摘　　要：在凉山州安宁河谷区首次进行土壤消毒、追施微生物菌肥复合联控设施蕃茄土传病害。结果表明,施用二氧化氯灭杀真菌7种,菌种灭杀率63.64%;灭杀细菌7种,菌种灭杀率77.78%,存活的4个真菌菌种、2个细菌菌种数量大幅降低,广谱杀菌效果显著;追施坤奇尔+特锐菌复混微生物菌肥,新生真菌4种、细菌8种,土传病原立枯丝核菌、镰刀菌属、齐整小核菌和尖镰孢菌4个菌种和1个细菌菌种数量分别从肥前的3.58%、5.22%、3.16%、7.25%、3.26%降至肥后的2.71%、1.32%、1.27%、3.56%、0.83%,拮抗效果明显;与对照相比,药肥复合栽培,蕃茄纵径伸长量变化差异显著,横径在花后8d,花后18d,花后29d的伸长量变化差异显著,花后41d差异不显著,蕃茄增产18.2%;与对照相比,蕃茄全生育期茎基腐病、青枯病、枯萎病、白绢病发病率和病情指数分别下降73.69%、64.99%、40.08%、43.97%和78.22%、74.40%、30.97%、34.79%,药肥联控土传病原效果显著,对茎基腐病病原拮抗最好,枯萎病病原拮抗最差。Soil disinfection method was applied for the first time in Liangshan prefecture＇s Anning river valley area,topdressing compound inorganic feilizer culture joint prevention and control facilities tomato soil borne diseases. Resultsshowed that the application of chlorine dioxide killed fungi seven, bacteria killing rate of 63.64%, killing seven kinds ofbacteria, bacteria killing rate of 77.78%, surviving four sharp decline in the number of fungi strains, 2 bacteria strains ofbroad-spectrum sterilization effect is obvious. Topdressing kunqier and sharp new fungus bacteria compound mixedfertilizer, 4, 8 kinds of bacteria, soil borne pathogen made dry silk nuclear bacteria, sickle bacteria genera, neat tinynuclear bacteria and 4 species of fusarium oxysporum and one strains of bacteria from fat before respectively 3.58%,5.22%, 3.16%, 7.25%, 3.16% to 2.71% after fat, 1.32%, 1.27%, 3.56%, 1.27%, antagonism effect is obvious;And contrastratio, elongation and compound fertilizer cultivation tomato tomato longitudinal diameter changes significant difference, thetransverse diameter in 8 days after flowering, 18 days after flowering, flower 29 days after elongation change significantdifference, no significant difference 41 days after flowering, tomato yield by 18.2%;And contrast ratio, tomato stem in thewhole stages Jingjifu, bacterial wilt, blight, southern blight disease incidence and disease index fell by 73.69%, 64.99%,40.08%, 73.69% and 78.22%, 74.40%, 30.97%, 74.40%, drug fertilizer joint prevention and control soil borne pathogen antagonismeffect is remarkable, itsbest to stemRhizoctonia pathogenantagonism,worstFusariumoxysporumpathogenantagonism.
