Abstract

The invention discloses a sandy alkaline-saline soil improving fertilizer prepared with thermal power plant wastes and a preparation method thereof, wherein the improving fertilizer is made with desulfurization gypsum, flyash, urban domestic waste sludge, fulvic acid, plant straw particles, sodium lignin sulfonate, urea resin, an inorganic fertilizer and microbial powder according to the weight ratio of (20-30):(10-14):(11-15):(18-22):(16-20):(4-6):(3-5):(3-5):(0.5-1.5). The improving fertilizer herein is effective in improving soil structure of sandy alkaline-saline soil, lowering alkalinityand salinity, reducing sand content of the soil, increasing nutrient content of the soil and improving soil compactness and can be applied with plant cultivation to constantly and effectively improvethe sandy alkaline-saline soil.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a sandy saline-alkali land improvement fertilizer prepared by waste from a thermal power plant 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 im...
