Influence of Application of Different Fertilizers on Economic Benefit of Vegetables Cultivation

[Objective] The study was to generalize the use of organic fertilizer further and serve the construction of ecology agriculture more effectively.[Method] The bio-organic fertilizer and chemical fertilizer were applied in the cultivation of Chinese cabbage and cowpea.After harvested,their economic benefits were compared.[Result] During the planting process of Chinese cabbage,compared with chemical fertilizer,the base fertilize,top dressing,pesticide cost and total cost of application of organic fertilizer was saved by 8.30%,9.80%,50.60% and 15.20% resp.and the ratio of output to input of the application of bio-organic fertilizer and chemical fertilizer was 4.35,3.62 resp..During the planting process of cowpea,compared with chemical fertilizer,the base fertilize,top dressing,pesticide cost and total cost of application of chemical fertilizer was saved 12.30%,12.40%,35.97% and 21.78% resp.and the ratio of output to input of the application of bio-organic fertilizer and chemical fertilizer was 3.86,2.99 resp.[Conclusion] The application of bio-organic fertilizer decreased the application of pesticide,increased the vegetables yield and made the economic returns obviously better than that of chemical fertilizer.
