在幼龄胶林行间种植匍匐豆科覆盖能保土、保水、保肥、改良土壤结构。更重要的是固氮的豆科覆盖作物能把大量的氮归回土壤,从而提高土壤肥力,促进胶树生长,缩短胶树非生产期。马来西亚研究所13年的试验表明:种植匍匐豆科复盖的林段比不种的提前一年开割,每亩可多收入相当于71元的干胶;不种的林段要比多年种的林段,每亩多施233.3——286.7公斤硫酸铵,折合人民币计算,复盖林段每亩可节约51—62元的肥料费。一进
Creeping young legumes in the forest between rows of legume coverage can soil, water, fertilizer, improve the soil structure. More importantly, nitrogen-fixing legume cover crops return large amounts of nitrogen to the soil, improving soil fertility, promoting gum tree growth and shortening the non-productive period of the gum tree. Malaysia Institute for 13 years of tests showed that: planting creeping legume covered forest section than a year earlier cut open, per acre can be equivalent to 71 yuan more than the income of the dry adhesive; not species of forest than multi-year Of the forest, more than 233.3--286.7 kg per acre ammonium sulfate, equivalent to RMB calculation, cover the forest can save 51-62 yuan per mu fertilizer fee.
