Abstract:
Taking melon and pepper as materials,ecological effect of different microbial agents on rhizosphere soil microbes in facilities vegetables and their growth promotion,disease prevention were studied by dilution-plate method.The results showed that application of different microbial agents using watering roots processing could stimulate and significantly increase the populations of rhizosphere soil bacteria,fungi,actinomycetes three flora of facilities melon and pepper，with promoting plant growth，disease prevention and increasing yield effect.Especially treatment 1 was the best.Its relative control effect on facilities melon Fusarium wilt and pepper Phytophthora blight reached 88.9%～100.0%，and increasing rate was 10.2% and 16.06%，respectively；followed by treatment 2,its relative control effect on two kinds of soil born diseases reached 66.6%～77.8%，and increasing rate was 8.6% and 14.47%，respectively.Thus，application of microbial agents could improve obviously the rhizosphere soil micro-environment of facilities vegetables，decrease harmful pathogens，reduce the occurrence of soil born diseases and promote their healthy growth.
