RRIM600在海南垦区20多年的栽培过程中,基本上适应生产上推广的种植形式。在正常的抚管条件下,7~8年可投产,且产量较高,但开割后易死皮,不耐刺激,不宜深割;经合理修剪可明显提高其抗风力;幼树可提早针刺采胶。为了进一步发挥RRIM600的产胶潜力,在栽培管理上应注意合理密植,亩植40株左右;开割标准可定为45厘米;初割时,强度要降低,头两割年用S/2·d/13割制;要严格控制死皮;使用刺激剂和改变割制一定要慎之又慎;绝不能趋深割胶;把修剪做为一项必不可少的技术措施。
In the more than 20 years of cultivation in Hainan reclamation area, RRIM600 basically accords with the planting forms promoted in production. Under the normal conditions of the tube, 7 to 8 years can be put into operation, and the yield is high, but after cutting cut easily, impatient stimulation, should not be cut; reasonable pruning can significantly improve its wind resistance; young trees can be earlier Acupuncture mining plastic. In order to further develop the yield potential of RRIM600, attention should be paid to the rational cultivation of close planting, planting about 40 acres; cutting standard can be set at 45 cm; initial cut, the intensity to be reduced, the first two cut years with S / 2 · d / 13 cut; to strictly control the dead skin; the use of stimulants and cutting change must be cautious; must not deepen the tapping; the pruning as an essential technical measures.
