本研究在设施条件下，评估了综合使用秸秆还田和生防菌技术对设施番茄连作土传病害的防治效果及增产作用。研究表明：1）秸秆还田技术有利于温室内 CO2积累，比常规温室 CO2的含量普遍高200～400μL?L?1，同时能够提高地温0.5℃；2）分别单独使用2个生防菌、单独使用秸秆还田技术和2项技术集成使用的5个处理中，生防菌PTS394＋秸秆综合处理效果最好，株高和茎粗分别比常规增加达到35.9%和20.9%，理论产量达9302.7 kg·667 m?2；3）土传病害防效调查显示，生防菌PTS394＋秸秆和B1619＋秸秆2个综合处理防效最好，分别为68.0%和66.2%。基于理论产量、市场番茄价格及投入成本情况，最终计算得出综合应用生防菌 PTS394和秸秆还田技术处理的理论亩纯收益最高，为23071元，番茄效益增收达41.7%。本研究为生防菌和秸秆还田技术在田间的综合使用提供了理论基础。

The control efficiency of tomato soil-borne diseases and yield increasing were evaluated under the integrated application of straw returning and biocontrol agent. The results showed that: 1) Straw returning was conducive to the accumulation of CO2, and CO2 content increased 200-400 μL?L?1 compared with control greenhouse. In the meanwhile, the ground temperature increased 0.5 ℃ in the straw returning treatment. 2) Among the five treatments (including PTS394, B1619, straw returning, PTS394+straw and B1619+straw), the PTS394+straw treatment exhibited excellent effect, plant height and stem diameter increased 35.9%and 20.9%respectively compared with control, and the theoretical yield was about 9302.7 kg?667 m?2. 3) The field experiment revealed that PTS394+straw and B1619+straw were the best for the control of soil-borne diseases, the control efficacies were 68.0%and 66.2%, respectively. The results showed that the economic benefit of PTS394+staw is about 23071 Yuan. This study provided a theoretical basis for the integrated application of biocontrol agent and straw returning in the field.
