A special fertilizer for shrimp and rice co-cropping and its preparation method

Abstract

A special fertilizer for co-production of shrimp and rice, including a three-layer spherical structure coated from the inside to the outside, which are respectively inorganic nutrient layer, organic nutrient layer I, and organic nutrient layer II; the above-mentioned shrimp and rice co-production special fertilizer The preparation method comprises the following steps: preparing organic fertilizer: mixing potassium humate, sheep manure, chicken manure, vermicompost, silicon fertilizer and decomposing agent in proportion, then spraying water, air-drying and pulverizing after 30 days of fermentation; preparation of inorganic nutrient layer: mixing chlorine Potassium chloride, ammonium dihydrogen phosphate, urea and calcium peroxide are added to binder I for granulation; organic nutrient layer I preparation: add inorganic nutrient layer granules to organic fertilizer and binder I to granulate; organic nutrient layer II Preparation: adding organic fertilizer, expansion agent and binder II to granules of organic nutrient layer I to granulate; drying the granules of organic nutrient layer II to obtain special fertilizer granules for co-production of shrimp and rice. The fertilizer has good fertilizer efficiency, high nutrient utilization rate, significantly reduces rice plant diseases and insect pests, and the lobster has a large size and is marketed earlier, and the preparation method is simple, low in cost and easy to operate.

Description

technical field [0001] The invention relates to a special fertilizer for shrimp and rice co-production and a preparation method thereof. Background technique [0002] With the maturity of breeding technology, the development of logistics, the improvement of people's consumption level, the continuous diversification of food scenes, the promotion of the Internet and the continuous inflow of capital, the popularity of crayfish continues to rise. In recent years, the crayfish farming market has been extremely hot, and even the entire aquaculture market has almost reached the point where no one talks about crayfish. The reason is naturally that more and more people like to eat crayfish. [0003] From the perspective of farming methods, it is mainly divided into three modes: pond farming, rice shrimp mode, and mixed farming. Pond farming mainly mixes river crabs and crayfish together to achieve mutual profits of the two products. At present, the aquaculture area of ​​this model i...

AI Technical Summary

Problems solved by technology

Most of the existing special fertilizers for shrimp and rice focus on the technical point that rice requires inorganic and organic nutrients and do not affect the growth of lobsters. Few special fertilizers for shrimp and rice focus on both safe application and technical issues that promote the growth and development of lobsters and accelerate their market launch. superior
