摘要
从韩国引进龙牙檧木新品种进行根段繁殖、区域栽培和反季节栽培试验,结果表明,建国1号、高品芽、紫号、新区4个引进品种的耐寒性差,均不能在延边地区自然越冬;在温室进行反季节栽培,引进品种的嫩芽产值为90.2元.m-2,是国产种源的1.7倍,经济效益显著,是冬季温室水培的优良品种。
A series of trials of the new varieties, Jianguo 1, Gaopingya, Zihao, and Xinqiu, of Aralia data introduced from Republic of Korea were conducted on propagation by root segment, regional cultivation, and anti - season cultivation. Results show that all the four varieties have poor cold resistance and can not overwinter in the Yanbian area, Jilin, China. Anti - season cultivation was conducted for these introduced varieties of Aralia elata in the greenhouse, and the output value of budlets of the introduced varieties was 90.2 ynan·m^- 2 in average, which is 1.7 times that of the native provenance. These introduced varieties are superior varieties in hydroponic greenhouse in winter and have significant economic benefit.
