摘要
[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] To study impact of different irrigation-before-transplanting methods on growth,yield and quality of under-film tobacco seedlings in Zhaotong tobacco producing regions.[Method] K326 was taken as the test materials,and field test adopted.[Result] Treatment B （during transplanting,before the pond water dries,punch sticks into mud,then put tobacco roots into the hole and then fix with a little fine soil） had the highest survival rate,film-breaking and seedling take-out timing and the whole growth season was 1 day earlier.Comprehensive agronomic characters of tobacco plants were improved,incidence and disease index of the climatic scab reduced,and yield,output value and ratio of high-quality tobacco leaves were improved.[Conclusion] The study offers theoretical instructions for the field production of tobacco plants in Zhaotong area.
