一、试验目的通过棉田覆盖不同厚度地膜试验,分析其对作物出苗和产量的影响,比较使用不同厚度地膜的经济效益,降低地膜使用成本、有效控制地膜残留污染,为地膜生产与推广提供科学依据。二、试验设计试验田设在塔里木乡园艺村。试验设4个处理,分别为4种厚度聚乙烯塑料地膜。处理A,地膜厚度0.006毫米;处理B,地膜厚度0.008毫米;处理C,地膜厚度0.010毫米;处理D,地膜厚度0.012毫米。每小区面积360米2(30米×12米)。
First, the purpose of the experiment Cotton fields covered with different thickness of the film test to analyze the impact of crop emergence and yield, the use of different thickness of the film compared to the economic benefits and reduce the cost of the use of plastic film, Film Residual pollution control effectively provide a scientific basis for the production and promotion of plastic film . Second, experimental design Experimental field is located in Tarim Township Horticultural Village. Test set up four treatments, respectively, four kinds of thickness polyethylene plastic film. Treatment A, the thickness of the film 0.006 mm; treatment B, the thickness of the film 0.008 mm; treatment C, the thickness of the film 0.010 mm; treatment D, film thickness 0.012 mm. Each plot area of 360 m 2 (30 m × 12 m).
