在肥力较好的砖红壤性土上对橡胶幼树和割胶树的肥料试验表明:幼树施氮磷肥肥效不明显;割胶树单施氮肥对生长和产量有不良影响,亦会加重风、寒等自然灾害。氮磷肥配合施用对生长和产量有一定效果。施优质有机肥亦有效果。初步认为:西双版纳森林、竹林砖红壤性土垦后植胶关键是做好水土保持,在此基础上坚持表土回穴配合适量磷肥作基肥,建立豆科覆盖,幼树期只要利用丰富的林管材料进行扩穴压青改土和死覆盖,可不必再施氮磷钾化肥,仅对肥力较差的林地酌量施用。割胶树每年每株可施有机肥30～50斤、氮肥1～1.5斤,磷肥0.5～0.8斤。重寒害区和个别缺钾林段可增施氯化钾0.3～0.5斤。
Fertilizer experiments on rubber saplings and plastic cutting trees on fertile red brick soil showed that the effect of nitrogen and phosphorus fertilizers on young trees was not obvious. Single nitrogen fertilizer on cut trees had bad effects on growth and yield, Other natural disasters. Nitrogen and phosphate fertilizers with a certain effect on growth and yield. Application of high quality organic fertilizer also has effect. Preliminary thought: Xishuangbanna forest, bamboo forest red clay soil after planting the key is to do a good job of soil and water conservation, on this basis, adhere to the top soil with appropriate amount of phosphate fertilizer as a base fertilizer, the establishment of leguminous cover, young trees as long as the use of rich forest Materials for expanding acupressure to change soil and die to cover, can no longer apply nitrogen, phosphorus and potassium fertilizers, only poor fertility of the woods discretional application. T gum trees can be applied per plant per year 30 to 50 kg of organic fertilizer, nitrogen fertilizer 1 to 1.5 kg, 0.5 to 0.8 kg of phosphate fertilizer. Heavy cold damage zone and some K-deficient forest can increase potassium chloride 0.3 ~ 0.5 kg.
