答:鸡粪含有机质25％、氮素1.63％、五氧化二磷1.54％、氧化钾0.85％。1,000斤纯鸡粪所含的氮磷钾量,分别相当于碳酸氢铵100斤、过磷酸钙120斤和氯化钾15斤。鸡粪不仅含养分高,而且肥劲柔和,是一种高效复合肥。铁岭县熊官屯乡小白梨村农民王为儒,前年承包了5亩水田地,每亩施入发酵好的混合鸡粪(鸡粪50％、乱草25％、土25％)6车,在相同的栽培管理条件下,亩产1,440斤,比没上鸡粪的多100斤。去年每亩又多施1车混合鸡粪,水稻亩产达1,517斤。
A: Chicken manure contains 25% organic matter, nitrogen 1.63%, phosphorus pentoxide 1.54%, potassium 0.85%. 1,000 pounds of pure chicken manure contained in the amount of nitrogen, phosphorus and potassium, respectively, equivalent to 100 kg of ammonium bicarbonate, superphosphate 120 kg and 15 kg of potassium chloride. Chicken manure not only contains high nutrients, but also strong and soft, is a highly efficient compound fertilizer. Wang Weiru, a farmer from Xiaobaili Village, Xiongguantun Township, Tieling County, contracted 5 mu of paddy fields two years ago to apply fermented mixed chicken manure (50% chicken manure, 25% Cultivation and management conditions, 1,440 kg per mu, no more than 100 pounds of chicken manure.
