Serial connection type soilless simple rice seedling growing tray for machine-transplanting hydroponically grown rice seedlings and rice seedling growing device

Abstract

The invention belongs to the field of rice seedling growing trays and discloses a serial connection type soilless simple rice seedling growing tray for machine-transplanting hydroponically grown riceseedlings. The tray comprises U-shaped rice seedling growing grooves, wherein a plurality of water storage holes are uniformly formed in the bottoms of the rice seedling growing grooves; wedged connectors and wedged connection holes are respectively arranged at both ends of the side walls of the rice seedling growing grooves; adjacent rice seedling growing trays are connected through the wedged connectors and the wedged connection holes; a first baffle plate is arranged at the end of the wedged connectors of the rice seedling growing tray; a second baffle plate is arranged at the end of the wedged connection holes; the first baffle plate is higher than the second baffle plate; the first baffle plate takes the shape of an ''L'' upside down; and when two adjacent rice seedling growing traysare serially connected, the plane of the top end of the first baffle plate covers the top end of the second baffle plate of an adjacent rice seedling growing tray. The rice seedling growing tray is small in floor space, nutrient soil (mediums) is discarded, the rice seedling growing cost investment can be reduced, moisture and nutrients can be maintained by the water storage holes, the fertilizerutilization efficiency can be improved, the water storage amount of the rice seedling growing tray can be increased through the baffle plates at both ends, a function of a space for root systems to bemutually tangled is also provided, and rice seedlings meet machine transplanting requirements.

Description

technical field [0001] The invention belongs to the field of rice seedling raising trays, and relates to a simple soilless seedling raising tray and a seedling raising device in series with machine-inserted water-rolled seedlings. Background technique [0002] At present, the rice production mechanization technology popularized and applied in my country mainly uses plastic trays or double films, and the pot seedling raising technology that has emerged in recent years to cultivate standard seedlings, and then transplants the seedlings to the field by riding rice transplanters. There are still some defects in the actual production and application of these technologies: 1. Regardless of the use of plastic trays or double-film seedlings, it is necessary to prepare a large amount of seedling soil from the field, plus fertilizer mixing, storage and other processes, which not only lead to high labor intensity , and lead to increased transportation costs and reduced efficiency.

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to solve the problems that the seedlings raised by the existing rice seedling raising equipment need to carry soil and matrix, which lead to high labor intensity of mechanical transplanting and transporting seedlings, frequent replacement of seedlings, and low efficiency. Soilless simple seedling tray, the seedling tray is light in weight, easy to store, use, and transport, short seedling raising cycle, and the price is reasonable
