[目的]为研究昭通烟区烤烟膜下小苗不同明水移栽方式对烟株生长发育及产质量的影响。[方法]以K326烤烟品种为材料,采用大田试验方法。[结果]处理B(移栽时,待塘水还未全部落完时,用棍打孔,将烟苗根部放入孔内后,用少量细土固定)移栽成活率最高,破膜、掏苗时间和整个生育期提前1 d,能提高烟株的综合农艺性状,还能降低气候性斑点病的发病率及病情指数,一定程度提高产量、产值、上等烟比例等。[结论]该研究可为昭通地区烤烟大田生产提供理论指导。
[Objective] The research aimed to study the effects of transplanting methods of tobacco seedlings on the growth and yield and quality of tobacco plants under the tobacco seedlings under Zhan tobacco field. [Method] With K326 flue-cured tobacco as material, the field test method was used. [Result] When B was transplanted, the survival rate of transplanting was the highest when transplanting, when the ponds to be treated had not been completely finished, stick holes were drilled and the root of tobacco was put into the holes, Seedling time and the whole growth period one day earlier can improve the comprehensive agronomic traits of tobacco plants, but also reduce the incidence and severity of climate speckle disease index, to a certain extent, increase production, output value, superior tobacco ratio. [Conclusion] This study could provide theoretical guidance for the production of flue-cured tobacco in Zhaotong area.
