Growth and Developmental Rhythm of Millet Root System and Its Dynamic Distribution in Soil

doi:10.3321/j.issn:1000-7091.1997.03.016

Abstract

Abstract: That the distribution of root weight and length in soil changed with time was studied by sampling root system at different stages for two millet varieties.The average extent of the root system of millet was about 130 cm,the root surface area at 0～20cm soil layer was more than 80% of the total one.The second ary roots developed at early stage usually growed to deepsoil,and the roots ocurred at late stage got into shallow soil which were the main root system during mid late period.Based on the determinations,dynamic simulation of millet root growth was established.

Key words: Millet, Root system, Simulation
