The field experiments were conducted with Yanfeng47,a high-quality ricevariety,as the test material. Theeffects of silicon-calcium fertilizer and liquid silicon fertilizer on ricegrowth,yield and quality were studied by comparingplots,facility fertilizer(7)and transplanting basic seedlings with 14 treatments. The results showed that both siliconfertilizers could increase tiller number,panicle yield,yield,lodging resistance and disease resistance,improve ricequality,reduce chalkiness and chalky grainrate,and improve brown ricerate,milled rice rate and finishing rate. Among the 64.5×104seedlings per hectare of the basicseedlings,the highest yield of C5-1 was 10 893.0 kg/hm2.
