摘　　要：研究了传统耕作、玉米原垄留茬耕作、玉米原垄留茬全覆盖、玉米留茬条带覆盖、浅松覆盖和深松覆盖6种耕作方式下土壤含水率、棵间蒸发量和地温的变化。结果表明,条带覆盖对大豆不同生育期土壤剖面含水率影响最大;其他耕作方式对棵间蒸发的抑制作用均小于传统耕作;日平均地温在苗期变化明显;保护性耕作对日平均地温影响较大,传统耕作最高,留茬全覆盖最低。The changes of soil water content,evaporation between plants and soil temperature were studied under the six different tillage patterns（traditional farming,no-tillage with maize stubble covering,entirely-tillage with maize stubble complete covering,strip-tillage with maize stubble,surface-pulverize covering and deep-pulverize covering）.The results showed that the influence of strip covering on soil water content in profile was the most obvious;The inhibitory effect of evaporation between plants under others tillage patterns was weaken than that under traditional farming;The daily average temperature in seeding stage changed significantly.Conservation tillage had a great impact on the daily average temperature,and the effect of traditional farming on the daily average temperature was the highest while the effect of entirelytillage with stubble complete covering on the daily average temperature was the lowest.
