摘要
设置大田和温室试验，研究水分供应和水分胁迫对烤烟早发的影响。结果表明：移栽后水分供应显著促进烤烟早发；移栽后第１周或第３周干旱严重抑制了烤烟早发；烤烟早发与旺长呈极显著相关。在烤烟生产中，移栽后第１周和第３周保持适宜的土壤水分有利于促进烤烟早发和旺长。
Field and pot orthogonal experiments
were conducted to study effects of water supply and drought stress on early rapid growth(ERG) of
tobacco in 1996-1997.The results indicated that water supply after transplanting significantly
accelerated ERG; drought in the first or third week greatly inhibited ERG; ERG was very
significantly correlated with vigorous growth of the plants.In tobacco production, suitable soil water
in the first and third week was beneficial to the ERG and vigorous growth of tobacco.
