Abstract：An investigation on vegetable fertilization in 2012 and 2013 was carried out in Anhui Province using sampling survey method，and the present status and existing problems of fertilization were analized and studied.The result indicated that there were 26 common vegetable species planted by surveyed househods in Anhui Province，among them 6 vegetables（pepper，tomato，cucumber，Chinese cabbage，cauliflower and eggplant） planted mostly by peasant households，were the main vegetable types in Anhui Province，which accounted for 52.1% and 67.4% of the total households number and vegetable acreage，respectively. Chemical fertilizers were applied in all farmlands，organic fertilizer only took 30.4%.The applications of nitrogen fertilizer all exceeded 300 kg·hm-2 in these 6 vegetables，and the average ration of N∶P2O5∶K2O was 1∶0.46∶0.49. There were big differences in organic fertilizer application among 6 vegetables.The average fertilizer applying frequency was 3.2 times in the whole vegetable growth period. The result also showed that cucumber yield was the highest，eggplant had the highest output value，and vegetable output value had significant positive correlation with fertilizer input. We should improve the current fertilizer applying technology，and speed up the application of soil testing and fertilizer recommendation technology in vegetable production.
