| 摘 要： | 在9～10年生红富士苹果示范园中，连续两年定树测定单株的干周、总枝量、结果枝数、短果枝率、长果枝率、总叶面积、每果叶面积、单叶面积、比叶重、单果重、总果数和产量。其中总叶面积、每果叶面积、单果重和总果数组成产量形成的最佳多元回归方程，由此建立红富士苹果产量形成的方案。实际应用中，首先确定果实大小指标后根据总叶面积得到叶面积指数，根据叶面积指数由最优多元回归方程中依次分别确定留果量和每果叶面积，从而保证红富士苹果在优质基础上的高产稳产。

Studies on the Establishment and Selection of the Scheme for Fruit Yield Formation of Red Fuji Apple |

| Abstract: | A study was conducted on the demonstrative apple orchard of 33ha in Tianlou village community of Guannan county, in which, the fruit yield reached 26125.5kg per ha and increased stably at a rate of 28.1% every year. Investigation and measuring on the fruit yield (y), circumference of trunk (x 1), total branches (x 2), fruiting branches (x 3), percentage of fruiting spur (x 4), percentage of long fruiting branch (x 5), total leaf area (x 6), leaf area per fruit (x 7 ),leaf area per blade (x 8 ), specific leaf weight (x 9 ), single fruit weight (x 10 ) and No.of total fruits (x 11 ) of each of 30 apple trees of Red Fuji apple (Malus pumila Mill) at nine to ten years old for two years running, showed that the optimal multiple regressive equation of the fruit yield formation of Red Fuji apple consisted of x 6 ,x 7, x 10 and x 11 through step by step regression, from which, the scheme for the fruit yield formation of Red Fuji apple could be established. In application of the scheme, the index of fruit size was first determined, then the leaf area index was obtained from the total leaf area. According to the leaf area index, the total fruits and leaf area per fruit was determined by the optimal multiple regressive equation, respectively. Thus, the stable high yield based on a high quality of Red Fuji apple could be realized. |
