黑穗醋栗幼树单位面积上相对结果枝量是产量构成的主要因子。初果期(3-4年生)的单丛枝量和单株产量有明显的正相关,同一地块的r=0.973*( n=3),提高栽植密度或增多丛内定植株数,可促使增加结果枝量,但结果枝量过多易引起早衰.通过调查得出,亩结果枝保证在4万左右为好,一般株行距 The relative results per unit area of ​​black currant saplings were the main factors of yield composition. There was a significant positive correlation between the single shoots per plant and the yield per plant in the initial fruit stage (3-4 years old). The r = 0.973 * (n = 3) in the same plot increased the planting density or increased the number of colonized plants, Increase the results of the amount of branches, but the results too much can easily lead to premature failure.According to the survey, mu results in the branches around 40,000 to ensure that the general line spacing
