Special biological organic fertilizer for rice and preparation method thereof

Abstract

The invention discloses a special biological organic fertilizer for rice. The special biological organic fertilizer for the rice comprises the following components as raw materials in parts by weight:3-20 parts of bacillus subtilis, 20-45 parts of humic acid organic matter, 1-5 parts of polysaccharide, 2-8 parts of amino acid, 0.1-2.0 parts of a carbohydrate activating agent, 10-30 parts of diatomite and 4-8 parts of silicate. The preparation method comprises the following steps: culturing and fermenting liquid bacteria; mixing different batches of bacillus fermented liquid; adding the polysaccharide, the amino acid, the carbohydrate activating agent into the fermented liquid, mixing, sealing and standing for 2 days to obtain fertilizer base liquid; uniformly mixing the organic matter, the diatomite and the silicate proportionally to obtain a fertilizer matrix; slowly adding the base liquid into the matrix, and uniformly stirring to obtain needed fertilizer powder; mechanically granulating through extrusion granulation or roller granulation to obtain fertilizer granules.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special bio-organic fertilizer for rice and a preparation method thereof. Background technique [0002] Rice is the main food crop in my country, and rice is the staple food of more than 65% of the population in my country. In the 60 years since the founding of the People's Republic of China, my country's rice production has been greatly developed, and the planting area has increased from 25.4 million hm 2 up to 31.4 million hm 2 , per unit yield from 1.9t / hm 2 Rise to 6.3t / hm 2 , the total output rose from 48.64 million tons to 200 million tons, the average proportion of rice planting area to grain planting area was 28.3%, and the total output accounted for about 40% of the total food crop output, ranking first in the world. At present, the annual planting area of ​​rice in my country is 30 million hectares 2 , of which the annual planting area of ​​japoni...

AI Technical Summary

Problems solved by technology

[0003] With the development of the agricultural field, people have higher and higher requirements for the yield per mu of rice, which also leads to an increase in the amount of fertilizer used. Appropriate use of fertilizers can effectively increase the yield per mu of grain, and the application of fertilizers can effectively improve soil quality. properties, improve the level of soil fertility, traditional fertilizers have lost a lot of nutrients in fertilizers due to improper material selection or processing technology problems, and the active ingredients in fertilizers may not meet the required standards, which has a negative effect on increasing grain production. great influence
