Abstract: Spraying zymolitic liquid of Trichderma in cabbage and cucumber in Shajiang black soil of Huaibei area, the results showed that applied Trichderma can promote vegetable growth, the grow properties of cabbage and cucumber have been obviously improved, and the yield obviously increased too. Comparing two kinds of farm crop, the increasing potential of cucumber is larger. Cucumber and cabbage’s output value have been increased in different degree when applied Trichderma. The result of increasing yield and income of cucumber should more obvious than cabbage. It is best that applied Trichderma of high deal in cabbage, but cucumber applied low deal is best.
