摘要: 烤烟NC89、LJ851、LJ911伸根期的生长中心在地下部分。合理地控制土壤水分含量,协调地上部分和地下部分的生长是此期生产管理的重要环节。土壤相对含水量在75%~85%的光合速率最高,但水分利用效率最高的土壤相对含水量在65%~75%之间,且此土壤水分含量有利于烤烟烟苗的蹲苗、壮苗,是烤烟生长的最佳土壤水分条件。

Abstract: The flue-cured tobacco growth of NC89、LJ851、LJ911 focus mainly on subterranean part in the root extending stage. It is important element of production management to control soil water content reasonably and harmonize growth between root and stem at this stage. Photosynthesis rate reaches peak when relative soil water is at 75%~85%, yet water use efficiency peak value is at 65%~75% that is in favor of tobacco seedling strong growth.

Key words: flue-cured tobacco, water stress, photosynthesis rate, respiration rate, transpiration rate, water use efficiency
