Compound starter and preparation method and application thereof

Abstract

The invention discloses a compound starter, which is prepared from the following components in parts by weight: 0.2 to 0.5 part of EM (effective microorganism) bacteria, 0.2 to 0.4 part of bacillus, and 0.1 to 0.2 part of cellulase, 0.1 to 0.2 part of long chaetomium dolichotrichum, 0.05 to 0.2 part of potassium-solubilizing bacteria, 0.05 to 0.2 part of phosphate-solubilizing bacteria, 0.1 to 0.5 part of Trichoderma koningii, 0.05 to 0.3 part of Trichoderma viride, and 0.1 to 0.3 part of Streptococcus faecalis. The invention also discloses a preparation method and application of the compound starter. The compound starter provided by the invention has the advantages of improving the degradation rate of cellulose such as cattle and sheep manure, and having fast fermentation temperature increasing and short fermentation period; the fermented organic fertilizer has the effect of improving the soil, the fertilized crop has relatively good cold and drought resistance and is not easy to lodging, fruit particles are full, the growth period is relatively short, the yield per mu is high, and the content of mineral elements in the fruit is also relatively high.

Description

technical field [0001] The invention belongs to the technical field of fermentation, and in particular relates to a composite starter and its preparation method and application. Background technique [0002] With the rapid development of my country's large-scale breeding industry, a large amount of solid waste and organic wastewater produced by livestock breeding has become one of the main sources of pollution in some areas, especially in the suburbs of large and medium-sized cities. Statistical results show that the total annual discharge of livestock and poultry manure in my country reaches 1.9 billion tons, and it is relatively concentrated. A large amount of poultry manure and sewage not only affect the sustainable development of the poultry industry, but also lead to serious pollution of the rural environment and endanger human health. At present, manure treatment measures at home and abroad tend to prepare organic fertilizers, and the main processes include direct dry...

AI Technical Summary

Problems solved by technology

Reasonable selection of microbial strain combination is the key to the effect of organic fertilizer preparation. At present, there are many strains of microbial fermented poultry manure to prepare organic fertilizer at home and abroad, but the effect is mainly on the treatment of non-ruminant manure such as pigs and poultry. In the process of preparing organic fertilizer from cattle and sheep manure with high content, there are problems of slow temperature rise, low cellulose degradation rate, low degree of decomposition and long fermentation period. Strains are rarely reported, which is not conducive to the efficient treatment of waste carbon sources and manure in large-scale integrated farming ecosystems
