厩肥和人粪尿是农村大宗肥源,是培肥土地和使农作物增产的重要有机肥。但是积攒农家肥要讲科学,否则会影响肥料质量,降低肥效。为了确保农家肥质量,积攒农家肥时必须注意以下几点: 一忌肥料露天敞贮。粪堆露天存放,不盖土不封泥,堆中水分容易蒸发,温度下降,不但不利于肥料腐熟和无害化(指灭害菌杀虫卵),而且会使氮素挥发损失,从而降低肥料质量。据测定,在相同时间内,粪堆盖土封泥的氮素损失10％,而露
Manure and human excrement are rural bulk fertilizer sources and are important organic fertilizers that fertilize land and increase crop yields. But to save farm fertilizer to talk about science, otherwise it will affect the quality of fertilizer and reduce fertilizer efficiency. In order to ensure the quality of farmyard manure, accumulate farm manure must pay attention to the following points: Avoid fertilizer open-air storage. Fecal pile storage in the open air, does not cover the soil does not seal the mud, easy to evaporate the pile of water, the temperature drops, not only is not conducive to fertilizer maturity and harmless (refers to the destruction of fungal insecticidal eggs), but also nitrogen volatilization loss, thereby reducing Fertilizer quality. It is determined that at the same time, manure cover soil clay nitrogen loss of 10%, while dew
