Abstract:

The effects of silicon fertilizer on rice lodging resistance, yield performance and grain quality were investigated to prompt the sustainable development of Helonggongmi industry. With ‘Yuzhenxiang’ as material, 2 different silicon fertilizers (S1: Senfu and S2: Caidelong ETDA silicon fertilizer) were used and no silicon fertilizer treatment was taken as control. The effects on rice stem morphology and mechanical character, and grain production and quality were studied. The results showed that the application of silicon fertilizers had little influence on plant morphology characteristics (plant height, stem diameter, culm wall thickness, leaf length and leaf area). The grain production was enhanced by 2.82% and 4.83% under S1 and S2 treatment, the effective panicle number was increased by 11.57% and 13.74%, respectively, the head rice rate was increase by 7.48% and 13.07%, the thrust resistance was increased by 18.31% and 3.82%. Silicon fertilizer could enhance plant lodging resistance, increase grain production and improve quality to a certain extent, but the effects vary with silicon fertilizer types, and the S1 treatment is suitable for high yield cultivation of Helonggongmi.

Key words: Helonggongmi, silicon, yield, grain quality, lodging
