Seedling raising device for seedling hardening

Abstract

The invention discloses a seedling culture device for seedling hardening. The seedling culture device comprises a plurality of seedling culture pools, a plurality of seedling culture trays, a plurality of lifting plates, a plurality of first water pipes, a waste liquor pool, a second water pipe, a third water pipe and a plurality of fourth water pipes, wherein the seedling culture pools are arranged at intervals in a line-shaped mode from the head end to the tail end, the two opposite side walls of every two adjacent seedling culture pools are each provided with a groove set, the seedling culture trays are arranged at the tops of the seedling culture pools, a plurality of seedling culture cups are arranged on the seedling culture trays at intervals, and the first water pipes are arranged between the two opposite side walls of every two adjacent seedling culture pools. The seedling culture device can adjust dry and wet conditions of the growth environment of seedlings fast according to needs, the depth of nutrient solutions in the seedling culture pools can be adjusted accurately, the nutrient solutions can be replaced conveniently, automatic control is adopted in the device, and labor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation. More specifically, the present invention relates to a seedling raising device for hardening seedlings. Background technique [0002] Floating seedling raising technology is a soilless seedling raising technology. In greenhouses, plastic greenhouses and small sheds, the filling matrix is ​​placed on polystyrene seedling trays, seeds are sown, and the seedling trays are placed in complete nutrient solution after sowing. In the water tank, let the seeds germinate, grow, and become seedlings. In floating seedling cultivation, the seedlings are soaked in the nutrient solution for a long time, and it will be difficult to adapt to the relatively dry environment after being suddenly transplanted to the field, so the seedlings need to be hardened separately before transplanting. [0003] The existing seedling raising devices for seedling hardening cannot quickly achieve the alternation of dry ...

AI Technical Summary

Problems solved by technology

Floating seedlings have seedlings soaked in nutrient solution for a long time, and it will be difficult to adapt to a relatively dry environment after being suddenly transplanted to the field. It is necessary to harden the seedlings separately before transplanting

[0003] The existing seedling raising devices for seedling hardening cannot quickly achieve the alternation of dry and wet according to the needs, nor can it accurately adjust the depth of the nutrient solution according to the needs, and it is not convenient to replace the nutrient solution. Therefore, it is necessary to provide a device that can take advantage of floating seedlings. A seedling raising device for hardening seedlings that can overcome its defects
