研究不同覆盖措施对枣园土壤水分和温度的影响,旨在为新疆绿洲农业红枣种植提供有力的科学依据。在旋耕覆膜、旋耕秸秆覆盖、旋耕裸地和免耕裸地条件下,对五年骏枣枣园的土壤水分和温度进行测量。在田间管理一致的情况下,0~100cm土壤平均含水量旋耕秸秆覆盖>旋耕覆膜>免耕裸地>旋耕裸地;0~25 cm土壤平均温度旋耕覆膜>旋耕裸地>免耕裸地>旋耕秸秆覆盖。旋耕秸秆覆盖和旋耕覆膜可以保持土壤水分,旋耕覆膜和旋耕裸地能够有效提高土壤温度,旋耕秸秆覆盖阻碍了土壤温度的升高,免耕裸地影响较小。
The effects of different coverage measures on soil water and temperature in jujube orchards were studied to provide a scientific basis for planting jujube in oasis agriculture in Xinjiang. Under the condition of rotary tillage, rotary tillage mulching, rotary tillage bare land and no-tillage bare land, the soil moisture and temperature of Zizyphus Jujuba orchards in the past five years were measured. Under the same field management, the average soil moisture content of 0 ~ 100cm soil cover of rotary tillage> rotary tillage> no tillage> rotary tillage; 0 ~ 25 cm soil average temperature rotary tillage> rotary tillage Ground> No-tillage bare land> Tillage straw mulch. Rotary tillage with straw mulching and rotary tillage could keep soil moisture, rotary tillage and rotary tillage can effectively increase soil temperature. Rotary tillage mulching obstructed the increase of soil temperature and had little effect on no-tillage bare land.
