黑麦草对烤烟的掩青效应研究

Study on Incorporation of Lolium multifolrum on Flue-cured Tobacco

试验结果表明:采用黑麦草作为掩青绿肥,3月20日掩青、中期揭膜处理的烟株生长速度、最终长相及产量、产值均优于常规盖膜栽培,产量和产值最高,分别为2323.5 kg/hm2和21224.25元/hm2。此外,绿肥同时有抑制黑胫病和赤星病发生的作用。

The result showed that Lolium multifolrum incorporation and removing film in middle growth period were conducive to the growth of tobacco, appearance, yield and output value. The yield and output value in the treatment of incorporation on March 20th ＋ removing the film were the highest, which were 2323.5 kg/hm^2 and 21224.25 yuan/hm^2 respectively. Further, Lolium multifolrum incorporation could develop the anti -disease ability to black shank and brown spot.
