Sweet potato seedling cultivation device

Abstract

The invention discloses a sweet potato seedling cultivation device, and relates to the technical field of sweet potato planting equipment. The cultivation device includes a cultivation main body and aculture solution storage box which are installed on a pedestal; multiple liquid storage trays are arranged inside the cultivation main body, and seedling growing trays are elastically supported on the liquid storage trays; self-adjusting assemblies are arranged between the seedling growing trays and the liquid storage trays and include elastic members arranged on the two sides of the liquid storage trays; the upper ends of the elastic members are connected and installed on the seedling growing trays, and the lower ends of the elastic members are fixedly installed on the liquid storage trays;the two sides of the liquid storage trays are respectively provided with liquid discharging ports and liquid feeding ports, and a culture solution is quantitatively input to the liquid feeding ports;gate plates are arranged inside the liquid storage trays and attached to the opening ends of the liquid discharging ports, and the upper parts of the gate plates are lower than the upper edges of theliquid discharging ports; the gate plates are fixedly installed on the seedling growing trays through supporting rods; and the internal of the cultivation main body is arrayed with multiple heaters. Demands of the seedling growing trays on the culture solution can be well met, so that seedling growing rates can be increased; and the circulating flow supply of the culture solution can be realized so that the seedling growing rates can be increased.

Description

technical field [0001] The invention relates to the technical field of sweet potato planting equipment, in particular to a sweet potato seedling cultivation device. Background technique [0002] Sweet potato: Also known as sweet potato, it is a twining herbaceous vine of the genus Dioscorea in the family Dioscoreaceae. The top branch of the underground tuber is swollen into an ovoid tuber with light yellow outer skin and smooth. Stems left-handed, spiny at base, covered with T-shaped pilose. Sweet potatoes need to be nursed during the planting process. [0003] During the cultivation of sweet potato seedlings, the supply of culture medium directly affects the rate of seedling growth, and the existing culture medium supply process usually waits until the culture medium is reduced to the minimum before replenishing it, which cannot be dynamically It is supplemented, and then causes culture fluid to supply untimely, influences seedling raising rate, therefore needs to set up...
