不同保温材料覆盖对戈壁地葡萄越冬温度的影响

Effects of Different Insulation Materials for Covering Soil on Gobi Ground Grape Over-Wintering

为筛选葡萄越冬覆盖材料，采用Microlabe Lite型U盘温度记录仪对不同覆盖材料处理葡萄越冬后的根系周围各层（0、30、60 cm）土壤温度进行了观测，研究各处理对葡萄根系周围土层温度的影响。结果表明，各种覆盖处理对葡萄越冬期间根系周围0~60 cm土层温度影响较大；黑胶棉、大棚棉被处理后可减少≤-5℃低温持续的天数；在戈壁地上采用黑胶棉处理后可使地下0~60 cm处的温度提高1.74~13.59℃，保温效果明显，能使葡萄安全越冬。

To screen the special covering materials for grapes over-wintering, the grapes were treated with two different covering materials to study the effect of each treatment on soil temperature at different depth through the observation of soil temperature at 0, 30, 60 cm under soil around the roots of grapesby Microlabe Lite U disk temperature logger. The results showed that each treatment had significant insulation effect on soil temperature at 0~60 cm depth and effectively decreased the days of low temperature （≤-5℃）. The underground temperature at 0~60 cm were increased 1.74~13.59℃ by covering vinyl cotton in the gobi ground effectively ensuring the grape over-winter.
