A combined floating seedling tray

Abstract

The invention discloses a combined floating seedling growing plate comprising a seedling tray and a holder tray; the seedling tray comprises a plurality of seedling holes connected through openings; the cavity bottom wall of the holder tray is provided with a plurality of protrusions matched in positions with the seedling holes; the protrusion is provided with a receive cavity matched in shape with the bottom of the seedling hole; the bottom of each receive cavity is provided with a water hole; in applications, the seedling tray is buckled on the holder tray, and the bottom of each seedling hole inserts the opening of the receive cavity; the seedling tray and the holder tray are matched in structures; the holder tray can increase the displacement of the whole seedling growing plate, can improve the seedling growing plate buoyancy, and can realize the floating function of the whole seedling growing plate; in addition, the bottom of the seedling hole inserts the opening of the receive cavity, and the receive cavity can well fix the seedling hole, thus increasing the seedling tray intensity.

Description

technical field [0001] The invention relates to a combined floating seedling raising tray, which belongs to the technical field of tobacco seedling raising devices. Background technique [0002] In tobacco production, tobacco seedlings are basically cultivated in the way of floating seedlings. Floating seedlings are to float the plugs equipped with seedling substrates on the water surface. A seedling raising method that absorbs water and nutrients in the middle. The device used in the seedling raising work is the seedling raising floating tray. In the process of growing flue-cured tobacco seedlings and field planting, a large amount of plastic films are used (seeding greenhouse film, seedling greenhouse cover film, seedling pond bottom film and field planting film). Among these plastic films, except for the seedling greenhouse film which can be reused for about 5 years, the rest of the plastic films are disposable. If the used plastic mulch, especially the mulch used in f...

AI Technical Summary

Problems solved by technology

If the used plastic mulch, especially the mulch used in field planting, is not recycled and reprocessed, it will cause serious pollution to the agricultural production soil and the rural environment.

At the same time, because the existing floating seedling trays are made of light, blister-resistant, and corrosion-resistant polystyrene plastic foam, they are difficult to decompose in the field. At present, there is no effective recycling and reprocessing method. The environment has caused obvious pollution, and it is urgent to find a good alternative product

[0003] At present, the waste plastic film after recycling is usually used to process seedling trays on tobacco. However, due to the structure of the seedling tray and the density of the plastic mulch, the floatability of the seedling tray processed by plastic mulch is poor, and it cannot Ensure the draft of its floating on the water surface, thus affecting the quality of floating seedlings
