Abstract

The invention provides a method for protecting seedlings of sweet potatoes for vegetable use in a winter greenhouse and marketing sweet potato seedlings in advance. The method comprises the following steps of: 1) transplanting cut field matured seedlings into the greenhouse in the last ten days of October; 2) carrying out alive seedling period management on survived sweet potato seedlings in about 20 days after transplanting; 3) additionally covering the greenhouse with a vegetable shedding film in November and carrying out shed management on the sweet potato seedlings, and in the last ten days of March in the next year, picking the sweet potato seedlings in the greenhouse and marketing the sweet potato seedlings and reserving the sweet potato seedlings for field reproduction; and 4) in the middle ten days of April, transplanting the reserved seedlings in the greenhouse to the field, carrying out film covering management after transplanting, and picking and marketing the sweet potato seedling tips in the last ten days of May. The method provided by the invention can be used for effectively overcoming the phenomenon of seedling shortage caused by coldness and high humidity, the sweet potato seedlings can live through the winter and can be stored, and emerge quickly in the early spring to grab market share so as to obtain high benefit.
