Cultivation and planting method for purple sweet potato

Abstract

The invention discloses a cultivation and planting method for purple sweet potatoes, belonging to the technical field of cultivation of the purple sweet potatoes. The cultivation and planting method comprises the following steps: (1) pretreatment of seed purple sweet potatoes; (2) arrangement of seed purple sweet potato tubers and seedling raising; (3) management of purple sweet potato seedlings; (4) cuttage cultivation of the purple sweet potato seedlings; (5) field growing management of the purple sweet potatoes; and (6) harvesting of the purple sweet potatoes. By using the method provided by the invention for planting of the purple sweet potatoes, germination and seedling emergence of the seed purple sweet potatoes as early as possible can be guaranteed; the germination dead area of the surface of the purple sweet potatoes in conventional cultivation can be eliminated, and the germination rate of the purple sweet potatoes can be increased by about 11.3%; meanwhile, longitudinal-cutting seed arrangement of the seed purple sweet potatoes can save a large number of seed purple sweet potatoes, so the cost is reduced; the seed purple sweet potato tubers are cultivated with the longitudinal cutting sections inclining down, so the time of germination and seedling emergence of the end part and the longitudinal cutting section of the seed purple sweet potato is guaranteed to be consistent, and the purple sweet potato seedling emergence rate is increased by about 9.4%; external power equipment is not needed for supplying heat and preserving temperature; the process is simple; equipment investment is low; the survival rate and the survival quality of the purple sweet potato seedlings are improved; and the yield per mu is increased by about 7% compared with the yield per mu in a traditional method, so benefits are significantly increased for farmers.

Description

technical field [0001] The invention relates to a purple sweet potato cultivation and planting method, 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, before the purple sweet potato is planted, the following metho...

Problems solved by technology

[0003] At present, before purple sweet potato is planted, the following methods are often used to raise seedlings. One is to cultivate in large seedling sheds, and to promote the growth and development of seedlings through external heating. The seedling raising steps are complicated, the process is cumbersome, and the equipment cost is high; , The purple potato is buried in the soil as a whole. This method of raising seedlings will lead to difficulty in germination of the lower part of the purple potato, poor emergence rate and quality of seedlings, low seedling raising efficiency, poor seedling survival rate and survival quality, resulting in seedlings after planting. The quality of the purple sweet potato produced is poor, which reduces the economic benefits of purple sweet potato planting
