Description

Technical Field

[0001] The utility model belongs to the technical field of potato cultivation, and in particular relates to a potato seedling rapid propagation and cultivation device. Background Art

[0002] Potatoes are asexually propagated crops, and the viruses in their bodies can accumulate from generation to generation. In severe cases, the yield reduction can reach 40%-70%, seriously reducing the yield and quality of potatoes. Therefore, potatoes need to be "detoxified". After selecting seedlings with thick potato buds and cultivating them into several parts to the appropriate size, one plant is taken for virus testing. After the test is non-toxic, the seedlings cultivated from the same bud are rapidly propagated. During this process, the seedlings need to be provided with sufficient nutrition, suitable temperature and water. Utility Model Content

[0003] In response to the problems in the prior art, this solution provides a potato seedling rapid propagation and cultivation device, which can enable the selected potato seedlings to grow rapidly and stably in a cultivation box.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The potato seedling rapid propagation and cultivation device is characterized by comprising:

[0006] The incubator comprises an upper box body and a lower box body, wherein the lower box body comprises a bracket and a nutrient solution tank, and the nutrient solution tank is placed on the bracket; the upper box body comprises an insulated box, a seedling fixing plate and a lifting device, two connecting plates extending outward from both ends of the seedling fixing plate, the connecting plates and the lifting device are fixedly connected, and the side walls of the insulated box are provided with downward-opening limit grooves that cooperate with the connecting plates;

[0007] The nutrient solution replenishing device includes a liquid storage tank, a solenoid valve and a timing controller. The liquid storage tank is connected to the nutrient solution tank via an infusion tube. The solenoid valve and the timing controller are fixedly mounted on the infusion tube.

[0008] Constant temperature system, an electric heating tube is fixedly installed below the top surface of the upper box.

[0009] A timing controller is used to control the flow of a certain amount of nutrient solution into the nutrient solution tank at regular intervals, so that the nutrient solution is higher than the bottom of the seedling roots, but not all the roots are soaked, so that the potato seedlings can absorb enough water and nutrients and grow rapidly.

[0010] Preferably, the thermal insulation box includes a box body and a box door, and ventilation holes are provided on both side walls of the box door and the box body.

[0011] The vents facilitate air circulation inside and outside the incubator, allowing the plants to have enough oxygen to grow.

[0012] Preferably, a temperature detection probe is installed inside the side wall of the insulation box, the electric heating tube is connected to a temperature controller, the temperature detection probe is connected to the temperature controller signal, and the temperature controller controls the power on and off of the electric heating tube.

[0013] The temperature inside the incubator is instantly detected and heated using a temperature detection probe to maintain the temperature in the incubator within a constant range, which is suitable for the development and growth of potato seedlings.

[0014] Preferably, the lifting device is an electric push rod that is started synchronously.

[0015] The electric push rod can be started synchronously to push the seedling fixing plate up or down, which is convenient for adjusting the distance between the seedlings and the nutrient solution tank. Especially when the roots of the seedlings gradually develop, the distance between the seedlings and the nutrient solution tank needs to be increased to avoid the roots being squeezed and poorly developed.

[0016] Preferably, a drain pipe is installed at the bottom of the nutrient solution tank, and a valve is installed at the upper end of the drain pipe.

[0017] Preferably, the connecting plate is threadedly connected to the lifting device.

[0018] Preferably, the top surface of the heat preservation box is also connected to a ventilation pipe, the ventilation pipe is connected to a small fan, and the small fan is fixedly installed on the top surface of the heat preservation box.

[0019] The beneficial effects of the utility model are as follows: the nutrient solution tank is replenished with nutrient solution at regular intervals and in fixed quantities through a timing controller, thereby ensuring that potatoes have sufficient nutrient supply during growth and reducing the labor of staff; a lifting device is used to control the height of the seedling fixing plate, and the seedling fixing plate is moved up after the seedling roots grow, thereby avoiding dense distribution of the roots in the nutrient solution tank and promoting the development of the nutrient root system; and an electric heating tube is used to keep the temperature in the insulation box constant, which is suitable for the growth and development of the seedlings.
