AbstractToverifytheapplicationeffectof silicon-containingwater-soluble fertilizeronrice，field plot experiments were conducted in Hexian County，Ma'anshan City（testsite1），and Xuanzhou District，Xuancheng City （test site2），both located in Anhui Province.3 treatments were designed： conventional fertilization + foliar application of silicon-containing water-soluble fertilizer 1OO mL/667 m2 （treatment 1）， conventional fertilization + foliar application of anequal volumeof clear water （treatment2），andconventional fertilizationalone（treatment3）.Theefectsofeach treatmentonrice agronomic traits，yield，and economicbenefits were systematicallycompared.Theresults showed that compared withtreatment3（conventionalfertilizationalone），treatment1increasedriceyieldby51kg/667m²withan increaserateof 8.4% and a net increased output value of 87.5 yuan/667 m² at the first experimental site.At the second experimental site，it increased yield by53kg/667 m2 withaincrease rate of 10.8% ，anet increased output value of 92.5yuan/667 m2.Inadition，compared with treatment 3，foliar application of silicon-containing water-soluble fertilizer in treatment1 also improved the stifnessof rice straw and enhanced lodging resistance.In conclusion，under theexperimental conditions，foliarapplicationof silicon-containing water-solublefertlizerexhibitedapotential yieldincreasing effect and favorable economic benefits on rice.
