Problems solved by technology

However, the current domestic seed potato production system obviously has two main disadvantages: one is that potatoes are seeded with tubers, and the amount of seeds used is large, and seed potatoes need multi-stage breeding, which is slow and expensive.
The second is the phenomenon that the seed potatoes are infected by the virus again due to the limitation of environmental conditions or irregular operation and management in the multi-stage breeding process of the original seed, the first-grade seed potato and the second-grade seed potato by the farm or farmers. This kind of problem that seriously affects the quality of seed potatoes in our country occurs from time to time in various places

Embodiment Construction

[0057] The production method of potato virus-free seedling of the present invention:

[0058] (1) The insect-proof greenhouse and the required tools, utensils, seedling trays, and seedbeds are routinely disinfected.

[0059] (2) In the insect-proof warm net room, the operator changes clothes and washes his hands, cuts the test-tube seedling into a stem section with one leaf and inserts it in the holes of the plastic foam cutting board, the hole distance is 2cm×2cm. Put them into the rooting solution (1cm-1.5cm deep) in the culture bed for rooting culture. Under the condition that the temperature is 23° C. to 25° C. and the humidity is 80%, rooting is completed in 4 to 5 days. The formula of rooting liquid is:

[0060] NH 4 NO 3 825mg / L MnSO 4 4H 2 O 11.15mg / L

[0061] KNO 3 950mg / L ZnSO 4 ·7H 2 O 4.3mg / L

[0062] CaCl 2 2H 2 O 220mg / L Na 2 m 0 o 4 2H 2 O 0.125mg / L

[0063] MgSO 4 ·7H 2 O 185mg / L CoCl 2 ·6H 2 O 0.0125mg / L

Abstract

A liquid culture method and apparatus for fast reproduction of potato includes such steps as detoxicating the seed potato, quick reproducing the detoxicated seedling in test tube containing sugar-free culture liquid, and industrically reproducing the miniature potato in sugar-free culture liquid in open mode.

Description

technical field [0001] The invention relates to a propagation technology of potato seedlings and miniature tubers, in particular to an open-type liquid culture rapid propagation method and device for virus-free potato seedlings and miniature tubers. Background technique [0002] It has become the fundamental way to develop potato production all over the world by adopting virus-free technology and keeping seed potatoes healthy and virus-free to achieve high-quality and high-yield through tissue culture and rapid propagation. According to the introduction of "Potato Virus-free Seed Potato Production Technology" (Chinese Academy of Agricultural Sciences Western Agricultural Practical Technology Series, March 2001), my country's potato virus-free rapid propagation and seed potato propagation technology, including test-tube tuber and micro-tuber factory production technology, have great potential. world advanced level. Its production mode varies according to the geographical and ...
