Problems solved by technology

[0002] At present, soil salinization is very serious, which has a great impact on agriculture and is not conducive to planting
Due to the poor physical and chemical functions of salinized soil, the microbial activity in the soil is very low, and plants cannot grow normally, thus bringing adverse effects on agricultural resources.

Abstract

The invention relates to the technical field of fertilizers and particularly relates to a special slow-release fertilizer for peanuts in a saline and alkaline land and a preparation method of the special slow-release fertilizer. The fertilizer comprises the following components: phosphoric acid slurry, diammonium phosphate, potassium carbonate, sodium nitrate, potassium chloride, sulfur, boric acid, fulvic acid, a natural ore fertilizer, a farmyard fertilizer, a biological bacterial powder and a surfactant. By adopting the special fertilizer, the absorption of calcium by peanuts can be promoted, root system development of the peanuts can be promoted, soil structures of the saline and alkaline land can be effectively improved, refractory phosphorus-potassium compounds in soil can be activated and absorbed, soil air permeability can be improved, moreover, root system growth of the peanuts can be stimulated, and diseases and insects in a peanut planting process can be reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer for peanuts in saline-alkali soil and a preparation method thereof. Background technique [0002] At present, soil salinization is very serious, which has a great impact on agriculture and is not conducive to planting. Due to the poor physical and chemical functions of salinized soil, the microbial activity in the soil is very low, and plants cannot grow normally, which has brought adverse effects on agricultural resources. my country's salinized soil area is about 200,000 square kilometers, accounting for about 2.1% of the total land area. In my country's 100 million square kilometers of arable land, about 10% of the land belongs to salinized soil. In addition, there are more than 2,000 hectares of salt wasteland, most of which have not been cultivated. How to reclaim and utilize these salinized soils, expand planting area, and increase na...
