烟草生长未达本品种应有高度和叶片数就提前现蕾开花,其烟叶产量和品质会显著下降。挽救措施是:对于早期早花(7—8片叶时开花)植株进行强化打顶,放弃主茎留杈烟在烟株距面6.6—10厘米高处截断主茎,然后在留下部分自上而下的第二张叶腋处保留一个腋芽,加强肥水管理,促其生长。对后期早花(12—13片叶时现蕾开花),要进行轻打顶,即截去烟株顶部3—4张叶,再在留下部
Tobacco growth is less than the height of the species and the number of leaves on the bud in advance blossoming, the yield and quality of its tobacco will be significantly decreased. The rescue measures are as follows: For the early early flowering (7-8 leaves when the flowering) plants to strengthen the top, give up the main stem leave the twig smoke in the plant height of 6.6-10 cm above the truncated stem, and then leave the part from the top Under the second leaf axil leave an axillary buds to strengthen fertilizer and water management and promote its growth. On late late flowering (12-13 leaf buds flowering), to be light topping, that is cut off the top of the tobacco plants 3-4 leaves, and then left in the Department
