摘  要：
2001～2002年连续两年在方山县马坊镇对马铃薯覆膜后气候生态效应进行了试验研究,结果表明,地膜覆盖有明显的增温效应,苗期增温效应最为明显,随着马铃薯的生长发育,覆盖增温效应逐渐降低;表层增温显著,且随土层向下延伸,增温趋向递减;缩短了生育期,提早成熟上市;拓展了品种推广领域,打破了高寒冷凉区不能种晚熟品种的禁区;增产率达25.63%～36.05%,对提高高寒冷凉区马铃薯产量效益有重要的意义。

摘  要：
Insufficient effective cumulative temperature restricts potato production in high latitude and cold area. A research on climate ecological effect in planting potato under a plastic-film has been done in Fangshan County from 2001 to 2002. The result shows that an increased temperature under plastic cover has got obvious effect during the young plant growing. Along with the growth of potato, the increased temperature effect is reducing gradually;Meanwhile,the temperate in the surface layer increases apparently. With its temperature penetrated into the layer, the trend of the increased temperature effect reduces successively. This technique shortens the growth period and potatoes go to market earlier. The technology extend the potato production into high latitude cold area. The output profit has been raised between 25.63% and 36.05% Consequently, it is of great importance to raise the potato output and income in high latitude cold area.
