Applying Effect of Duntianbao Foliar Fertilizer on Growth and Grain Yield of Rice

[Objective] The research aimed to validate the effects of applying Duntianbao foliar fertilizer on the growth and grain yield of rice.[Method]Sterile water transplanting was conducted. Every main growth stages of the rice were investigated and recorded. Every indicators of yield trait were recorded. [Result] Duntianbao foliar-fertilizer could increase the effective number,total number of grains per spike,kernel number,and improve 5. 01%-12. 6%. [Conclusion] Further study of action mechanism of Duntianbao foliar-fertilizer on the yield increase of rice should be carried out.
