Purple sweet potato cultivating and planting method

Abstract

The invention discloses a purple sweet potato cultivating and planting method and belongs to the technical field of purple sweet potato cultivation. The method comprises the steps of 1, potato seed pretreatment; 2, potato seed tuber arrangement and seedling culture; 3, purple sweet potato seedling management; 4, purple sweet potato seedling cuttage and cultivation; 5, purple sweet potato field growth management; 6, purple sweet potato harvesting. By the adoption of the method, it can be guaranteed that potato seeds can germinate as soon as possible; germination dead corners on the surface of purple sweet potato during conventional cultivation can be eliminated, and germination rate is increased by about 11.3%; meanwhile, through length cutting seed arrangement, potato seeds can be saved greatly, and cost can be reduced; cultivation is conducted with the longitudinal section of a potato seed tuber facing downwards obliquely, so that it is guaranteed that the end and longitudinal section of potato seeds germinate at the same time, and the emergence rate of purple sweet potato is increased by about 9.4%; heat supply and heat insulation do not need to be achieved through external electric equipment, operation steps are simple, equipment investment is low, and the survival rate and survival quality of purple sweet potato seedlings are improved; acre yield is increased by about 7% compared with traditional methods, and the income of farmer households is increased remarkably.

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
