摘要
利用普通塑料薄膜和光生态塑料薄膜两种覆盖材料为试验材料,研究它们对大棚内若干环境指标及蔬菜生长发育的影响。结果表明:光生态塑料薄膜比普通塑料薄膜具有更好的透光性和增温性,因此可以促进蔬菜产量的形成。
Common plastic film and light-ecology plastic film were used as experiment materials to research the influence on vegetable development in plastic film shed. The results showed that light-ecology plastic film compared to common plastic film had the better light transmittance and protective temperature, at the same time, light-ecology plastic film could increase vegetable yield.
