银杏又名白果、公孙树,需异花授粉。为提高产量,宜实行人工授粉。人工授粉的主要方法1.挂雄花枝。在雄花开花前的1天,剪下生雄花的枝条,插到装满水的瓶子里,再将瓶子绑在雌树树冠的上风顶部。也可将瓶子绑在一根细竹竿上,再将细竹竿绑在雌树上风处的大枝上。在银杏树较多的地方,需在上风方向每间隔一定距离绑一个插雄花枝条的瓶子,以便授粉均匀。
Ginkgo, also known as ginkgo, Gongsun Shu, to be cross-pollination. In order to increase production, artificial pollination should be practiced. The main method of artificial pollination One day before the flowering of the male flowers, the branches of the male and female flowers are cut, inserted into a bottle filled with water, and then the bottle is tied to the top of the upper part of the canopy of the female tree. The bottle can also be tied to a thin bamboo pole, and then thin bamboo pole tied to the female tree on the wind at the big branch. In the ginkgo tree more places, in the direction of the wind direction must be spaced at intervals to tie a male and female flowers branch of the bottle, in order to pollination uniform.
