摘要
试验以平地栽植为对照,研究了西北沙地深沟栽植葡萄在干旱胁迫下的根域耗水规律和需水特性。结果表明,浇水后进行控水,深沟栽植下葡萄根域土壤水分日蒸发量低于平栽对照,土壤相对含水量高于平栽对照,日蒸散量低于平栽对照;深沟栽植下葡萄的年耗水量和年需浇水量均低于平栽对照。深沟栽植模式有利于保持水分,比平栽模式具有明显的节水作用,从而实现节水灌溉。
With the flat planting as comparison, the experiment was studied root field water consumption and water requirement characteristics of grape in the deep trench planting under drought stress in the northwest sandy area. The results were as follows： in the deep trench planting, they were lower than flat planting in the root field soil moisture evaporation of grape and daily evapotranspiration, meanwhile soil relative water content was higher than flat planting after watering; the deep groove planting saved more water than fiat planting in annual water consumption and annual watering aquirement. The above results showed that the deep trench planting pattern was beneficial to hold water and had obviously water-saving effect for the flat planting, realizing water-saving irrigation.
