摘　　要：为了解椰子优良新品种文椰2号、文椰3号、文椰4号和本地高种在云南省玉溪市元江哈尼族彝族傣族自治县(以下简称“元江县”)的适应性及生长状况,笔者到种植地进行现场调查,测量椰子生长指标,并与中国热带农业科学院椰子研究所(位于海南省文昌市)半岛基地(以下简称“椰子所半岛基地”)同株龄植株进行对比,结果显示,4个品种长势均较好。采集2个试验点的植株叶片进行干物质、氮、磷、钾含量的测定,根据现场植株长势和营养成分测定结果,提出了施肥建议。经调查认为,元江县海拔500 m以下地区的气候、环境完全适合椰子优良新品种的生长。In order to understand the adaptability and growth status of excellent new varieties, included Wenye No.2, Wenye No.3,Wenye No.4 and local high cultivars in Yuanjiang Hani, Yi and Dai Autonomous County, Yuxi City, Yunnan Province(hereinafter referred to as "Yuanjiang County"), the authors carried out field investigation in the planting area and measured some growth indexes, and then compared with the plants of the same age at the peninsula base of Coconut Research Institute,Chinese Academy of Tropical Agricultural Sciences(which in Hainan Wenchang)(hereinafter referred to as "Coconut Research Institute Peninsula Base"), it was found that the four varieties all grew well in Yuanjiang county. The leaves from Yuanjiang County and Hainan Wenchang Coconut Research Institute Peninsula Base were collected,and the content of N, P and K of the dry leaves were determined. According to the results of plant growth and nutrient composition determination,some suggestions on fertilization were put forward.The climate and environment of the area below 500 meters above sea level in Yuanjiang county are justified suitable for new varieties of coconut.
