摘要
从葛根主茎上段、中段、下段3个不同部位剪取单节进行育苗,以出苗率、平均株高、根长和根粗为统计指标,分析不同处理葛根苗木的生长情况.结果表明,用主茎中段葛藤育苗,出苗率最高(达到80%以上),平均株高、主根根长和粗度均明显高于其他处理,并且带有根瘤菌,可广泛推广到生产实际中.
The upper,middle,and lower segments of Kuzdvine root were sheaved for seedling culture.Emergence rate,average plant height,and root length and thickness being statistic index,the growth of seedlings were analyzed.The results show that the middle segments have the highest emergence rate(above 80%),and average height,length and thickness the seedlings from the middle segments are higher than those from other segments.Moreover,seedlings from the middle segments have rhizobium.In conclusion,seedling culture from middle segments of Kudzuvine root can be promoted.
