摘　　要：为了寻找防止胶东半岛露天蓝莓越冬抽条的最佳覆盖材料，以7种防寒材料为试材，对青岛胶南露天基地2～3年生“蓝丰”进行了覆盖试验，通过抽条率和抽条指数来反映不同覆盖材料的防寒效果。结果表明：“黑膜”与“膜十三帧遮阳网”的抽条率和抽条指数最低，防寒效果最佳，但从成本以及资源利用角度看，最适合胶南露天蓝莓越冬的最优覆盖材料为“膜十三帧遮阳网”。Seven cover materials were used to find the optimal cover material for protecting the two or three-year-old blueberry trees from cold damage in winter in Jiaodong peninsula of Qingdao city. After covered with materials, chilling drought injury rate and chilling ＆ drought index of branches in each blueberry tree were counted to determine the effect of protection. The results showed that, the chilling ＆ drought injury rate and chilling ＆ drought index of branches in blueberry trees covered with ＇black film＇ or ＇membrane together with three frame of sun-shade net＇ were lower than those branches in blueberry trees covered with other materials. With the consideration of cost and resource utilization, ＇membrane together with three frame of sun-shade net＇ cold damage in winter in Jiaodong peninsula of Qingdao were optimal cover materials for protecting blueberry trees from city.
