Preparation process of degradable strong-water-absorption double-slow-release water-retaining fertilizer

Abstract

The invention discloses a preparation process of a degradable strong-water-absorption double-slow-release water-retaining fertilizer, belongs to the technical field of fertilizer preparation, and aims to solve the problems that soil is hardened due to the fact that a large amount of chemical fertilizer is used by farmers for a long time during growth, so that the yield of crops planted in land is reduced or crops are not suitable to be planted; the problems that the existing chemical fertilizer is relatively high in acting consumption rate and short in continuous nutrition supply time, so that the fertilization frequency and the production cost of crops are increased are solved. Fertilizers such as fish bones and chicken bones in crop straw, breeding sludge and kitchen garbage are crushed into powder and then mixed and fermented to form an organic compound fertilizer with multiple elements, the soil quality is improved with the assistance of a soil conditioner, liquid ammonia is infiltrated with a matrix fertilizer, and the matrix fertilizer is rolled and twisted into compound particles; a pore structure on the surface of the compound particles is matched with a coated starch single coating layer to realize slow release of fertilizer substances, so that the continuous action time of the fertilizer is prolonged; according to the invention, crops can be fully and continuously nourished by the fertilizer, and the soil environment is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a preparation process of a degradable strong water absorption double slow-release water-retaining fertilizer. Background technique [0002] Fertilizers refer to substances that can supply nutrients for crop growth and development, improve soil properties, and improve crop yield and quality. It is an important means of production in agricultural production. Generally divided into organic fertilizers, inorganic fertilizers, biological fertilizers. It can also be divided into farm fertilizers and chemical fertilizers according to the source. According to the amount of nutrients contained, it is divided into complete fertilizer and incomplete fertilizer; according to the characteristics of fertilizer supply, it is divided into direct fertilizer and indirect fertilizer; according to the content of nutrients, it is divided into nitrogen fertilizer, potassium fertilizer...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a preparation process of degradable strong water-absorbing double-slow-release water-retaining fertilizer, which aims to solve the above-mentioned background technology. When agricultural crops are grown, a large amount of chemical fertilizers are used for a long time, which will cause soil compaction, resulting in a decrease in the yield of land planted crops or The problem that it is not suitable for planting crops, and the consumption rate of the existing chemical fertilizers is fast, and the application of fertilizer to crops will be consumed in a short period of time, resulting in a relatively short period of continuous supply of nutrients to crops by fertilizers, and the fertilization of crops Increased number of times and increased production costs
