Abstract

The invention relates to a microbial organic fertilizer and a preparation method thereof, and belongs to the field of fertilizers. The microbial organic fertilizer is prepared as follows: seven kindsof bacteria including thermophilic bacillus, bacillus licheniformis, bacillus subtilis, aspergillus oryzae, thermophilic actinomycete, thermophilic fungus and saccharomyces cerevisiae are sealed and fermented according to a certain proportion to form a fermentation liquid, straw is crushed and mixed with rice bran, pig manure urine and trace elements according to a certain proportion to obtain a raw material mixture, the mixed fermentation liquid of the seven kinds of bacteria and the raw material mixture are fully stirred and dried in air according to a certain proportion to obtain the microbial organic fertilizer. The microbial organic fertilizer has the advantages of scientific proportioning, high organic matter content, full fermentation of various strains, environment-friendly raw materials, high fertilizer efficiency and capability of fully protecting ecology and improving soil.

Description

【Technical field】 [0001] The invention relates to the field of organic fertilizers, in particular to a microbial organic fertilizer and a preparation method thereof. 【Background technique】 [0002] In the past two decades, the extensive use and excessive use of industrial chemical fertilizers in the field of agricultural planting has caused unprecedented damage to the soil of my country's farmland. The common problems are that the acidity and alkalinity of the soil is too high or too low, and the soil texture of the farmland is heavy. Surface compaction; the low content of soil organic matter affects the activity of microorganisms and other problems. In addition, long-term single and excessive application of chemical fertilizers will not replenish humus in time, which will also cause soil compaction and cracking. [0003] In the land where the soil is compacted, the root activity of the crops will decrease due to lack of oxygen and cannot develop normally. The best way to cha...
