摘　　要：为全面探究‘丰源1号’饲料桑新品种栽培的适宜土壤含盐量范围,本研究选取盆栽2年的饲料桑新品种‘丰源1号’,剪伐后立即进行不同浓度NaCl处理。结果表明NaCl处理后饲料桑的鲜重、叶片重量、枝条重量、叶片大小、树高等均显著下降,然而叶条比却有所增加。‘丰源1号’饲料桑的适宜种植范围应控制在土壤含盐量5‰以下。To comprehensively explore the suitable soil salinity range for cultivating the new variety of feed mulberry‘Fengyuan 1’,this study selected potted two-year-old plants and exposed them to different concentrations of NaCl immediately after pruning.The results showed that after NaCl treatment,the fresh weight,leaf weight,branch weight,leaf size,and tree height of the feed mulberry all significantly decreased.However,there was an increase in stem ratio.The appropriate planting range for‘Fengyuan’feed mulberry should be controlled at a salinity level of 5‰.
