摘要:

针对国内农业种植水肥浪费严重、耗电多、人工成本高,相关技术装备整体水平落后的现状,文中提出了一种节水、节肥的潮汐式灌溉控制系统的设计。该系统利用植物的毛细原理,通过涨潮达到植物根部吸收水肥的目的,落潮时废液回收,经消毒等处理后可以再次循环利用,所有功能均由控制系统完成。经实验表明,该系统性能稳定,且采用潮汐灌溉方式,其灌溉用水量,耗电量和用工量,分别为人工喷灌的36.13%~44.21%,57.06%~59.64%和18.54%。潮汐式灌溉可以推动植物工厂化育苗的发展,具有良好的应用前景。

Abstract:

Based on the background of serious waste problems of irrigation and fertilization, power consumption, and high labor cost in agriculture, and underdeveloped techniques and equipments, a circuit design of the edd-and-flow irrigation control system with water and fertilizer saving is proposed. This system is a use for the realization of the principle of capillary irrigation techniques from plant roots, plant roots absorb water fertilizer by high tide and waste water can be recovered at low tide, after some treatments can be recycled again, such as disinfection, all functions are accomplished by the control system. Meanwhile ,compared to artificial irrigation ,this method can greatly reduce water, electricity and the consumption of labor by 36.13%~44.21%, 57.06%~59.64%, 18.54%.This irrigation can promote the development of plant seedling in factory, and has a broad application prospect.
