  • The field trial and pot experiment were condunted and the soil samples collected from allsites in the provinc were analysed to determine the content of availabl silicon and the effect ofSifertilizer in soil.The results showed that the available silicon content in cultivated land of Fu如nprovince was basically below the critical value (100 mg/kg).The yield of rice.sweetpotato.sugarcane.banana and other crops could be significantly increased when silicon calcium fertilizer wasapplied.Generally.the rice yield could be raisd by 5%-15% when 300-750 kg/hm=siliconcalcium fertilizer was applied.Moreover, silicon could facilitate the absorption of nitrogen and phosphorus by rice plants and accelerate N.P transfer to ears.Althrough the absorbed amount of K wasreduced, the rice grain yield increased.Application of silicon calcium fertilizer could reduce thepopulation of rice planthopper by 20%-60%and the incidence of banana bunchy top by 25%-50%.The silicon resource in Fujian province is avilable.so it can be further utilized.
