摘　　要：以酿酒葡萄"赤霞珠"为试材,采用覆土、化纤毯加覆土、聚苯乙烯保温被3种覆盖方式,测定越冬期间枝蔓的逆境生理生化指标的变化,选出对葡萄越冬性及生长最佳、最有益的覆盖方式。结果表明:越冬期间在较冷的1、2月,枝蔓逆境生理指标的束缚水与自由水的比值变化为化纤毯加覆土>聚苯乙烯保温被>覆土;对电解质渗出率与温度相关性研究发现,电解质渗出率与温度呈负相关,在2015年1月1日取样枝蔓电解质渗出率,覆土>聚苯乙烯保温被>化纤毯加覆土;不同处理丙二醛(MDA)含量变化为,化纤毯处理越冬前后枝蔓MDA含量基本无变化,覆土处理越冬后枝蔓MDA增加0.002 1μmol·g^(-1),聚苯乙烯保温被则增加了0.005 3μmol·g^(-1);在越冬期间温度较低的1、2月,化纤毯加覆土处理枝蔓脯氨酸含量较覆土与聚苯乙烯保温被分别增加0.000 8、0.001 1μg·g^(-1)。＇Cabernet Sauvignon＇ was used as the test material. Three treatments which were covering soil, polystyrene blankets, fiber blanket＋covering soil were conducted. Physiological and biochemical indexes stress changes were determined, for selecting the best covering way during the winter. The results showed that, physiological parameters of dendrites indicates was that, the ratio of bound water and free water in January and February was that fiber blanket-covering soil〉polystyrene blankets〉covering soil,and electrolyte leakage rate was negatively correlated with temperature. Electrolyte leakage rate was covering soil〉polystyrene blankets〉fiber blanket＋covering soil on January 1^th ,2015;the MDA that fiber blanket＋covering soil content of dendrite was almost unchanged. The MDA of covering soil increased 0. 002 1μmol·g^-1 after winter. Polystyrene blankets increased by 0. 005 3 μmol·g^-1;the dendrite proline of the treatment of fiber blanket＋covering soil compared with polystyrene blankets,covering soil increased 0. 000 8μmol·g^-1 ,0. 001 1μmol·g^-1 in January.
