Based on testing new type units of winter protection for wine grape, instead of burying earth soft which is traditional measure for cold prevention in winter, we studied influence of soil temperature on grape roots （Cabernet Sauvignon） by ecotype arch-tile units. Result showed that soil temperatures dealing with ecotype arch-tile units were higher than those with burying earth soil treatment, but not significant. In the spring, mortality of branches and tendrils with arch-tile units was slightly higher than that with burying earth soil treatment; Differences did not reach a significant level, but fracture rate of new shoots with arch-tile units is significantly lower than that with burying earth soil treatment. Therefore, under the experimental conditions, the effects of winter protection by ecotype arch-tile units equal to that of burying earth soil, ecotype arch-tile units were able to make over-wintering Cabernet grapes live safely.%为了探索能替代葡萄冬季埋土防寒措施的新型防寒装置，本试验以赤霞珠葡萄为材料，研究生态型弓瓦防寒装置对葡萄根系土层温度的影响，结果表明，弓瓦防寒装置处理的各土层温度高于埋土处理，但是差异不显著．在春季，弓瓦处理的枝蔓死亡率略高于埋土处理；差异没有达到显著水平，但是新梢折断率显著低于埋土处理，因此，在试验条件下，生态型弓瓦防寒装置的防寒效果和埋土防寒措施相当，可以使赤霞珠葡萄安全越冬．
