双季槐引种适应性研究

Study on the Adaptation of Introduction of Sophora Japonica CV. Shuang Ji

采用不同密度、坡位、坡向3种处理对双季槐进行引种栽培试验,调查分析双季槐的成活率、保存率、生长量及结米量。结果表明,同一坡向、坡位,初植密度为825株/hm2的处理,成活率、保存率及结米量分别为98%,95%,1 800 kg/hm2,均高于其它处理,生长量也高于其它处理;同一密度、坡向,坡位为坡底(海拔550 m)的处理,成活率、保存率、结米量及生长量均高于其它处理;同一密度、坡位,不同坡向处理之间略有差异,但不明显。

Introduction and cultivation experiment of Sophora japonica cv. Shuang Ji was carried out, and 3 treatments of different density, slope position and slope direction were adopted. The survival rate, preservation rate, growth and yield were investigated and analyzed. Results showed that survival rate, preservation rate and yield of the treatment （the same slope position and slope direction, initial planting density was 825 plants/hm^2） were higher than that of control which were 98%,95%,1 800 kg/hm^2. And its growth was also higher than that of control. The survival rate, preservation rate and yield of the treatment （the same density and slope direction, slope position was bottom） were higher than that of control. There were difference between the treatments with different slope direction under the same density and slope position, but the difference was not significant.
