Straw high-temperature fertilizer method

Straw high-temperature fertilizer is to mix the crop stalks with humans and livestock manure in a certain proportion and conduct scientific accumulation and fermentation. This is an advanced technology that integrates straw returning technology and high-temperature fertilizer technology to build high-quality organic fertilizers. First, the fertilizer method 1. Preparation of materials. 1 months before fertilization prepared crop straw, human waste, livestock and poultry manure and the appropriate amount of horse dung, grids. 2. Mix the prepared crop stalks into small pieces of about 3 cm. Then mix man, livestock and poultry manure and crushed straw in a ratio of 3:7 and pour enough water. 3. Pile up rot. Prepare a pile of horse manure or griddle, and pour hot water to make a warm heart (heating center). Cover the mixed straw in a warm heart. Above, piled up into a round pile, the stack height should not be less than 1.5 meters. After stacking, pay attention to management, prevent trampling of people and livestock, measure stack temperature every day, and control stack temperature at about 60°C. The maximum temperature cannot exceed 70°C. At this temperature is conducive to microbial activity, can speed up the decomposition rate of straw. After 7-10 days of fermentation, pour the heap. Every time after 7 days, 1 time, 3 to 4 times, it can be fermented after 30 days. The fermented straw fertilizer has characteristics of blackness, rottenness, and smell, and is grasped into a group by hand and released. Second, note that if the amount of fermented straw in the straw, the fermentation effect is better; after the fermentation is good, if not used for a while, can be spread out the dung heat, ready for use; open-air fermentation, if the temperature is too low, found that dung When you run off the frost, timely cover it with a well-mixed stalk or cover the top of the stack with a plastic sheet to facilitate heat preservation. When you pour it, you will find that the manure is too dry and there is a gray powder. It is necessary to add water; the stalk fertilizer should not be fermented excessively. Use it with poor fermentation, so as not to affect fertilizer efficiency. Third, fertilizer methods and quantities of farmland can be used as basal fertilizer, or application of excrement, generally 1 to 1.5 tons per 667 square meters; open field vegetable base, 667 square meters 2-3 tons; greenhouses and greenhouses can be Layer fertilization or application, apply 3-5 tons per 667 square meters. Fourth, the application of effects 1. Fertility, improve soil fertility conditions determined by fermented sap fertilizer organic matter content greater than 15%, total nitrogen 1.2% -2.5%, total phosphorus 0.58% -0.712%, total potassium 2% - 3.1%, and contains a large number of medium and trace elements necessary for plant growth, a variety of nutrient indicators far higher than all kinds of pure human, animal waste. Applying straw fertilizer can improve the soil, fertilize the soil, increase the organic matter of the soil, and supplement the soil nutrient. 2. Loosing the soil and increasing the yield of the crop Fertilizing the straw fertilizer results in loose soil and reduced bulk density, which can make the root system of the crop well-developed, resistant to lodging, and enhanced in stress tolerance. According to surveys, straw fertilizer 1.5 tons per 667 square meters, continuous application of 3 years, the average increase in food crop production 10% -15%, soil organic matter increased by 0.105%, volume density decreased by 0.06 grams / cubic centimeter, soil porosity increased by 4%. 3. Make full use of resources to prevent pollution At present, there are many crop stalks that have been abandoned to farmland every year in rural China. Some farmers burn these stalks, which not only wastes resources but also causes air pollution. If these straws can be used to produce high-temperature fertilizer, these resources will not only be used, but also will reduce the input of fertilizers, increase crop yields, and improve the quality of agricultural products. At the same time straw fermented fertilizer or the production of pollution-free agricultural products preferred organic fertilizer.
