The invention belongs to the technical field of
flue-cured tobacco
seedling raising, and particularly relates to a dry-wet alternating
flue-cured tobacco
seedling raising method suitable for northeast regions. Selecting a leeward and sunny place as a
seedling raising field, building an
overwintering warm shed as a seedling raising shed, and arranging a reservoir in the seedling raising shed so as to improve the temperature of water for seedling raising; a plurality of nursery ponds are manufactured in the nursery shed, the bottoms of the nursery ponds are flat, and the nursery ponds are filled with nursery water in the reservoir; putting the seedling raising tray filled with the
flue-cured tobacco seeds into a seedling raising pond; the seedling raising
greenhouse is ventilated every day, and in the seedling raising process, the seedling raising pond is subjected to multiple times of treatment 1 and then subjected to multiple times of treatment 2 till 7-10 days before
transplanting;
disease-resistant treatment is conducted, topdressing is conducted three times in the seedling raising period,
seedbed fertilizer and water are
cut off 7-10 days before
transplanting, water control and seedling hardening are conducted, and flue-cured tobacco seedlings are transplanted into a field for planting; according to the method, a dry-wet alternating environment of the seedling
bed is created, so that the effect of hardening seedlings and raising seedlings at the same time can be achieved, and
moss can be reduced.
