高温闷棚配施土壤活化修复杀菌剂对设施番茄连作障碍的影响

Effect of applying soil activation and remediation fungicide in high temperature and stuffy shed on continuous cropping obstacles of protected tomato

采用随机区组试验设计,研究了高温闷棚后施用不同土壤活化修复杀菌剂对设施番茄连作障碍的影响。结果表明,处理1和处理2番茄株高均显著高于对照,处理2单果质量显著高于对照,与对照相比,处理2单果质量提高15.82%,667 m^(2)产量增加了2518.79 kg,增产率达28.03%。与仅使用高温闷棚技术解决设施番茄连作障碍问题相比较,高温闷棚后,施用土壤活化修复杀菌剂可有效改善设施番茄连作障碍问题,改善番茄长势,增加产量,且有效延迟根结线虫侵入番茄根部,延缓番茄根部病害的发生,降低番茄病害发生的程度,可在设施番茄生产上推广应用。

In order to study the effect of applying different soil activation and remediation fungicides on the problem of continuous tomato cropping obstacles after high temperature and stuffy sheds,a completely randomized experimental design was carried out in this research.The results showed that the plant height of treatment 1 and treatment 2 was significantly higher than that of the control;and the single fruit weight of treatment 2 was increased by 15.82%,the yield per 667 m^(2) was increased by 2518.79 kg,and the yield increase rate reached 28.03%,which was significantly higher than the control.The results demonstrated that compared with using only the high-temperature stuffy shed technology,,the application of soil activation and repair fungicide after the high-temperature stuffy shed could effectively improve the problem of continuous tomato cropping in facilities,improve the growth of tomatoes,increase the yield,and effectively delay the invasion of root-knot nematodes into tomato roots,delay the occurrence of tomato root diseases,and reduce the extent of tomato disease.It can be promoted and applied in facility tomato production.
