摘　　要：通过分析辣木不同树龄的根系形态特征,揭示其根系生长与树龄之间的内在联系,为辣木的优质栽培和大田管理提供科学依据。试验以1、3、5年树龄的辣木根为材料,测量根数、根深、根幅、根系鲜质量、茎粗及平均根长等参数,分析不同树龄辣木根系生长变化情况。结果表明:随树龄增加,根数、平均根长、根系鲜质量、茎粗、根深、根幅均呈显著增加趋势,各根系特征之间存在显著正相关关系;垂直与水平方向的根数和根粗也随树龄的增加而增加,且垂直方向优于水平方向。This experiment analyzes the morphological characteristics of the root system of Moringa trees at different ages,revealing the inherent relationship between root growth and tree age,and providing scientific basis for high-quality cultivation and field management of Moringa trees.Using 1 year,3 years,and 5 years old Moringa roots as materials,parameters such as root number,root depth,root width,total root weight,stem thickness,and average root length were measured to analyze the growth changes of Moringa root systems at different ages.The results showed that with the increase of tree age,the number of roots,average root length,total root weight,stem thickness,root depth,and root width all showed a significant increasing trend,and there was a significant positive correlation between various root characteristics;The number and thickness of roots in the vertical and horizontal directions also increase with the age of the tree,and the vertical direction is better than the horizontal direction.
