With the improvement of people's living standards, people have put forward new requirements for food quality, and the use of organic fertilizers as the main source of green food has been favored by consumers. At present, the demand for organic fertilizers from the production of green foods is very large, thus promoting the processing and production of organic fertilizers. Organic fertilizer can provide nutrients for crop growth, improve soil structure, enhance soil fertility, increase soil biological activity, stimulate crop growth, and purify the soil environment. The application of traditional organic fertilizers is the direct application of raw manure; the second is the application of artificial rot. Both direct application of raw manure and untreated (decayed) man-made heaped humic fertilizers can cause certain damage to crops, mainly including the following: 1 transmission of pests and diseases; 2 fermentation and burning of seedlings; 3 toxic gas hazards; 4 soil oxygen deficiency; Slow fertilizer effect; 6 low active ingredients, inconvenient transportation, high cost of use. This article uses chicken manure as an example to discuss the production and application of high-efficiency organic fertilizer. 1. Production of High-Efficiency Organic Fertilizers 1.1 Raw materials for production of high-efficiency organic fertilizers a. Chicken manure Chicken manure contains the lowest carbon content in poultry and livestock manure, and has the highest nitrogen content. It is easily fermentable and decomposable, and has a fast-acting effect. It is the basic raw material of this product. b. Active silicic acid sol is a colorless liquid with excellent deodorizing performance. c. Silica is a white or colorless powder that reacts with molten base in the form of microparticles and acts as a dispersant in the manufacture of the product. d. Sulfuric acid is a colorless oily liquid. Industrial products contain impurities, yellow, brown and other colors. In the manufacture of this product, it has the effect of accelerating the manure of chickens and manures, and the concentration is preferably 90%-98%. 1.2 Preparation of Fertilizer 1 First, mix 0.5 parts of active silica sol with 100 parts of 70% silica, and take 10 parts of this mixture, 90% of concentrated sulfuric acid and 10 parts of chicken manure with a water content of about 50%. 100 parts were added into the reaction vessel and stirred at a rate of 30 r/min. At this time, the temperature in the kettle rose, and cooling water was introduced into the jacket to control the reaction temperature at 75-80°C. After a certain period of reaction, the kettle was The temperature began to decrease. At this time, steam was introduced into the jacket to continue the reaction until the mixture in the kettle gradually turned red-brown. Heating was stopped and the reaction was completed. The whole reaction time was about 1 h, and a reddish-brown pulp was obtained. The product is a high-efficiency organic fertilizer. The finished product has a pH of about 6.5, a moisture content of about 5.6%, a nitrogen content of about 4.2%, and an ash content of about 45%. 1.3 Preparation of Fertilizer 2 1 part of activated silica sol, 10 parts of 98% silicon dioxide powder, 10 parts of concentrated sulfuric acid with a content of over 90%, and 100 parts of chicken manure with a water content of about 50% were added to the reaction vessel. 1 conditions for production, the reaction temperature is controlled at 65-70 °C, time is about 1h, red-brown and no foul odor efficient organic fertilizer 2. 2 Application effects of high-efficiency organic fertilizers 2.1 Used as rice basal fertilizer In 2002, a compound fertilizer and high-efficiency organic fertilizer 1 was used as a rice basal fertilizer in a rice experimental field of the agronomy department of Heilongjiang Agricultural Vocational Technical College. The two treatment areas were all 3333m2. The application is full-layer fertilization during soil preparation. Normal compound fertilizer N, P, and K were formulated into a compound fertilizer at a ratio of 1:1:1, with an application rate of 320 kg/hm2; and the application rate of high-efficiency organic fertilizer 1 was 1,250 kg/hm2. During rice growth, both the topdressing and other management practices are the same. Test results: It can be seen from the growth of rice that the application of high-efficiency organic fertilizer 1 is more green than that of the compound fertilizer, and the yellow color of the leaves after heading is fast; the results of the test after rice harvest show that the high-efficiency organic fertilizer is applied. 1 The rice spike length increased by about 4cm compared to the application of compound fertilizer, 1000-grain weight increased by 5-7g, and the yield increased by 42%. The effect was obvious. 2.2 Use as Rice Topdressing In 2002, a comparative experiment was conducted between the High Efficiency Organic Fertilizer 2 and Chicken Manure Compost as Rice Topdressing in the Rice Experiment Field of the Agronomy Department of the Heilongjiang Agricultural Vocational Technical College. Both treatment areas were 667 square meters and the test was conducted under the same conditions. Fertilize with the same amount of fertilizer and the same method of application. The test results showed that rice rotten roots were found after one week of composting with chicken manure, while rice with high-efficiency organic fertilizer 2 had no rotting, and the seedlings grew well. From the above experiments, it can be seen that comparing the application of cheap organic fertilizers to the soil and the application of compound fertilizers and unprocessed organic fertilizers, both the improvement of crop yields and the prevention and control of pests and diseases have become apparent. effect.
