Preparation method of bioorganic fertilizer

Abstract

The invention discloses a preparation method of a bioorganic fertilizer. The method is characterized by adopting a complex microorganism bacterium agent formed by bacillus subtilis, aspergillus oryzae, trichoderma reesei, phanerochaete chrysosporium and geobacillus stearothermophilus as a decomposition agent to degrade straws to prepare the bioorganic fertilizer. The preparation method has the beneficial effects that the strain composition of the complex microorganism bacterium agent is new flora composition, which takes full advantage of the physiological activities of strains to generate cellulose, hemicellulose and biological enzymes, such as ligninase, to accelerate the decomposition process of straws, thus preparing the bioorganic fertilizer; the organic straw fertilizer prepared by the preparation method is used as a base fertilizer, so that the contents of available nitrogen, rapidly available phosphorus, potassium and organic matters in soil are higher than those of available nitrogen, rapidly available phosphorus, potassium and organic matters in the soil in which straws are directly used and fertilizers are not applied; the urease activity and cellulase activity of the soil are obviously improved compared with those of the soil in which straws are directly used and fertilizers are not applied.

Description

technical field

[0001] The invention relates to an organic fertilizer, in particular to a preparation method of a bio-organic fertilizer. Background technique

[0002] Crop straw is a huge resource with the characteristics of large quantity, variety and wide distribution. According to statistics, the annual output of straw in my country is about 700 million tons, but the utilization efficiency of straw is extremely low, and most of the straw is incinerated and discarded, causing serious environmental pollution and waste of resources. At present, straw is mostly used in agriculture by returning it directly to the field. However, due to the slow decomposition rate of straw returning to the field in cold soil and the decrease in soil temperature, which affects the growth of crops, the proportion of straw returning to the field has always been relatively low. Returning straw to the field through composting is undoubtedly the best way to solve these problems. By composting, the...
