摘要: 本文用通径分析方法对茶树不同种植密度与茶树骨架形成、分枝结构、蓬面结构三大要素进行对应分析,结果表明:1)随密度上升主干粗度、一、二级分枝粗度下降;2)分枝角度随密度上升而变小;3)随密度上升,小桩数随之增加,其它因子与之呈负相关。由于密度上升后,群体结构的光合面积增大,碳水化合物积累增多,而产量上升。选用合理密度与排列组合时,可用回归方程计算。

Abstract: The path analysis was used to study the frame formations, branch structures and crown compositions in the different planting densities and ways. The results showed that as the planting desities increased, the degree of the main stems and the preliminary and secondary branches decreased and the angles of branching became smaller and the numbers of the branchings grewnp, bnt the other facrors showed negative relations. with the planting densaities rising, the areas of the colony photosynthesis were enlarged, the accumulation of the carbohydrate grew and then the yield increased. The regressive equation can be used to select the suitable plantin densities and ways.
