Abstract

The invention relates to a soil conditioner for increasing the permeability of soil, and a preparation method thereof. The soil conditioner comprises, by weight, 50-60 parts of urea, 10-15 parts of calcium superphosphate, 2-4 parts of ammonium molybdenum acid, 5-10 parts of zinc sulfate, 5-9 parts of potassium citrate, 30-35 parts of plant ash, 15-20 parts of biological straws, 100-120 parts of water and 18-22 parts of solid particles. The solid soil conditioner prepared in the invention significantly reduces the hardening hardness of soil and significantly improves the permeability under thesynergistic action of raw materials, makes soil have a very loose aggregate structure, and greatly facilitates the growth of plant roots; and the preparation method has a simple preparation process, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a soil improver for increasing soil permeability and a preparation method, belonging to the technical field of soil improver. Background technique [0002] With the continuous development of agriculture, saline-alkali soil is a type of soil formed by salinization or alkalization. The salt contained in the bottom soil and groundwater, with the evaporation of the ground, the salt in the soil rises to the surface layer. After the water evaporates, Let the salt remain on the soil surface, thus forming a saline-alkali soil. The long-term salt will accumulate on the surface, so that the soil will continue to harden and dry, and the permeability of the soil will continue to decrease, resulting in lower and lower crop yields. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a soil conditioner for increasing soil permeability and a preparation method to solve the problems in the p...
