烤烟大田地膜点种对烟苗生长发育的影响

Effect of Field Plastic Film Dibbling Seeding on Growth and Development of Flue-cured Tobacco

进行了烤烟地膜点种与常规育苗对比试验研究 ,结果表明 ,地膜点种有利于培育地上茎叶和地下根系协调生长的壮苗 ,简化烟草生产的育苗移栽环节 ,降低移栽运苗劳动强度 ,大田烟苗生长速度快 ,但成苗前的管理不如常规育苗方便 。

The comparing experiment of in field plastic film dibbling seeding and routine seeding of flue cured in 2001 showed that the field plastic film dibbling seeding was helpful to cultivating strong seedling which is coordinating in stem,leaves and roots. It also can simplify the process of tobacco seedling transplanting and reduce the labour intensity of seeding transplanting and seedling transporting and make tobacco seedling grow quickly in field. Although the management of seedling is not as convenient as the routine management,it can be solved through corresponding technological measure.
