苹果是一种异花授粉果树,开花期若遇不良气候(阴雨、降温、下黄沙等),由于影响了传粉授精,就会降低座果率和产量。为了克服花期不良气候影响,立脚抗灾夺丰收,我们于1976年在莲溪县郪口公社五大队果园进行了放蜂,人工辅助授粉提高青苹座果率的试验。现将试验结果报导如下。
Apple is a cross-pollination of fruit trees, blooming occasionally bad weather (rainy, cool, yellow sand, etc.), due to the impact of pollination and insemination, it will reduce the rate of fruit set and yield. In order to overcome the unfavorable climates of the flowering period and set foot on the ground to resist the bumper harvest, we conducted a test in 1976 on the orchard of the Fifth Brigade of the Qunkou Commune in Lianxi County. The test results are reported below.
