The regulator of this invention includes 150-250 mmol/L glucose and 5-10 mmol/L potassium chloride. The experiment of the invention discovers that there is a significant correlation between exogenous glucose and potassium chloride with glume flowers' differentiation number and existing number. The supplementation of exogenous glucose and potassium chloride 15-20 days before earring could significantly improve the content of non-structural carbohydrate (NSC) and the ratio of C/N in the vegetative organs of rice before earring, which is beneficial to glume flowers differentiation and can also reduce degradation and improve rice production.550 - Differentiation number X existing number 500 300 .................................... 450 - y =-0.0012+ 0.3836x+ 466.29 R2 = 04443 400 - y =-0.0011x 2+ 0.414&x+ 32S.83 R2 = 0329 3500 100 200 300 400 aucose concentration (nnur FIG. 1 1/2
