Chitinase, antibiotics, plant growth promoting hormone were isolated from the decomposition chitin micro-bial using natural methods which have the capacity to control plant diseases and promote plant growth, named as CAPnew agricultural technology. Combined with emulgator and dispersing agents, a preparation of chitinase microbialsources as main component was made by fermentation method. In order to examine effects of chitin metabolites oligo-saccharides on cucumber, eggplant and cabbage, vegetable production, V_c, soluble sugar, protein and antioxidant ac-tivity were explored. The results demonstrated that cucumber and eggplant production increased by 3.6%~5.89%,and cabbage production rose to 122.86%, which was extremely significantly higher, when 50 m L/L CAP was applied.On the other hand, vegetables’ quality and fruits’ antioxidant activity were promoted to some extent.
