摘　　要：The root morphology of erect type peanut in deep soil was studied in this paper. In the experiment, erect type peanut showed as most as five-order lateral roots with 13 227 pieces of lateral roots. At the seedling stage, the root system of erect type peanut was handstand cone-typed with lateral roots at various orders distributed around the taproot, and among the roots, the taproot was longest. During the late seedling stage to mature stage, the upper part of the root system of erect type peanut was blunt cone-typed, the middle part was three-dimensional network typed, while the lower part was cyUnder-like. The longest first-order lateral root was the longest root. At the mature stage, the taproot was not always the deepest root.该文研究了立蔓型花生在深厚土体中根系生长立体分布状态。试验中,立蔓型花生最多出现五级根,根条数最多为13 227条。在苗期,根系是以主根为轴心、各级侧根组成的倒立的圆锥体型结构,主根是最长的根:从苗期未期一直到饱果期,根系上部为钝圆锥体结构,中间为近似圆柱体型的立体网状结构,下部为以主根为轴心的近似圆柱体型框架结构,最长一级侧根是最长的根。在饱果期,主根不一定是入土最深的根。
