摘    要:目的]为葡萄的安全越冬提供参考。方法]运用MicroLite-U盘型温度记录仪和直尺记录空气温度、地温和积雪厚度,研究不同覆盖方式和不同的积雪厚度下地温的变化规律。结果]葡萄在不同覆盖条件下地温变化均呈先降低后升高的曲线。在正常情况下,埋土越冬期间地表极端最冷温度稍微低于覆被,两者相差0.45℃左右;而在4月份温度上升时覆被温度明显高于埋土,两者相差4.56℃左右。在该试验条件下,10 cm的积雪厚度可增加地表温度4~6℃。结论]葡萄越冬期间埋土与覆被相比,地温变化的总体趋势是一致的,而覆被地温比较稳定,温度明显高于埋土。另外,积雪厚度的增加明显延缓了地温的降低,保护了葡萄根系不受冻害。

Abstract:Objective] To provide reference for the overwintering safety of grape.Method] The air temperature,ground temperature and snow depth were recorded by microLite-U temperature recorder and ruler to study the effects of different covering methods and different snow depths on the change of ground surface temperature.Result] The ground surface temperature increased at first and decreased subsequently under different covering methods.Under normal condition,the lowest buried surface temperature was slightly lower than the lowest cover surface temperature by about 0.45 ℃ during overwintering period;but when the temperature rose in April,the cover temperature was significantly higher than the cover temperature by about 4.56 ℃.Under the same experimental conditions,10cm snow depth could increase the ground temperature about 4-6 ℃.Conclusion] The overall trend of buried ground temperature was basically in consistency with that of cover ground temperature during the overwintering period of grapes,but the cover ground surface temperature was relatively stable and higher than buried.In addition,the increased snow depth significantly delayed the reduction in ground surface temperature and protected grape roots from frost damage.
Keywords:Grape  Snow depth  Cover  Buried
