Problems solved by technology

However, the use of a large number of chemical fertilizers has brought about great environmental problems in successive years. The decline in fertilizer utilization rate, soil compaction, water retention capacity decline, and soil erosion have further aggravated the deterioration of the soil physical and chemical environment, threatening the sustainable development of agriculture to a large extent. food security
[0003] At present, most compound fertilizer enterprises produce water-retaining and loose soil functional compound fertilizers by adding chemical flocculants. There are two main categories: 1. Inorganic chemicals, mainly polyaluminum chloride, aluminum sulfate, etc. There are obviously large dosages, high aluminum ion content, certain poisonous effect on crops, obvious enrichment effect, threat to human health, long-term application, and secondary pollution to soil; 2. Organic polymers, mainly It is polyacrylamide, which has good soil loosening and water retention effects, but it is made of chemical raw material acrylamide, and a large amount of toxic acrylamide monomer remains, which is harmful to crops and human body
In the existing compound fertilizer production process, clay or bentonite is mostly used as a binder. When the amount is small, the effect is not great. If the amount is large, the content of active ingredients will be reduced. It is not easy to dissolve in the soil, affecting the release of fertilizers, and is of little use to the soil.
[0004] And solve the above problems, can have again rich in nutrients, reduce water and soil loss, improve soil moisture, increase soil bulk density, loosen soil, significantly improve nutrient utilization rate, promote the nutrient type water-retaining soil loosening compound fertilizer of increasing agricultural production and income, in the prior art None reported in

Abstract

The invention discloses a preparing method for nutritional type water conserving and soil loosening compound fertilizer. The method comprises the following steps that 1, compound enzyme liquid is prepared; 2, microelement is thrown into gamma-polyglutamic acid liquid to carry out a chelation reaction to prepare a pelleting bonding agent; 3, a pharmacy agent, an enzyme preparation and citric acid are selected, fermented and filtered in a pressing mode to obtain mycelium residues, the mycelium residues are thrown into a high-temperature and high-pressure wall breaking tank, saturated steam is introduced, and instant pressure reducing is carried out to enable mycelium cell walls to be broken to prepare a chitin and chitosan organic mixture; 4, the organic mixture obtained in the step three is dried and crushed to obtain a water conserving and soil loosening master batch, the master batch and inorganic nutrients are mixed and stirred uniformly, and thrown into a pelletizer, the pelleting bonding agent is sprayed into the mixture, and pelleting and screening are carried out to obtain the nutritional type water conserving and soil loosening compound fertilizer. The fertilizer has the advantages of being rich in nutrient and capable of reducing water loss and soil erosion, increasing soil moisture content, increasing soil bulk density, loosening soil, remarkably increasing the nutrient utilization rate, and promoting the agriculture yield and income increase.

Description

technical field [0001] The invention relates to a preparation method of a compound fertilizer, in particular to a preparation method of a nutrient-type water-retaining loose soil compound fertilizer.
