Embodiment 1

[0037] A kind of high-efficiency breeding method of virus-free small seed potatoes, comprising placing the virus-free seed potatoes in a sterilized dark cold storage, maintaining the conventional required oxygen content in the cold storage, and then accelerating germination in the cold storage, when the virus-free seed potatoes germinate Finally, control the temperature in the cold storage at 22°C during the day and 13°C at night to promote the growth of stolons and the formation and expansion of tubers, and spray the nutrient solution on the detoxified seed potatoes at intervals until they form and can be harvested. The effect of breeding small seed potatoes from virus-free seed potatoes is as follows: figure 1 shown.

[0038] Among them, ① the variety of the virus-free seed potato is: Feureta; the weight of each virus-free seed potato is greater than 76g, and the average weight of each virus-free seed potato is 81g;

[0039] ②The small seed potato that can be harvested is s...

Embodiment 2

[0047] A kind of high-efficiency breeding method of virus-free small seed potatoes, comprising placing the virus-free seed potatoes in a sterilized dark cold storage, maintaining the conventional required oxygen content in the cold storage, and then accelerating germination in the cold storage, when the virus-free seed potatoes germinate Finally, control the temperature in the cold storage to 16°C during the day and 10°C at night to promote the growth of stolons and the formation and expansion of tubers, and spray the nutrient solution on the detoxified seed potatoes at intervals until they form harvestable tubers. small seed potatoes.

[0048] Among them, ① the variety of the virus-free seed potato is: Gui Nongshu No. 1; the weight of each virus-free seed potato is more than 77g, and the average weight of each virus-free seed potato is 84g;

[0049] ②The small seed potato that can be harvested is small seed potato with a weight of 2g;

[0050] ③ Disinfection of the cold stor...

Embodiment 3

[0057] A kind of high-efficiency breeding method of virus-free small seed potatoes, comprising placing the virus-free seed potatoes in a sterilized dark cold storage, maintaining the conventional required oxygen content in the cold storage, and then accelerating germination in the cold storage, when the virus-free seed potatoes germinate Finally, control the temperature in the cold storage at 22°C during the day and 13°C at night to promote the growth of stolons and the formation and expansion of tubers, and spray the nutrient solution on the detoxified seed potatoes at intervals until they form and can be harvested. small seed potatoes.

[0058] Wherein options ① to ③, and ⑤ to ⑧ are all the same as in Example 1, and the only difference is that the mode of accelerating germination in the cold storage of option ④ is different from that of Example 1, and the mode of accelerating germination in the cold storage of Example 3 is: the temperature is maintained at 25°C , until the g...

Abstract

The invention discloses an efficient breeding method of small virus-free potato seed tubers. The method comprises the following steps: putting the virus-free potato seed tubers in a disinfected dark refrigeration house, then accelerating germination in the refrigeration house, after the virus-free potato seed tubers germinate, controlling the temperature in the refrigeration house at 16-22 DEG C in the daytime, controlling the temperature in the refrigeration house at 10-13 DEG C at night so as to promote the growth of stolons and the formation and expansion of tubers, and spraying a nutrient solution to the virus-free potato seed tubers at intervals until small potato seed tubers capable of being harvested are formed. The breeding coefficient reaches 120 times or above, the breeding method has the advantages of being environmentally friendly, low in cost, easy to operate and convenient to implement and takes effect quickly, products are free of toxicity and residues, and large-scale production of the small virus-free potato seed tubers is realized.

Description

technical field [0001] The invention relates to the technical field of potato seedling breeding, more specifically, the invention relates to a method and device for efficiently breeding virus-free potato seedlings. Background technique [0002] Potatoes are asexually propagated crops. In production, it is customary to cut large seed potatoes into pieces to increase the reproductive coefficient of seed potatoes, but the reproductive coefficient is still low (≤10 times), resulting in a large amount of seed potatoes (150kg / mu), High rate of rotten seeds, easy to be infected with various diseases, high cost of manual potato cutting (100-150 yuan / mu). In addition, due to the complicated operation and high cost of breeding seed potatoes, commercial potatoes are often used as virus-free seed potatoes and other series question. [0003] In response to the above problems, the existing patent (CN106561210 B) discloses the use of potato stem sections for rapid propagation of potato mi...
