Problems solved by technology

The traditional process is simple and easy to implement, and the investment scale is small, but it has many disadvantages, such as large area, long production cycle (about 1-2 months or even longer), high labor cost, poor production environment, and limited by geographical and climatic conditions. Large impact, prone to secondary pollution (odor, etc.), incomplete decomposition or unstable quality, etc.

Embodiment 1

[0035] A method for producing functional microbial fertilizer by two-step fermentation, the steps are:

[0036] 1) Material pretreatment and pre-fermentation

[0037] Mix pig manure (moisture content 72%) with crushed rice bran (30 mesh) in proportion (pig manure: rice bran = 5:1, weight ratio), adjust the final water content of the material at 60%, and adjust the water content according to 0.5% of the material weight is inoculated with high-temperature decomposing bacteria, and the material is stacked after mixing. The height of the material stack is controlled at 1.2m, and the stack is long and 2m wide, and the constant temperature is maintained at 60°C for 4 days.

[0038] The high-temperature decomposing bacteria is an organic material decomposing agent (Chengdu Tianxing Agricultural Technology Co., Ltd.).

[0039] During pre-fermentation, PC sunshine panels are installed on the indoor ceiling to increase the material temperature.

[0040] 2) High temperature fermentatio...

Embodiment 2

[0054] The microbial fertilizer prepared in Example 1 was used as a base fertilizer, mixed with soil and applied to potted planting of capsicum and Chinese cabbage seedlings, and the commercial fertilizer was used as a control to compare its growth-promoting and disease-resistant effects.

[0055] See Table 2 and Table 3 for the application effect of the microbial fertilizer prepared by the present invention on capsicum; see Table 4 for the application effect on Chinese cabbage.

[0056] Table 2 The growth-promoting results of the microbial fertilizer prepared in Example 1 on pepper seedlings

Abstract

The invention discloses a method for producing a functional microbial fertilizer by two-step fermentation and the application of the functional microbial fertilizer. By the method, the functional microbial fertilizer is obtained by pre-fermentation, primary high-temperature fermentation and secondary functional fermentation. According to the method, efficient aerobic fermentation is adopted for the whole process, the method is short in production cycle, high in yield and flexibility, stable in product quality and wide in application range, and can be used for producing functional biological fertilizers from various organic waste, production lines in different scales can be established according to needs, the influence of regions, seasons and climates is little, and the obtained product has 50 to 68 percent of total organic matters, total nutrients of 5.5 to 8.8 percent, water content of 15 to 30 percent, viable count of 5.8*10<8> to 4.5*10<10>CFU / g and germination index of over 85 percent.

Description

technical field [0001] The invention belongs to the technical field of functional microbial fertilizers, and more specifically relates to a method and application of two-step fermentation for producing functional microbial fertilizers. Background technique [0002] my country's annual solid organic waste, including livestock and poultry manure, kitchen residues, straw and crop processing waste, forest and forest product processing waste, livestock and aquatic product processing waste, fermentation residue, rice bran, sludge, etc., is about There are more than 10 billion tons, and only a very small part is efficiently utilized as a resource, and most of them are naturally decayed and flowed into rivers or burned, which is one of the important sources of pollution. To solve such a huge accumulation of organic waste, the previous practice has proved that it is feasible to use it to produce functional microbial fertilizers, which will alleviate the soil compaction, soil quality d...
