番茄连作大棚土壤消毒与改良措施研究

Study on Soil Disinfection and Improvement Measures in Greenhouse for Continuous Tomato Cropping

研究高强度利用下设施内番茄连作土壤消毒与改良措施,通过高温闷棚、石灰消毒、大水漫灌和有机肥平衡施肥,实现大棚土壤持续利用。结果表明,石灰消毒+高温闷棚+大水漫灌处理对番茄开花期和结果期农艺性状指标、产量和产值均影响明显,配合使用生物菌肥经济效益最大,且可有效改善土壤养分状况,实现土壤改良与长效利用。

The soil disinfection and improvement measures of tomato continuous cropping under high-intensity utilization were studied.Through high-temperature closed shed,lime disinfection,flood irrigation and balanced fertilization of organic fertilizer,the sustainable utilization of greenhouse soil was realized.The results showed that the treatment of lime disinfection+high temperature closed shed+flood irrigation had a significant impact on the agronomic indexes,yield and output value of tomato in the flowering and fruiting period.The economic benefit of using biological bacterial fertilizer was the largest,and it could effectively improve the soil nutrient status,also achieve soil improvement and long-term use.
