摘　　要：以酿酒葡萄"赤霞珠"为试材,采用不同覆盖方法,研究了葡萄越冬期间枝蔓、根系附近土壤温度及含水量的变化及对翌年葡萄生长特性和果实品质的影响。结果表明:越冬期温度最低时,化纤毯加覆土与聚苯乙烯保温被处理,枝蔓附近土壤温度较覆土处理分别提高了3、0.8℃,根系20cm附近土壤温度较覆土处理分别提高了1.9、1.4℃;化纤毯加覆土处理枝蔓附近土壤含水量较覆土处理提高了1.7%;化纤毯加覆土与聚苯乙烯保温被处理,根系20cm附近土壤含水量较覆土处理分别提高了3.5%、1.5%;化纤毯加覆土覆盖处理"赤霞珠"葡萄翌年萌芽率最高,单果质量最大,为1.35g,可溶性糖含量为21.33%,总酸含量为8.09%。说明化纤毯加覆土覆盖对"赤霞珠"葡萄越冬防寒效果最好。Taking ‘Cabernet Sauvignon＇grape as test material,the soil temperature and water content near the grapes roots and vines with different mulching methods over winter and grapes growth characteristics,fruit quality in next year were studied.The results showed that when it was minimum temperature,soil temperature near the dendrite,fiber blanket with covering soil,polystyrene blankets increased 3℃,0.8℃compared with covering soil.Near root 20 cm soil temperature,fiber blanket and covering soil,polystyrene blankets increased 1.9℃,1.4℃compared with covering soil.Soil moisture near the dendrite,fiber blanket with covering soil increased 1.7% compared with covering soil.Near root20 cm soil moisture,fiber blanket with covering soil,polystyrene blankets increased 3.5%,1.5%compared with covering soil.Fiber blanket with covering soil rate of germination was the highest.Fruit weight was up to 1.35 g,soluble sugar content was 21.33%,total acid content was 8.09%,fiber blanket with covering soil was the best method in cold winter for‘Cabernet Sauvignon＇grape.
