Example Embodiment

[0018] Embodiment: The round hole transplanting steps of flue-cured tobacco open field cultivation are as follows:

[0019] (1) 7-10 days before the transplanting of flue-cured tobacco, arrange the tobacco planting field, open the box according to the ridge distance of 110cm, and apply decomposed farmyard manure or / and fermented cake fertilizer or / and compound fertilizer as base fertilizer along the center line of the ridge bottom. The ratio of the total fertilizer application amount is: 85% of the total nitrogen application amount and potassium application amount, and 100% of the total phosphorus application amount; then ridges are raised, the height of the ridge body is 20-25cm, the width of the ridge bottom is 80-85cm, and the ridge body is full and arc-shaped. Type, the ridge surface is flat and finely divided;

[0020] (2) Use a foot-operated hole puncher to make round holes on the ridge body. The hole distance of the round holes is 55cm, and the diameter of the round hol...

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 seedling and then transplanting. The seedlings are mainly raised in two ways: floating seedlings and tray-wet seedlings, both of which use the soilless culture technology in the principle of plant nutrition, and replace the natural soil with the seedling matrix. When raising the seedlings, the expanded polystyrene grid is used to fill the substrate and then the tobacco seeds are sown on the substrate, and then the seedling tray after sowing is floated in the nursery pond containing the nutrient solution or the nursery tray is kept moist to complete the germination, growth and development of the tobacco seedlings. Seedling process. Transplanting is an important technical link in the production of flue-cured tobacco. The well-known method of transplanting flue-cured tobacco is to make ...
