Effect of Applying Different Liquid Silicon Fertilizers on the Growth Character of Rice Along the Yangtze River
Taking rice variety Huiliangyouyuehesimiao as experimental materials,field experiments were conducted to explore the effects of three types of liquid silicon fertilizers on rice growth and lodging resistance traits,in order to provide a new technological approach for green and efficient rice production in the rice growing areas of the Yangtze River Basin.The results indicated that spraying liquid silicon fertilizer could significantly increase the sword leaf area of rice during the booting stage,with an increase range of 13.1% to 24.6% .Spraying liquid silicon fertilizer A and C could significantly increase the sword leaf area of rice during the full heading stage,with an increase range of 9.4% and 19.6%,respectively;spraying liquid silicon fertilizer B could significantly increase the tillering number of rice during the peak tillering stage,but it was not significant for the increase in tillering number of rice during the full heading stage.Spraying liquid silicon fertilizer C could in-crease the tillering number by 26.9% during the full heading stage and achieve a significant difference;spraying liquid silicon fertilizer C dur-ing the heading and harvesting stages would significantly increase the fresh weight of single hole roots in rice,and the increase was higher than that of A and B;the treatment of spraying liquid silicon fertilizer C during the heading stage had the highest SPAD value,which was 10.2% higher than CK,and the difference was significant;spraying liquid silicon fertilizers A and C could significantly reduce the lodging index of rice during the poplar flowering period and improve its lodging resistance;spraying liquid silicon fertilizers B and C could significantly increase the effective panicle number of rice,with an increase of 5.8% and 9.4% respectively;there was no significant difference in the number of grains per spike among the treatments;the treatment of spraying liquid silicon fertilizer B had the lowest thousand grain weight;spraying liquid silicon fertilizer C could significantly increase rice yield,with a yield increase of 14.3% .Taking into account various growth indicators and yield fac-tors of rice at different growth stages,this study showed that spraying liquid silicon fertilizer C during the jointing,heading,and filling stages of rice in the rice growing areas along the Yangtze River had the strongest effect on promoting rice growth,increasing rice yield,and resisting lodg-ing,making it the best foliar fertilizer variety.
