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。
In this paper, the effects of single-layer black nylon shade net, double-layer black nylon shade net, green plastic coated film cloth and white cloth on the surface temperature, humidity, emergence and emergence rate of gekko genkwa were studied. One white cloth has better insulation effect, higher germination rate, convenient watering, one-time low investment, a wide range of sources of raw materials, large-scale production in the promotion and application. Plastic film and single-layer sunshade with the emergence of seedlings have a better effect, but there is also a one-time investment of the larger, less common source of white cloth and other shortcomings, the conditions can be promoted.
