本文对马来西亚与海南岛的崖县、儋县、定安等地的油棕单产作了比较,以马来西亚最高,其余依次递减,究其原因主要是海南各地有不同程度低温和台风为害所致。目前,在气温和台风难于人为控制的情况下,欲求海南油棕高产,只能择地而种。按油棕生态要求,可将海南划分为5个区:西南部干热区(崖县、乐东、东方等地),是海南种油棕最好的地方;东南沿海风热区(陵水、万宁等地),油棕达中年后易受风害,经济寿命短;西部旱寒区(儋县等地),油棕产量低于前两区,但高于其他油料作物;中部重寒区(通什、琼中、澄迈等地),种植油棕要冒风险;东北部风寒区(琼山、文昌等地),种植油棕较危险。
In this paper, we compare the yield of oil palm in Malaysia, Hainan Province, Yalong County, Ding’an and other places, with the highest in Malaysia and the others in decreasing order. The main reason is that there are different degrees of low temperature and typhoon damage all over Hainan. At present, the temperature and typhoon difficult to artificially control the situation, desire Hainan oil palm high yield, can only choose and species. According to the ecological requirements of oil palm, Hainan can be divided into 5 districts: dry hot area in the southwest (Cliff County, Ledong, the East and other places), Hainan is the best place for oil palm; wind southeast coastal hot zone (Lingshui , Wanning, etc.). Oil palm is vulnerable to wind damage after the middle-aged and has a short economic life expectancy. The output of oil palm is lower in the western drought-cold region (such as Pixian County) than in the first two regions but higher than those in other oilseeds. Heavy cold areas (Tong, Qiongzhong, Chengmai and other places), planting oil palm to take risks; northeast cold areas (Qiongshan, Wenchang and other places), planting oil palm more dangerous.
