通过无纺布、遮阳网对冬季蔬菜浮面覆盖的试验表明，２０、３０、４０ｇ／ｍ２无纺布、２５ｇ／ｍ２粘纺布和ＳＺＷ１０型银灰色遮阳网的透光率，分别为８７％、７９％、７３％、７２％和５５％。覆盖后土壤含水量比对照增加５１．４１％～１２．４６％，其中以２５ｇ／ｍ２粘纺布保湿性最好，其次是４０ｇ／ｍ２无纺布。２０ｇ／ｍ２无纺布覆盖增温效果明显，地面温度比不覆盖的对照增加０．８～２．６℃，５～２０ｃｍ土层无论晴天、阴雨天均有增温趋势，尤其是５ｃｍ土层增温达１．８℃。浮面覆盖对矮脚黄小白菜的生长有明显的促进作用。增产效果明显，其规律为３０ｇ／ｍ２无纺布＞２０ｇ／ｍ２无纺布＞２５ｇ／ｍ２粘纺布＞４０ｇ／ｍ２无纺布＞ＳＺＷ１０型银灰色遮阳网，对菠菜的增产效果类同矮脚黄小白菜。
Through the non-woven fabric, sunscreen net floating surface coverage of vegetables in winter showed that 20,30,40 g / m2 non-woven fabric, 25g / m2 viscose fabric and SZW10-type silver shade net transmittance of 87%, respectively, 79%, 73%, 72% and 55%. After covering, the soil water content increased by 51.41% ~ 12.46% compared with the control, of which 25g / m2 viscose fabric had the best moisture retention, followed by 40g / m2 non-woven fabric. 20g / m2 non-woven fabric covering the obvious warming effect, the ground temperature than the uncovered control increased 0.8 ~ 2.6 ℃, 5 ~ 20cm soil regardless of sunny, rainy days have warming trend, especially in 5cm soil layer Increased temperature of 1.8 ℃. Floating surface coverage of the growth of baikai cabbage has a significant role in promoting. The yield is obvious, the law is 30g / m2 non-woven> 20g / m2 non-woven> 25g / m2 non-woven> 40g / m2 non-woven> SZW10 silver shade net, Foot yellow cabbage.
