鸡粪中有机质含量达25.5%,纯氮、磷、钾含量分别约为1.63%、1.54%、0.085%,还含有钙、镁、铜、铁、锌等多种微量元素。通过高温发酵产生大量腐殖质,是改良土壤和促进苹果生长的优良有机肥料。但由于鸡粪中有抗生素、盐分及火碱残留,施用时应注意:①必须经过高温发酵充分腐熟后才能使用。②不能连年使用。因连年施用会使鸡粪中含有的盐分、火碱在土壤中积累,会使土壤变得盐碱化,不利于苹果树体的正常生长;土壤中抗生素、

Chicken manure content of 25.5% organic matter, pure nitrogen, phosphorus and potassium content of about 1.63%, 1.54%, 0.085%, also contains calcium, magnesium, copper, iron, zinc and other trace elements. Produced by high temperature fermentation a large number of humus, is to improve the soil and promote the growth of apple excellent organic fertilizer. However, due to chicken manure antibiotics, salt and caustic soda residues, the application should be noted: ① must be fully matured after fermentation at high temperature to use. ② can not be used year after year. Due to successive years will make chicken manure contained in the salt, caustic soda accumulation in the soil, the soil will become salinized, is not conducive to the normal growth of the apple tree body; soil antibiotics,
