我们从1985年以来,对花量大的苹果树,进行了“间距疏果法”的试验和大面积示范工作,取得了良好效果,现介绍如下。 一、“间距疏果法”的基本作法 “间距疏果法”就是根据品种特性、树体营养状况以及花果多少,确定适宜的留果间距和留果量,把多余的花、果全部去掉。留果的基本标? Since 1985, we have carried out experiments and large-scale demonstration experiments on large-volume apple trees with good results and are presented below. First, the “pitch and thinning method,” the basic practice “Sparse and Thinning Law” is based on species characteristics, tree nutrition and the number of flowers, to determine the appropriate spacing and the remaining fruit retention fruit, the excess flowers and fruit removed . The basic standard of fruit retention
