早植烟膜下移栽方式下3种地膜的烤烟产质量效应

目的]为了筛选早植烟膜下移栽方式下适合烤烟的颜色地膜.方法]进行了黑膜、银灰膜和透明膜共3种地膜对烤烟农艺和经济性状效应的田间试验.结果]3种地膜对烟苗的成活率无明显影响;银灰膜下移栽的烟株生育期最短;透明膜覆盖的烟株气候性斑点病显著高于黑膜和银灰膜;产量、产值、上等烟比例,银灰膜和黑膜处理显著高于透明膜.结论]银灰膜较适合于当地早植烟膜下移栽方式.

Yield and Quality Effects of Flue-cured Tobacco of Three Kinds of Plastic Films under Early-planted Film-covered Transplanted Mode

Objective ] The research aimed to select suitable plastic film color of flue-cured tobacco under early-planted film-covered transplan- ted mode. Method ] The field experiment was carried out to study the agronomic characters and economic characters of flue-cured tobacco with black film, Silver grey film and transparent film. Result ] Three kinds of plastic films had no obvious effect on the survival rate of tobacco seed- ling. The growth period of the transplanted tobacco with silver grey film was the shortest. The incidence rate of weather fleck disease of tobacco plant covered with transparent film was significantly higher than the others, The yield,output value and high-grade tobacco ratio of tobacco plant covered with black film and silver grey film were significantly higher than that with transparent film. Conclusion] Silver grey film was the most suitable for film-covered transplanted mode of local early-planted flue-cured tobacco
