模拟试验表明,平铺5cm对前期的单株鲜重有明显影响,双侧20cm对后期的单株鲜重有明显影响;各处理的单株铃数和籽棉产量均比对照显著降低。地膜在农业上应用带来了“白色革命”,其增产作用已得到到了充分肯定。据资料报道,1990年全国地膜覆盖棉田面积达到1294万亩。近期许多研究者报道了废地膜带来的危害,但却没有直观确切的数据。笔者通过模拟试验,探讨了废地膜对棉花的影响。 The simulation test showed that the 5 cm tiling had a significant effect on the fresh weight of the early stage, and the 20 cm both sides had a significant effect on the fresh weight of the late stage. The bolls per plant and the seed cotton yield were significantly lower than those of the control. Film in agriculture has brought a “white revolution”, its role in increasing production has been fully affirmed. According to statistics, in 1990, the area of ​​plastic film covered cotton reached 12.94 million mu. Recently, many researchers reported the harm caused by waste film, but there is no direct and accurate data. I through the simulation test to explore the impact of waste film on the cotton.
