银杏属雌雄异株果树，雌树靠雄树授粉才能结果。授粉效果常受雌雄株距离较远、雄株较矮、花期时差、风力风向不适等因素制约，导致授粉质量差、产量低而不稳。经研究，在雌树上嫁接授粉雄枝，可节约授粉树种植成本，使雌雄花期良好相遇，受精率明显提高，果实品质好，产量提高8 Ginkgo dioecious fruit trees, female trees by male tree pollination in order to result. Pollination effect is often affected by the distance between male and female plants, shorter male plants, flowering time difference, wind and wind discomfort and other factors, resulting in poor pollination quality, low yield and instability. After researching, the grafting of pollination male twig on the female tree can save the cost of pollination tree planting, make the male-male male flower flowering meet well, the fertilization rate is obviously improved, the fruit quality is good and the yield is increased by 8
