摘　　要：以设施冷棚二年生"突尼斯"软籽石榴为试材,采用3种不同防寒措施处理软籽石榴植株的方法,研究了不同防寒措施下软籽石榴根系附近土壤温度、植株生长情况及渗透调节物质的变化,以期筛选出较好的防寒措施。结果表明:在地温最低阶段,3个处理软籽石榴根系附近10 cm土层温度均高于对照;秸秆+棉被和秸秆+黑膜处理下的植株死亡率最低,覆土和秸秆+棉被处理后枝条有一定霉烂,秸秆+棉被和秸秆+黑膜处理的新梢抽干率最低;相对电导率和脯氨酸含量变化与综合评价的结果一致,可作为有效评价软籽石榴抗寒性的标准。综合分析几种防寒措施的防护效果优劣依次为秸秆+黑膜>秸秆+棉被>覆土>对照。Two-year-old‘Tunisia’soft seed pomegranate in cold shed was used as material,the changes of soil temperature,plant growth and osmotic regulation substances near the root of soft seed pomegranate were studied by using three kinds of cold prevention measures.In order to screen out the better cold prevention measures.The rsults showed that at the lowest temperature,the soil temperature at 10 cm depth near the roots of the three treated soft seed pomegranate was higher than that of the control group;the death rate of plants treated with straw+cotton quilt and straw+black film was the lowest,the branches would be mildewed after the treatment of soil covering and straw cotton quilt,straw+cotton quilt and straw+black film treatment of the new shoot draining rate was lowest;the changes of relative conductivity and proline content were consistent with the results of comprehensive evaluation and it can be used as an effective criterion to evaluate the cold resistance of soft seed pomegranate.Based on the comprehensive analysis,the protective effects of several cold prevention measures were ranked as follows,straw+black film>straw+quilt>turns the soil>control.
