| Abstract: |
| Based on the long term field experiment in inland river irrigation area,the effect of different tillage treatments on winter-wheat farmland soil water and temperature was investigated.The result showed that the average soil water content in 0～150 cm layer of no-tillage with straw retention(NTS) was 0.21%,0.23% higher than that of no-tillage(NT) and conventional tillage(T) respectively during the stage of winter-wheat turning green to maturating.The average soil water content in 0～150 cm layer after winter-wheat was harvested were showed as follows: NTS>NT>>T.The soil temperature in 0～25 cm layer of NTS was lower than that of NT and T in sunny day and cloudy day during the stage of winter-wheat turning green to maturating.The average soil temperature of NTS was 2.8℃ and 2.6℃ lower than that of T.The NTS could steady the soil temperature.There was significantly negative relationship between soil water content and soil temperature. |
