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 quality of the role of bio - fertilizer: Bio-fertilizer can improve soil fertility, which is its main role, such as various nitrogen-fixing bacteria fertilizer, can increase the nitrogen source in the soil, the solution of phosphorus and potassium fertilizer can dissolve the soil insoluble phosphorus and potassium, Soil phosphorus (P), potassium (K) elements of the source. In addition, bio-fertilizers can promote crop growth and improve the quality of agricultural products. A variety of bio-fertilizer into the soil, can produce different growth hormone, stimulate the growth of crops, such as "5406" actinomycetes bio-fertilizer, not only antagonize the role of pathogens disease prevention bacteria, but also secrete cytokinin Crop growth. Fungal bio-fertilizer not only in helping crops to absorb phosphorus, zinc and copper and other mineral elements have a strong role, as well as enhance the crop of water, water to improve the role of crop drought resistance. As the bio-fertilizer can produce and help the crop to absorb the use of a variety of nutrients, so the quality of agricultural products have greatly improved, can change the fertilizer produced by the "melon is not fragrant, fruit is not sweet, tea tasteless" status, The indicators to meet the green food standards.

Q: Is the bio-fertilizer organic or inorganic?: Bio-fertilizer is organic fertilizer, from the part of the biological itself, after fermentation.

Q: How to use bio-fertilizer and fertilizer: Pure bio-fertilizer can not be a single application, with organic fertilizer, fertilizer with the application in order to give full play to its effectiveness. Such as: soybean rhizobia, phosphorus activator, bio-potash and so on. Organic - inorganic - bio - compound fertilizer, it is organic fertilizer, inorganic fertilizer, biological agents combined with three kinds of fertilizer products, both contain the nutrients needed for crops, but also contains micro - organisms, it can replace fertilizer for crop growth and development. Such as the current market sales of bio-organic compound fertilizer, green food special fertilizer, bio-organic compound fertilizer. Are in the manufacturing process, add biological agents, shorten the production cycle of organic fertilizer, increase its quick-acting ingredients. Bio-organic fertilizer and traditional organic fertilizer is the difference between the factory, specialized production, it was also called fertilizer for refined organic fertilizer. Bio-fertilizer specific use methods are: 1. Rhizobia fertilizer using a variety of legumes produced by artificial cultivation of various formulations of rhizobia fertilizer, mainly in the legume plant sowing for seed dressing, the general use of 0.5 kg per mu The

Q: Prospects for bio - fertilizer: Bio-fertilizer production cost is low, the application effect is good, does not pollute the environment, not only after the increase in production, but also to improve the quality of agricultural products and reduce the amount of fertilizer in China's sustainable development of agriculture occupies an important position. China's growing population, people's living standards continue to improve, the quantity and quality of agricultural products put forward higher requirements. While the cultivated land is decreasing, the application rate of chemical fertilizer increases, the production cost rises linearly, the environment deteriorates and so on. These conditions provide a good development opportunity for bio-fertilizer. At the same time, the development of bio-fertilizer itself has laid the foundation for expanding the application. The world's population is soaring, and society's demand for food and fertilizer is becoming increasingly urgent. However, it is difficult to maintain the sustainable development of agriculture, and it is necessary to develop bio-fertilizers in the future because of the limited resources of the raw materials and energy sources for fertilizer production.
