Purple potato cultivation and planting method

Abstract

The invention discloses a purple potato cultivation and planting method, and belongs to the technical field of purple potato cultivation. The method includes the following steps of (1) pre-processing of seed potatoes, (2) seed arrangement and seedling of seed potato tubers, (3) management of purple potato seedlings, (4) cottage and cultivation of the purple potato seedlings, (5) field growth management of purple potatoes and (6) harvest of the purple potatoes. If the purple potatoes are planted through the method, it can be guaranteed that the seed potatoes can sprout and emerge as soon as possible, sprout dead corners on the surfaces of the purple potatoes in conventional cultivation can be eliminated, and the germination rate is improved by about 11.3%; meanwhile, by means of the seed arrangement mode of longitudinal cutting of the seed potatoes, a large number of the seed potatoes are saved, cost is lowered, longitudinal sections of the seed potato tubers are downward and cultivated so that it can be guaranteed that germination and emergence time of the ends of the seed potatoes and germination and emergence time of the longitudinal sections are consistent, and the emergence rate of the purple potatoes is improved by 9.4%; extra power equipment is not needed for heating and heat preservation, operation process is simple in step, equipment investment is low, and the survival rate and survival quality of the purple potato seedlings are improved; compared with a traditional method, the acre yield is improved by about 7%, and benefits of farmers are obviously improved.

Description

technical field [0001] The invention relates to a cultivation and planting method of purple potato, and belongs to the technical field of purple potato cultivation. Background technique [0002] Purple potato is rich in nutrients and has special health care functions. It is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. It is also rich in selenium and anthocyanins. It is digested and absorbed by the human body to meet the nutritional needs of the human body; the rich vitamins can improve human vision, etc., so the health care effect has attracted much attention. In addition, purple potatoes are delicious and can be eaten in various ways. They can be processed into whole powder, snack food, etc., the market The demand is large, so purple potato cultivation has high economic benefits. [0003] At present, before planting purple sweet potato, the following methods are mostly used to raise seedlings. One is to use large seedling sheds to...

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
