Pressure-driven lift seedling culture bed

Abstract

The invention relates to a seedling culture bed, in particular to a pressure-driven lift seedling culture bed, belonging to the technical field of seedling culture.Traditionally, an overhead seedling culture bed is employed for seedling culture, which is not conducive to root generation of the seedlings at the early stage but also consumes a lot of water; the seedlings can also be cultured on a ground seedling culture bed; although the practice is conducive to root generation of the seedlings and water conservation, the problems such as mutual interspersing of root systems, root segment mildew and the like are easily caused. Multiple lifters of the seedling culture bed are arranged at the same underground horizontal plane, piston connecting rods of the lifers serve as support columns of a seedling culture bed frame and are connected with connecting cylinders of the seedling culture bed frame to form the pressure-driven lift seedling culture bed. Water or gas is used as the transmission stress of the lifters; in particular, water from a nursery garden water supply system is used as the transmission stress to lift the seedling culture bed, thus simplifying the fabrication process of the pressure-driven lift seedling culture bed. by using the seedling culture bed in the invention, the problem that the existing seedling culture bed is confined in application in the process of culturing seedlings is solved, thus being applicable to different seedlings and enabling seedling culture at different seedling culture time periods.

Description

Technical field: [0001] The invention belongs to the technical field of seedling cultivation, and relates to a seedling raising bed, in particular to a pressure lifting type seedling raising bed. Background technique: [0002] At present, my country's modern container seedling raising technology has gradually changed from the traditional soil as seedling substrate and small-area seedling raising mode to light substrate seedling raising and intensive and large-scale seedling raising. Due to the excavation of a large amount of soil as the seedling substrate, serious damage to the environment has been caused, and because the soil substrate is heavy, it is difficult to afforestation in the mountains, and the transportation cost of the seedlings is increased. In order to solve the above problems, it has become the development trend of today's container seedlings to use light substrates instead of soil as container seedling substrates. However, the use of light substrates as cont...

AI Technical Summary

Problems solved by technology

However, the appearance of rainy weather is uncertain. When the seedlings are placed on the elevated seedling bed for a period of time to eliminate mildew, in order to keep moisture and save water, the seedlings are moved to the ground again, which consumes a lot of labor.

Using a large amount of labor to switch between air root cutting, moisturizing and water saving, and eliminating mildew will eventually lead to an increase in the cost of seedling cultivation

[0003] To sum up: the use of elevated seedbeds for seedling cultivation is not conducive to the rooting of seedlings in the early stage, and the water consumption is too large

Putting seedlings on the ground is good for seedlings to take root, but it is prone to interpenetration of seedling roots and root mildew.
