常规灌溉方法效率低、水资源流失严重,随水渗漏的肥料给地表或地下水水质保持造成了巨大压力。而潮汐式灌溉作为底部灌溉的一种方式,不仅能显著提高灌溉效率,而且可有效阻止肥料渗漏,是一项在欧美花卉苗木产业发达国家应用普遍、技术成熟的高效、环保、节能灌溉技术。目前该技术在我国还处于引进、消化和吸收阶段,多在进行设备改造和系统调试,对潮汐式灌溉特点及其对植物生长影响的了解和研 Conventional irrigation methods are inefficient and cause serious loss of water resources. The fertilizer that leaks with water causes great pressure on the surface or groundwater quality. As a way of bottom irrigation, tidal irrigation not only can significantly improve irrigation efficiency, but also can effectively prevent leakage of fertilizer. It is a highly efficient, environmentally friendly and energy-saving irrigation technology that is widely used and mature in the developed countries in Europe and America . At present, the technology is still in the stage of introduction, digestion and absorption in our country, mostly in equipment modification and system debugging. It has a good understanding of the characteristics of tidal irrigation and its impact on plant growth
