研究了不同水不溶物含量的水溶性肥料对滴灌施肥系统过滤器堵塞的影响。结果表明，以膨润土为填充料的供试肥料（膨润土肥料）和凹凸棒土为填充料的供试肥料（凹凸棒土肥料），在水不溶物质量分数为2％以上时43min内均可使过滤器两端的压力差达到0．05MPa，并最终使过滤器完全堵塞。

The effects of different water-insoluble substance in water-soluble fertilizers on the filter clogging in fertigation are studied. The results show that, both bentoniet fertilizer and attapulgite fertilizer, when the mass fraction of water-insoluble substance in water-soluble fertilizers is above 2%, the pressure difference between two sides of filter is reached 0.05 MPa in the 43 min, finally the filter is completely clogged.
