Problems solved by technology

[0003]In recent years, people have used a lot of chemical fertilizers and chemical pesticides unreasonably when planting rice, which not only consumes a lot of non-renewable resources, destroys the soil structure, but also pollutes The quality of rice and the natural environment have been affected, and the health and survival of human beings have been affected.
The chemical fertilizers used for rice in the prior art have the defects of low fertilizer utilization rate, inability to improve soil, incomplete nutrition, and environmental pollution

Abstract

The invention discloses a special bio-compound fertilizer for rice and a production method thereof, relating to the technical field of the production of bio-compound fertilizers. According to the production method, the characteristics of fertilizer requirement of the rice are followed, urea, potassium chloride, monoammonium phosphate, biological additives, humic acid, ammonium bicarbonate, calcium silicate, and EDTA (Ethylene Diamine Tetraacetic Acid) chelated zinc are mixed according to a formulated mixture ratio, and the special bio-compound fertilizer is obtained through even mixing, pelleting, drying, cooling, screening, blending and then packaging. The special fertilizer has the advantages of comprehensiveness in nutrients, high utilization ratio, performance in increase of rice yield and rice quality and no pollution.

Description

technical field [0001] The invention relates to the technical field of biological compound fertilizer production, in particular to a biological compound fertilizer for rice and a production method thereof. Background technique [0002] Rice is native to tropical Asia and is widely cultivated in China. Rice is an annual grass plant, about 1.2 meters high, with long and flat leaves, and panicles composed of many spikelets. Rice likes high temperature, high humidity, and short sunshine, and has no strict requirements on soil, and paddy soil is the best. The minimum temperature for seedling germination is 10-12°C, and the optimum temperature is 28-32°C. At the tillering stage, the daily average temperature is above 20°C, and the optimum temperature for panicle differentiation is about 30°C; the low temperature prolongs the differentiation of branches and spikelets. The optimum temperature for heading is 25-35°C. The optimum temperature for flowering is about 30°C, if it is...
