中国滴灌施肥技术优缺点分析与发展对策

为了解决肥水制约中国农业发展的问题，文章综述了国内外近20年滴灌施肥技术研究进展，发现滴灌施肥技术具有节水、节肥、省工、增产、地形适应能力强等优点，但滴灌施肥技术还存在滴头堵塞、盐分积累以及首次投入成本高等不足。要促进此项技术的广泛使用，既要依靠政策驱动和技术创新促进滴灌施肥技术发展，又要强化培训和示范推广提速该项技术的应用，今后还需研究水肥药平衡和自动化控制技术，以促进中国精准农业的发展。

The Analysis of Advantages and Disadvantages of Fertigation Technology and Development Strategies in China

In order to solve the problem fertilizer and water restricting China＇ s agricultural development, the article reviewed fertigation technology research in the past 20 years at home and abroad. The research found that： fertigation technology had an advantage of water-saving, fertilizer section and provincial workers. Furthermore, fertigation technology also improved crop production and use terrain adaptability, etc. However, fertigation technology existed some disadvantages, such as emitter clogging, salt accumulation and higher input costs for the first time. To promote the widespread use of this technology, it was necessary to rely on policy-driven and technological innovation to promote the development of fertigation technology, but also to strengthen the training and demonstration to promote speed of the technology application. In the future, it needed to study water, fertilizer balanced medicine, and to study automation control technology for promoting Chinese development of precision agriculture.
