摘要
为探明冬季温度变化对砀山酥梨生长发育的影响,以露地栽培砀山酥梨为对照,设置棚室加温、棚室栽培的砀山酥梨为处理。结果表明,初春温度变化,对砀山酥梨芽存活、花序坐果率无显著影响;对坐果率和果实的脱萼率有显著影响。温度升高,花芽和叶芽萌动期均提前5 d左右,且花期相对较长;对花芽和叶芽的萌发速率也产生不同程度的影响。
In order to investigate the effect of temperature changes in early spring on the development of Dangshan pears, the open cultivation was treated as controls (CK), and the calefactive greenhouse cultivation and greenhouse cultivation were performed as the treatments. The results showed that the temperature changes in early spring did not significantly affect survival of bud and rate of anthotaxy fruiting, but affected the rate of fruiting and sepal falling. The increasing temperature resulted in the germination stage of floral and leaf bud bringing for- ward for 5 days with relatively longer florescence. Moreover, this would also affect the germination speed of flo- ral and leaf bud to some extent.
