Seedling culture method

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 method which includes the steps: laying a seedling bed which is an ebb-and-flow seedling bed and comprises a liquid storage tray and an annular conveying belt; building a heat preservation shed; feeding nursery trays, starting the annular conveying belt and placing the nursery trays on the annular conveying belt one by one until the liquid storage tray is filled with the nursery trays; performing irrigation until rice seedlings are formed; discharging the nursery trays, reversely starting the annular conveying belt, carrying the nursery trays conveyed to an outlet of the heat preservation shed to a placing rack one by one by an operator standing at the end of the heat preservation shed, and finishing seedling culture. The nursery trays are fed into the seedling bed by the annular conveying belt, the nursery trays on the seedling bed are removed by the annular 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 method. 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
