富源县薄壳山核桃引种初报

对富源县域内2个薄壳山核桃引种点栽培的薄壳山核桃生长量、开花结实特性、果仁粗脂肪、蛋白质等营养成分及薄壳山核桃油脂肪酸组成等进行调查研究。结果表明,薄壳山核桃在富源县生长发育正常,对气候环境有良好的适应性,嫁接苗定植6 a时部分植株开始初果,10 a时产量最高,达3.3 kg/株;富源县薄壳山核桃花期为4月上旬至5月中旬,开花盛期品种间存在差异,同一品种存在雌雄花异熟性,在时间上不完全重合,应根据品种开花特点实行多品种配置栽培;富源县薄壳山核桃种仁富含油脂、蛋白质、可溶性糖等营养物质,初步分析认为,富源县气候环境适宜种植发展薄壳山核桃,以海拔低于1800 m区域最适宜。

Preliminary Report on Introduction of Carya illinoensis in Fuyuan County

The growth,flowering and fruiting characteristics,the composition of fatty acids and the contents of different nutritional components,such as crude fat and protein of mature nuts of Carya illinoensis were investigated in two introduction sites of Fuyuan County.The results showed that the growth of Carya illinoensis was normal in Fuyuan County,which had good adaptability to the environment.The grafted seedlings initially bore nuts during the sixth year after planting,and the nut yielded up to 3.3 kg per tree during the tenth year after planting.The flowering time of Carya illinoensis in Fuyuan was from early April to mid-May,and the full-blossom periods were different between different cultivars.Carya illinoensis trees showed dichogamy,which should carry out multiple cultivars cultivation according to the flowering characteristics of varieties.The kernels of Carya illinoensis were rich in fatty acids,proteins and solublesugars.The preliminary analysis showed that the climate environment of Fuyuan County was suitable for the cultivation of Carya illinoensis,and the area with the altitude below 1800 m was the most suitable.
