| 摘 要： | 对黄土高原渭北地区旱作生草苹果园3～10月0～100 cm土层土壤水分观测结果表明: 在0～40 cm土层牧草与果树存在水分竞争, 但生草对40～80 cm土层水分具有调蓄作用, 生草种类不同, 对土壤贮水增减量的影响存在差异, 其影响主要发生在春季与秋季, 在降水丰水年影响较小, 但在降水欠水年生草对果园土壤贮水影响较大。

| Abstract: | Analysis on soil moisture in 0-100 cm soil layer in nonirrigated apple orchard in Weibei areas during March to October in 2003 and 2004 year showed that water content competition existed between herbage and apple in 0-40 cm soil layer. But planting herbage had function of retain soil water content to 40-80 cm soil layer. With different kind of herbage and different water consumption of different kind of herbage, the increasing and decrease of soil moisture storage was different in planting herbage areas, this occurred mainly in spring and in autumn. In the abundance of rainfall, planting herbage impacted less on soil moisture storage. But impacted more on soil water storage in the year of drought. |
