设施大棚是一个相对封闭的生产环境,内部湿度高,易发生病虫害。为有效控制设施内部湿度,减少病虫害发生,常采用滴灌或微喷灌方式来满足作物对水分需求,其中前者常配置水肥一体化设备。微灌施肥设备主要包括供水泵、控制阀、过滤器或过滤网、文丘里施肥器、施肥阀、肥液桶、PE薄壁输水管、滴灌带(微喷带)、连接管件等。正确使用和维护保养微灌施肥设备,将有助于充分发挥其四节(节水、节肥、节能、节药)、三省(省工、省力、省钱)、两增(增产、增收)作用。1.正确使用(1)操作人员要求(1)操作人员应熟悉和掌握整套设备的安全操
Facilities Greenhouses is a relatively closed production environment, high internal humidity, prone to pests and diseases. In order to effectively control the humidity inside the facility and reduce the occurrence of pests and diseases, drip irrigation or micro-sprinkling irrigation is often used to meet the water requirement of crops. The former is often equipped with integrated water and fertilizer facilities. Micro-irrigation fertilizers mainly include water supply pumps, control valves, filters or filters, Venturi fertilizers, fertilizer valves, fertilizer barrels, PE thin-walled water pipes, drip irrigation tapes Proper use and maintenance of micro-irrigation fertilization equipment will help give full play to its four sections (water saving, fertilizer, energy saving, section medicine), three provinces (labor, labor, money) effect. 1. Proper use (1) operator requirements (1) the operator should be familiar with and master the safety equipment
