Is there a procedure for making compost?
First, the raw straw (also available as weed, defoliated, garbage, etc. containing cellulose, hemicellulose, lignin) is smashed to a length of about 6 to 7 cm, 500 kg of straw, 300 kg of yak horse dung (or pig manure). Mix the cow dung) and the human feces and urine 100 kg. Mix them into a rectangular pile of 1.7~2 meters high and 5~6.7 meters wide. Finally, pour 700~800 kg of water and cover the surface of the compost. 3~6 cm thick fine soil to keep warm, keep water and protect fertilizer. After about 1 week, the stack temperature will rise to about 60~70°C (the winter time is relatively long). After 10 days, it can be turned over once and then replenished. After another 10 days, the stack temperature rises for the second time. Turn over the second time and replenish the water.
The sign of composting is that composting materials (such as straw) are nearly black, rotten and stinky. At this time, the compost can be tightened, and the surrounding area is sealed with soil to keep the nutrients for use.
What are the key steps?
In the production of pollution-free vegetables, experts recommend the use of high-quality organic fertilizers such as compost. In composting, in order to make the compost meet the national sanitary standards, the key step is the warming of the compost. Generally, the temperature must be It is raised to 60~70°C, and it is maintained for 6~7 days at this temperature, so that the fertilizer effect can be achieved and the harmful creatures can be killed. The temperature can be measured with a thermometer and can be maintained for up to 10 days after 60 degrees.
How to use homemade compost?
Compost is generally used as a base fertilizer, combined with tumbling, and thoroughly mixed with the soil. Composting is suitable for a variety of soils and crops. Generally, sandy soils can be semi-fertilized compost, and heavy soils must be fully decomposed. The application of compost can increase the soil fertility and supplement the soil with a large number of microbial flora, and bring fertilizers with long-lasting and stable nitrogen, phosphorus, potassium and organic fertilizers such as calcium, magnesium and sulfur, which are beneficial to crop growth. At present, the development of "nuisance-free agricultural products", "green agricultural products", "organic agricultural products" and the multiple cropping index to improve soil fertility, and the application of organic fertilizers such as compost in production are the only way. In the production practice, because different crops require different fertilizers, in addition to the application of compost, it is necessary to apply inorganic fertilizers such as nitrogen, phosphorus and potassium to better exert the fertilizer efficiency.
