A kind of bio-coated organic and inorganic microbial fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizer, and particularly relates to biological-envelope organic and inorganic microbial fertilizer and a preparation method thereof. The fertilizer is prepared from, by weight, 10-30% of compound microorganism bacterium agents, 10-50% of major elements, 2-15% of medium trace elements, 5-50% of organic matter, 10-40% of calcium carbonate, 10-40% of kieselguhr and 1-10% of lactate, wherein the organic matter comprises one or more of molasses, polyaspartic acid and humic acid. According to the biological-envelope organic and inorganic microbial fertilizer and the preparation method thereof, the compound microorganism bacterium agents are used, so that the microorganism bacterium agents and the major elements can be applied together and the activity of the major elements cannot be lowered, the strain survival rate is high, the chemical fertilizer applying quantity is reduced, soil is improved, the soil fertility is enhanced, the soil ecology environment is improved, and the crop quality and yield are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a bio-coated organic and inorganic microbial fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an important means of production for increasing crop yield and harvest. In recent decades, due to the widespread application of chemical fertilizers, my country's grain production has doubled. However, due to the long-term use of chemical fertilizers, the soil in our country is no longer "healthy", and the soil properties have deteriorated. Problems such as soil compaction, soil acidification, salinization, and destruction of soil microbial diversity have become more and more prominent, and have directly led to soil barrenness. , Soil failure, etc., affect the sustainable development of agriculture, and the quality of agricultural products deteriorates, manifested as shortened shelf life, dim color, excessive nitrate content, etc., directly af...

AI Technical Summary

Problems solved by technology

[0005] In the existing microbial fertilizer preparation process, most of the process of adding bacterial agents in the granulation process is used. High temperature treatment will lead to the death of a large number of beneficial microorganisms, greatly reducing the effectiveness of the fertilizer after it is put into the soil; poor repeatability and stability

At the same time, because the beneficial microorganisms in microbial fertilizers cannot directly contact with chemical fertilizers, pesticides, herbicides, etc., otherwise, they will kill beneficial microorganisms and make them inactive. Therefore, it is difficult to add active bacteria to microbial fertilizers. There are problems such as the inhibition of microorganisms and the complexity of the process and the difficulty in meeting the quality requirements of the final product
