摘要
以加拿大引进的优良灌木树种银莓作为试验材料,进行了抗寒性测定及耐盐碱盆栽试验,并在吉林省西部及北方省份的区域试验,对银莓抗寒性及抗盐碱能力进行了综合评价。研究结果表明:银莓抗寒性强,在吉林省可自然越冬;银莓耐盐碱能力强,可在pH值为8.3～10.41、含盐量0.26%～0.64%的盐渍化地区生长。建议在吉林省西部乃至东北西部荒漠化土地的治理与改造中推广应用。
The cold resistance of silverberry （ Elaeagnus commutate ）, a superior shrubs species introduced from Canada, was determined, and a pot experiment was conducted under salt-alkali stress. The cold resistance and saline-alkali tolerance of E. commutate were synthetically evaluated in terms of the regional experimentations in western Jilin province and other provinces in North China. Results showed that E. commutate can live through the winter in Jilin province due to its strong cold resistance, It can also survive in saline soil with the pH value from 8.3 to 0.41 and salt concentration from 0, 26% to 0.64% because of its high saline-alkali tolerance. It is suggested that silverberry should be popularized and planted in the desertification control and restoration in western Northeast China.
