Embodiment 1

[0016] A method for cultivating potato seedlings by sprouting, adopting the following steps: a. Place the original potato seed used for propagating first-grade seed potatoes on damp vermiculite in a darkroom to carry out shading and accelerating germination cultivation. The light in the darkroom is 1Lux and the temperature is 23°C , humidity is 80%; B, germination 30 days, when potato sprout grows to 45cm, take out potato with bud together, after bud is peeled off from potato cube, put back potato cube again in the original darkroom to continue germination cultivation; c, Use scissors to cut each bud node of the bud into small buds with only one growth point; d, soak the cut small buds in tap water at 10°C; e, transplant the soaked small buds in Cover the vermiculite in the single-layer film shed and cultivate it for 5 days. The light of the shed is 1200Lux, the temperature is 23°C, and the humidity is 75°C; Seedlings are ready for transplanting.

[0019] A method for cultivating and growing seedlings of potatoes, which adopts the following steps: a. Place the original potato seeds used for propagating first-grade seed potatoes on damp vermiculite in a darkroom to carry out shading and accelerating germination cultivation. The light in the darkroom is 25Lux and the temperature is 25°C , humidity is 90%; b, germination 35 days, when potato sprout grows to 53cm, take out potato with bud together, after bud is peeled off from potato cube, put back potato cube again in the original darkroom to continue germination cultivation; c, Use scissors to cut the small buds with only one growth point on the upper and lower sides of each bud node of the buds; d, soak the cut small buds in tap water at 25°C; e, transplant the soaked small buds in the Cover the vermiculite in the single-layer film shed and cultivate for 8 days, the light of the shed is 1800Lux, the temperature is 25°C, and the humidity is 85°C; f, remove the single-layer ...

Embodiment 3

[0022] A method for cultivating potato seedlings by sprouting, adopting the following steps: a. Place the original potato seed used for propagating the first-grade seed potato on damp vermiculite in a darkroom to carry out shading and accelerating germination cultivation. The light in the darkroom is 12Lux and the temperature is 24°C , humidity is 83%; b, germination 31 days, when potato sprout grows to 49cm, take out potato with bud together, after bud is peeled off from potato cube, put back potato cube again in the original darkroom to continue germination cultivation; c, Use scissors to cut the small buds with only one growth point on the upper and lower sides of each bud node of the buds; d, soak the cut small buds in tap water at 18°C; e, transplant the soaked small buds in the Cover the vermiculite in the single-layer film shed and cultivate it for 7 days. The light of the shed is 1560Lux, the temperature is 24°C, and the humidity is 79°C; Seedlings are ready for transp...

Abstract

The invention is particularly a potato seedling cultivation method through bud culture. The method solves the problems, namely complicated seed bud operation, difficult seedling cultivation shed building management and large seedling exercising difficulty, of an existing potato seedling cultivation method. The method includes the following steps that 1, potato seeds are placed in a dark room for culture, wherein the illumination of the dark room is less than or equal to 25 Lux, the temperature is 23-25 DEG C, and the humidity is 80-90%; 2, germination accelerating is conducted for 30-35 days, and stripping is conducted when buds grow to 45-53 cm; 3, the upper side and the lower side of each bud joint are cut to make buds into small buds; 4, the small buds are soaked, and the soaked small buds are subjected to cuttage in an arched shed for culture for 5-8 days, wherein the illumination of the arched shed is 1200 Lux to 1800 Lux, the temperature is 23-25 DEG C, and the humility is 75-85 DEG C; 5, a monolayer thin film on the arched shed is removed, and when the buds are continuously cultured to grow 5-6 leaves, seedling cultivation is completed. According to the method, in the potato seedling cultivation process, the survival rate is up to 855, and the production cost of potatoes is reduced.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture and planting, in particular to a potato bud culture and seedling raising method. Background technique [0002] Potatoes are the main vegetable crops in my country. In January 2015, the "2015 Planting Industry Work Key Points" formulated by the Ministry of Agriculture has listed potatoes as a key point. In the future, potatoes will gradually become the fourth largest staple food crop in my country. On the premise of not competing for water and land with the three major staple foods, the country will expand the potato from the current 80 million mu to 150 million mu by 2020, and increase the yield per mu from the current 1 ton to more than 2 tons. This is also the "stabilizing grain, increasing income, improving quality and efficiency" mentioned in the Central Document No. 1. [0003] The high price of virus-free potato seed makes the cost of potato production remain high. Current po...
