Device and method for hydroponic production of virus-free potato seedlings

Abstract

The invention belongs to the technical field of potato seedling growth, and discloses a device and a method for hydroponic production of virus-free potato seedlings. The device is provided with a support frame; and a lower layer seedbed is welded to the inner side of the support frame, a plurality of crossbeams are welded to the upper end of the support frame, the upper end of the middle crossbeamis fixedly provided with a motor through bolts, the motor is connected with a power draw rod through a drive wheel, two ends of the power draw rod are connected with support rods through bearings, the upper end of the support frame is fixedly provided with pulleys through bolts, wire ropes are inserted to the outer sides of the pulleys, two ends of the wire ropes are welded to two sides of an upper seedbed, and the middles of the wire ropes are wound around the surface of the power draw rod. The hydroponic production device is provided with the upper seedbed and the lower seedbed, and the motor drives the power draw rod to drive the upper seedbed to move under the wire ropes in order to easily adjust the height of the upper seedbed according to production requirements, so the purposes ofimproving the space utilization rate and the production efficiency are realized without affecting production operations.

Description

Technical field [0001] The invention belongs to the technical field of potato seedling cultivation, in particular to a hydroponic production device and method for potato virus-free seedlings. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: [0003] There is no mature technical system for the hydroponic production of virus-free potato seedlings, and there is no uniform technical standard for related facilities and equipment. The currently used hydroponics facilities are mainly: hydroponic seedbed design specification length 1.2m*width 0.8*m*depth 0.06m, the height of the support from the ground is 0.7m, and each hydroponic seedbed can put 16 hydroponic trays (specification 19cm) *29cm), each hydroponic plate has 100 holes (aperture d=0.6cm), and each hydroponic seedbed is designed with a tap water injection switch and drainage hole. This kind of seedbed can effectively control the number of potato hydroponic seedlings ...

AI Technical Summary

Problems solved by technology

[0004] In summary, the problems in the prior art are: the existing potato hydroponic seedbeds have a low utilization rate of the greenhouse space, and the production efficiency is not high.

[0005] The difficulty and significance of solving the above technical problems: To improve the space utilization rate and production efficiency of the greenhouse, it can be solved by building a left-right mobile seedbed, but the potato adopts a liquid culture method to produce virus-free seedlings, and the seedbed is a liquid medium. After filling the liquid medium, the weight is very heavy, and moving left and right can easily cause the liquid medium to overflow, and it has high requirements on the power system. Therefore, the production of virus-free seedlings by potato hydroponics cannot be solved by moving the seedbed left and right to improve space utilization. rate and productivity issues
