Seedling culture system

Abstract

The invention belongs to the technical field of agricultural production equipment, and particularly relates to a low-shed ebb-and-flow irrigation seedling culture system which comprises a heat preservation shed and an ebb-and-flow seedling bed laid in the heat preservation shed, the ebb-and-flow seedling bed comprises a conveying device and a liquid storage tray, the conveying device is arranged along the length direction of the heat preservation shed and can convey nursery trays into the liquid storage tray from one end of the heat preservation shed, and the nursery trays in the liquid storage tray can be conveyed to one end of the heat preservation shed. The nursery trays are fed into the seedling bed by the annular conveying belt, the nursery trays on the seedling bed are removed by theannular conveying belt, automatic operation of an ebb-and-flow irrigation system is realized, and production efficiency is improved. In addition, as manual operation is avoided, the building height of the heat preservation shed is greatly reduced, space use ratio is increased, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production equipment, and in particular relates to a low shed tidal irrigation seedling raising system. Background technique [0002] Tidal irrigation technology is a new type of seedling irrigation method that uses bottom water supply. It places the seedling tray in a large shallow tank container, and realizes the fluctuation of the liquid level through intermittent water supply in the container, so as to control the seedling tray. Hydrate intermittently. Compared with traditional sprinkler irrigation, tidal irrigation has the following advantages: 1. Fertilizer solution, growth regulator, and water are completely circulated in a closed system, and the reflux liquid is completely recycled, water-saving and efficient, and can reach 90% utilization without effluent , is a green and environmentally friendly planting technology; 2. Avoid the water film on the leaves of plants, so that the leave...

AI Technical Summary

Problems solved by technology

However, the existing tidal seedbeds are all fixed structures, and it is necessary to manually place the seedling trays on the seedbed one by one. After the seedlings are completed, the seedling trays need to be removed one by one and the seedbeds are cleaned, which is time-consuming and laborious on the one hand, and the work efficiency is low. On the other hand, due to the need for manual operation, the construction height of the insulation shed is relatively high, which not only reduces the space utilization rate but also increases the construction cost of the facility
