橡胶优良品种海垦2在云南的适应性

Adaptability of Rubber Clone Haiken 2 in Yunnan

橡胶树优良品种海垦 2在云南省热带作物科学研究所、勐捧农场、孟定农场的适应性试验研究表明 ,1～ 11割年平均单株年产干胶 5.2 7kg ,是对照RRIM6 0 0的 12 2 .8% ;单位面积产量为 2 0 96kg/hm2 ,是对照RRIM6 0 0的138.5%。海垦 2干胶含量高 ,产胶潜力大 。

In order to study the adaptability of the high yield Hevea clone Haiken 2 in Yunnan rubber plantation areas, the clone has been cultivated in the Tropical Crops Research Institute of Yunnan、 the Experimental Station of Mengpeng State Farm and Mengding State Farm. Eleven year's tapping show the average yield of per tree is 5.27kg/tree/year, which is 122.8% of the control RRIM600. The average yield in a unit area is 2096kg/ha/year, which is 138.5% of the RRIM600. The dry rubber content of the latex of Haiken 2 is significantly higher than the control that means higher production potential of the clone. The Clone is recommended to cultivate in large scale in the first class rubber plantation area.
