梨树因自花授粉率不高,座果率往往较低,特别是零星分布的梨树,座果率就更低。那么,怎样才能提高梨树的座果率呢? 人工辅助授粉 人工收集其它梨树品种的花粉,在晴天上午九时后,用毛笔粘上花粉授于正在开放的梨花柱头上。也可人工挂花枝,即在梨树开花时,剪取其它梨树品种的花枝,插于玻璃瓶内(瓶内盛水),挂在梨树上,每3株挂1瓶,可提高座果率。
Pear tree because of self-pollination rate is not high, the fruit rate is often low, especially sporadic pear, fruit rate is lower. So, how can we improve the fruit rate of pear tree? Artificial pollination artificial collection of pear varieties of other pollen, on sunny day nine o’clock in the morning, with a brush sticky pollen on the head of pear is open. Can also be artificial hanging flowering branches, that is, when the flowering pear, cut the flowering branches of other pear varieties, inserted in the glass bottle (water bottle), hung on the pear tree, hanging a bottle for every 3, can improve the seat Fruit rate.
