Description

technical field [0001] The invention relates to the technical field of irrigation for seedling cultivation, in particular to a sprinkler device for cultivating seedlings of new varieties of crops. Background technique [0002] Seedling cultivation means the cultivation of seedlings. The original intention refers to the cultivation of seedlings in nurseries, hotbeds or greenhouses, ready to be transplanted to the land for planting. It can also refer to the stage in which various organisms are artificially protected until they can survive independently. As the saying goes, "the seedlings are strong and half harvested". Seedling cultivation is a labor-intensive, time-consuming and highly technical work. In the cultivation of new crop varieties, the crops are cultivated in a large cultivation pool, and the seedlings are carefully cared for and easy to observe. [0003] What needs to be paid attention to in seedling cultivation is the watering process. The amount of water will...

Problems solved by technology

[0003] What needs to be paid attention to in seedling cultivation is the watering process. The amount of water will affect the health of the roots of the seedlings. Too little and uneven watering will affect the growth of the seedlings, which will easily cause water shortage. Too much watering will cause excessive humidity in the roots of the seedlings. Rotten roots, traditional artificial watering is difficult to control, if you don’t pay attention, you will sprinkle too much, and the watering will be uneven
