Abstract

In order to solve the problem of high fruit drop rate of Zizyphus Jujuba ‘Zhanshanmizao’, this experiment used Z. Jujuba ‘Zhanshanmizao’ as material, throught measuring the fruit drop rate and organic nutrient changes with different tree vigor, to study the dynamic change and drop mechanism of fruit drop. The results showed that there were two fruit drop peaks in fruit growing period, which were early June and late August respectively. Different tree vigor has influence on the fruit drop rate of Z. Jujuba ‘Zhanshanmizao’, the general trend was weak tree > strong tree > medium tree. The soluble sugar content and soluble protein content significantly affected the fruit drop rate, the difference of soluble sugar content in the fallen fruit compared with the normal fruit reached the maximum in early July, while the difference of soluble protein content between the fallen fruit and the normal fruit reached maximum in the early and middle stages of fruit ripening. However, titratable acid content and Vc content have little effect on the fruit drop rate.
