Abstract:: In order to study the effect of single microbial inoculum on continuous cropping pepper,the effects of germicide,Pseudomonas fluorescent Bacillus,Bacillus gigantobacilli,Bacillus subtilis,Pseudomonas fluorescent Bacillus+Bacillus gigantobacilli+Bacillus subtilis on the growth,yield and quality of pepper in arched shed were investigated by random region group method.The results showed that the plant height,stem diameter,crown diameter,fruit length,fruit size,fruit number of single plant and single fruit weight of continuous cropping pepper,under germicide and bacillus subtilis treatments were higher than those of the other 3 treatments and blank control.The total yield,yield and output value of bacillus subtilis treatment were higher than those of the other 4 treatments and the blank control,they were 202.3 kg,5 767.4 kg and 8 074.4 RMB,respectively.The yield increased by 9.1%,7.0%,4.5%,5.0%,10.7%,respectively.In the pepper harvest period,the highest vitamin C content in continuous cropping pepper was treated by Pseudomonas fluorescent Bacillus+Bacillus gigantobacilli+Bacillus subtilis,for 110.7 mg·g-1.Vitamin C content in the pepper treated by germicide was the second.The content of soluble sugar in the continuous cropping pepper was 19.58 mg·g-1,the soluble protein content of continuous cropping pepper treated by germicide was the highest,which was 1.81 mg·g-1.
