Practice and Consideration on the Construction of Solid-liquid Mixed Water and Fertilizer Management System for Facility Vegetables

Abstract: In order to meet the needs for water and fertilizer management equipment and technology in facility vegetables production of Beijing, a solid-liquid mixed water and fertilizer management system was introduced and constructed. The automation, data and precision of water and fertilizer management were achieved, the production and labor efficiency of the park had been improved. The economic benefit of facility vegetables increased 2 229 yuan per 667 m2 for one year in the real application. Based on the practice of system construction, some suggestions were provided from the aspects of water source design, antifreeze design, system maintenance service and how to improve the technical economy and applicability.
