Saline-alkali soil fertilizer distributor

Abstract

The invention discloses a saline-alkali soil fertilizer distributor. The distributor comprises a handrail, a handrail support, a rack, a ploughshare, wheels, a motor, a driving gear, a driven gear and a fertilizer box, the handrail is mounted at the upper end of the handrail support installed on the rack, the fertilizer box and the motor are installed on the rack, the fertilizer box is arranged at the left side of the motor, the driving gear is installed on the motor, the driving gear is connected with the driven gear through a chain, the wheels are mounted at the right end of the rack through a bearing, the driven gear is mounted between the wheels and the rack, a fertilizer pipe is mounted at the bottom end of the fertilizer box, the ploughshare is installed at the lower end of the fertilizer pipe, and the fertilizer discharge port is formed in the ploughshare. According to the saline-alkali soil fertilizer distributor, fertilizer comes into the soil by ploughing by the ploughshare, the fertilizing amount can be adjusted, quantitative fertilization can be achieved, the structure is simple, the design is reasonable, the operation is simple, the energy consumption is low, and the promotion and usage are easy.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fertilizer applicator for saline-alkali land. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. The principle of fertilization in saline-alkali soil is mainly to apply organic fertilizers and high-efficiency compound fertilizers, and to control the use of low-concentration chemical fertilizers. Organic fertilizers contain a large amount of organ...

AI Technical Summary

Problems solved by technology

High-concentration compound fertilizer has less ineffective components and less residue, but the amount of chemical fertilizer should not be too much each time, so as to avoid aggravating the secondary salinization of the soil. After applying chemical fertilizer, it should be combined with irrigation to reduce the concentration of soil solution; while the existing Fertilizers are not enough to meet the needs of saline-alkali soil fertilization
