Description

Technical Field

[0001] The utility model relates to the technical field of agricultural seedling cultivation, in particular to a seedling cultivation device for agricultural promotion. Background Art

[0002] Seedling cultivation refers to the process of transplanting and planting seedlings after they have been cultivated in a nursery, hotbed or greenhouse until they can adapt to the external environment. Seedling cultivation can change the early environment of crop cultivation, shorten the growth period of crops in the planting field, improve the quality of seedlings, enhance the ability of crops to resist adverse growth environments, and thus increase crop yields. In the prior art, seedling cultivation usually involves planting seedlings in seedling trays, and then arranging the seedling trays neatly in a greenhouse for cultivation. When watering is required, sprinkler pipes are usually arranged in the greenhouse, and then water is pumped from a water source through a pump. When the water passes through the sprinkler pipes, it is sprayed from the sprinkler holes to water the seedlings. However, when using existing sprinkler pipes for watering, the amount of water sprayed by the sprinkler pipes is fixed. Due to the different types of seedlings planted in the seedling trays, the growth cycles of the seedlings are also different. When used, the amount of watering cannot be adjusted according to actual needs, which can easily cause too much or too little watering of the seedlings, thereby affecting the normal growth of the seedlings.
