Q:The practical significance of bio - fertilizer: the development of bio-fertilizer can reduce environmental pollution. The problem of environmental pollution caused by fertilization has been paid more and more attention. In the eutrophication of major lakes in China, the impact from agricultural pollution is even greater than that of industrial pollution. After chemical fertilizers are applied to the soil, there is a considerable part of the loss of nutrients, such as leakage, volatilization and nitrification and denitrification, which will inevitably lead to pollution to the environment, water and soil, In energy and economy is also a waste. The application of biological fertilizers such as nitrogen-fixing bio-fertilizer, not only may be appropriate to reduce the amount of chemical fertilizers (such as the application of high fertility can be reduced by 10 to 30% of the chemical nitrogen fertilizer), and because of its fixed nitrogen stored in the body, Relatively speaking, the chance of environmental pollution is much smaller.

Q:What is biofuel? What is the best to ferment bio-fertilizer?: (Such as rice bran, weeds, human and animal manure, crop stalks (chopped), stems and leaves, sawdust can be, it is best to add some lees residue, edible fungus substrate residue And the cake and other mixed mixing; according to the total amount of raw materials 300-500: Nongsheng Le planted em liquid 1: brown sugar 1: water 30-35% (depending on the material dry and wet increase or decrease the amount of water) ratio, first dissolved brown sugar into the water, And then add Nongsheng Le planted em bacteria liquid, and then mix and mix with the raw materials, stacking compaction, sealed with plastic film or canvas, anaerobic fermentation, summer 10 days, winter 15 days issued a song flavor or white, red bacteria Silk, indicating successful fermentation. Can also dig a pit on the ground, with 300-500 times Nongsheng Le planted em liquid diluent spray the bottom of the pit and walls, and then put a layer of material (20 cm thick) spray 300 times Nongsheng Lok Em liquid diluent, until the filling of the pit, and then cover the soil step on the real, fermented two weeks later, there are wine flavor or white, red mycelium can be used; fermentation, such as the temperature of 50 ℃ or more, Cooling and then sealed fermentation, so as not to damage the effective substances. Closed fermentation compost can be stored for 3 months.

Q:The characteristics of biological fertilizers: The use of bio-organic fertilizers has the following benefits: Bio-organic fertilizers contain a variety of beneficial microorganisms, amino acids, peptides, enzymes, and microbial antibiotics. Bio-organic fertilizer can reduce carbon and nitrogen, carbon and nitrogen ratio is too large, the decomposition rate of microorganisms is slow, and to consume the soil in the effective nitrogen. At the same time can inhibit the plant pathogens, improve the soil microbial environment and physical structure, improve the plant's own immunity, improve crop quality and storage resistance.

Q:How to use bio-fertilizer and fertilizer: When the main bio-organic fertilizer, fertilizer is attached, and gradually increase the amount of bio-organic fertilizer to improve and change the soil fertility and organic content, and finally put an end to the use of chemical fertilizers, organic agricultural products came.

Q:What bio-fertilizer is used in lotus field: Qin Shi, re-top dressing. New lotus field top dressing to be early, the number should be more, fertilizer should be large.
