一、留果数量的确定 1、产量指标的确定。每个果园,要从树势状况,果园整齐度和栽培管理水平等因素综合考虑,确定合理的产量指标。一般5—8年生初果期红富士苹果园,亩产在500—1500公斤;盛果期红富士苹果园亩产在1500—2500公斤。 2、单株留果量确定。产量指标确定后,按实有株数,分配到每株树上,再根据标准单果重,计算出每株树的预留果数,加上10-15%的保险系数,即为每株树的应留果数。红富士苹果标准单果重为200—250克。每株树的具体留果量,要根据其生长情况和结果数量灵活掌握,壮树适当多留,弱树适当少留,做到合量负担。
First, the determination of the number of fruit retention 1, output indicators to determine. Each orchard, from the tree situation, orchard uniformity and cultivation and management of factors such as comprehensive consideration to determine a reasonable yield indicators. Generally 5-8 years old fruiting period Red Fuji apple orchards, mu produce 500-1500 kilograms; full fruit period Red Fuji apple orchard in 1500-2500 kilograms per mu. 2, to determine the amount of fruit per plant. After the output index is determined, the actual number of trees allocated to each tree, then according to the standard single fruit weight, calculate the number of reserved fruit per tree, plus 10-15% of the insurance factor, that is, each tree Should stay fruit number. Red Fuji apple standard weight of 200-250 grams. The specific retention of each tree, according to its growth and the number of results to be flexible grasp, Zhuang more appropriate to stay, weak tree appropriate to stay less, to achieve the same amount of burden.
