摘 要:在制定出果园1a的施肥方案上,根据土壤条件配制专用肥,从横向和纵向两方面实施果园平衡施肥技术,结合新型肥料生产技术的应用,达到提高肥料利用率,减少肥料投入量,防止过度施肥对环境造成危害等目的。结果表明,以《无公害食品苹果生产技术规程》中推荐的施肥量为对照,在专用肥氮、磷、钾的施入量分别减少1/3和1/2的情况下,补充适当微量元素和有机质,取得了树体营养、产量和品质均显著提高的效果。施肥方案与专用肥的结合,是实现果园标准化施肥的有效途径。Based on analysis of the soil nutrients and the properties of specific fertilizers for apple trees in organic orchards a public un-harmful standard fertilizing formula has been designed. Such formula makes the effects of different fertilizers in balance, increases the efficiency of applied fertilizers and avoids the possible pollution caused by over usage of them. Compared with The Technical Regulations for Production of Organic Apples, this fertilizing formula not only reduces the applied amount of N, P, and K by 1/3 and 1/2 respectively, due to the supplement of trace elements and organic manure , but also much improves the tree growth, organic apple production and quality. It proves such fertilizing formula incorporating specific fertilizers is an effective way for realizing public un-harmful standard fertilizing in organic orchards.
