Cucumber, cabbage( Brassica oleracea L.), and cowpea as acceptor materials, the effects of four concentrations of (0.01 g/ml, 0.02g/ml, 0.03 g/ml and 0.04g/ml) root, stem and leaf aqueous extracts of pepper on the allelopathy of recipient vegetable and the enzyme activity in rhizosphere soil were studied. The results showed that the allelopathic effect of different tissue extracts of pepper was leaf > root > stem, and the greater the concentration of treatment solution, the stronger the inhibitory effect on the recipient vegetables. According to the value of the comprehensive membership function, the order of the allelopathic effect of different tissue extracts of capsicum on the recipient vegetables is cucumber > cabbage > cowpea. The concentration of the pepper extract, the extraction site, and the difference of the acceptor materials can affect the soil enzyme activity. The urease activity increases with the increase of the concentration, and the catalase and sucrase activities increase first and then decrease.
