摘要：在已进入盛果期的山核桃成林中,在山核桃雌花和雄花的盛花期,用薄壳山核桃花粉进行人工授粉杂交试验,结果表明:虽然林间有大量的山核桃花粉存在,但杂交仍然取得成功,座果率达26.8%～89.9%,平均52.8%,比对照平均43.2%高出9.6个百分点,坚果经济性状明显改善。因此,只要在山核桃林中,适当配植一些雄花盛花期与山核桃雌花的盛花期相吻合的薄壳山核桃优良品系,是可以达到增加山核桃授粉机会,提高座果率,并改善坚果经济性状的目的的。
Experiments were conducted on artificial pollination of Carya cathayensis by male C illinoensis pollen in C. cathayensis stand during full-bloom stage of female C. cathayensis and male C. illinoensis. The result demonstrated that percentage of fertile fruit reached 26.8% - 89.9%, averaged by 52.8%, while that of the control was 43.2%（mean）. The nuts had improved economic traits.
