Problems solved by technology

[0004] However, as we all know, in the process of raising sweet potato seedlings, the whole sweet potato is buried in the soil, and this kind of seedling raising treatment will cause a waste of sweet potato resources, resulting in difficulties in the germination of the lower half. Use plant ash to sterilize the sectioned part, dry it, make it aged, and bury it in the soil with the section facing down to realize sweet potato seedling cultivation; also use sweet potato skin, and control the thickness of the sweet potato skin, so that the nutrition can be satisfied , in order to realize the treatment of sweet potato seedlings, but whether it is splitting or using sweet potato skins for seedling raising treatment, it needs to use sweet potatoes, resulting in higher seedling cost in the process of sweet potato planting

Abstract

The invention relates to the technical field of red core sweet potato seedling growing, in particular to a seedling growing method for utilizing red core sweet potatoes as seeds. By selecting the diameters of red core sweet potato vines, it is avoided that red core sweet potatoes are frozen off or moisture is totally evaporated in the storage process, it is ensured that the stored red core sweet potato vines can recover the activity in the next March, through the combination of selection, preparation and treatment of raw material components of a seedling growing matrix, nutrients can be comprehensively provided for rooting and seedling emergence of the red core sweet potato vines, it is also ensured that the red core sweet potato vines cannot be damaged in the cutting process, infection ofharmful florae is avoided, and the cutting survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of red-core sweet potato seedling cultivation, in particular to a method for raising seedlings of red-core sweet potato vines. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato; it contains starch, protein, fat, carbohydrates, crude fiber and other vitamins and trace elements; regular consumption of sweet potato has the effects of moisturizing the intestines, laxatives, and improving immunity. There are many types of sweet potatoes. According to the different colors of sweet potatoes, they are divided into purple sweet potatoes, red-core sweet potatoes, white-heart potatoes, etc.; while fresh food, red-core sweet potatoes are better, and their taste and sweetness are better than other types. Sweet potatoes are better. [0003] At present, for the cultivation of red sweet potatoes, in Ziyun County, Anshun City, Guizhou Province, the planting area is relatively...
