Abstract

The invention relates to a special slow release fertilizer for maize, which aims to resolve the problems that the pertinence of prior fertilizer is not strong; the application is not convenient enough; the versatility is also not fully embodied, and plastic film can be damaged when applying as well as ''burning'' and other problems. The invention adopts the technical proposal that: after mixing 0.1% to 0.3% of hydroquinone coated urea, calcium superphosphate particle(comprising 14% of P2O5), potassium sulfate particle (comprising 33% of K2O), zinc sulfate, 2.5% polyvinyl alcohol, then special slow release fertilizer for maize is obtained through packaging with slow release capsule coating. The special slow release fertilizer has the advantages of ability to apply the base fertilizer for film-covered maize one-and-for-all, no need to apply during middle growth stage, without ''burning'', without damage to the plastic film when applying, ability to satisfy the needs for various nutritional ingredients in maize growing, and increased yield for maize kernel; in addition, compared with the conventional fertilizer with the same nutrient quality, the yield can be increased for 14 to 17%, and the applying labor can be saved for two per mu, and the cost is saved for 20 yuan per mu.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special compound fertilizer. Background technique [0002] Special fertilizers are physical and chemical technology products of balanced fertilization technology. They are an important condition for cultivating soil fertility and promoting sustainable agricultural production. They have the advantages of strong pertinence and regionalization, high fertilizer utilization rate, convenient application, multiple functions, and high technical content. They represent the future of fertilizers. The direction of development has attracted the attention of farmers, fertilizer companies and government departments. In the "National Tenth Five-Year Science and Technology Development Outline", special fertilizers are identified as one of the industries that will be supported and developed in the future, bringing unprecedented opportunities and challenges to the research and production of special fe...
