摘　　要：为探索宁海地区全生物降解地膜替代普通地膜对马铃薯产量及经济效益的影响,以黑白双色全生物降解地膜、PE白色地膜、PE黑色地膜为处理,裸地无膜为对照(CK),开展马铃薯种植比较试验。结果表明,产量方面,黑白色双色全生物降解地膜>PE白色地膜>PE黑色地膜>裸地无膜;经济效益方面,黑白色双色全生物降解地膜>PE白色地膜>裸地无膜>PE黑色地膜。因此,认为用黑白双色全生物降解膜替代普通地膜可有效提高马铃薯产量及经济效益。In order to explore the effect of fully biodegradable plastic film mulching instead of ordinary plastic film mulching on the yield and economic benefits of potato in Ninghai area,the comparative test of potato was carried out with black-white match color fully biodegradable film,PE white plastic film and PE black plastic film as treatments,and no film mulching as control.The results showed that in terms of yield,black-white match color fully biodegradable film>PE white plastic film>PE black plastic film>no film mulching;in terms of economic benefits,lack-white match color fully biodegradable film>PE white plastic film>no film mulching>PE black plastic film.Therefore,it was considered that the black-white match color fully biodegradable film can effectively improve the yield and economic benefits of potato instead of ordinary plastic film.
