中文摘要:
      西北黄土高原,光照丰富,雨热同期.实施旱作带田一膜两用技术,可增温2-5℃,节水30-40mm以上,调水70%左右.热量利用率高达0.987,降水利用效率15.15kg/(mm·hm2),气候生产力利用指数0.49.增产效益明显,变作物一年一作为一年两作,总产可达8250-9000kg/hm2,比单作增产45%以上.
英文摘要:
      Loess Plateau of northwest,illumination is abundant.Rain and heat is in a period.Microclimate of farmland have the obvious effect while a technology of plastic sheet mulching strip land with rainfed was carried out.The ground temperature increase 2-5℃,water saving 30-40mm.It is reached 70% or so the regulation of water with each other.Heat use efficiency is 0.99,precipitation is 15.15kg/(mm·hm2) the climate produce potential exponent is 0.49.The increase produce have the obvious effect changing one into two cultivation a year.Total output attained 8250-9000kg/hm2,increased yield over 45% ocomparision with the monocultivation.
