Embodiment 1

[0020] Embodiment 1: traditional transplanting method

[0021] Traditional transplanting methods include the following steps:

[0022] (1) Ridging and fertilizing: Before transplanting, prepare the ridges before transplanting, and apply tobacco-specific basal fertilizer and bio-organic fertilizer as basal fertilizers on the bottom of the ridge. 120cm×45-55cm;

[0023] (2) Cover film: cover the ridge body with plastic film after ridge preparation;

[0024] (3) Tobacco seedling transplanting: Use a punching machine to punch holes for transplanting; the tobacco seedlings are 60-70 days old, the stem height is 8-15cm, and the stem circumference is 2.2-2.5cm. ;

[0025] (4) Management after transplanting: 25-30 days after transplanting, remove the mulch film, topdress tobacco-specific topdressing fertilizer and potassium sulfate, and cultivate soil in intertillage.

Embodiment 2

[0026] Embodiment 2: Conventional pit type transplanting method

[0027] Conventional pit type transplanting method comprises the following steps:

[0028] (1) Ridging and fertilizing: Before transplanting, prepare the ridges before transplanting, and apply tobacco-specific basal fertilizer and bio-organic fertilizer as basal fertilizers on the bottom of the ridge. 120cm×45-55cm;

[0029] (2) Covering film: cover the ridge body with plastic film after ridge preparation;

[0030] (3) Tobacco seedling transplanting: Use a punching machine to make a well pit, use a puncher with a diameter of 8-10 cm, and punch holes upright on the ridge body. The well mouth is round, with a diameter of 8-9 cm and a depth of 18 -20cm, the upper 11-13cm of the well cellar is cylindrical, and the lower 6-8cm is conical; the tobacco seedling age is 60-70 days, the stem height is 8-15cm, the stem circumference is 2.2-2.5cm, and the tobacco is poured once on the day of transplanting Special fertiliz...

Embodiment 3

[0032] Embodiment 3: seedling transplanting method under conventional film

[0033] The seedling transplanting method under conventional film comprises the following steps:

[0034] (1) Ridging and fertilizing: Before transplanting, prepare the ridges before transplanting, and apply tobacco-specific basal fertilizer and bio-organic fertilizer as basal fertilizers on the bottom of the ridge. 120cm×45-55cm;

[0035] (2) Tobacco seedling transplanting: manual digging and transplanting; the tobacco seedling age is 40-45 days, the stem height is 3-4cm, and 4-6 true leaves are poured once on the day of transplanting to fix the roots with special fertilizer for raising seedlings;

[0036] (3) Mulching film: Cover the ridge body with plastic film after transplanting;

[0037] (4) Management after transplanting: 15-20 days after transplanting, when the film is on the top of the tobacco seedlings, tear off the plastic film in time to introduce seedlings; 25-30 days after transplanting...

Abstract

The invention discloses an under-film kiln-type transplantation method for tobacco seedlings. The method comprises the following steps of ridging fertilization, film covering, tobacco seedling transplantation, sealing film covering and transplantation after-management. According to the method, a technology of film covering, transplantation and sealing film covering in sequence is applied to a flue-cured tobacco seedling transplantation method for the first time, in the period, at low temperature, not suitable for flue-cured tobacco seedling transplantation, tobacco seedling transplantation canbe conducted, the transplantation period of flue-cured tobacco can be advanced, the transplantation survival rate is increased, early growth and quick sprouting of tobacco plants are promoted, and the uniformity of the tobacco plants in a large field is improved; the yield and output value of the tobacco are increased, the seedling raising period is shortened, the seedling raising cost is reduced, and the income of tobacco growers is increased.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a cellar-type tobacco seedling transplanting method under a membrane. Background technique [0002] Nowadays, planting tobacco seedlings deep in high ridges has become the consensus of everyone. The cultivation technology of plastic film mulching has formed a relatively complete technical system. The effects of heat preservation, water retention, fertilizer retention, and weed growth inhibition have played a positive role in improving the quality and efficiency of flue-cured tobacco production, and are accepted by the majority of tobacco farmers, and the promotion area is increasing year by year. However, due to the differences in climate and soil conditions in different tobacco leaf producing areas, some restrictive production technology problems have appeared in many tobacco areas in actual production, such as long seedling cultivation period, transplanting period is g...
