摘要
为探明麻栗坡县根茎类病害高发山区中,不同的垄体覆盖方式与烟草根茎类病害发生的相关性,以及不同覆盖方式下的经济效益差异,通过小区试验,对3种不同覆盖方式下烤烟的长势、抗病性、经济效益等进行了研究。结果表明:在秸秆覆盖、地膜覆盖、秸秆地膜双覆盖3种垄体覆盖方式中,秸秆覆盖具有抗病和促进生长的作用,但单纯覆盖秸秆不足以取代地膜覆盖作为保水保肥措施,秸秆地膜双覆盖有利于促进烟株生长,提升烤烟对根茎类病害的抵抗力,最终有助于提升烟叶产量和质量。
In order to find out the correlation between different ridge cover modes and tobacco rhizome diseases in the mountainous area with high incidence of rhizomatous diseases in Malipo County and the difference of economic benefits under different cover modes the growth disease resistance and economic benefit of flue-cured tobacco under three different cover modes were studied by plot test.The results showed that straw mulching could resist disease and promote growth but straw mulching was not enough to replace mulching as a measure to keep water and fertilizer.
