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。

This paper studied the three-dimensional distribution of Liman Peanut root in deep soil. In the experiment, Liman Peanut appeared up to the fifth root, the maximum number of roots was 13 227. At the seedling stage, the root system is an inverted cone-shaped structure composed of main roots and lateral roots of all levels. The main roots are the longest roots. From the seedling stage to the full-fruit stage, the upper part of the root system has a conical cone structure, For the approximate cylinder-shaped three-dimensional network structure, the lower part of the main root of the axis of the cylinder-like structure of the approximate structure, the longest side of the root is the longest root. In full fruit, the main root is not necessarily the deepest roots.
