The role of biological fertilizers
1. Improve soil fertility. This is the main effect of bio-fertilizers, such as various self-growing, combined or symbiotic nitrogen-fixing bio-fertilizers, which can fix nitrogen in the air and increase the nitrogen content in the soil; many kinds of microorganisms that decompose phosphorus-potassium minerals, such as silicates. Bacteria can decompose potassium feldspar, mica, and phosphate ore in the soil and make insoluble phosphorus and potassium available.
2. Manufacturing and assisting crops to absorb nutrients. Some bacterial fertilizers, such as 5406 antibacterial fertilizers, can not only increase the effective nutrient content in the soil but also produce a variety of hormones and various vitamins after the application of 5406 antibacterial fertilizers. This will promote the growth of crops; Rhizobium in the rhizobia fertilizer The nitrogen provided by legumes throughout their lifetime accounts for 30% to 80% of their lifetime requirements. VA mycorrhiza is a soil fungus that can coexist with a variety of plant roots. The mycelium extends far from the root and can be absorbed. More nutrients are available for various plants, of which the absorption of phosphorus is most pronounced.
3. Strengthen the plant's stress resistance. After the inoculation of some biological fertilizer strains, they grow and multiply in the roots of crops and become the dominant bacteria in the rhizosphere of crops. They can secrete antibiotics and antibacterial antibiotics, thus inhibiting the growth of many kinds of germs. The mycelium of VA mycorrhiza is due to the large amount of growth in the roots of crops, in addition to the absorption of nutrients beneficial to the growth of crops, it can also increase the water absorption of crops and improve the drought resistance of crops.
The double dome LED Surgical Lamp adopt the new type LED cold illuminant as the illumination source of operating lamps, it is not only benefit for the rapid recovery of surgery illuminate parts, but also improved the doctors' working environment and efficiency extremely; the operation lamp adopts LED as the light source of shadowless surgical lamps, energy-saving effect is remarkable, besides it's energy consumption only be the one tenth of general inscandescent light, one second of halogen lamp;
