干旱胁迫对烤烟早发的影响

Effects of Drought Stress on the Early Rapid Growth of Flue cured Tobacco

采用温室盆栽试验研究了移栽后不同时段的干旱胁迫对烤烟早发的影响。结果表明：烤烟移栽后第１周或第３周干旱严重抑制了烟株早发和旺长。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，而移栽后第２周干旱有利于烤烟早发和旺长。

A pot experiment was conducted to study the effects of drought stress of different time on the early rapid growth (ERG) of flue cured tobacco after transplanting in a greenhouse.It was concluded that the drought in the first or third week after transplanting gravely inhibited the ERG and the drought in the second weed was beneficial to the ERG and vigorous growth of flue cured tobacco. In the flue cured tobacco production,the suitable soil water in the first and third week and the drought in the second week were beneficial to the ERG and vigorous growth of flue cured tobacco.
