Layered fertilizer applicator for improving soil in saline and alkaline land

Abstract

The invention discloses a layered fertilizer applicator for improving soil in a saline and alkaline land, and belongs to the field of saline-alkaline soil fertilization equipment. The layered fertilizer applicator comprises a supporting frame, wherein the top end of the supporting frame is fixedly provided with a fertilizer can, the left and right sides of the front face of the supporting frame are provided with supporting wheels respectively, a front fertilization mechanism comprises a discharge module and a cutting module, and a rear fertilization mechanism comprises a discharge module, an adjusting module and a cutting module. According to the layered fertilizer applicator for improving the soil in the saline and alkaline land, the length of a stirring blade in the front fertilization mechanism and the length of a stirring blade in the rear fertilization mechanism make the soil of different depths turned over, which provides conditions for the fertilization work of a turned over area; through the stretch and retraction of an air cylinder, the height between the whole rear fertilization mechanism and a to-be-contacted surface is adjusted so that the fertilizer applicator can perform targeted fertilization according to the salinization degree in the soil, thereby increasing the utilization rate of fertilizers, and the bad influence on the improvement effect of the saline-alkaline soil caused by too much or too little fertilizing amount is accordingly avoided.

Description

technical field [0001] The invention relates to the field of fertilization equipment for saline-alkali soil, in particular to a layered fertilizer applicator for saline-alkali soil improvement. Background technique [0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with capillary water, and after the water evaporates, the salt accumulates in the surface soil; it refers to the phenomenon or process in which soluble salt accumulates in the soil surface. The saline-alkali soil in my country has a large area and a wide distribution. It is generally distributed in plains or basins with flat terrain and deep soil layers, and has not been well developed and utilized due to the harm of salinization. However, with the impact on land productivity and resources With the improvement of demand, people's awareness of soil saline-alkali land management is constantly improving, and the design of fertilization devices for ...
