马来西亚的植胶地普遍缺磷,大多数植胶地土壤似乎都具有较强的固定无效态磷的能力,因此必须寻求一种既能促进胶树生长又能保持产量的施磷方法。在橡胶植后初期,植株只能长出有限的根系,这时施用磷肥最重要的是必须施在树根容易吸收和迅速利用的部位。现已证实, Most of the plasticized soils in Malaysia seem to have a strong ability to immobilize ineffective phosphorus. Therefore, it is necessary to find a phosphorus-applying method that can both promote the growth of gum trees and maintain the yield. In the early stages of rubber planting, the plant can only grow a limited root system, then the most important application of phosphate fertilizer must be applied to the roots easily absorbed and rapid use of the site. It has been confirmed,
