八一农场高产橡胶园产量报告

High Yielding of Rubber Plantations in Bayi State Farm

报道了海南省西部地区八一农场304队RRIM600无性系高产胶园的产量变化情况。胶园产量于第3割年(1997年)超过1500kg/hm2,第8割年(2002年)超过3000kg/hm2。初步分析,高产原因主要有割胶技术操作比较规范、重视有机肥的施用、推广四分之一阴阳线刺激新割制等。

The yield of high yielding rubber plantations （6.73 ha） of RRIM600 at Team 304 of Bayi State Farm in the west of Hainan was recorded since 1995 and the data analyzed. The rubber plantations produced over 1500 kg/ha at the third opening year （1997）, and over 3000 kg/ha at the 8^th tapping year （2002）. Judicial application of standardized tapping technique, organic manure and （S/4 ＋ S/4 t ）d/4 ＋ ET tapping system in these rubber plantations is likely responsible for their high yielding.
