The combination of nitrogen-fixed biological fertilizers, organic fertilizers, and phosphate fertilizers can effectively promote the development and reproduction of biological bacteria such as phosphorus bacteria, potassium bacteria, and decomposing bacteria, thereby greatly accelerating the decomposition of organic matter and minerals in the soil, making it difficult to provide crops. The nutrient elements absorbed and utilized by the roots are rapidly converted into soluble substances, which provide plants in time, promote the growth and development of the crops, improve the soil structure, and increase the overall fertility of the soil. Since there are very few nitrogen-fixing bio-fertilizers on the market at the moment, I would like to introduce to you a method for producing nitrogen-fixed biological fertilizers. Production method: take 35 grams of brown sugar or 35 grams of corn flour, 5 grams of superphosphate, dry sifting 20 grams of ash, 30 grams of quicklime powder, 2000 grams of black fat mud. Pour the above preparations into a vat or a large vat, and add water to make a paste. Take several pieces of red brick with smooth surface, soak it in boiling water for 20-30 minutes, remove it and place it on a wooden board. Spread thin paste of fertilizer liquid on the whole body of the red brick, and put the brick into the basin. The depth of water is to flood the bricks by 2/3. Then put the water basin in a dark room that is not sunlight, and keep the ambient room temperature at 25～26°C. Usually about 5-7 days, the paste on the brick surface will change from yellow brown to black, then you can use bamboo pieces. Slightly scrape off, spread the mat on the plastic film in the room, after natural drying made of powder that is. How to use: When used, the fertilizer should be applied deep in 20 to 30 cm of moist soil, and maintain good humidity and ventilation conditions. It is best to mix bar fertilizer, pond mud and other organic fertilizer and phosphate fertilizer, and the effect is better.
