WU Shi ping, YAN Si huang, LU De qing(Institute of Plant Protection, Guizhou Academy of Agricultural Sciences, Guiyang 550006, China)  
Chilli yield was obviously raised by applying Trichoderma strain under the condition of four groups of N,P,K fertilizer to be used, the yield increase ranged from 7.7% to 20.8%; It was more benefit to Trichoderma colonization in rhizosphere, stimulation of pant growth and yield increase when less fertilizer was applicated, the yield increase caused by Trichoderma reached up to significant standard level in both treatments of N168.75kg/hm 2, P56kg/hm 2, K50kg/hm 2 and N58.8kg/hm 2, P56kg/hm 2, K50kg/hm 2. Better rhizosphere colonization of Trichoderma and chilli yield increasing caused by the antagonist appeared in ridging cultivation than in plain growing. The cash income increased by application of Trichoderma was 1283~ 3550yuan/hm 2 (RMB).
