肥料和农药协同作用防治烟草根结线虫病研究

摘要

Synergism between pesticide and fertilizer in controlling root-knot nematode was investigated by field randomized block test. The results showed that the best control efficiency was shared by 0.5% abamectin and 25% mixed pesticide (abamectin and carbosulfan), 24.1% and 28.0% , respectively. The positive effect was found by synergism between pesticide and fertilizer in controlling root-knot nematode. The economic benefit and agricultural benefit were gained by controlling root-knot nematodes. The results suggested that the agricultural and ecological benefit could be gained through the integration of agricultural practice and chemical technology in controlling root-knot nematode.%[目的]为烟草根结线虫病防治提供一种新的思路和方法.[方法]通过田间随机区组试验,探讨农药和肥料协同对烟草根结线虫病的防效.[结果]研究发现,0.5%阿维菌素颗粒剂和25%阿维·丁硫水剂的防效显著,防效分别是28.0%和24.1%,有机肥 、 无机复合肥与0.5%阿维菌素颗粒剂协同作用可以增强阿维菌素的防效,减轻根结线虫对烤烟生长的影响,提高烤烟产量和质量,增加烤烟收益.[结论]在烤烟生产上整合农业措施和化学防治具有积极的生产和生态意义.
