Problems solved by technology

[0003] Commonly used detoxification methods for sweet potatoes include heat treatment and stem tip culture detoxification methods, etc., wherein the heat treatment detoxification method is to use the difference between the tolerance of the virus and the sweet potato to high temperature, so that the growth rate of the plant exceeds the diffusion rate of the virus, and a small amount of virus is obtained. Some virus-free plant meristems are cultivated into plants from non-toxic individuals, but this method takes a long time to detoxify and is incomplete

Embodiment 1

[0022] A kind of sweet potato heat treatment detoxification method specifically comprises the following steps:

[0023] (1) Preferred sweet potato seedlings

[0024] Select 30-40 day-old sweet potato seedlings with good growth and excellent disease resistance for use. At this time, the stem tip cell division speed of sweet potato seedlings is the fastest, and it is easiest to obtain virus-free seedlings;

[0025] (2) Pretreatment of sweet potato seedlings

[0026] Use a 40W ultraviolet sterilizing lamp to irradiate the stem tips of sweet potato seedlings at a distance of 1.5 meters for 15 minutes, and then spray the liquid on the leaves around the shoot tips to increase the photosynthesis intensity of the leaves and the metabolism of the shoot tip cells, thereby accelerating the growth of the shoot tip tissue. growth, while effectively inhibiting the infection of the virus, the medicinal solution and its preparation method specifically include the following steps:

Abstract

The invention relates to a heat treatment detoxification method for sweet potatoes. The heat treatment detoxification method specifically comprises the following steps: (1) preferably selecting sweet potato seedlings; (2) pretreating the sweet potato seedlings; and (3) detoxifying the sweet potato seedlings. Proved by experiments, detoxified sweet potato seedlings obtained by using the heat treatment detoxification method for sweet potatoes, provided by the invention, are better in detoxification effect, and the yield per unit area reaches up to more than 2940kg, while the yield per unit area of the planted detoxified seedlings obtained by carrying out stem tip tissue culture on detoxified stem tips obtained by using the existing heat treatment detoxification method for sweet potatoes by using the same method is only 2258kg; and meanwhile, the method disclosed by the invention is shorter in time consumption and better in detoxification effect; and the existing heat treatment detoxification method often takes 2-4 weeks or even longer, while the method disclosed by the invention only takes about 10 days.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a heat treatment detoxification method for sweet potatoes. Background technique [0002] Sweet potato, sweet potato belongs to Tubular Flowers, an annual herb of Convolvulaceae, sweet potato is rich in protein, starch, pectin, cellulose, amino acid, vitamins and various minerals, and has the reputation of "longevity food". Traditional sweet potatoes are planted year after year, and the variety will degenerate, resulting in the production of sweet potatoes falling year after year, and the planting area is also declining. The main reason is that the sweet potato carries the virus due to the insect transmission of the virus, which inhibits the growth of the sweet potato and leads to a decrease in the yield of the sweet potato. Detoxification of sweet potato is to remove the virus in sweet potato and restore the nature of sweet potato growth. [0003] Common detox...
