Embodiment

[0019] The present invention is a flue-cured tobacco seedling raising method with shallow water, ventilation in advance and seedling hardening, which is improved on the basis of the floating seedling raising method. The depth of the liquid water is 2.5-3.5cm; when the tobacco seedlings have 4 true leaves, drain and harden the seedlings. The time of hardening is until the leaves of the tobacco seedlings wilt at noon, and it is advisable to recover sooner or later. After hardening, add water and add 180 to the floating plate. g / 48 trays (take the 160-hole size seedling tray as an example), and at the same time open the sides of the seedling shed to 1 / 5 to 1 / 3 for ventilation when the temperature is high during the day; When crossing, add 180g / 48 trays of fertilizer again, and open both sides of the seedling shed to 1 / 3 to 1 / 2 for ventilation when the temperature is high during the day; Once hardening the seedlings, the method is the same as the first time.

Abstract

The invention discloses a flue-cured tobacco seedling cultivating method adopting modes of shallow water, ventilation in advance and seedling hardening. On the basis of an existing flue-cured tobacco seedling float-breeding method, seedling cultivation is improved, and the depth of seedling cultivating nutrient solution water is from 2.5 cm to 3.5 cm; when tobacco seedlings grow into the large-cross stage and reach the grown-up seedling standard, water is drained for hardening the seedlings; when the seedlings grow to the small-cross stage, the two sides of a seedling cultivating shed are opened to the one fifth-one third portion from the bottom to the top in the day for ventilating; when the seedlings grow to the large-cross stage, the two sides of the seedling cultivating shed are opened to the one third-one second portion from the bottom to the top for ventilating in the day. On the basis of seedling float-breeding, the seedling cultivating modes of shallow water and ventilation in advance are adopted for being beneficial for saving fertilizer, enabling the seedlings to be strong and promoting roots, mosses can be effectively prevented and treated, the disadvantage that the transplanted tobacco seedlings are excessively large or small due to the high or low temperature can be effectively relieved for the cultivated young seedlings, and the method is particularly suitable for cellar type transplantation.

Description

technical field [0001] The invention relates to a flue-cured tobacco seedling raising method using shallow water, ventilation in advance and seedling hardening, and belongs to the technical field of flue-cured tobacco seedling raising cultivation and application. Background technique [0002] Flue-cured tobacco floating seedling cultivation, as a factory-like tobacco seedling method, has the advantages of fast seedling growth and reduced labor intensity. At the same time, the cultivated tobacco seedlings have the characteristics of good uniformity, well-developed root system, and short return time after transplanting. . Flue-cured tobacco floating seedling raising technology has been vigorously promoted since it was introduced into my country in the 1980s, and has achieved great benefits in the flue-cured tobacco intensive seedling raising technology. [0003] The flue-cured tobacco well-pit seedling transplanting technique is to use a special well-drilling device to drill ...
