摘要
以刺槐、榆树、臭椿、绒毛白蜡、杨树为试材,利用不同浓度盐溶液模拟盐胁迫条件,研究了盐胁迫对刺槐混栽苗生长特性的影响。结果表明:混栽的刺槐苗在低盐胁迫下生长较快,随着盐胁迫强度的增大,苗高生长急剧降低并有明显的波动;地径的生长速率变化与苗高不同,低盐胁迫下生长速率明显降低,在中等盐胁迫下,生长速率有所升高。
Effects on growth characteristics of pure and mixed seedlings of black locust were compared under salt stress in this paper. Results showed that at low salt stress, the growth of pure and mixed seedlings of black locust was rapid. With the increase of salt stress, the growth of seedlings decreased rapidly and had obvious fluctuation. Diameter growth rate performed differently from seedling growth. With low salt stress, the growth rate decreased significantly while with enhancement of the stress, the growth rate had increased.
