Abstract

The invention belongs to the technical field of vegetable cultivation, and particularly relates to a method of raising seedlings of sweet potatoes. The method comprises the following steps of (1) preparation of a culture substrate and a nutrient solution; (2) seedbed finishing; (3) seed sweet potato treatment; (4) seed arrangement; (5) temperature management; (6) water and fertilizer management. By preparing the culture substrate and the nutrient solution which are suitable for the growth of sweet potato seedlings, and combining specific seedbed finishing, seed sweet potato treatment and fieldmanagement methods, the method can obviously promote the growth of the sweet potato seedlings, increase the germination coefficient, accelerate the germination speed, and achieve uniform germinationto facilitate subsequent cultivation and management; at the same time, the incidence of common pests and diseases after seedling transplanting is significantly reduced, and a guarantee is provided forimproving the yield and quality of the sweet potatoes.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a method for raising sweet potato seedlings. Background technique [0002] Sweet potato is a yam variety widely cultivated in southern China. It is one of the important characteristic vegetable varieties and is widely loved by consumers. The underground roots of sweet potatoes are rich in carbohydrates, proteins, amino acids, cellulose and multivitamins, especially lysine, vitamin E and vitamin C, and are a healthy food. In addition, sweet potatoes can also be used as raw materials for the starch production industry, and the remaining potato residues after processing can also be used to prepare alcohol. The stems and leaves of sweet potatoes can also be used as livestock feed for comprehensive utilization, so the planting area of ​​sweet potatoes is also increasing. Count expansion. At present, there are unreasonable operating methods in the conventional ...
