A kind of purple sweet potato cultivation planting method

Abstract

The invention discloses a method for cultivating and planting purple sweet potatoes, which belongs to the technical field of purple sweet potatoes and comprises the following steps: (1) pretreatment of seed potatoes; (2) arranging seedlings of seed potatoes and tubers; (3) management of purple sweet potato seedlings; (4) ) Purple sweet potato seedling cutting cultivation; (5) Purple sweet potato field growth management; (6) Purple sweet potato harvest. Using the method of the present invention to plant purple sweet potatoes can ensure that seed potatoes can germinate and emerge as soon as possible; can eliminate the germination dead spots on the surface of purple sweet potatoes in conventional cultivation, and increase the germination rate by about 11.3%. Seed potatoes, reducing costs, planting the longitudinal section of the seed potato tuber obliquely downward, ensuring that the germination and emergence time of the end of the seed potato and the longitudinal section tends to be consistent, increasing the emergence rate of purple potato by about 9.4%; no need to use external power equipment for heating Heat preservation, simple operation process steps, low equipment investment, improve the survival rate and survival quality of purple sweet potato seedlings; the yield per mu is increased by about 7% compared with the traditional method, and the benefit of increasing the income of growers is obvious.

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
