Abstract

The invention relates to an agricultural soil loosening water-soluble fertilizer, a method for preparing the same and application of the agricultural soil loosening water-soluble fertilizer. The agricultural soil loosening water-soluble fertilizer comprises nitrogen, phosphorous, potassium, 0.1-2.5% of soil loosening agents and the balance citric acid. The total content of the nitrogen, the phosphorus and the potassium is higher than or equal to 50%. The agricultural soil loosening water-soluble fertilizer, the method and the application have the advantages that the fertilizer application rate can be reduced, and problems of hydropenia of crops, poor fertilizer absorption and the like due to soil hardening and soil texture hardening can be solved; the agricultural soil loosening water-soluble fertilizer is good in water solubility and high in flocculation capacity, the permeability of soil can be improved, water, fertilizers, air and heat in the soil can be harmonized, the fertility can be improved, absorption of various nutrients supplied by the agricultural soil loosening water-soluble fertilizer can be promoted, obvious yield increasing effects can be realized, the plantability of the soil can be improved, water consumption can be reduced, the yield of crops can be increased, and the quality of the crops can be improved.

Description

technical field

[0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an agricultural soil loosening water-soluble fertilizer and its preparation method and application. Background technique

[0002] Fertilizers are widely used in agricultural production, but only a small part of nutrients can be absorbed by plants. This is mainly due to the extensive use of single fertilizers and the destruction of soil aggregate structure caused by excessive or too small soil acidity and alkalinity, resulting in Soil compaction is not conducive to the absorption of nutrients by plants.

[0003] In the field of agriculture, polyacrylamide is often used as an additive in the preparation and production of soil slow-release materials, compound fertilizers, functional fertilizers, soil conditioners and other products, and has been published in literature, such as: Chinese patent document 201410150439.2 A soil conditioner for water retenti...
