摘    要:利用土壤水动力学原理和水量平衡计算方法,在5年生沙地葡萄园,通过建立观测场,在群体条件下研究葡萄需水规律。观测场埋设中子管和负压计,监测水分动态和水势变化,求出地下水位值。得出了群体条件葡萄需水量为644.5mm。春季(3-5月)需水量为126.5mm,夏季(6-8月)为343.8mm,秋季(9-11月)为142.7mm,冬季(12月、1月、2月)为31.5mm。埋土防寒期需水量最小为0.5mm/d,6月需水量最大为4.2mm/d。生长期平均需水量为2.6mm/d。

关 键 词:沙地  葡萄  水量平衡  需水量

Abstract:The law of water requirement under population conditions in 5- year vineyard on sandy land was studied by soil water dynamics principle and water equilibrium method through observation space.For monitoring water dynamics and water potentials change,neutron tube and tensiometer were embedded at observation space.The groundwater levels were obtained.The total water requirement of grape is 644.5 mm under population condition,in Spring (March,April and May) there are 126.5 mm,343.8 mm in Summer(June,July and August),142.7 mm in Autumn(September,October and November),and 31.5 mm in winter(December,January and February).The minimum of water requirement was measured in burying soil period through winter,that was 0.5 mm/d,and the maximum of 4.2 mm/d was in June.The average water requirement in growing period was 2.6 mm/d.
Keywords:sandy land  grape  water equilibrium  water requirement
