采用果苗盆栽和大田栽培2种试验方法,在不同时期,施入基肥与追肥后,定期对果树的生长发育情况进行测量,研究速效肥作基肥,不同施肥时期对幼树和成年果树生长的影响;速效肥作追肥,不同施肥时期对果树营养生长、结果和产量的影响;有机肥作基肥,不同施肥方法对产量的影响.结果表明,速效肥作基肥,在幼树发芽前2～3个月施用、成年果树在12月施用效果最好;速效肥作追肥时,幼年果树4月和7月施用为好,结果的成年果树2月施用为好.经方差分析得出,在α=0.01水平上差异显著.这可以指导广大果农合理施肥,使其充分发挥肥效,改变目前普遍存在的肥效不高问题.

Two experimental methods, pot culture and field culture, are adopted. When base manure and top application manure were fertilized at different times, periodical measurements were carried out to survey the growth and development of the fruit trees. The article studied the effects of different fertilizing times to the growth of the saplings and grown up fruit trees, using quick-acting fertilizer as the base manure; the effects of different fertilizing times to the nutrious growth, fruition and yields of the fruit trees, using quick-acting fertilizer as the top application manure; the effects of different fertilizing methods to the production, using organo-fertilizer as the base manure. The result showed that the effects were the best using quick-acting fertilizer as the base manure, when fertilizing to the saplings 2 to 3 months before they sprout and to the grown up fruit trees in December. The best fertilizing time to the saplings is in April and July and to the grown up fruit trees in February using quick-acting fertilizer as the top application manure. Through the variance analysis it showed significant differences at the level ot =0.01. This could instruct the fruit farmers to properly and effectively fertilize, and solve the popular problem of ineffective fertilizing result at present.
