冬小麦节水省肥高产简化栽培理论与技术

Principle and Technology of Water-saving,Fertilizer-saving,High-yielding and Simple Cultivation in Winter Wheat

同步提高子粒产量和水肥利用效率对于我国华北地区小麦生产的可持续发展具有重要意义。我们经多年研究在严重缺水的河北省沧州地区建立了“冬小麦节水、省肥、高产、简化栽培‘四统一’技术体系”,使小麦高产和资源高效相结合。本文总结了这一栽培体系的主要原理,并介绍了技术的主要环节。

Increasing grain yield and improving water-fertilizer use efficiency simultaneously are very important for sustainable development of winter wheat production in Northern China. At Cangzhou Prefecture of Hebei Province, a shortest area of water resource in Northern China , through researches for many years, the cultivating system of water-saving, fertilizer-saving, high-yielding and simple management were developed in winter wheat, which combined high grain yield with high water-fertilizer use efficiency. In this paper, we reviewed main principles and key techniques of the cultivating system.
