Through plot experimental comparison design,different foliar fertilization methods of cold rice were studied in order to get the most appropriate fertilization methods in the late of cold rice.The experimental results showed that with the increasing of foliar spraying,the incidence were gradually decreased,the theoretical yield gradually increased,the processing quality of rice were gradual deterioration,but there were no significant effect of appearance quality among the treatments of the cold rice.The best economic benefit was gotten from 2 foliar sprays,in which yield was increased by 6.70%,economic benefits was 27604.16 yuan/hm²,net benefit was 1734.19 yuan/hm².
