Abstract

The invention discloses an efficient seedling raising method for purple sweet potatoes, and belongs to the technical field of purple sweet potato cultivation. The method comprises the following steps of 1 seed potato pretreating, wherein seed selecting, soaking with pesticide liquid, tuber cutting and pesticide spraying are conducted; 2 seed potato tuber arranging and seedling raising, wherein planting, wetting with warm water and heat preserving with mulching film are conducted; 3 purple sweet potato seedling managing, wherein pesticide spraying and seedling cutting are conducted. According to the seedling raising method, all surfaces of seed potato tubers are soaked or smeared with the growth promoting pesticide liquid, therefore, seed potatoes can germinate as soon as possible, and seedlings can emerge as soon as possible; the mode of obliquely and downwards arranging seeds along the longitudinal section is adopted, therefore, the germination rate and the seedling emergence rate of the seed potatoes are increased, warm water is sprayed multiple times in the seedling raising process, and the temperature and the humidity of seedbed soil are effectively improved; in the seedling growth process, an appropriate amount of fertilizer is applied multiple times, sequential temperature control is achieved by combining the mulching film, continuous and optimal fertilizer support and suitable temperature and humidity are provided for the purple sweet potato seedlings, the seedling emergence rate is significantly increased, and the seedling emergence quality is significantly improved; the seedling raising steps are simple, no electrical equipment is needed for heating and heat preserving, and the invested cost is low.

Description

technical field [0001] The invention relates to a method for efficiently raising seedlings of purple sweet potatoes, which belongs to the technical field of purple sweet potato cultivation. Background technique [0002] Purple sweet potato is rich in nutrients and has special health functions. It is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. It is also rich in selenium and anthocyanins. The protein and amino acids are very easy to eat. It is digested and absorbed by the human body to meet the nutritional needs of the human body; rich in vitamins can improve human vision, etc., so the health care effect has attracted people's attention. In addition, purple sweet potatoes are delicious and have various eating methods. They can be processed into whole powder and snack foods. The demand is large, so the cultivation of purple sweet potato has high economic benefits. [0003] At present, purple sweet potato seedlings are mainly raised ...
