Enzyme bacteria are a group of beneficial microorganisms that can produce a variety of enzymes, such as aerobic bacteria, yeasts, and molds. These microorganisms are non-toxic to humans and animals and are safe to use. Enzymes can produce a variety of enzymes that decompose organic matter in a short period of time. Enzymes fermented and fermented by enzymes are an ideal non-polluting biological fertilizer. This fertilizer mainly depends on the metabolic activity of microorganisms. Its fertilizer effect, which has the characteristics of long and quick fertilizer, can meet the needs of nutrients during the whole growth period of crops, and has a large increase in production rate and low cost. It is the most ideal fertilizer for the development of pollution-free vegetables. At present, there are EM organisms exposed in the city. This biological bacterial fertilizer consists of a group of photosynthetic bacteria, lactic acid bacteria, yeast flora, gram-positive actinomycetes, and a filamentous flora of enzymes. (a) The role of EM's original microbial flora in the following aspects: A. Soil properties can be improved and soil fertility can be improved. Experiments conducted by relevant scientific research units in China show that, compared with chemical fertilizers, EM exposure + pig manure increased soil available potassium by 5%, increased available phosphorus by 31.2%, increased total nitrogen by 15.5%, and soil The more fertile the species grows, the more beneficial the animals (cockroaches, etc.) multiply. Permeate, retain water, and increase air permeability to promote soil pelletization. After three to five years of continuous use, the soil ecology, physical and chemical properties have been completely improved, gradually reduced, and there has been no need for chemical fertilizers and pesticides, and finally no-tillage cultivation has been achieved. B. It inhibits the survival and reproduction of harmful microorganisms, enriches beneficial microorganisms, and forms a regeneration mechanism. It can reduce and gradually eliminate soil-borne diseases and pests and continuous cropping obstacles. C. Herbicides are not used to inhibit and eliminate weeds. D. It can enhance the metabolic function of plants, increase photosynthesis, promote seed germination, develop roots, early flowering, and more robust. E. Low investment and high returns. After several years of use throughout the country, a crop of EM 2 kg was used per mu. One kilogram is 25 dollars, two kilograms are 50 dollars. Yield increase is generally 10-20% higher for grain and oil crops (of which soybeans can increase production by more than 40%); leafy vegetables are increased by more than 8-26%; tuber and tuber vegetables are more productive; fruits and vegetables are preserved Increased by more than 40%, and the single fruit weight, sugar content, and freshness preservation significantly increased. Flowers can bloom ahead of time, flowers are blooming, and flowering time is extended. F. It can improve the quality and produce pure natural green products with great color, good taste and no chemical pollution. (b) How EM is exposed to pollution-free vegetable production Fermentation compost is made with EM crude, which is also the most important. Farmers' friends can draw materials locally, produce their own biological fertilizers, apply them to the soil as base fertilizers, improve soils, and improve soil fertility. Its production method is to use a variety of gluten, weeds, human and animal excreta, crop stalks (straw requires chopped), edible mushroom residue and cake residue, etc., it is best to add some wine slag, these raw materials Mixing and stirring, according to the total amount of 500 to 1000 parts of raw materials, EM original exposed 1 part, brown sugar 1 part, clean water 30-35% (according to the dry humidity of raw materials increase or decrease the proportion of water). Dissolve brown sugar first, pour it into water, add EM original dew, mix well with raw materials, stack compaction, seal with plastic film or canvas, anaerobic fermentation, after 10 days in summer and 15 days in winter, issue distiller's scent Or white, red hyphae appear, indicating successful fermentation. It is also possible to dig a large pit on the ground, use 500 to 1000 times the original dilution of EM, spray the bottom of the pit first, then apply four walls, then apply one layer of material (20 cm thick), and spray 500 times the diluted dilution of EM. Liquid, until filled with pits, and then covered with dirt on the solid, after two weeks of fermentation, there is the smell of distiller's yeast, white, red hyphae can be used. If the temperature reaches above 50 degrees Celsius during fermentation, it should be cooled and then sealed to prevent the destruction of effective substances. Closed fermentation compost can be stored for 3 months. 2. Use EM original dilution (500 times) to soak, seed, root, and spray. 3. The method of using EM raw fermented manure water as top dressing is according to the ratio of EM original dew 1: brown sugar 1: feces water 200, mixing and stirring, covering with a film, stirring once every 1 to 2 days, 5 to 7 days on it Use 200 to 500 times more water when diluted. (C) The specific use of EM exposed on vegetables: A. During the site preparation, EM per acre applied to composting 500 kg of compost (20 centimeters into the soil). B. In the nursery period, soaking with 100 times EM original solution, spraying once with 1000 times EM original dew dilution after emergence, transplanting, planting with 500 times EM original dew diluted roots for 5 minutes after transplanting, or 1000 times EM original dew dilution Liquid rooting once. C. Growth period: One crop of no less than two or three times, spray 1,000 times EM original dilution. (IV) Precautions for using EM According to the law of crop growth during the critical period of crop growth; 2. The use of EM after the rain and evening is the best. (E) The application of EM was exposed in the city. The farmers in Xiqing District of Tianjin applied to Shawo radish. The output of radish doubled compared to normal, and the color is dark, the taste is sweet, the quality is good, and they are sold quickly in the market. High price; Applied to cabbage production, large leaves, high yield, green color; Farmers in Wuqing District, Tianjin, use EM exposed cactus, leaves neat, thick slices, dark green color, sold in the Beijing market Especially good.
