The production of bio-fertilizer is difficult for the average individual due to a one-off investment of tens of thousands or even millions of yuan. However, as long as the appropriate technology is mastered and little capital is invested, a more practical biological fertilizer can be obtained by using the soil method. The following describes three kinds of production methods for reference by small businesses and farmers. 1. Solid-type biofertilizer 1. Take 1,000 kg of ordinary shale, 50 kg of wheat bran, 10 kg of brown sugar, 5 kg of corn starch, 20 kg of microbial composite strain (solid, dry weight, the same below), and add about 100 kg of water. Mix well, build a stack height of 1 to 1.2 meters, a width of 0.8 to 1 meter, and an unlimited length. When the heap temperature rises to 45 to 50 degrees Celsius, turn it over, turn it over 5 times, spread out to dry, and pack it for use. . The application rate is per acre: 600 kg of greenhouse vegetables, 1000 kg of fast-growing vegetables, and 800 kg of green lawns and flowers. 2. Corn stalk, wheat straw (any crop stalk can be) 5000 kg, 200 kg of wheat bran, 30 kg of brown sugar, 30 kg of corn starch, 100 kg of microbial composite strains, straw can be long or short, and it is best to reach 5～ 10 cm long, add water and mix well together, build a stack of 1.5 meters high, 2 to 3 meters wide, length is not limited, the material under the 30 cm temperature 50 ~ 55 °C when the first turn of the heap, after the temperature measurement At the peak, maintain 10 hours and then turn the heap, turn a total of 6 to 8 times, and then mix well can be directly used as a basal, can also be stored after drying. Generally 5000 kg (wet weight) is applied per acre and quickly turned into the soil to prevent direct sunlight from killing the bacteria. Second, liquid biological fertilizers 1. Fresh crop stalks such as stalks of green corn, sweet vines or fresh pastures and 500 kg of fresh weeds, 15 kg of wheat bran, 10 kg of brown sugar, 5 kg of corn starch, 2 kg of soybean flour, 12 kg of superphosphate and 15 kg of microbial complex bacteria. The stalks or weeds are crushed and mixed together, placed in cement ponds with a depth of 0.8 to 1 meters and a volume of about 6 cubic meters, and temporary excavation pits and plastic membranes can also be used for emergency use. The mixed grass, bacteria, etc. were spread on the bottom of the pool, covered with 1 to 2 layers of shade nets, and then pressed several sticks of wood, and then watered until they were not about 30 centimeters of forage, and the pool was shaded. When the temperature is above 25°C, an air bubble appears on the water surface after a few days. After removing the water cover, the forage material is shaken with a fork-like tool, and it is continued to make it become bacteria. After about 20 days, the broth can be used as top dressing. On an acre basis, 2000 kg of greenhouse vegetables, 3,000 kg of fast-growing vegetables, 1,500 kg of field crops, 1600 kg of fruit trees, and 2,500 kg of green lawns and flowers. Article Shi, points Shi can be, pay attention to soil pressure or pressure, so that the fertilizer into the rhizosphere and below sites. 2. Take 5 kg of dry chicken manure, 2 kg of wheat bran, 1.8 kg of bean cake powder, 0.5 kg of brown sugar, 0.2 kg of starch, 30 kg of water, and 1 kg of microbial composite strain. Mix well and put it in an ordinary water tank type container or a small cement tank, cover it with a sunshade net or a grass cover, and pay attention to stirring it once or twice a day to increase oxygen. When the temperature is 25°C, it can be used for 10 days. Application method: the bacteria solution is filtered and the fresh water is used for spraying: 300 times for greenhouse vegetables, 200 times for fast vegetables, 150 times for fruit trees, about 120 times for his crops, 120 times for crops, etc. fertilizer. Third, topdressing bio-fertilizer 1. Wood flour bio-fertilizer: Formula: 1000 kg of wood chips, 100 kg of wheat bran, 20 kg of bean cake, 200 kg of chicken manure, 13 kg of microbial compound bacteria. After the chicken manure is crushed, mix well with sawdust, etc., and add water to wet it so that the moisture content is about 55% to 65%. Build a heap, turn it once a week, turn it 4 to 6 times, and dry it for use. Production points: shade, rain, pest control. Application: For high-yield crops such as greenhouse vegetables as base fertilizer, each formula is applied at one time. Topdressing is divided into 3 times of furrowing or hole application, and then the soil is covered, and water is applied after 3 days of application. For fruit trees, dig holes can be applied. 2. Chicken manure bio-fertilizer: Formula: 1000 kg of chicken manure, 200 kg of wheat bran, 50 kg of wheat bran, and 15 kg of microbial composite strain. The basic production method is the same as above. Application: When basal fertilizer is used, only half of the formula is needed per acre, and when top dressing is applied, it should be divided into 2 to 3 times of furrow application. The method is the same as above.
