摘　　要：为查明关中平原中部地区猕猴桃园不同季节不同树龄的土壤含水量变化状况,在2010年春季和夏季对周至县仰天村的猕猴桃果园进行采样分析。结果表明,3～4龄和8～9龄果园土层含水量从表层向下呈高-低-高的变化趋势,15～16龄果园土层含水量从表层向下呈低-高-高的变化趋势。春季8～9龄猕猴桃林地10～400 cm土层含水量变化趋势为低-高,与夏季同等树龄土层含水量的变化趋势相反。不论在夏季还是春季不同深度土层的含水量均大于土壤干层的理论值12%,未形成土壤干层。其主要原因有降水强度差异;植物不同生长期和不同季节的需水要求差异;不同类型植物对土壤含水量的需求差异;猕猴桃园的选址等。In order to investigate the change of the soil moisture content of the kiwi fruit orchards at different ages and seasons in the middle Guanzhong plain,a sampling analysis of the kiwi fruit orchards was taken in Yangtian, Zhouzhi in spring and summer,2010. The resuhs showed that the soil moisture content at 3 to 4 and 8 to 9 age of the orchards appeared a high-low-high tendency down from the surface,while 15 to 16 a- ges orchards appeared a low-high-high tendency down from the surface. Opposite to summer,the soil moisture content of the kiwi fruit orchards at 8 to 9 age showed a tendency of low-high from 10 cm to 400 cm in spring. Both in summer and spring,the soil moisture contents at different depth were all higher than the theoretical value. The major reasons were, the distinct of the precipitation intensity, and the different demand of water for the plants in different growing periods, seasons and types. The site selection of the orchards influenced the water content ,too.
