栽培苹果皆为异花授粉植物,为获得丰产都必须配置授粉树。但有的品种即使在良好的授粉条件下座果率仍然偏低。如1981～1982年兴城温泉地区的元帅的花朵座果率仅3％;在我区南部山区元帅花朵座果率只为9.7％,祝光为8.4％。一般苹果花朵座果率在10％以下则果量不足,采用人工辅助授粉是增产的一项重要措施。
All cultivated apples are cross-pollination plants, pollination trees must be configured for high yield. However, some varieties even under good pollination fruit rate is still low. As of 1981 ~ 1982 Xingcheng hot springs Marshal flower fruit rate is only 3%; Marshal flowers in the southern mountainous area of myrtle fruit rate of only 9.7%, I wish light is 8.4%. Generally, the fruit rate of apple blossoms is below 10%, and the fruit yield is insufficient. The artificial pollination is an important measure to increase yield.
