Abstract

The invention relates to a liquid cultivation device for virus-free potato seedlings. The potato virus-free seedling liquid culture device comprises a nutrient pool, a seedbed and a culture bottle located at the nutrient pool, the nutrient pool includes a pool body, and the pool body includes a liquid inlet, a liquid outlet and a control valve, and the nutrient The liquid can flow through the liquid inlet and the liquid discharge port. The seedbed includes a bed body and a lifting adjustment device. The bed body includes a planting panel and a plurality of planting holes passing through the planting panel. The culture bottle is set in the planting hole . The present invention also relates to a liquid culture rapid propagation method for cultivating virus-free potato seedlings using the liquid culture device for virus-free potato seedlings. This technology combines static liquid culture and intermittent liquid culture to make the cultivation of test-tube seedlings more efficient. The advantages of high efficiency and low cost. In addition, the growth cycle of potato plantlets in test tubes is shortened, and indicators such as stem diameter, plant height, leaf area, and dry weight have been significantly improved.

Description

technical field [0001] The invention relates to potato propagation technology, belongs to the field of agricultural planting technology, and in particular relates to a liquid culture device for virus-free potato seedlings and a liquid culture rapid propagation method thereof. Background technique [0002] At present, the cultivation of virus-free potato seedlings mainly includes the form of solid, semi-solid or liquid medium. The commonly used solid and semi-solid cultivation of tissue culture seedlings has the disadvantages of labor-intensive, high cost, and low degree of automation. Since the mid-1980s, western countries have tried to adopt the form of liquid medium to carry out liquid culture of virus-free potato seedlings. At present, potato liquid culture is generally carried out by static liquid medium, which has the advantages of adapting to large-scale production, reducing costs and reducing labor costs. However, due to the static type of the liquid medium, it is di...
