灌溉水要净化处理是保证滴灌系统正常运行的关键。针对温室滴灌系统中灌水器极易堵塞的现状,结合灌溉水中物理、化学杂质及直径的不同,分析堵塞原因。依据规范及相关研究成果提出了温室滴灌系统过滤器常用配置及优化配置的方法,以减少灌水器堵塞的概率,增加滴灌系统使用年限,减低成本。
Irrigation water to be purified to ensure the normal operation of drip irrigation system is the key. In view of the situation that the emitter of watermelon in the greenhouse drip irrigation system is easily clogged, the cause of the blockage is analyzed according to the difference of physical and chemical impurities and diameter in the irrigation water. According to the norms and related research results, the common configuration and optimal allocation of greenhouse drip irrigation system filters are proposed to reduce the probability of emitter blockage, increase the service life of drip irrigation system and reduce the cost.
