摘  要:国外保护性耕作技术体系已趋完善,我国平作区的保护性耕作技术已得到大面积推广应用。为研究垄作区保护性耕作技术体系,提出了玉米产区和杂粮产区的一深两免耕作模式。通过与传统垄作耕作对比试验,其土壤含水量高于传统耕作条件下的含水量;平均地温在8:00时比传统耕作高,而在14:00和20:00时比传统耕作低,有利于作物生长;作物产量高于传统垄作区,实现了农民增收节支。Foreign conservation tillage technology system has almost gradually completed, formation farming areas of conservation tillage technology has been widely applied in China. In order to study lung farming areas of conservation tillage technology system, put forward a corn - producing areas and grains producing a deep two - mode - free farming. With the traditional ridge cultivation test analysis, soil moisture is higher than traditional farming under the conditions of water content. 8:00, when the average ground temperature than traditional farming high and at 14:00 and 20:00 than traditional farming low, is conducive to crop growth. Crop yields than traditional ridge area, implementation of the peasants increase revenue and reduce expenditure.

关 键 词:保护性耕作 一深两免耕作模式 免耕覆盖 土壤含水率
