摘要
以日光温室内栽植的 4a生大石早生李为试材 ,分析了大石早生李结实能力与枝径、冠径、干径、树高、分枝数、离授粉树的距离的相关关系。结果表明 ,授粉树距离是影响结果数量的主要因素。根据回归方程可得出授粉品种配置的最佳距离。
The 4-year-old Dashi early ripening plum, planted in solar greenhouses, were used as materials to analyze the correlated relationship between fruiting ability and branch girth, crown girth, trunk girth,tree height, quantities of ramification and distance to pollination trees The results showed that the distance to pollination trees was the main factor that affected fruiting quantities According to the regression formula, the optimum distance of pollination trees arrangement could be got, and it presented the reference basis for arranging the pollination trees in greenhouses for Dashi early ripening plum
