通过对燕红、燕丰、燕昌等 10个板栗品种雌花的自花授粉 ,不授粉 ,人工定向授粉试验结果的对比 ,来探讨板栗授粉后结实的情况。结论为 :1 板栗不授粉不结果。 2 套种授粉 ,板栗异花结实率比自花结实率显著提高。 3 自然状况下板栗杂交亲合力增强 ,但果实大小不一 ,良莠不齐。 4 板栗建园必须配置好授粉树 ,并配以人工辅助授粉才能实现丰产 By comparing the results of self-pollination, non-pollination and artificial pollination of female flowers of 10 chestnut varieties, such as Yanhong, Yanfeng and Yanchang, the compaction of chestnut after pollination was discussed. The conclusion is: 1 chestnut does not pollinate not result. 2 intercropping pollination, chestnut cross-stature rate was significantly higher than the rate of self-pollinated. 3 natural conditions chestnut hybrid affinity increased, but the fruit size varies, good and bad. 4 Chestnut Park must be configured with a good pollination tree, and with artificial pollination in order to achieve high yield
