根据无性系早期测定结果,表明热研B号无性系为优良无性系。其平均树高、平均胸径和平均单株材积生长量均显著或极显著地大于实生树(对照);蓄积量极显著地大于其它参试无性系和对照;同时适应性较强,保存率高,风害较轻。建议在海南岛西部地区扩大试种或推广种植热研B号无性系。而在风害较重地区试种或推广种值大坡87号无性系,以及淘汰或限制推广白石岭06号无性系。
According to the results of early clones determination, it is indicated that the clone No.2 of Hot Research is an excellent clone. The average tree height, the average breast diameter and the average volume of plant growth were significantly or very significantly greater than the real tree (control); the accumulation was significantly greater than the other clones and controls; at the same time adaptability, high conservation Wind damage is lighter. Proposed to expand in the western part of Hainan Island to cultivate or promote the cultivation of hot research B clones. In the wind damage areas try to promote the species or value slope 87 clones, as well as to eliminate or limit the promotion of Pak Shui Ling 06 clones.
