Problems solved by technology

[0004] Sweet potato has been troubled by black spot during the planting process. For this reason, there are many institutions across the country that specialize in the study of sweet potato detoxification, but no ideal method has been found so far.
Black spot disease is usually infected during the process of raising seedlings with sub-potatoes, but it is difficult to achieve absolute detoxification. At the same time, the cost of medication is high, it is difficult to control, and the drugs are easily left in sweet potatoes
Sweet potato yields are also low due to the presence of black spot disease

Embodiment 1

[0044] A virus-free planting method of sweet potatoes, comprising the following planting steps:

[0045] S1. Sweet potato seedling cultivation

[0046] From August of the previous year to before winter, take strong sweet potato seedlings and plant them in the cultivation soil and cultivate them in a shed. After cultivating until the beginning of March in the second year, the side vines with good growth will be taken as sweet potato seedlings. The following raw materials are included in the following weight percentages: 5% shell powder, 1% selenium fertilizer, 4% organic fertilizer, 0.3% indole acetic acid, 1.5% humic acid, 1% magnesium sulfate, 2.5% iron sulfate, and the rest is red soil; The sweet potato seeds after the germination are planted in the shed of the seedling cultivation field, and the sweet potato seedlings are obtained after conventional planting for 30 days;

Abstract

The invention discloses a virus-free planting method of sweet potatoes. By means of seedling culture, soil preparation and ridging, seedling transplanting, field management and accurate control for aharvesting step in a sweet potato planting process, virus-free planting of the sweet potatoes is realized, and capacity of resisting black spot of the seedlings is improved. The survival rate of the sweet potato seedlings after transplanting is up to 95%, the seedlings grow rapidly, and meanwhile, yield of the sweet potatoes per mu is increased by 200-300 kg with the adoption of the virus-free planting method of the sweet potatoes. 100% virus-free effect can be realized with the planting method of the sweet potatoes, and the black spot of the sweet potatoes is prevented.

Description

technical field [0001] The invention relates to the technical field of sweet potato planting, in particular to a poison-free planting method of sweet potato. Background technique [0002] Sweet potato, also known as sweet potato, is rich in mucus protein, which can not only maintain the lubrication in the joint cavity, but also maintain the elasticity of the human cardiovascular wall, prevent atherosclerosis, reduce subcutaneous fat, and prevent liver and kidney damage. Connective tissue atrophy improves the body's immunity. Sweet potato unique dehydroepiandrosterone, can prevent colon cancer and breast cancer. [0003] Sweet potato is rich in nutrients, rich in starch, sugar, protein, vitamins, cellulose and various amino acids, it is a very good nutritional food. The starch content of sweet potato is high, and the starch content in the root tuber generally accounts for 15%-26% of the fresh weight, and the high content can reach 30%; the soluble sugar accounts for about 3...
