| Abstract: |
| Experiments were conducted to study soil temperature in dry areas of west Heilongjiang field under four cultivation treatments and inter-tillage.The result show that:No tillage and loosening method regulate soil temperature effectively.They increase soil temperature by 0.5～1℃ in the morning when air temperature was low, but reduced the rate of temperature increment in the afternoon when temperature was higher.Inter-tillage increases soil temperature by 1～2℃ when temperature is high, but also increases the rate of temperature decrement.Therefore no tillage and loosening method without inter-tillage could keep the stability of soil temperature and is beneficial for the crop growth in dry areas of west Heilongjiang, while rotary tillage and inter-tillage are unsuitable for farming in the area. |
