| 摘 要： | 针对东北地区常见的4种耕作方式(留茬覆盖、留茬无覆盖、旋耕和翻耕起垄),测定了玉米田土壤温度的动态变化.结果表明:留茬覆盖处理土壤温度较低,但并未低于出苗的最低界限温度;由于土壤含水量较高,出苗效果良好,秸秆全量还田,有利于土壤肥力的恢复与提高.

| Abstract: | Dynamic change of soil temperature in corn field in the Northeast under four kinds of tillage methods(stubble with cover,stubble without cover,rotary tillage,plowing and ridging)were determined,the results showed that the soil temperature of stubble with cover was lower,but it was higher than the lowest limit temperature for emergence,and emergence was good because of higher soil water content,total returning of crop straw was beneficial to recover and improve the soil fertility. |

| Keywords: | tillage methods soil temperature stubble with cover |
