土壤水分对作物根系生长及分布的调控作用

Roles of soil water in regulating root growth and distribution

冯广龙,刘昌明,王立。土壤水分对作物根系生长及分布的调控作用。生态农业研究,1996,4(3):5～9. 研究了作物根系生长、分布对不同土壤水分条件,特别是水分胁迫条件和不同灌溉方式的动态响应特征及其与冠部生长、籽粒产量和水分利用的关系,指出对作物根系实施调控的方法,为寻求节水高产途径提供了可靠依据。

Features of dynamic responses of root growth and distribution to soil water conditions, especially to water stress conditions and irrigation regimes as well as the relationship of root with shoot growth,grain yield and water use efficiency are reviewed with methods and ideas in root regulation for high yield and water-saving presented in this paper.
