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 mixture fertilizer for improving sandy saline-alkali soil and a preparation method of the fertilizer. The fertilizer includes desulfurization gypsum, fly ash, organic fertilizer, fulvic acid, clay, sand binder, a composite water retaining agent, a saline-alkali soil improver, expanded vermiculite, and a microbial powder agent according to weight ratio of 22-30:8-12:18-22:12-16:6-10:6-8:4-8:4-6:2-4:0.5-1.5. The mixture fertilizer can effectively improve the soil structure of the sandy saline-alkali soil, reduces saline alkali degree and content of sand in the soil, andcan improve content of nutrients in soil and increase compactness of the soil. With combination of plant cultivation, the mixture fertilizer can durably and effectively improve the sandy saline-alkali soil.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a mixed fertilizer for improving 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. ...
