疏花疏果是苹果栽培中的一项重要工作,对提高果品质量有明显作用。疏花疏果须掌握八项“原则”。 1.根据树的大小合理留果 可按树干的粗度估算单株适宜的留果数。其计算公式为:单株留果数=(3～4)×0.08×干周2×保险系数。公式中第一项(3～4)系数,由果实大小来确定,晚熟大型果如红富士、北斗等用3,中小型果如早熟品种早捷、别拉,中熟品种嘎拉
Thinning fruit thinning is an important work in apple cultivation, to improve the quality of fruit has a significant role. Thinning thinning fruit to master the eight “principles.” 1. According to the size of the tree, a reasonable retention of fruit can be estimated according to the thickness of the trunk of the plant suitable for the number of leaves. The calculation formula is: the number of leaves per plant = (3 ~ 4) × 0.08 × dry weeks 2 × insurance coefficient. Formula in the first (3 to 4) coefficient, determined by the size of the fruit, late-mature large fruit such as Red Fuji, Beidou and other 3, small and medium-sized fruit as early varieties early, do not pull, medium maturity varieties Gala
