云南的辣木引种试验初报

在云南的开远、东川、永仁、思茅、瑞丽5地进行了8个种源,2个品种的辣木引种试验,所引种的辣木其幼树期表现出生长迅速,能正常开花结实的状况;且所引种的10个种源(品种)间生长差异并不显著。辣木定植后,呈现持续生长的状态,无明显缓苗期;年生长态势在年内大部时间生长迅速,到11月初随着温度的下降而生长减缓,粗生长在后期增长明显加快。表明辣木生长受温度影响较为明显,对温度的变化较敏感。引种的辣木植株1年生枝耐修剪,显示其为易于更新的树种。另外,引种的辣木叶中蛋白含量与原产地基本相同,但钙、钾、镁等微量元素的含量低于原产地,而维生素含量则高于原产地。

A Preliminary Report on Introduction Experiment of Moringa oleifera in Yunnan

Introduction and cultivation experiment of Moringa oleifera including 8 provenances and 2 varieties were conducted in Kaiyuan,Dongchuan,Yongren,Simao and Ruili of Yunnan province.Moringa oleifera showed good performance in these areas of Yunnan province with fast growth and normal flowering and fruiting,and the difference among provenances and varieties were not significant,and there was no obvious reviving stage.In most time within a year,Moringa oleifera showed fast growth,from November as the temperature decrease,the growth speed decrease.The growth was significantly affected by temperature,and was quite sensitive to the change of temperature.One year old branch had good tolerance to pruning,which implied that Moringa oleifera was a species with good regeneration ability.The protein content in leaves of Moringa oleifera was basically the same with the plants in origin place.The contents of Ca,K and Mg were lower than that of origin place.The content of vitamin was higher than that of origin place.
