摘　　要：为了明确不同规格无纺布的保温特性及对大白菜生长和产量的影响,以普通薄膜覆盖为对照,在大棚内进行了无纺布覆盖大白菜的对比试验。结果表明:无纺布的保温效果优于普通薄膜的,能够提高大白菜的出叶速率,增加株高和叶片数,增大叶面积,加快结球速度。综合考虑保温效果和经济效益,可以选择300 g/m2无纺布作为早春大白菜栽培的覆盖材料。In order to make clear the insulation characteristics of different specifications of non-woven fabric and their effects on the growth and yield of early spring Chinese cabbage in facility,taking the ordinary film covering as the check,we carried out the contrast test for non-woven fabric covering of Chinese cabbage in the greenhouse. The results showed that the non-woven fabric had a better insulation effect than the ordinary film,and covering with non-woven fabric could promote the leaf emergence rate of Chinese cabbage,increase the plant height,leaf number and leaf area,and speed up the rate of forming leaf-ball. Comprehensively considering the insulation effect and economic benefits,the author concluded that the 300 g/m2non-woven fabric could be used as the covering material for early spring Chinese cabbage cultivation.
