Model of root system for winter wheat and water uptake

摘要

Using experimental data on winter wheat from Bushland, Texas and Zhengzhou, Henan, analysis is performed of the distribution of its root system in 0～50 (50～100) cm soil depth, with the density of root length and its weight making up 57.7% (23.4%) and 66.7% (18.7%), respectively, thereby constructing the model of the roots growth and also by the distribution of the root system and its water absorption, study is undertaken of the appropriate depth of background field moisture for growing winter wheat.
