Embodiment 1

[0019] The greenhouse cultivation method of the original original seed of potato detoxification comprises the following steps:

[0020] 1. Production of tissue culture seedlings

[0021] The production process of tissue culture seedlings is as follows: variety selection-virus-free treatment-virus detection-virus-free bottle seedling propagation-cultivation-transplanting

[0022] 1. Variety selection

[0023] Select or introduce virus-free bottle seedlings of excellent potato varieties suitable for local production: or carry out virus-free treatment on the main local excellent varieties.

[0024] 2. Detoxification treatment

[0025] Shoot apex meristem culture utilizes the inhomogeneous distribution of viruses in plant tissues, that is, the principle that the closer to the root and the top of the stem, the less virus there is, so as to achieve the purpose of eliminating viruses.

[0026] 2.1 Sowing and cutting buds

[0027] Choose healthy whole potatoes with obvious varieti...

Abstract

The invention discloses a greenhouse culture method for virus-free original-original potato seeds, pertaining to the technical field of cultivation of virus-free original-original potato seeds.The method comprises following steps of: 1) production of tissue culture seedlings, 2) processing of a seedling shed; 3) selection of seedlings and transplant, 4) greenhouse management, 5) timely harvest. The greenhouse culture method for virus-free original-original potato seeds has following beneficial effects: after turning soil, a base fertilizer and carbendazim are applied to a soil layer of 20cm in depth, then leveled and pressed, and aseptic bricks are utilized to set up culture areas mutually insulated to one another and disinfection treatment is performed; and compared with a conventional greenhouse culture method for virus-free original-original potato seeds, the greenhouse culture method for virus-free original-original potato seeds is low in cost, improved in quality and yield of original-original seeds and low in infection risk of culture seedlings.

Description

technical field [0001] The invention belongs to the technical field of potato virus-free original seed cultivation, and in particular relates to a method for cultivating potato virus-free original seed in a greenhouse. Background technique [0002] Potato has a long history of planting in my country, and it is the fourth largest cultivated crop after wheat, rice and corn, and has high nutritional value. In 2015, my country put forward the development strategy of "potato staple food", which shows that potatoes have huge potential for increasing production and broad development prospects. In recent years, due to the aggravation of environmental pollution, the probability of virus infection in potatoes has increased during planting. Potatoes are asexually propagated crops, and the viruses infected by them can accumulate from generation to generation, causing serious degradation of seed potatoes and seriously affecting the development of the potato industry. . With the deepeni...
