本文对檇李的某些生物学特性进行了研究。文中叙述了檇李的树性,各类果枝的比例及其结实量,修剪对枝条类型的效应,根系的分布,花的类型和授粉试验。同时探讨了落花落果、枝条生长、果实膨大和气温、日照的相关性,另外还讨论了檇李低产和分布受限的原因,并提出了提高产量和发展檇李生产的途径。
In this paper, some of the biological characteristics of Zan Li were studied. The article describes the tree species of Li, the proportion of various types of fruiting branches and the amount of fruiting, the effect of pruning on the type of branches, the distribution of roots, the type of flowers and pollination experiments. At the same time, the correlation between the flowering and deciduous fruit, the growth of branches, the fruit enlargement, the temperature and the sunshine was discussed. The reasons for the low yield and the limited distribution of the plum plum were also discussed and the ways to increase the output and develop the plum plum were put forward.
