Product Description
Bacillus mucilaginosus Krassilnikov, also known as silicate bacteria, has the ability to decompose potassium silicate minerals found in feldspar, mica, and other minerals, as well as phosphorus in apatite. It secretes plant growth stimulants and various enzymes to enhance crop resistance to certain diseases.
Mechanism of action of bacillus mucilaginosus:
1. Decomposition of potassium silicate and aluminum silicate as well as other minerals, to release potassium, silicon, and phosphate. It has functions such as phosphorus solubilization, potassium release, and nitrogen fixation. It also produces organic acids, amino acids, polysaccharides, hormones, and other substances that are beneficial for plant absorption and utilization during growth and replication.
2. After multiplying in the soil, it secretes plant growth stimulants and various enzymes to enhance crop resistance to certain diseases and suppress the growth of other pathogenic bacteria.
3. The potassium content in the bacterial cells is over 33%, and potassium can be released from the bacterial cells after their death and be directly absorbed and utilized by plants.
(1) Absorb mineral nutrients
The mycelium network formed by AMF around the roots extends into the rhizosphere soil, which expands the absorption surface area of plant roots, increases the absorption of mineral nutrients by plants, and improves plant growth conditions. After inoculating AM fungi in maize, peony and other plants, the relative chlorophyll content of plants increases, photosynthesis is enhanced, the absorption of carbon nutrients is promoted, the plant biomass is increased, and the absorption and utilization of nitrogen and phosphorus by plants can be promoted.
(2) Improve plant stress resistance (drought resistance, salt resistance, heavy metal poisoning resistance)
Drought resistance: Inoculation of AM fungi increases the biomass of soybean, corn, lettuce and other plants under drought conditions, and at the same time increases the relative water content of leaves, photosynthetic rate, transpiration rate, reduces stomatal resistance, and enables host plants to use water more effectively, thereby enhancing drought resistance.
Salt tolerance: AMF inoculation can improve the salt stress tolerance of plants such as corn, banana seedlings, cucumber and tomato. Under the condition of salt stress, AMF can enhance plant water absorption and relieve physiological drought; change the ion balance in plants, reduce the damage of plasma membrane and enzymes; improve plant nutrition, hormone level changes, and enhance plant root vitality. Salt tolerance.
Anti-heavy metal poisoning: AM can chelate and passivate heavy metals by mycelium and stay in mycorrhizae, thereby reducing the poisoning of heavy metals in plants.
(3) Improve the soil
Many abandoned lands are extremely barren and heavily poisoned by heavy metals, which are key factors that limit the normal growth of plants in reclaimed soil. Studies have shown that AMF has certain effects on soil structure, nutrients and fertility. Arbuscular mycorrhiza and extra-root mycelium can form a huge mycelial network in the soil, and form large aggregates through physical effects such as reticulation and entanglement; Formation of water-stable aggregates.
Arbuscular mycorrhizal fungi are the bridge between the roots and soil of most plants. The formation of mycorrhizae can cause changes in the physiological and metabolic activities of plant roots, and cause changes in the composition and quantity of mycorrhizal rhizosphere microflora, which accelerates the production of organic matter. Decompose, provide nutrients, improve fertility and stabilize the environment.
