Bacillus subtilis forms a probiotic environment in the soil, promotes the formation of agglomerates, improves soil fertility and water retention, increases soil porosity, and promotes root growth. Specifically, it accelerates the mineralization of nutrients and changes nutrients from ineffective and slow-acting states to effective and fast-acting states. At the same time, it accelerates the humification of nutrients, secretes phytase, degrades most of the phytate in the soil; produces auxin, stimulates the growth of crops, and improves the survival rate and emergence rate of seeds.
Bacillus subtilis is widely used in biological fertilizers. When applied to crops or soil, it can colonize in the rhizosphere or in vivo of crops, and has a specific fertilizer effect.
The competition of Bacillus subtilis mainly includes nutrient competition and spatial site competition. It can multiply and colonize rapidly and in large quantities in the rhizosphere, body surface or body of plants and in the soil, effectively repelling, preventing and interfering with the colonization and infection of plant pathogenic microorganisms on plants, so as to achieve the effect of bacteriostasis and disease prevention .
Bacillus subtilis against has excellent control effect against rice blast, powdery mildew & gray mold of Watermelon, cucumber, strawberry, tomato and other crops, potato late blight, soybean, rape sclerotinia, root rot and other fungal diseases of crops such as melons, cereals and Panax notoginseng.
Bacillus subtilis is also a common endophytic bacteria in plants. It is non-pathogenic, does not pollute the environment, and can secrete more than 40 kinds of antibacterial substances, which can quickly inhibit the survival of other pathogenic microorganisms and play a role in “closely” protecting plants. An ideal biocontrol microorganism.
This bacteria is widely distributed in soil and decaying organic matter, and it is easy to multiply in subtilis infusion, hence the name Bacillus subtilis. This kind of bacteria can also emit light and heat in agricultural production. It has a very powerful side. It is a new type of microbial source biological pesticide.
Bacillus subtilis is a common intestinal probiotic, which can prevent pathogenic bacteria from colonizing the intestinal tract, exert “nutritional magic” in places invisible to the naked eye, and can also produce subtilisin, polymyxin, nystatin, short Bacitracin and other active substances can inhibit pathogenic bacteria and enhance immunity, and have a very wide range of applications in medicine and health.
