摘要
通过多年对高产小麦节水的土壤、品种、植株、根系、产量形成和水分利用等方面生理基础的研究,发现在播前足墒条件下,冬小麦拔节前水分胁迫可诱发6种超补偿效应而达到节水高产。以此理论为基础构建起高产小麦的生态节水和生理节水并举的综合调控技术体系并在生产上广泛应用。
The physiological basis of soil, genotypes, plants, roots, yield formation and water use for water saving and high yield in winter wheat was clarified by long term study. Results showed that water stress before elongation could induce several compensative effects to achieve water saving and high yield, when sufficient water is supplied before seeding. Based on the above theory, integrated regulating technical system for ecological and physiological water saving for high yielding winter wheat was established and widely applied in production.
