Description

Technical Field

[0001] The present application belongs to the field of agricultural seedling cultivation, and more specifically, particularly relates to a cultivation device for cutting seedling cultivation. Background Art

[0002] Cutting seedlings, also known as cuttings, are a common method of propagation for growing plants. Existing cutting seedlings mostly use manual placement of branches into cutting seedling trays and uniform spraying. The spraying range is large and each seedling receives less water, and the sprayed water will also spill out of the planting area.

[0003] To solve this problem, a water-saving cutting nursery bed is provided in the prior art. Referring to the patent document with Chinese Patent Publication No. CN118235644A, the following technical scheme is specifically disclosed: the water-saving cutting nursery bed is provided with an outer frame which can move up and down inside the cultivation pot. When the cutting seedlings need to be transplanted, the outer frame is driven upward by an electric motor to move upward, and the culture soil inside the nursery bed is automatically divided without manual division. While the automatic division is uniform, the root system of a single cutting seedling is protected by the plastic pot inside the cultivation pot and will not be harmed, thereby improving the survival rate of the overall transplantation. A ceiling is provided above the nursery bed. When the cutting seedlings grow to a certain height and need to be transplanted, the ceiling is moved upward. When the ceiling moves, the outer frame is lifted upward to divide the culture soil. The ceiling can collect rainwater, and the irrigation water that is not absorbed by the cutting culture soil will be collected by the water collection frame.
