Embodiment 1

[0031] Such as Figure 1-6 Shown: a combination of shallow water trays for flue-cured tobacco seedlings, including a serving tray 1 and a seedling tray 2, wherein the serving tray 1 has a cuboid shallow groove structure and at least two seedling trays 2 can be placed in each serving tray 1, and the serving tray 1 The middle position of each upper edge is provided with a grasping groove 3, the seedling raising tray 2 has a rectangular structure as a whole, the middle position of each upper edge of the seedling raising tray 2 is provided with a grasping groove 3, and the lower side of the seedling raising tray 2 is provided with a matrix arrangement of seedling raising grooves 4. The seedling-raising tank 4 has a four-corrugated terrace structure with a large top and a small bottom. The thickness of the bottom surface of the seedling-raising tank is set to 10 mm, and a water-absorbing hole 5 is arranged in the middle of the bottom of the seedling-raising tank. The lower edge of t...

Abstract

The invention relates to a shallow water tray combination and a cultivating method of the shallow water tray combination, in particularly relates to the shallow water tray combination for tobacco seedling cultivating and the cultivating method of the shallow water tray combination. The shallow water tray combination for the tobacco seedling cultivating comprises holding trays and seedling trays, wherein each holding tray is of a cuboid shallow water slot structure; at least two seedling trays are placed in each holding tray; a grabbing groove is formed in the middle position of each upper edge; the grabbing groove is formed in the middle position of each upper edge of each seedling tray; a water adsorbing hole is formed in the middle position of the bottom face of each seedling tray; a cambered chamfer is arranged at the lower edge of each water adsorbing hole; a semicircular notch is formed in the middle position of each edge at an upper bore of a seedling slot. The seedling cultivating method comprises seven steps, wherein after a culture solution in each holding tray is basically dried, the culture solution is added to 1 / 4 height of the holding tray, and the step is performed repeatedly in sequence. The shallow water tray combination and the cultivating method thereof have the beneficial effects that the root systems of the cultivated tobacco seedlings are well-developed, and tobacco seedlings are high in overall quality and strong in stress resistance; after being planted into big fields, the tobacco seedlings adapt to the external environment fast; the seedling returning and growing speed is fast.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a shallow water tray combination and a cultivation method thereof, in particular to a shallow water tray combination for flue-cured tobacco seedling cultivation and a cultivation method thereof. Background technique [0002] In recent years, flue-cured tobacco seedling raising technology in my country's tobacco areas has been continuously updated and developed, from simple tray seedling raising in the past to floating seedling raising, and its intensification and technological level have been continuously improved. These new seedling raising techniques have played a very important role in improving seedling quality and disease prevention. However, with the popularization and application of large areas, there are some problems and deficiencies in both simple tray seedling cultivation and floating seedling cultivation. The method of spraying water on the t...
