摘    要:
利用定位实时监测和数学模拟的方法,在中国北方典型的土壤水蚀风蚀区神木县选择试点,对免耕、秸秆覆盖、地膜覆盖等6种不同耕作措施下不同耕作层的地温和土壤含水量进行了连续测定.结果表明:起垄地膜覆盖提高地温的效果最好,在特定时间不同深度或同一深度不同时间的土壤温度都以起垄地膜覆盖最高,其在观测期内的总积温比对照高10% ;而秸秆覆盖在各个测定深度上的地温都低于对照,其在观测期内的总积温比对照低2.3%.

关 键 词:黄土高原  耕作措施  土壤水分  地温

Abstract:
By using real-time monitoring and positioning mathematical simulation methods and selecting the typical water and wind erosion area in Shenmu in north China as the testing site,continuous determination was conducted of the ground temperature and soil moisture on different depths among six measures such as no-tillage,straw mulching and plastic film mulching.The results showed that: ridge plastic film mulching improves the ground temperature best,either for specific time at different depths or for the same de...
Keywords:Loess Plateau  cultivation measure  soil moisture  gr ound temperature  effect
