Description

Technical Field

[0001] The invention relates to the technical field of rice cultivation, in particular to a rice cultivation seedling device. Background Art

[0002] Rice cultivation can increase people's food production and improve the growth of wetland organisms. Before rice cultivation, the rice seedlings need to be cultivated at a constant temperature through a seedling raising device, so that the rice seedlings can be maintained and cultivated by human intervention, which can improve the survival rate of the rice seedlings after being transplanted to the rice fields and further improve the rice yield effect. The seedling raising device can effectively help farmers achieve a stable cultivation effect on the rice seedlings. In summary, the inventors have found that the existing seedling raising devices mainly have the following defects: since most of the current seedling raising devices are usually set to single-layer seedling raising for the convenience of picking, the single-layer seedling raising will reduce the number of rice seedlings cultivated, thereby affecting the subsequent large-scale planting efficiency of rice fields, and the seedling raising area of ​​the current seedling raising device is formed by stable splicing. After the water source and nutrient soil are put into use, water molecules can easily flow out from the gap area of ​​the device through infiltration, which can easily lead to water shortage in the seedling raising area and pollute the dryness of the cultivation area.

The area of ​​the parallel body 34 is larger than that of the cultivator 35 and there are three groups of parallel bodies 34 in total. The control pull plate 31 can stably carry the three groups of parallel bodies 34 through its rectangular shape, and then improve the connection balance with the three groups of parallel bodies 34 to prevent tilting according to the flattened bonding layer 32 and the three rectangular grooves 33. The parallel bodies 34 can stably carry nutrients and water molecules through their own areas, and then allow the cultivators 35 to be embedded in parallel, so that the cultivators 35 can achieve the effect of easy disassembly and assembly on the parallel bodies 34 through a small area.

[0025] The cultivator 35 is provided with a vertical block 351, a hanging plate 352, a pull block 353, a carrier layer 354, and a limiter 355. The vertical block 351 is welded to both sides of the edge of the hanging plate 352. The upper edge of the hanging plate 352 is fixedly connected to the pull block 353.

At the same time, the roots of the rice seedlings can fully contact with the water molecules and nutrients after entering the water-retaining sponge a4, thereby improving the stability during cultivation and avoiding the mutual entanglement and contact between the roots of the rice seedlings during growth. By separating them one by one, subsequent transplanting can be facilitated. Example
