摘要
针对一年两熟干旱半干旱地区的具体特点,对具有不同高度麦茬的免耕田土壤含水率及土壤地温的变化进行了实验研究。实验结果表明:免耕麦茬田留有麦茬可以提高土壤中水分的含量,减少土壤中水分蒸发的速率。麦茬可以提高夜间土壤的温度,也可降低土壤在白天的地温。
Soil moisture and temperature changes in arid and semi-arid double cropping areas were studied. High wheat stubble can increase soil moisture and decrease water loss in soil. Wheat stubble also can help increase soil temperature after sunset. And it can help to reduce soil temperature in day-time.
