[0002] Seedling cultivation refers to the stage in which various plants are artificially cared for when they are young until they can survive independently. The process of seedling cultivation is a labor-intensive, delicate, time-consuming and highly technical job. When the seedlings grow healthily to a certain stage, they need to be transplanted into the land for planting. The most widely used method is to use cultivation cups or seedling bags to cultivate seedlings. Before cultivation, it is necessary to build a seedling bed in the shed area, and then place the cultivation cups or seedling bags filled with seedling nutrient soil in the seedling bed in turn, and finally sow the soaked tree seeds in the seedling soil in the cultivation cups or seedling bags. At this time, the sowing operation before seedling cultivation is completed, and the tree seeds absorb water, germinate and grow into seedlings. The roots of the seedlings absorb sufficient water and nutrients and grow into seedlings. After being aired, the seedlings gradually adapt to the natural environment and then grow into load-bearing seedlings.
