Embodiment Construction

[0045] Sweet potato is a cross-pollination crop, self-fertile, and the offspring propagated by seeds have very inconsistent traits and low yield. Therefore, sexual reproduction is rarely used in production. Because the vegetative organs such as sweet potato roots and vines have strong regeneration ability and can maintain the traits of good varieties, asexual reproduction of roots, vines, and potato tips is often used in production.

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] According to the reproductive characteristics of sweet potatoes, the inventor has trial-produced a method for industrialized cultivation of virus-free red sweet potatoes. The specific steps are:

[0048] 1.1 Cultivation of virus-free test-tube plantlets

[0049] 1.1.1 Germination and heat treatment of potato pieces

[0050] Wash the potato pieces, disinfect them with 50% carbendazim 800 times solution for 20 minutes, then sele...

Abstract

The invention relates to a factory propagation method for detoxified red sweet potato. The method comprises the step of detoxifying test-tube plantlets, breeder seeds, stock seeds and improved variety. The method specifically comprises the following steps: firstly, cleaning potato blocks, using 800-times diluted solution of 50% carbendazim for disinfecting for 20min and then performing 26 DEG C constant temperature sprouting; adopting a high/low temperature alterative treating mode of treating for 16 hours at 26 DEG C and treating for 8 hours at 35-40 DEG C in each day for continuously treating for about 30 days when the buds grow to 0.1-0.5cm; performing stem apex detoxification, rapid tissue culture propagation, rooting and seedling hardening, rapid water culture propagation, potato vine transplanting and breeder seeds propagation; and using the breeder seeds for rowing potato and seedling in the greenhouse with a fly net in the next year; transplanting into field, performing field management, controlling pests, timely harvesting and storing the stock seeds before frosting and propagating the excellent stock seeds. According to the invention, the detoxified seedlings can be subjected to factory propagation within a short period of time, the production cost of the detoxified seedlings can be reduced and the lastly acquired detoxified improved variety is convenient for the peasant to plant, transport and store.

Description

technical field [0001] The invention belongs to the field of planting agricultural products, and in particular relates to a factory breeding method of virus-free red sweet potatoes. Background technique [0002] Red sweet potato is a local characteristic sweet potato variety. It is rich in nutrition, good in taste, excellent in variety, smooth in skin, slender and uniform in shape, and has a good market prospect. It is one of the main crops for agricultural industrial structure adjustment. In production, because farmers have long adopted the method of self-propagating cuttings of self-retained potato pieces, many years of asexual reproduction and planting have caused seed potatoes to be infected and accumulate viruses, causing serious species degradation, reduced yield and quality, and serious pests and diseases. Contents of the invention [0003] The purpose of the present invention is to provide a method for producing test-tube seedlings, original seeds and original seed...
