摘　　要：通过埋土、缠无纺布、搭小拱棚、覆玉米秸秆、生态棉覆盖及对照(露地越冬)6种技术处理,研究了红莓32号、27号和黑莓58号不同试验处理下的抽条情况。结果表明:不同品种均以生态棉覆盖、搭小拱棚和埋土效果最好,均未有抽条;采用玉米秸覆盖,修剪过的红莓32号,其枝条虽有明显失水,但可正常发芽生长,而红莓27号有明显抽条,抽条率为83.3%;经修剪采用缠绕无纺布,红莓32号平均枝条抽条率为18.4%,红莓27号平均抽条率为81.4%,黑莓58号均未有抽条;同一品种,基径粗(≥0.7cm)的枝条无论是抽条长度还是抽条率,其防抽效果均比基径细(<0.7cm)的要明显,差异显著。The shoots shriveling of raspberry 32#、27# and blackberry 58# was studied under different treatments of burying soil, non-woven fabrics twined, plastics clothcovering, corn stalkcovering, ecology cottoncovering and the control（outdoor wintering）. The result showed that the effects of the three varieties were all the best in the treatments ofecology cottoncovering,arched shed and burying soil,with no shoots shrivelingobserved. When covered by corn stalk and pruned meanwhile,the shoots of raspberry 32# had obviousdehydration phenomenon,but could sprout normally. In the same treatment,raspberry 27#had obviousshoots shriveling,and the rate was 83.3%. when twined by non-woven fabrics and pruned meanwhile,the average shoots shriveling rate of raspberry 32#,raspberry 27# and blackberry 58# were respectively 18.4%,81.4%% and 0. Within the same variety,when the basal diameter of the shoots greater than or equal to 0.7cm,the shoots shriveling protection effects of the shoots were significantly better than that less than 0.7cm,in the respects of both shriveling shoot length and rate.
