Problems solved by technology

However, the time required for natural composting is relatively long, and the utilization rate of straw is low. Therefore, it is urgent to develop an efficient microbial compound agent to improve the decomposing speed and decomposing rate of straw.

Abstract

The invention discloses a biological organic fertilizer. The biological organic fertilizer comprises the following components in parts by weight: 100-1000 parts of straw and 1-15 parts of compound microbial agent, wherein the active components of the compound microbial agent include bacillus subtilis, Aspergillus oryzae, Trichoderma reesei, white rot fungi and Bacillus stearothermophilus. In the biological organic fertilizer disclosed in the invention, the straw is used as the raw material for compost, and the compound microbial agent facilitating the degradation of components including cellulose, hemicellulose and lignin is added to accelerate the decomposition of the straw to prepare the organic straw fertilizer. When the prepared fertilizer is applied to farmlands, the soil property can be improved, and the yield and quality of crops can be increased. The compound microbial agent can quickly degrade the straw to prepare the fertilizer, and the time cost in preparing the fertilizer using the compound microbial agent is shorter than the time cost in normal compost fertilization by at least 15 days.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to 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 germs and grass seeds i...
