Bacillus mucilaginosus, also known as silicate bacteria, can decompose potassium and silicon in feldspar, mica and other minerals, phosphorus in apatite, and secrete plant growth stimulating hormone and a variety of enzymes to enhance the resistance of crops to some diseases. Bacillus mucilaginosus, is the best strain used as biological fertilizer to promote the transformation of ineffective phosphorus and potassium in soil, increase the supply of phosphorus and potassium in soil and improve crop yield. Bacillus mucilaginosus has strong strength in phosphorus, potassium and silicon dissolution. Bacillus mucilaginosus can produce carbonic anhydrase, which plays a certain role in the fixation of carbon dioxide. Bacillus mucilaginosus can decompose potassium and silicon in feldspar, mica and other minerals, as well as phosphorus in apatite. It has the functions of dissolving phosphorus, releasing potassium and fixing nitrogen. At the same time, it can produce organic acids, amino acids, polysaccharides, hormones and other substances conducive to plant absorption and utilization in the process of growth and reproduction. After Bacillus mucilaginosus propagates in soil, it secretes plant growth stimulating hormone and a variety of enzymes to enhance the resistance of crops to some diseases; It also inhibits the growth of other pathogens. Potassium in Bacillus mucilaginosus is free after cell death and can be absorbed and utilized by plants. As an important functional bacterium in microbial fertilizer, it can improve the content of soil available potassium and phosphorus, and improve crop yield and quality.
Through its life activities in soil, Bacillus mucilaginosus can increase the supply of plant nutrients, stimulate crop growth and inhibit the activities of harmful microorganisms. It has a strong yield increasing effect. At present, it is the microbial agent with the most significant yield increasing effect and widely recognized.
Function of Bacillus mucilaginosus
1. Bacillus mucilaginosus can secrete growth promoting substances such as auxin and gibberellin, increase roots and seedlings, and directly enhance the drought resistance of plants.
Auxin and gibberellin existed in the body of Bacillus mucilaginosus and in the fermentation broth. The content of cytokinin in the fermentation broth was 36 mg / L, the content of gibberellin was 348 mg / L, and the content of indoleacetic acid was 38 μg / ml. The combined action can stimulate crops, increase roots and seedlings, promote crop growth and enhance plant stress resistance.
2. Bacillus mucilaginosus can decompose silicon in soil for plants to use, thicken the wax layer of plants and improve the water holding capacity of plants.
Bacillus mucilaginosus grows and reproduces around seeds or crop roots through bacterial cells. During its metabolism, it produces a large number of organic acids and enzymes, which decomposes insoluble silicoaluminate and other minerals in the soil, and K, P, Si, Mg and Zn are released in the form of ions for absorption and utilization by plant roots. Silicate bacteria grow and reproduce in the soil, decompose insoluble minerals such as metasilicates in the soil, so that plants can absorb a large amount of silicon from the soil, thicken the wax layer of plants, and improve the non-specific immune ability and water retention ability of plants.
3. Bacillus mucilaginosus can promote the formation of soil aggregate structure and prevent soil hardening; Destroy soil capillarity and prevent soil moisture evaporation.
