摘要
微续灌是按照作物所要求的最适宜水分环境,连续对作物灌水的灌溉的一种灌水方式,灌水频率达到了与作物需水同步的无间隔灌水,这与作物连续需水特征相一致。采用微续灌使根区土壤含水量变化较小,而且总是保持作物理想生长的水平是可能做到的。微续灌不仅为作物生长提供良好的根际环境,具备良好的节水、增产潜力,并且系统的经济性优势明显,有望成为未来灌溉的重要发展方向。
Continued Micro-Irrigation is a kind of continuous irrigation mode which provides the most appropriate water environment for crops. Its irrigation frequency reaches the level, which is synchronous with the water requirement of crops without interval. Under continued micro-irrigation, the soil moisture in root zone changes inconspicuously, and may maintain the ideal state for the growth of crops. Continued micro-irrigation not only can provide good rhizosphere environment for the growth of crops. Also, it has good water-saving and yield-increasing potential and obvious economy advantage. Continued micro- irrigation may become an important development direction of irrigation in the future.
