 14, a plurality of sliding grooves 15 are formed in the inner wall of mounting plate 14, the inner wall of each sliding groove 15 is slidably connected with sliding rod 16, one end of sliding rod 16 is installed with spray head 18, the other end of sliding rod 16 is connected with hose 17, and one end of each hose 17 away from sliding rod 16 is connected with pipeline 22.

[0025] It should be noted that: the reciprocating motion of piston 6 against sleeve 10 drives fertilizer from fertilizer tank 20 to pipeline 22, entering multiple hoses 17. The rotation of second motor 11 drives screw 12 to rotate, thereby causing movable block 13, which is threaded to the outer wall of screw 12, to move vertically up and down along the axis of screw 12. Because one side of mounting plate 14 is fixedly connected to movable block 13, mounting plate 14 will move simultaneously according to the displacement of movable block 13. When mounting plate 14 moves, multiple sliding grooves 15 are opened on the inner wall of mounting plate 14, and each sliding groove 15 contains a sliding rod. The movable rod 16 has a nozzle 18 installed at one end and is connected to the hose 17 at the other end. When the mounting plate 14 is moved, the multiple nozzles 18 will be adjusted at equal intervals according to the sliding of the sliding rod 16 on the inner wall of the groove 15, so that the spraying is more uniform, thereby reducing the time of repeated operation and improving the overall operation efficiency. At the same time, each nozzle 18 has a telescopic head slidably connected to its inner wall. The extension and contraction of the telescopic head can make the fertilizer accurately applied below the seed. According to different crops, the fertilizer application depth can be adjusted to meet the nutrient needs of its deep roots and provide a good growth environment for the roots.

[0026] See Figure 1 , Figure 2 The bottom of the box 1 is equipped with multiple support legs 21, and there are four support legs 21. The four support legs 21 are rectangular at the bottom of the box 1, and each support leg 21 is equipped with a caster wheel at the bottom.

[0027] It should be noted that the four support legs 21 are arranged in a rectangular shape at the bottom of the box 1, forming a stable support structure that enables the box 1 to maintain balance during operation and prevents it from tipping over.

[0028] See Figure 1 , Figure 2 The top of the box 1 is equipped with a fertilizer tank 20. The bottom of the fertilizer tank 20 is connected to the sleeve 10 on one side. Two supports are installed on both sides of the outer wall of the fertilizer tank 20.

[0029] It should be noted that: as a carrier of fertilizer, fertilizer tank 20 has a relatively large weight and volume. The weight of fertilizer tank 20 is effectively distributed by the support, which enhances the stability of the overall structure and prevents the box 1 from deforming or tilting or the fertilizer tank 20 from falling off due to excessive weight.

[0030] See Figure 5 The inner wall of the hose 17 is connected to the inner wall of the sliding rod 16, and the inner wall of the sliding rod 16 is connected to the inner wall of the nozzle 18. The hose 17 is made of an elastic and wear-resistant material.

[0031] It should be noted that the inner wall between the sliding rod 16, the hose 17 and the spray head 18 is connected to form a complete fluid channel, and the wear-resistant material of the hose 17 reduces the risk of fertilizer leakage due to damage of the hose 17.

[0032] Working principle: by starting the first motor 2 to drive the crankshaft 3 to rotate, when the crankshaft 3 rotates and the first connecting rod 4 connected with it rotates, the first connecting rod 4 can swing, and through the swing of the first connecting rod 4, the first connecting rod 4 can push the mounting block 5 and the piston 6 connected with the first connecting rod 4 to reciprocate in the inner wall of the sleeve 10, when the telescopic rod 9 is extended or retracted, the second connecting rod 8 is driven to displace by the telescopic rod 9, the crankshaft 3 and the first motor 2 are displaced, and the distance between the crankshaft 3 and the first connecting rod 4 is changed, so that the stroke distance of the piston 6 is changed, the amount of fertilizer sprayed by the spray head 18 is adjusted, the rhizosphere soil environment of saline-alkali soil cotton at seedling stage is effectively improved, the growth of cotton is promoted, and the yield and quality are improved.
