不同覆盖措施对枣园土壤水分和温度的影响

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。

Effects of Different Mulching Measures on Orchard Soil Moisture and Temperature

In order to provide scientific basis for the planting red dates of oasis in Xinjiang,the effects of different coverage measures on soil moisture and temperature in jujube garden were studied. In the different cultivation measures,five years of Jun jujube orchard soil moisture and temperature were measured. The results showed that the average soil moisture content of 0-100 cm from high to low were as follows,rotary tillage straw mulching rotary tillage soil no tillage bare land rotary tillage rotary. The average soil temperature of 0 - 25 cm were,rotary film mulching tillage no tillage bare naked. The rotary tillage with straw cover and tillage mulching can maintain soil moisture,rotary tillage and rotary tillage soil mulching can effectively improve soil temperature,rotary tillage with straw cover prevents soil temperature increasing high,while no tillage has little effects.
