Greenhouse seedling raising rack

Abstract

The invention provides a greenhouse seedling raising rack. A supporting frame is provided with plurality of layers of fixing plates and accommodating grooves in an erected mode and is provided with built-in seedling raising trays. Driven teeth are arranged on the outer side of the seedling raising trays, through holes are formed in one side of each fixing plate, and rotary shafts penetrate into the through holes. The rotary shafts are connected with a driving motor. Gears meshed with the driven teeth are arranged on the rotary shafts. The seedling raising trays are provided with top plates, base plates and water supply cavities between the top plates and the base plates, and the water supply cavities are connected with feed water inlet pipes. A plurality of planting holes are formed in the top plates, planting grooves are formed in the top plates, and the lower ends of the planting grooves are located in the water supply cavities. Clamp-connecting parts are arranged on the inner walls of the planting grooves, filter plate bodies are clamp-connected to the clamp-connecting parts, and the planting grooves are divided into seedling raising zones and conduction zones. A conduction medium is contained in the conduction zones. Seedling raising loop sleeves are arranged in the seedling raising zones, and a seedling raising medium is contained in the seedling raising loop sleeves. A plurality of air guiding holes are formed in the side walls of the seedling raising zones and are communicated with the seedling raising zones and the water supply cavities, and the lower ends of the water supply cavities are connected with drainage pipes. The greenhouse seedling raising rack can ensure moisture content during seedling raising and transplantation and makes lighting uniform.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a greenhouse seedling raising frame. Background technique [0002] Plug seedling cultivation is a mature advanced agricultural technology that has emerged with the rapid development of modern agriculture, agricultural scale management, specialized production, mechanization and automation. It is an advanced production method to mass-produce high-quality seedlings under the best environmental conditions created artificially, using scientific, mechanized, and automated technical measures and means. Compared with the traditional seedling raising method, the hole tray seedling raising technology has the advantages of using less seeds and occupying a small area; it can shorten the seedling age and save seedling raising time; it can reduce the occurrence of diseases and insect pests as much as possible; it can improve seedling raising production efficiency and reduce costs; it is ...

AI Technical Summary

Problems solved by technology

[0006] The present invention proposes a greenhouse seedling raising frame, which solves the problems in the prior art that the seedling raising device needs to monitor the soil water content at any time, the seedlings are easily damaged during the transplanting process, and the uniformity of seedling raising is poor.
