| 摘 要： | 中国目前没有专门的油棕授粉昆虫,油棕园主要靠风媒和人工授粉。为研究人工授粉对油棕产量的影响,分别在12个油棕品种上进行了试验,并与风媒授粉作了比较。结果表明,人工授粉:(1)显著提高了座果率,平均由62.25%提高至89.18%;(2)显著改善了产量性状指标,其中:平均果串重由6.18kg增加至12.40kg,增幅100.64%;果实占果穗平均比重由52.53%增加至66.02%,增幅13.49%;果穗含油率平均由21.71%增加至28.76%,增幅7.05%;核仁占鲜果串比重平均由7.70%增加至8.62%,增幅0.92%;(3)显著提高了鲜果产量,平均增加了61.1%,毛棕油产量提高了113.4%,经济收益增幅达103.23%。

| Abstract: | Oil palm trees are mainly pollinated by wind or artificially in China since there are no special pollinating weevils such as Elaeidobius kamerunicus in oil palm plantations.Twelve cultivars of oil palm were pollinated artificially in an experiment,and their yield was compared with that of the oil palm pollinated by wind.The results showed that artificial pollination improved significantly fruitsetting rate,yield trait indexes and hence fresh fruit weight as compared to wind pollination.The cultivars treated... |
