滴灌技术的应用,在我国蔬菜生产上大多还处于小面积的试验阶段。为了探索大面积蔬菜生产应用滴灌技术的可能性,自1986年以来,我们在卢沟桥乡对塑料大棚不同种类的蔬菜,进行了总面积近100亩的多点试验和生产应用,取得了可喜成效,受到菜农的普遍欢迎。一、滴灌系统的组成滴灌系统主要有供水装置、输水管和滴水软带三部分组成。供水装置:水泵从井中抽出水后,流入容量为2～8吨的压力罐,加压至2～5kg/cm~2。浇灌面积大,则压力罐的容量及压力应适当加大。压力罐安有自动补水装置,以保证均衡供水不断。
Drip irrigation technology, most of our vegetable production is still in a small area of the pilot phase. In order to explore the possibility of large-area vegetable production and application of drip irrigation technology, since 1986, we conducted a series of multi-point experiments and production applications on a total of nearly 100 mu of plastic greenhouses in different types of vegetables in Lugouqiao Township and achieved gratifying results. By vegetable farmers generally welcomed. First, the composition of drip irrigation system drip irrigation system mainly consists of three parts, water pipes and drip soft. Water supply device: After pumping water from the well, the pump will flow into a pressure tank with a capacity of 2 to 8 tons and pressurize to 2 to 5 kg / cm ~ 2. Watering area, the pressure tank capacity and pressure should be appropriately increased. Pressure tank equipped with automatic replenishment device to ensure a balanced water supply.
