Problems solved by technology

[0004] Simple low-temperature storage can prevent test-tube tubers from rotting for a certain period of time, but because dormancy regulation is not considered, test-tube tubers produced long before the planting season can pass dormancy naturally, but produced at a time close to the planting season Test-tube potatoes cannot pass dormancy naturally, and breaking dormancy chemically not only has a great impact on subsequent physiology, but also can easily cause disordered planting if not handled properly

Embodiment 1

[0036] a. Wash the test tube tubers with a dormant period of 45-60 days after harvesting, then ventilate and dry them for 1-2 days at 18-20°C to age the skin;

[0037] b. Shelves are installed in the storage according to the storage capacity, and hooks are set on the top of each layer. The test tubes are placed in plastic mesh bags and stored in the storage at 5±1°C. Take 3 tubers from the storage at 5±1°C every week. Store in the bag at 20±1°C;

[0038] c. During the storage period, keep the storage humidity at 70% ± 2%, and set up a T5 fluorescent lamp for every 0.8-1.2 square meters of the storage;

[0039] d. According to the germination rate reaching 80%, the storage time of different 5±1°C storages and 20±1°C storages is counted, and the obtained data is analyzed, and the mathematical model formula is obtained: y=-0.0005x2-0.3692x+ 75.488, R 2 =0.9869, wherein, x is the storage days at 5±1°C; y is the storage days at 20±1°C. Substitute the storage days at different te...

Embodiment 2

[0051] a. Wash the test tube tubers with a dormant period of 60-90 days after harvesting, then ventilate and dry them for 1-2 days at 18-20°C to age the skin;

[0052] b. Shelves are installed in the storage according to the storage capacity, and hooks are set on the top of each layer. The test tubes are placed in plastic mesh bags and stored in the storage at 5±1°C. Take 3 tubers from the storage at 5±1°C every week. Store in the bag at 20±1°C;

[0053] c. During the storage period, keep the storage humidity at 70% ± 2%, and set up a T5 fluorescent lamp for every 0.8-1.2 square meters of the storage;

[0054] d. According to the germination rate reaching 80%, the storage time of different 5±1°C storages and 20±1°C storages is counted, and the obtained data is analyzed, and the mathematical model formula is obtained: y=0.0008x2-0.5343x+104.87 , R 2 =0.9656, where, x is the storage days at 5±1°C; y is the storage days at 20±1°C. Substitute the storage days at different tempe...

Abstract

The invention relates to the field of potato microtuber storage, in particular to a storage method for potato microtubers, which includes the following steps: a needed day number of storage is calculated; a day number of altering-temperature storage is chosen, altering-temperature storage means y days of storage under 20 plus or minus 1 DEG C after x days of storage under 5 plus or minus 1 DEG C, and if the dormant period of the potato microtubers is 40 to 60 days, the formula is y equal to negative 0.0005x<2> minus 0.3692x plus 75.488; if the dormant period of the potato microtubers is 60 to 90 days, the formula is y equal to 0.0008x<2> minus 0.5343x plus 104.87; the sum of x, y and Delta P is the needed day number of storage, Delta P is an error day number, and the numerical range of Delta P is integers between negative 3 and 3. By calculating a mathematic model, the storage method can obtain storage times under different temperatures, and thereby determines a storage scheme, consequently, the stored potato microtubers can naturally pass dormancy, and the influence on the subsequent growth of seed potatoes as the result of a chemical method adopted to break dormancy is prevented.

Description

technical field [0001] The invention relates to the field of storage of test-tube potatoes, in particular to a storage method of test-tube potatoes. Background technique [0002] Test-tube tubers are tiny tubers produced under sterile conditions by using tissue culture technology and using virus-free test-tube seedlings, generally less than 1g. Test-tube potatoes not only do not carry viruses, but also do not carry any pathogens. They are the highest level of virus-free seed potatoes. Potato microtubers are seed potatoes (seedlings) made of test tube tubers (seedlings), which are produced at high density in an isolated greenhouse. The general size is 3-10 grams, which is defined as the original seed in production. At present, test-tube tubers are generally used as seed potatoes for miniature tubers, and test-tube tubers can be produced in laboratories every year. However, miniature tubers only have one season a year in the north, and two crops a year in the south. How to m...
