针对新疆库车小白杏坐果率低的问题,研究了不同树体负载量与坐果之间的关系。结果表明:调查树体的长果枝比率高于中果枝和短果枝,而长果枝的坐果率在4类果枝中是最低的,50%和70%疏花处理以及花期喷施营养液可以显著提高坐果率,4种类型果枝的完全花比例依次为中果枝>花束状果枝>短果枝>长果枝。说明长果枝由于其本身生长较旺负载量较轻,导致树体营养生长和生殖生长失衡,并且形成较多的败育花,从而产生较低的坐果率。而通过疏花和补充营养可以在一定程度上缓解营养生长与生殖生长之间的矛盾,提高坐果率。
Aiming at the problem of low fruit-setting rate of small white apricot in Kuqa, Xinjiang, the relationship between the load of different tree species and fruit setting was studied. The results showed that the rate of fruit branch was higher than that of fruit branch and fruit branch, while the fruit setting rate of fruit branch was the lowest in the fruit branch of 4 kinds. The rate of fruit setting of 50% and 70% Fruit set rate, 4 types of fruiting branches of the complete flower ratio of the order of fruiting branches> bouquets fruiting branches> short fruiting branches> fruiting branches. The results showed that the growth of fruit branches was lighter because of its own growth, resulting in imbalance of vegetative and reproductive growth of trees and the formation of more abortion flowers, resulting in lower fruit set rate. Through the flower thinning and nutritional supplementation can alleviate the contradiction between vegetative and reproductive growth to a certain extent and improve the fruit set rate.
