2010~2016年在云南省德宏植胶区对‘热垦525’、‘热垦628’、‘热研8-79’、‘热研7-33-97’、‘湛试327-13’、‘IAN873’、‘云研77-4’7个橡胶树品种进行区域性栽培试验,调查比较其定植成活率、茎围生长量、抗寒性等性状。结果表明:不同橡胶品种,其定植成活率、茎围生长速度、抗寒性不同,‘湛试327-13’阳坡的成活率最高,为95.2%;阳坡生长由快慢顺序为‘热研7-33-97’>‘热垦525’>‘IAN873’>‘热垦628’>‘云研77-4’>‘湛试327-13’>‘热研8-79’;阳坡抗辐射型寒害能力强弱顺序为‘湛试327-13’>‘云研77-4’>‘热垦525’>‘热研7-33-97’>‘热研8-79’>‘IAN873’>‘热垦628’;从成活率、茎围生长量、抗寒性阳坡的数据来看,‘热研7-33-97’品种生长速度较快,‘湛试327-13‘品种成活率和抗寒性较好。
2010-2016 in Dehong, Yunnan gum plant ’hot reclamation 525’, ’Tengku 628’, ’hot research 8-79’, ’hot research 7-33-97’, ’Cham 327-13’ , ’IAN873’, ’Yunyan 77-4’7 rubber tree cultivars were cultivated in the region to investigate the comparison of its survival rate of planting, stem circumference growth, cold resistance and other traits. The results showed that: the survival rate of different rubber varieties, their colonization survival rate, stem growth rate and cold resistance were different.
