| 摘 要： | 在老龄果园套种优良牧草鸭等（Dactylisglomerata）和鹰嘴紫云英（Astragaluscicer）。经3年试验，研究结果表明，果园套种鸭茅和鹰嘴紫云荚，具有蓄水保墒，提高土壤肥力，促进果树生长发育，增加果实产量，改善果实品质等明显效应。尤其鸭茅具有耐前性强，覆盖度大，生物学量高，再生性强等优点，且易于栽培，可在老龄果园中大面积推广。

| Abstract: | Intercropping cocksfoot grass (Dactylis) and cicer milkvetch (Astragalus cicer) in aging orchard has been studied for 3 years. The results show that intercropping cocksfoot grass and cicer milkvetch in the orchard can retain water, preserved soil moisture, raised soil fertility, promoted tree growth. Especially, cocksfoot has many adventages,such as strong shade－ tolerance, large coverage, high biomass, strong regrowth and easy cultivation. Therefore, it can be extensively planted in aging orchards. |
