The production and fertilization status of 31 typical greenhouse vegetable bases，and the annual livestock and poultry manure output of Shunyi district，were investigated from August 2018 to June 2019.With the aid of an estimation model，the potential of organic fertilizer to replace chemical fertilizer in the vegetable industry in this area was analyzed. Results showed that the vegetables in the area were mainly sorted to fruit，leafy and melon type.The top 10 vegetables according to the planting area were as follows:tomato，watermelon，lettuce，Chinese cabbage，eggplant，pepper，celery，cabbage，lettuce and spinach.The total planting area of these 10 kinds of vegetables accounted for 84% of the total area of vegetable cultivated in the region.The solanaceous vegetables were mainly rotated with leafy vegetables，melons，lumps，and corn.The watermelons were mainly rotated with leafy and solanaceous vegetables.The leafy vegetables were mainly rotated with solanaceous，root vegetables，melons，onions and garlic.There were also rotations between leafy and fruit interiors.Solanum，watermelon and leafy vegetables all had flail cultivation problems.The average planting length of solanaceous，watermelon and leafy vegetables were about 120，100 and 60 d，respectively.The average inorganic and organic fertilizer inputs under greenhouse vegetable production were 850 kg/hm² and 28 t/hm²，respectively. According to the literature research results，when applied with half quantity of inorganic fertilizer，the quantity of organic fertilizer for melon and watermelon should be moderately increased，that for fruit vegetables should be avoided too high or too low，and that for leafy vegetables should be halved.Based on the vegetable planting and fertilization data，the calculated annual pure nitrogen，phosphorus and potassium inputs from chemical sources were 2107，1870 and 2344 t，respectively；that from organic sources were 979，522 and 1246 t，respectively；and that from the both two sources were 3086，2392 and 3590 t respectively.According to the livestock and poultry stocks data and the daily manure and urine output data in the whole region in 2018，the annual livestock and poultry manure output were calculated and followed the trend of:pig farm>cattle farm>sheep farm>chicken farm>duck farm，the pig farm achieved the first，and the cattle farm achieved the second.The total nitrogen，phosphorus and potassium nutrient replacement potential from pig farm and cattle farm were 63.4% and 27.3%，respectively.Taking into account the low annual excrement output and collection difficulty from sheep，chicken and duck sources，only the nutrient replacement potential from pig farm and cattle farm were calculated.Results indicated that the annual excrement from both pig and cattle farm in the district could be equivalent to 4477 tons of pure N，2371 tons of pure P2O5，and 5883 tons of pure K2O，the nitrogen，phosphorus and potassium replacement potential to local vegetable needs were reached to as high as 145%，99.1% and 164%，respectively.Converting animal manure and urine nutrient resource into organic fertilizer，and using it to substitute traditional chemical fertilizer in vegetable production has good planting-breeding standing condition in the studying district.
