摘要
为改良滩涂盐碱地,并合理地对其开发利用,2000年和2001在江苏省盐城市滩涂进行了来自中国、俄罗斯和蒙古的不同沙棘品种的引种选育试验。试验结果表明:(1)引进的中国沙棘在盐度为0.1%～1.2%、土壤为重壤、中壤及砂壤区、地下水较高的滩涂成活率在80%以上,4年生中国沙棘树高在1.5～3.0m之间,冠幅在84～230cm×94～204cm之间,长势良好,并于2002年正常开花结实。表现出较好的抗逆、抗盐碱能力;(2)俄罗斯沙棘-“橙色”能较好地适应盐城滩涂生态环境,并于2002年正常开花结实,适宜在滩涂区大面积示范推广;(3)8个品种(辽阜1号、辽阜2号、杂交种、中国优、泽良、阿列衣、乌兰格木和红果)对滩涂生境有一定的适应能力,但其适应性和可推广性仍有待进一步研究。
To improve and reasonably exploit the tideland, some seabuckthorn varieties from China, Russia and mongolia were introduced into the Yancheng tideland in the Jiangsu Province during 2000~ 2001 The experimental results showed: (1) Survival rate of Hippophae rhamnoides ssp sinensis was over 80% on the tideland with soil salinity of 0 1% ~1 2%, the growth of four years seabuckthorn was good, with the height of 1 5~3 0m and crown of 84~230cm×94~204cm The Hippophae rhamnoides ssp sineniss normally flower and set fruit in 2002 This indicated the Hippophae rhamnoides ssp sinensiss have strong adaptability to harsh and salt marsh environment (2) The variety namely Orange from Russia had also good adaptability to eco-environment of the Yancheng tideland, and flower and set fruit normally in 2002 It could be planted in a large-scale in the tideland (3) Eight varieties, including Liaofu No 1, Liaofu No 2, Zaojiazhong, Zeliang, Alieyi, Uulangemu and Hongguo, had certain adaptability to the eco-environment in the tideland, but their adaptability need further study before large-scale planting
