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 find out the effect of winter temperature on the growth and development of Dangshan Pear, Dangshansu pear with greenhouses and greenhouse cultivation was used as the control. The results showed that the change of temperature in early spring had no significant effect on the survival of pear shoots and inflorescence fruit setting rate in Dangshan Mountain, but had significant effect on the fruit setting rate and the rate of decilication of fruit. The temperature increased, buds and leaf buds germinating period of about 5 d ahead of time, and relatively long flowering; flower buds and leaf buds germination rate also have varying degrees of impact.
