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...

Embodiment Construction

[0065] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0066] In order to solve the irreversible damage caused by the existing chemical fertilizers to the soil, the long-term use of chemical fertilizers by farmers will cause the soil to harden, resulting in a decrease in the yield of crops grown on the land or the problem that the land is not suitable for planting crops. Please refer to Figure 1-Figure 4 , providing the following preferred technical solutions:

[0067] A preparation proc...
