Developing green foods requires a lot of high-quality farmyard fertilizers. In summer, the temperature is high, the humidity is high, and farmyard manure is volatile. Therefore, it should be stored scientifically to increase the utilization rate of agricultural fertilizer.
First, human excrement: human excreta is a liquid fertilizer, organic nitrogen is easily broken down into ammonium carbonate. Storage method: First, scaffolding on the pit cover, sun protection, rain, anti-volatilization. Adding sheds and caps can reduce losses by 40% to 50%. Second, the use of soil-enriched nitrogen, a human urine mixed with three fine dry soils, the use of fertilizer solution and dry soil permeability nitrogen absorption nitrogen, than the single deposit The human waste can reduce the loss of 15% -30%.
Second, pig manure urine: always keep the bar inside the straw, broken grass, dry soil and other litter to absorb urine and nitrogen conservation, keep out of the bar often pits, Qin Qin mats.
Third, cow dung urine: It is a high moisture content, poor ventilation, decomposition decomposition slow, low temperature fermentation of cold fertilizer. The storage method is: to accelerate the decomposition of concentrated heaps, it is best to incorporate a certain proportion of human excreta when accumulating, and pay attention to frequent turning, promote decomposition decomposition.
Fourth, chickens and ducks manure: Chicken duck dung is perishable thermal fertilizer. The storage method is: Select a dry, cool place to build a dung shed, cover the heap uniformly, preferably with pig dung, mixed and preserved.
V. Plant ash: It is the main source of potassium in agricultural fertilizers. Potassium in plant ash is mainly in the form of potassium carbonate, followed by potassium sulfate and potassium chloride. They are water-soluble potassium, which can be directly absorbed and used by crops. The places where they are stored must be protected from rain and moisture and should be stored separately in indoor or ash sheds. Conditional farmers can use old chemical fertilizer bags, textile bags and other bags, and pile them in the corners of warehouses, garages, convenience stores, etc., and move them out when they are used. The method is also good.
