前言 地膜复盖花生栽培技术,由于增产幅度大,经济效益好,栽培面积扩大很快,但是残膜对土壤、饲料、环境的污染,对下茬作物种子发芽、根系发育都带来了影响,长期下去势必造成公害。我们于82、83、84三年对大连塑料研究所边研制。边试验、边改进的不同使用周期光解膜进行了试验,84年提供的光解膜已基本定型,故进行多点试验及示范,以期尽快用于生产。 Pretreatment of mulching with plastic film covered peanut cultivation, due to large yield, good economic efficiency, cultivation area expanded rapidly, but the residual film on the soil, feed, environmental pollution, the next crop seed germination, root development have had an impact, Long-term is bound to cause public nuisance. We 82,83,84 three years to Dalian Institute of Plastics edge research and development. While testing, photofilm film was tested under different cycles of improvement. The photolysis film provided in 1984 has been basically finalized. Therefore, multi-point experiments and demonstrations were conducted in order to be used for production as soon as possible.
