简易滴灌是微喷滴灌方式中的一种,具有安装简单、移动方便、配套性好、故障少、省水省肥、成本低等特点。近年来,该项技术在南京市雨花台区设施栽培的蔬菜及草莓基地广泛应用,应用面积占总设施面积的40%左右,为种植户带来了较好的经济收益。1技术要点滴灌系统主要由水泵、混肥混药桶、输水管路、控制阀、软管滴灌管等组成。滴灌用水由潜水泵从机井或灌溉渠中抽取,通过主输送软管与棚内输送支管联接,用四通控制阀与具有一定间距滴孔的聚氯乙烯薄膜滴灌带对接,形成可控系统,通过控制阀门实现各区域灌溉,也可在肥料桶内将肥料、农药和水混合后一同用泵压入滴灌系统,与浇水同步实现施
Simple drip irrigation is a kind of micro-spray drip irrigation, with easy installation, easy to move, supporting good, less trouble, water and fertilizer, low cost and so on. In recent years, this technology has been widely used in the base of vegetables and strawberries cultivated in Yuhuatai District of Nanjing City. The area of application accounts for about 40% of the total facility area, which brings good economic benefits to the growers. 1 technical points Drip irrigation system mainly by the pump, mixed fertilizer barrel, water pipes, control valves, hose drip irrigation tubes and other components. Drip irrigation water from the submersible pump or irrigation canals drawn through the main transmission hose connected with the shed transport branch, with a four-way control valve with a certain distance drip of polyvinyl chloride film drip tape docking to form a controllable system by Control valves to achieve irrigation in all regions, but also in the fertilizer bucket will be fertilizers, pesticides and water mixed with a pump into the drip irrigation system, in synchronization with the water facilities
