Problems solved by technology

This planting method is very suitable for all parts of the country, but due to the characteristics of sweet potato itself, such as high water content, high sugar content, high protein content, and certain toxic ingredients in the seedling stage of growth, these factors determine the short storage period of sweet potato, and starch Content, sugar content, protein and other ingredients are not very ideal

Embodiment Construction

[0005] 1. Virus-free seedlings: detoxify the young shoots at the seedling stage, and use the characteristics of low or no virus in the shoot apex of sweet potato to cut out 0.2-0.4mm shoot apex meristems under aseptic conditions. The test-tube seedlings are cultivated on the culture medium, and the virus-free seedlings without virus are detected by serology and grafting of indicator plants. At the same time, according to the variety, the corresponding tissue rapid propagation technical regulations and industrial production system are proposed to accelerate the propagation of a large number of multicolored flavor virus-free sweet potato seedlings, to ensure that the seedlings are non-toxic, then special cultivation is carried out, and then widely planted

[0006] 2. Planting management: According to the different utilization methods of the multicolored poison-free sweet potato, the corresponding high-yield and high-efficiency cultivation techniques should be studied according to...

Abstract

The invention relates to a method for culturing and planting seedlings of color virus-free sweet potatoes. The method is characterized by utilizing the characteristic of low virus content or no virus content in stem tips of the sweet potatoes, cutting meristems of the stem tips of 0.2-0.4mm under an aseptic manipulation, forming test tube seedlings by culturing on a specific culture medium, and further detecting the virus-free seedlings by serology and indicator plant grafting. Meanwhile, the invention further provides the corresponding tissue rapid propagation technical regulations and a factorized production system according to different types, thereby accelerating the propagation of a large number of color style virus-free sweet potato seedlings. The method can propagate the potato species which has high nutritional value and bright color and is applicable to fresh-eating, baking or processing of the preserved sweet potatoes.

Description

technical field [0001] The present invention designs a preferred seedling raising technique for crops, specifically discloses a seedling raising and planting method of multicolored poison-free sweet potatoes. Background technique [0002] Sweet potato has a great planting coverage rate in the vast rural areas of our country. For a long time in history, sweet potato has become the staple food of the masses of the people. It is also a good feed for raising livestock in rural areas of our country. Utilizing the deep processing of sweet potatoes, the purified starch, and the vermicelli, vermicelli, and vermicelli processed through different materials and various techniques have become a unique dish on the dining table in the vast rural areas and cities of our country. Even the extracted starch is widely used in cooking ingredients in major restaurants. As a crop with great nutritional value, sweet potato is planted all over my country because of its strong adaptability, and its...
