Embodiment 1

[0013] a. After the potato tube seedlings are transplanted into a temperature-humidity-controllable greenhouse, after 22 days of cultivation, the seedlings can be cut and cut when they have grown 7 leaves.

[0014] b. When cutting, keep 1 leaf on the aboveground part, and remove the leaf from the part inserted into the substrate. The depth of insertion accounts for 1 / 2 of the length of the cut section;

[0015] c. When cutting, the seedbed should be prepared in advance, and 8cm of forest soil should be laid in the seedbed as the cutting substrate. Before cutting, it should be watered thoroughly, and the tools used should be routinely disinfected;

[0016] d. During the cutting process, immediately place a small white film shed on the cuttage to keep it moist, and spray water once after the cuttage of a plot is completed, and put the whole shed to keep it moist. The humidity in the shed is 100%, and the temperature is 28°C. After 7 days, the seedlings grow out When new leaves o...

Embodiment 2

[0018] a. After the potato tube seedlings are transplanted into the net room, the cuttings can be cut when the seedlings have grown 8 leaves after 27 days of cultivation.

[0019] b. When cutting, keep 2 leaves on the aboveground part, and remove the leaves from the part inserted into the substrate. The depth of insertion accounts for 1 / 2 of the length of the cut section;

[0020] c. When cutting, the seedbed should be prepared in advance, and 10cm of peat soil should be laid in the seedbed as the cutting substrate. Before cutting, it should be watered thoroughly, and the tools used should be routinely disinfected;

[0021] d. During the cutting process, a part of the cuttings should be immediately covered with a small white film shed to keep it moist. After the cuttage of a plot is completed, water should be sprayed once, and the whole shed should be covered to keep it moisturized. The humidity in the shed is 100%, and the temperature is 25°C. After 8 days, the seedlings will ...

Abstract

The invention relates to a secondary shearing method for de-viruses potato germchit which comprises transplanting the test tube seedling, employing the breeding techniques of shearing, cutting and enlarging toxic seeds sprout to the fitness sprouts. The disclosed method can diminish the complex procedure of indoor test tube sprout breeding, it is time- and labor-conserving.

Description

technical field [0001] The invention relates to a secondary shearing method for virus-free potato seedlings. Background technique [0002] Potato is one of the important cultivated crops among non-cereal crops. It has the characteristics of high yield, early maturation, multiple uses, wide distribution, low cultivation seasonal requirements, and both vegetable and grain. It is one of the favorite vegetables in people's daily life. [0003] However, due to the harm of potato virus disease, the yield and quality of potato are seriously affected. A large number of experimental studies have proved that viruses are the main cause of degeneration. In order to solve the problem of potato degeneration, plant biotechnology—potato stem tip virus-free tissue culture technology is mainly used at present to obtain potato disease-free seedlings for planting, which can increase yield by 30% to more than double. [0004] To plant virus-free potatoes, it is first necessar...
