摘要
通过 2年的田间试验资料 ,研究了夏玉米免耕蓄水保墒、节水和提高水分生产率的效果 ,为探求最大限度地利用田间降雨和减少土壤水分的无效蒸发。
A field experiment was conducted to study the water saving and water use efficiency improving effects of non tillage cultivation in corn in two years. Research results show that not tillage is an effective method of raising rainfall use rate, reducing soil surface evaporation, and improving water use efficiency.
