摘要
对塑料大棚多层覆盖、双层大棚内加小拱棚和双层大棚内加地膜等三种覆盖形式的种植环境进行了系统试验研究，其研究结果可作为采用塑料大棚多种覆盖方式的依据．
An experimental study has been carried out to survey the planting environment within the double-layered plastic greenhouse,small vault cover as well as ground plastic film cover under the double-layered greenhouse. The result provides a scientific basis for application of multi-lay-ered greenhouse to plant growth.
