The Round Hole Transplanting Method of Flue-cured Tobacco in Open Field Cultivation

Abstract

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.

Description

technical field [0001] The invention belongs to a flue-cured tobacco cultivation method. Background technique [0002] At present, flue-cured tobacco planting mainly adopts the method of first growing seedlings and then transplanting. There are mainly two ways of raising seedlings: floating seedlings and tray wet seedlings. Both adopt the soilless cultivation technology in the principle of plant nutrition, and replace the natural soil with the seedling substrate. When growing seedlings, use expanded polystyrene grid trays to fill the matrix and sow tobacco seeds on the matrix, then float the sown seedling trays in the seedling pools containing nutrient solution or keep the seedling trays moist to complete the germination, growth and development of tobacco seedlings. Seedling process. Transplanting is an important technical link in the production of flue-cured tobacco. The known method of transplanting flue-cured tobacco is to first form a ridge, then make a nest on the rid...

Problems solved by technology

But this kind of transplanting method is only suitable for transplanting flue-cured tobacco seedlings, and the diameter of the hole is large, which will cause great damage to the ridge.

In addition, if there is heavy rain after transplanting, the tobacco seedlings planted in the hole will be damaged due to flooding
