日光温室蔬菜生产必须灌水才能增产增收,但是灌水能增加棚内的湿度,易引发多种病害,施药又污染了蔬菜,这是棚菜生产的一大难题。为此,我们设计了地下自动暗渗灌水追肥的新设施,经多年实验取得良好效果。 一、地下自动暗渗灌水、追肥设备的结构及实施方法 地下自动暗渗灌水、追肥设备由贮水、送水、供水三部分组成。贮水池设温室内中部后墙内,用红砖、水泥砌成,东西长2米,南北宽1米,高1.2米。贮水
Solar greenhouse vegetable production must be irrigated to increase production and income, but irrigation can increase shed humidity, easily lead to a variety of diseases, pesticide application and pollution of vegetables, which is greenhouse production a major problem. To this end, we have designed a new underground automatic infiltration of fertilizer new facilities, after years of experiments achieved good results. First, underground automatic infiltration irrigation, top dressing equipment structure and implementation methods Underground automatic infiltration irrigation, top dressing equipment from storage of water, water, water supply is composed of three parts. The cistern is set in the back wall in the central part of the greenhouse. It is made of red brick and cement, with a length of 2 meters and a width of 1 meter and a height of 1.2 meters. Water storage
