摘要
在陕北安塞县早春采用单层遮阳网、双层遮阳网、禾草对仁用杏杏园地面进行覆盖。单层遮阳网、双层遮阳网、禾草覆盖均降低了杏园的地表及30cm土层的土壤温度,0～100cm土壤贮水量相对提高,仁用杏的开花、萌芽等物候期延迟,花期延长,利于仁用杏花期躲过霜冻及座果,座果率分别是不覆盖的3 93倍、5 50倍和6 62倍。
The ground of almond-apricot orchard has been covered with single sunshade net, double sunshade net and grass in the forepart of spring in Ansai county,Nouthern Shanxi, so the soil surface temperature and 30?cm soil temperaturehave been declined, 0～100?cm soil humidity have been relatively increased, florescence, sprouting and others of almond-apricot have been delayed and florescence has been prolonged. These treatments are very advantage to florescence and fruiting to avoid frost. The fruiting rate of almond-apricot that the ground covered with single sunshade net, double sunshade net and grass are 3.93, 5.50 and 6.62 times of almond-apricot that the ground not covered.
