Problems solved by technology

[0006] In order to solve the shortcomings of the existing flue-cured tobacco floating seedling cultivation method, the tobacco seedlings have few root hairs, poor root activity, poor adaptability to drought stress, and slow seedling growth. The present invention provides a method for raising flue-cured tobacco seedlings by floating and wet.

Embodiment 1

[0026] Embodiment 1, a kind of flue-cured tobacco bleaching wet seedling raising method, comprises the following steps:

[0027] (a) Sowing: In the seedling shed, the coated seeds of flue-cured tobacco are broadcast live in the seedling holes filled with the matrix on the seedling tray 1, and the matrix is ​​covered until the seeds are slightly exposed;

[0028] (b) floating nursery stage: if figure 1 As shown, the seedling tray 1 after sowing is floated in the seedling pond 2 filled with the nutrient solution 3, and through measures such as abundant water (generally, the water depth is controlled at about 8 centimeters), heat preservation, etc. high.

[0029] (c) Leaf cutting for the first time: when the tobacco seedlings grow to seven leaves and one heart, the tobacco seedlings are cut for the first time. At this time, the stem height of the tobacco seedlings is 4-5 cm;

[0030] (d) Shallow water nursery stage: if figure 2 As shown, to reduce the draft of the seedling tr...

Abstract

The invention provides a flue-cured tobacco afloat and moist seedling raising method, and relates to a seedling raising method combining a moist seedling raising method and an afloat seedling raising method. The invention provides the flue-cured tobacco afloat and moist seedling raising method aiming at solving the disadvantages of less root hair, poor root activity and slow seedling restoration of the existing flue-cured tobacco afloat seedling raising. The method comprises the following steps: seeding, an afloat seedling raising phase, primary leaf clipping, a shallow water seedling raising phase, a moist seedling raising phase and seedling hardening. The flue-cured tobacco afloat and moist seedling raising method can cultivate sound tobacco seedlings with developed root hair, strong stem toughness and high stems without seedling restoration time basically, and is beneficial to realizing seedling raising technique normalization and seedling quality standardization, can reduce the disease infection and lower the production cost.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco seedling cultivation, in particular to a seedling cultivation technology combining a wet seedling cultivation method and a floating seedling cultivation method. Background technique [0002] The existing flue-cured tobacco seedling raising methods have gone through three stages: nutrient bag seedling raising, wet seedling raising, and floating seedling raising. At present, floating seedling raising is widely promoted. The comparison of the above three seedling raising methods is as follows: [0003] Nutrient bag seedling cultivation: labor-saving, time-saving, simple operation, well-developed root system and strong tobacco plants, but this method is not suitable for large-scale industrial seedling cultivation and commercial seedling supply; [0004] Wet seedling cultivation: The root system of the tobacco seedlings is drought rooting, the root system is developed, and the number of leaf...
