铜仁思南示范烟区综合防控技术集成效果初报

Preliminary Report on Integrated Effect of Comprehensive Control Technology in Sinan Demonstration Tobacco Area in Tongren City

本研究以云烟87号为研究材料,在贵州省铜仁市思南县张家寨镇开展土壤保育、蛾类幼虫成虫防控、中后期叶斑类病害防控、基质拌菌及拮抗菌群防技术等应用集成技术研究。结果显示,试验区防治费用较对照区低49.36元/0.067 hm^(2),示范烟区蚜虫相对防效为50.52%,斜纹夜蛾相对防效为42.86%,产量损失率较对照烟区降低0.58%,示范烟区产值损失率较对照烟区低1.01%,均增收87.6元/0.067 hm^(2),因此采用综合防控技术集成技术对该地区烟草病虫害防治具有较好的应用效果。

In this study,Yunyan No.87 is used as the research material to carry out the application integration technology research on soil conservation,moth larva adult control,leaf spot disease control in the middle and late stages,substrate mixed bacteria and antagonistic bacteria group control technology in Zhangjiazhai Town.The results show that the control cost in the experimental area is 49.36 yuan/0.067 hm^(2) lower than that in the control area,the relative control efficiency of aphids in the demonstration tobacco area is 50.52%,the relative control efficiency of Spodoptera litura is 42.86%,the yield loss rate is 0.58%lower than that in the control tobacco area,the loss rate of output value in the demonstration tobacco area is 1.01%lower than that in the control tobacco area,and the income is 87.6 yuan/0.067 hm^(2) higher.Therefore,the integrated technology of comprehensive control and prevention had a good application effect on the control of tobacco diseases and pests in this area.
