Straw-decomposing inoculant

Abstract

The invention discloses a straw-decomposing inoculant which comprises the following active components: bacillus subtilis, aspergillus niger, trichoderma viride, phanerochaete chrysosporimn and geobacillus stearothermophilus. In the straw-decomposing inoculant, the total content of effective viable bacteria is (1-2)* 10<8> / ml. With adoption of the straw-decomposing inoculant, the fertilizer prepared from straws can be rapidly degraded, and the normal compost fermentation is performed in advance for at least 15 days. When the straw organic fertilizer prepared from the straw-decomposing inoculant is used as the base fertilizer, alkali-hydrolyzale nitrogen, rapid available phosphorus, potassium and organic contents in the soil are higher than that in the soil in which straws are directly utilized and no fertilizer is applied, and the urease activity and cellulase activity in the soil are obviously higher than that in the soil in which straws are directly utilized and no fertilizer is applied.

Description

technical field

[0001] The invention relates to a decomposing agent, in particular to a decomposing agent for degrading straw and a preparation method thereof. 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 problem...
