3、WENDU:

梨树喜温,生长期需要较高温度。秋子梨、白梨喜干燥冷凉的气候,抗寒性较强;砂梨喜温暖湿润气候,抗寒性较弱。西洋梨喜夏季干燥气候而不耐夏湿,抗寒力也较差。当土温达0.5℃以上时根系开始活动,6~7℃时生长新根,21.6~22.2℃生长最快,超过30℃或低于0℃时停止生长。温室大棚内气温达到6~8℃时,花芽开始萌动,梨树开花始期要求温度在12℃以上,14~15℃的气温连续3~5天,梨花即盛开;花粉发芽最适温度为25~27℃,花粉管伸长的最适温度为27~30℃,在15~30℃的范围内,温度越高,花粉管伸长越早,完成受精的时间越短,低于5℃时花粉管受冻。花芽分化以20℃左右气温为最好。
