In order to verify the fertilizer effect of organic fertilizer of containing small monospora in vegetable production,two experiments are carried out in two parallel places in north China Plain. The test crop is green vegetables of thevariety with Shanghai Qing. We find the organic fertilizer tested is the small monospora organic fertilizer,and itsnutrient organic matter is greater than or equal to 45% and the effective nutrient is greater than or equal to 5%. Theconventional fertilization is 667 m2 with the application compound fertilizer of 50 kg and add the urea of 15 kg. Thetest uses a paired design method,with two treatments,four repetitions,and a cell area of 20 m2. The experimentalgroup is the routine fertilizer of adding 667 m2 with the organic fertilizer of small monospora in 20 kg. The controlgroup is the routine fertilization. The results show that the organic fertilizer increases the plant height,number ofleaves and weight of vegetables. The average yield of open land is per 667 m2 which is increased by 73.7 kg. Theincrease rate is 5.3%. The yield difference is reached a significant level. The average increase rate of the greenhouse is300 kg per 667 m2,and the increase rate is 10.1%. The difference in statistical analysis is reached a very significant level.
