不同覆膜条件对设施葡萄温湿度及物候期的影响

Influences of Different Mulching Conditions on Humiture and Phonological Period of Facility Grape

试验在葡萄温室大棚中采用双膜促成栽培、单膜促成栽培、避雨栽培3种覆膜模式,记录、比较棚内温湿度数据。结果显示,3种覆膜模式积温依次为1 881、1 829、1 279℃。促成栽培对于葡萄大棚增温保温效果显著,从而直接促使葡萄物候期提前。其中双膜促成栽培效果最显著。在设施栽培中,可同时采用3种不同栽培模式,拉长市场供应期,增加经济收益。

In this experiment, double membrane forcing culture, single membrane forcing culture and rain shelter culture of three kinds of mulching modes were used in grape greenhouse. We compared the temperature and humidity data in the greenhouse. The result showed that the accumulated temperature of three mulching modes were 1 881,1 829, 1 279 ℃, respectively. Forcing culture had significant effects on temperature increase and heat preservation,which directly prompted the advance of the grape phenophase. And the double membrane cultivation was the most significant. In the facility cultivation,we can use these three different kinds of cultivation modes at the same time to extend the market supply period and increase the economic returns.
