摘要
以PR107为对照,对试种在海南中部山区乌石分公司橡胶优良品种热研7-33-97的生产系比的生长、产量及抗性等性状进行鉴定研究,结果表明:热研7-33-97生长较快,开割前、后茎围年均增长6.1和2.8cm;产量较高,开割第1和第4年干含平均为31%,开割当年年均株产和亩产分别为2.5kg/株和694.5kg/hm2,抗寒性、死皮率及经济效益表现等均优于对照PR107,是对海南中部山区有良好适应性的优良品种,可在该区域逐步扩大种植面积。
Rubber clone Reyan 7-33-97 （Hevea brasiliensis） was planted by the Hainan Rubber Group Wushi Branch in a commercial clone trial in the central mountain area in Hainan Province to determine its growth, yield and resistance as well as other characteristics with the PR107 as the control. The clone Reyan 7-33-97 grew faster with the annual girth growth rate of 6.1 cm before and 2.8 cm after the opening for tapping. It yielded higher; the mean dry rubber content was 31% at the first and fourth years after the opening; the annual yield at the first year of tapping was 2.5 kg/tree or 46.3 kg/mu （694.5 kg/ha）. This clone performed much better than the control PR107 due to its higher coldhardiness, low tapping panel dryness incidence and higher economic benefits. It is hence recommended for gradual expansion in this region.
