The invention discloses a
flue-cured tobacco
open field culture round hole type
transplanting method. The method comprises the following steps: (1) carrying out
land preparation, ditching, applying a basic
fertilizer and ridging; (2) carrying out
punching to form round holes on
ridge bodies by adopting a puncher; (3) vertically placing the tobacco seedlings into the round holes in a mode that roots are downwards to carry out
transplanting; (4) sprinkling root fixing water in which a
seedling improvement
fertilizer is dissolved along the hole walls and at the same day, spraying a
pesticide; and (5) after
transplanting seedlings for 3 to 5 days, checking and supplementing the seedlings, applying an additional
fertilizer after 10 days, filling the round holes after 15 days, earthing to ditches until
ridge bodies are full after 35 days, and then entering the management stage. The method has the following advantages that 1, the transplanting round holes have small diameters so as to cause low damage to the
ridge bodies and a mulched
plastic film; 2, the method has no compressing effect on soil in the holes; 3, tobacco
seedling transplanting efficiency is improved; 4, the tobacco seedlings are promoted to early grow and quickly
tiller and growth neatness of the tobacco seedlings is improved; and 5, the method is simple to operate and is easy to popularize. The method is suitable for planting
flue-cured tobacco.
