在胶园中种植豆科覆盖作物,可以防止土壤流失,并能改良土壤的理化性能。豆科覆盖作物的效果比自然萌生植物或禾本科覆盖植物的好。建立豆科覆盖可改善胶树幼龄期的生长,使产量增加20％,再生皮明显增厚。但是,幼龄胶树与活覆盖对水分和矿质元素有竞争,因此,必须在幼树周围保持一块无植被的空地。 Planting leguminous cover crops in rubber plantations prevents soil loss and improves physical and chemical properties of the soil. Leguminous crops cover plants better than naturally-primed plants or grass-covered plants. The establishment of leguminous cover can improve the growth of rubber tree juvenile stage, so that the output increased by 20%, significantly increased regenerative skin. However, young gum trees and live coverings compete for moisture and mineral elements, and therefore, a vegetated area must be maintained around the saplings.
