【摘要】 橡胶树新品种热垦628于2004~2014年在云南省勐腊植胶区勐腊农场进行区域性种植试验,2011年正式割胶。统计结果表明:该品种生长较快,种植10 a平均茎围生长量68.89 cm,分别为传统种植对照品种GT1和PR107的115.70%和113.60%,种植后7 a达到开割标准的胶树为53.9%,比对照品种提前1 a投产,缩短橡胶树的非生产期,降低非生产期管理费用投入;开割第4年平均单株干胶产量达4.19 kg/株,分别为对照品种GT1和PR107的133.44%和187.05%,平均产量1 183.5 kg/hm2。该品种在勐腊植胶区表现出速生、高产、早熟等特性,是较好的胶木兼优品种,为对该品种的适应性和特性作出全面评价,应考虑在本地区进一步扩大试种并继续对其进行系统鉴定。更多还原

【Abstract】 The regional planting trails of ’Reken 628’ was started in Mengla farm of Yun Nan province from 2004 to 2014, and it was tapping in 2011. The results showed that ’Reken 628’ grows faster, stem diameter growth of ’Reken 628’ reached to 68.89 cm at 10 years old, which is 115.70 percent higher than’GT1’ and 113.60 percent higher than ’PR107’ as control clone. There is 53.9 percent of‘Reken 628’ which are 7 years old can reach the tapping standard, it is tapped one year earlier than control clones. This can shorten the time of non-productive period and reduce the cost. The dry rubber yield reaches 4.19 kg/tree and 1 183.5 kg/hm2 at the forth tapping year, which is 133.44 percent higher than ’GT1 ’ and 187.05 percent higher than ’PR107’. ’Reken 628’ shows the character of fast growth, high yield and early ripe in rubber planting area of Mengla. In order to study the characteristics and adaptability of ’Reken 628’ deeply,enlarging its planting trial and identifying its system are recommended.更多还原
