摘要
为探明井窖式移栽不同栽植深度对烟株前期生长发育的影响,在贵阳龙岗基地开展了田间试验。结果表明,移栽后35 d,烟苗生长点距井窖口6 cm处理烟株农艺性状表现最好,生物量、根系活力最高,根系发育最好,综合效应系数最大。井窖式移栽适合的栽植深度以烟苗生长点距井窖口6 cm最为适宜,有利于烟株前期地上部生长、根系发育及干物质积累。
Field experiments were conducted in Longgang base,Guiyang to study the effects of different planting depth well cellar-type transplanting on the early growth and development of tobacco. Results showed that 35 d after transplanting, the treatments of tobacco growing point from 6 cm of well cellar mouth had the best agronomic traits with the highest biomass and root vigor, the best root development and the biggest comprehensive effect coefficient. The tobacco growing point from 6cm of well cellar mouth was most appropriate for well cellar-type transplanting planting depth, beneficial to early growth,root growth and dry matter accumulation of tobacco.
