摘要/Abstract

摘要： 研究葡萄园生草对土壤水分影响,可为葡萄园生草在半干旱地区的应用和推广提供理论依据。在葡萄园种植多年生白三叶草、紫花苜蓿和高羊茅,采用TRIME-FM时域反射仪对生草葡萄园0～80 cm土层进行土壤水分定位观测,采用环刀法对0～60 cm土层土壤物理性状进行测定。结果表明,生草可改善葡萄园土壤物理性状,使0～60 cm土壤容重平均降低8.5%～9.8%,总孔隙度提高11.5%～13.9%。在不同降水年份,葡萄园行间生草均使土壤含水量降低,在2006及2007年,生草使0～80 cm土层土壤含水量平均降低幅度分别为2.3%～7.5%及10.7%～15.9%,在冬季贮水量不足、春季干旱的年份土壤含水量降低幅度较大。生草种类不同,对土壤贮水量及增减量的影响存在差异,紫花苜蓿区土壤贮水量较低。

Abstract: Soil water content was closely correlated with application and extent of vineyard cover crop in a semiarid area. A permanent inter-row cover crop of Trifolium repens, Medicago sativa, and Festuca arundinacea in a vineyard was compared with clean tillage. Localized observation of soil moisture content in the 0-80 cm layer with TRIME-FM TDR was carried out in the vineyard, and soil physical characteristics of the 0-60 cm layer were investigated using the cutting ring method. After planting grasses, the soil physical characteristics improved, soil bulk density of the 0-60 cm soil layer decreased by 8.5%-9.8%, and total soil porosity increased by 11.5%-13.9%. The soil moisture content of a grass-covered vineyard was considerably reduced in 2006 and 2007 compared with clean tillage and the average soil water content of the 0-80 cm depth was reduced by 2.3%-7.5% and 10.7%-15.9% respectively. The soil water content was severely reduced in a year with spring drought and shortage of soil moisture storage from the previous winter. Soil moisture storage and variation of water storage differed between sward treatments, and the M. sativa treatment had the lowest soil moisture storage.
