摘　　要：选用6种全生物降解地膜和1种普通地膜,研究不同全生物降解地膜与普通地膜的上机性能、增温保墒性能及对作物生长、产量的影响。结果表明:6种全生物降解地膜上机性能良好,均能满足机械化覆膜操作要求;6种全生物降解地膜增温保墒性能均能达到普通地膜水平,其中以来自上海弘睿生物科技有限公司、上海巴斯夫塑料有限公司、兰州鑫银环塑料制品有限公司的全生物降解地膜效果较优;6种全生物降解地膜均能提高作物产量,以来自广东金发科技股份有限公司、海南威盛华泰环保科技公司、兰州鑫银环塑料制品有限公司的全生物降解地膜增产效果较为明显。综合来看,来自广东金发科技股份有限公司、海南威盛华泰环保科技公司、兰州鑫银环塑料制品有限公司的全生物降解地膜具备良好的增温保墒性能,且在提高水稻旱作产量方面具有较好的效果,值得在干旱半干旱地区水稻旱作栽培中推广应用。Six kinds of fully biodegradable plastic films and one kind of ordinary plastic film were selected to study the mechanical performance, temperature and moisture increasing performance and as well as their effects on crop growth and yield. The results showed that the six kinds of fully biodegradable plastic film had good performance and could meet the mechanized mulching operation;the temperature and moisture increasing performance of six kinds of fully biodegradable plastic films could reach the level of ordinary plastic film, among which, the fully biodegradable plastic film from Shanghai Hongrui Biotechnology Co., Ltd., Shanghai BASF Plastic Co., Ltd. and Lanzhou Xinyinhuan Plastic Products Co., Ltd. had the better effect;six kinds of fully biodegradable plastic films could increase crop yield, and the yield increasing effect of fully biodegradable plastic films from Guangdong Jinfa Technology Co., Ltd., Hainan Weisheng Huatai Environmental Protection Technology Co., Ltd. and Lanzhou Xinyinhuan Plastic Products Co., Ltd. was more obvious. On the whole, the fully biodegradable plastic films from Guangdong Jinfa Technology Co., Ltd., Hainan Weisheng Huatai Environmental Protection Technology Co., Ltd. and Lanzhou Xinyinhuan Plastic Products Co., Ltd. had good performance of increasing temperature and preserving moisture, and good effect in improving the dryland rice yield, which is worthy of popularization and application in dryland cultivation of rice in arid and semi-arid areas.
