Microbial inoculant for plant fiber alkaline decomposition and soil improvement

Abstract

The invention discloses a microbial inoculant for plant fiber alkaline decomposition and soil improvement. The microbial inoculant is composed of a composite thallus and a carrier. The composite thallus consists of bacillus subtilis, Issatchenkia orientalis, bacillus laterosporus, Bacillus mucilaginosus and actinomycetes. The carrier comprises rice bran, soybean meal, saw dust, cake powder and straw powder. The composite thallus accounts for 5-8% of the weight percentage of the microbial inoculant. The microbial inoculant provided by the invention can promote the absorption of original nutrient elements in microbial carrier and soil, effectively improves soil microflora formation, strengthens the microbial activity of crop rhizospheres, and enhances the phosphorus-dissolving and potassium-releasing ability, thus improving the soil quality. In addition, the microbial inoculant not only can achieve rapid degradation of organic waste in soil and full absorption and utilization of the degraded organic waste by plants, but also effectively solves the problem that organic waste is untreated for a long term and affects the surrounding environment.

Description

technical field [0001] The invention relates to a soil-improving microbial bacterial agent, in particular to a microbial bacterial agent for alkaline decomposing of plant fibers and soil improvement. Background technique [0002] my country is a big agricultural country. Fertilizer plays a very important role in my country's grain production and is one of the largest material investments in farmers' productive investments. At present, the overall level of scientific fertilization in China is not high, and the application of chemical fertilizers has become the main measure to increase agricultural production. The long-term use of chemical fertilizers such as nitrogen and phosphorus will damage the soil structure, resulting in soil compaction, soil degradation of cultivated land, shallowing of the cultivated layer, and water conservation. Fertilizer capacity decreases, pollutes the ecological environment, and directly affects the continuous increase in crop production, agricul...

[0003] With the advancement of urbanization, urban domestic waste is spread in every corner of the city. Some organic waste in domestic waste has begun to flow into farmland areas because it is not suitable for incineration or burial together with other waste. Most of these organic wastes have no After treatment, it is directly discharged into the farmland, and the humus formed by the original straw, fallen leaves, weeds, etc. in the farmland is added, which not only makes it difficult to effectively use the nutrients in it, but also affects the ecosystem of the farmland itself. Lead to the deterioration of soil quality, affecting the normal function of the soil
