Abstract：In order to optimize the fertilization measures for barley cultivation in Bazhong area,the effect of different fertilizer application rates on the yield of Ganpi No.8 was investigated.The experiment was set up with 225kg/hm2 compound fertilizer as the control(CK),and was divided into 2 types of treatments[basal+topdressing(A)and versus basal alone(B)].Each type of treatment was further divided into 4 levels.The results showed that yield was positively correlated with plant height,spike length,spike formation rate,seed setting rate,number of grains per spike,number of spikes,number of stems per plant,and significantly positively correlated with thousand-grain weight.Under B1,B2,B3 and B4 treatments,barley yield increased with the increase of basal fertilizer application rates,and the barley yield under the B4 treatment was the highest,with 4 882.4 kg/hm2,which was 166.0％more than that of the CK.When total fertilization amount was 450 kg/hm2 and 600 kg/hm2,the yield of A1 was higher than that of B1,A2 was higher than B2,and the opposite was true when it was more than 600 kg/hm2.Sufficient amount of basal fertilizer was helpful to increase the yield of barley.
