油棕在云南保山干热河谷区引种适应性初步评价

Preliminary evaluation on adaptability of the introduced oil palm in dry-hot valley of Baoshan,Yunnan province

为评价油棕在干热河谷地区的生长表现,于2011年从海南引进‘热油2号’‘热油4号’‘热油6号’和‘热油8号’4个油棕品种在云南保山干热河谷区试种,并按照农业农村部油棕品种区域适应性试种观测相关技术规范开展抚管和观测。经过多年引种观察,4个油棕品种在云南保山干热河谷区均能正常生长发育,表现出较强的适应性,其中‘热油2号’株高、茎高、年新增叶片数、冠幅生长量最大,‘热油4号’果穗性状、果实性状表现最优,可作为生产上小规模试验性试种材料推广种植。

To evaluate the growth performance of oil palm in the dry-hot valley,four varieties of oil palm Reyou 2,Reyou 4,Reyou 6 and Reyou 8 had been introduced from Hainan in 2011 to carry out trial planting in the dry-hot valley of Baoshan,Yunnan province.The management and observation were conducted according to the technical specifications for observation of regional adaptability trial planting of oil palm varieties issued by Ministry of Agriculture and Rural Affairs.After years of seed introduction and observation,all four oil palm varieties could grow and develop normally in the dry-hot valley area of Baoshan,Yunnan province,and had shown strong adaptability.Among them,Reyou 2 had the largest growth in plant height,stem height,annual number of new blades and crown bredth,Reyou 4 had the best performance in ear and fruit traits,so Reyou 2 and Reyou 4 could be promoted as a small-scale trial planting material for production.
