Abstract

The invention relates to an agricultural soil loosening liquid fertilizer, a method for preparing the same and application of the agricultural soil loosening liquid fertilizer. Each liter of the agricultural soil loosening liquid fertilizer comprises major elements including nitrogen, phosphorus and potassium, humic acid and soil loosening agents. The content of the major elements in each liter of the agricultural soil loosening liquid fertilizer is higher than or equal to 200 g / L, the content of the humic acid in each liter of the agricultural soil loosening liquid fertilizer is higher than or equal to 30 g / L, and the content of the soil loosening agents in each liter of the agricultural soil loosening liquid fertilizer is 1-19 g / L. The agricultural soil loosening liquid fertilizer, the method and the application have the advantages that the agricultural soil loosening liquid fertilizer is high in hydrolytic resistance and flocculation capacity and has an excellent soil loosening function, problems of hydropenia of crops, poor fertilizer absorption and the like due to soil hardening and soil texture hardening can be solved, 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 loose soil liquid fertilizer, a preparation method and application thereof. 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 retention and s...
