摘要
通过对板栗190个结果母枝长度、粗度和结栗棚数的调查分析,证明结果母枝粗度和结实力呈明显的直线相关。其相关系数为0.672899,而结果母枝长度对产量影响较小。为此培养相壮的结果母枝是增产的有效途径之一。
Through the investigataion on length and thickness of 190 Castanea mollissima fruiting branches,and number of fruiting branches with fruit produced on them,it was found that thickness of fruiting branches is linearly related to fruit-producing capacity,and its correlation coeffi- cient is 0.672890.The length of fruiting branches has a little influence on fruit production.Cultivating thick and sturdy fruiting branches is one of effective ways in increasing the chestnut production.
