Certain plastic mulches also act as a barrier to keep methyl bromide, both a powerful fumigant and ozone depleter, in the soil. Crops grow through slits or holes in thin plastic sheeting. Plastic mulch is often used in conjunction with drip irrigation. Some research has been done using different colors of mulch to affect crop growth. This method is predominant in large-scale vegetable growing, with millions of acres cultivated under plastic mulch worldwide each year. Disposal of plastic mulch is cited as an environmental problem; however, technologies exist to provide for the recycling of used/disposed plastic mulch into viable plastic resins for re-use in the plastics manufacturing industry.〔(Plastic mulch film recycling process ) Agricultural plastics recycling website, accessed 07.03.08〕 ==History== The idea of using polyethylene film as mulch in plant production saw its beginnings in the mid-1950s. Dr. Emery M. Emmert of the University of Kentucky was one of the first to recognize the benefits of using LDPE (low density polyethylene) and HDPE (high density polyethylene) film as mulch in vegetable production. His work in this area was done at the University of Kentucky. Dr. Emmert also wrote on other topics such as the use of plastic for greenhouses instead of glass and plastic in field high tunnels. Today, Dr. Emmert is considered the "father of plastic greenhouses". He was jokingly also called the "plastic surgeon" due to his use of plastic instead of glass for greenhouses and his use of clear and black plastic as mulch in vegetable production. Approximately of agricultural land utilize polyethylene mulch and similar row covers for crop production in the world. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plastic mulch」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
