摘　　要：本文探讨了单层黑色尼龙遮阳网、双层黑色尼龙遮阳网、绿色涂塑膜布和白布等畦面覆盖物对龙胆草育苗过程中畦上表层温度、湿度及出苗期与出苗率的影响。其中白布具有较好的保温效果，出苗率较高，浇水方便，一次性投入低，材料来源广泛，可在生产中大面积推广应用。涂塑膜布和单层遮阳同对出苗均有较好作用，但二者亦存在一次性投入较大、材料来源不如白布普遍等缺点，有条件的地方可推广使用。Four kinds of soil surface shade, i.e. one and two layer of black nylon net,green cotton cloth painted with plastic, and white cotton cloth, were used to growing seedlings of G. scabra. The results showed that four kinds of shade evidently affected the soil temperature, soil moisture and seedling emergency.The treatment with white cotton cloth was better to preserve of soil moisture,the higher rate of emergence was, the more convenient watering was.It is cheap and easy to purchase and should be used wildly in growing seedlings.Benefit to seedling emergence, both of green cotton cloth painted with plastic and one layer of black nylon net were more expensive and limited to fewer supermarket to buy compared with that of white cloth, They should be used only where condition existed.
