In order to verify the application effect of polypeptide fish protein liquid fertilizer on rice,a field plot experiment was conducted to study the effects of different application rates of polypeptide fish protein liquid fertilizer on agronomic characters and yield of rice.The results showed that compared with the control,the plant height of rice under T2,T3 and T4 treatments increased;The four treatments of spraying polypeptide fish protein liquid fertilizer can increase the stem diameter,the highest tiller number,the number of grains per panicle and the 1000-grain weight of rice;T3 treatment(application rate 5 kg/667 m2)had the best effect in all aspects,and the yield was increased by 10.31％compared with the control.To sum up,the application of polypeptide fish protein liquid fertilizer in rice has significant yield-increasing effect,which is of great demonstration and popularization value.
