Problems solved by technology

[0002] Due to loose sandy soil particles, strong fluidity, and weak interaction between particles, it is easy to damage land resources and land productivity under the action of external forces such as water, gravity, and wind, resulting in land surface erosion and water loss.
In addition, the degree of salinization is getting heavier and the soil nutrients are poor, which greatly restricts the productivity level of planting and the recovery ability of vegetation in sandy soil areas.

Abstract

The invention discloses a fertilizer applicable to sandy saline-alkali land and a preparation method of the fertilizer. The fertilizer applicable to the sandy saline-alkali land comprises the following components: attapulgite clay, coal fly ash, humic acid, plant straw, municipal solid waste sludge, bentonite, polyacrylamide, carboxymethyl cellulose, hydroxyethyl starch and microbial powder in a weight ratio of (20-30):(20-30):(12-16):(18-22):(4-8):(2-4):(2-4):(1-3):(1-2):(0.5-1.5). The fertilizer applicable to the sandy saline-alkali land provided by the invention can effectively improve thesoil structure of the sandy saline-alkali land, reduce the salinity, reduce the content of sand in the soil, improve the content of nutrients in the soil, improve the compactness of the soil, and canenduringly and effectively improve the sandy saline-alkali land through cooperating with plant cultivation.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a fertilizer suitable for sandy saline-alkali land and a preparation method thereof. Background technique [0002] Due to the loose sandy soil particles, strong fluidity and weak interaction between particles, it is easy to damage land resources and land productivity under the action of external forces such as water, gravity, and wind, resulting in erosion of the land surface and water loss. In addition, the degree of salinization is getting heavier and the soil nutrients are poor, which greatly restricts the productivity level of planting and the recovery ability of vegetation in sandy soil areas. Therefore, improving the aggregate structure of sandy soil, increasing the content of water-stable aggregates in sandy soil, increasing soil fertility, and reducing salinity have become the focus of research on improving sandy saline-alkali land. Contents of the ...
