Efficient purple potato seedling method

Abstract

The invention discloses an efficient purple potato seedling method, and belongs to the technical field of purple potato cultivation. The method includes the following steps that (1) seed potato pre-processing is carried out and includes seed selection, soaking in medicine liquid, tuber cutting and pesticide spraying; (2) seed arrangement and seedling of seed potato tubers are carried out, wherein the seeds are planted, wetting is carried out through warm water, and mulch heat preservation is carried out; (3) purple potato seedlings are managed, wherein pesticides are sprayed, and the seedlings are cut. According to the seedling method, the surfaces of the planted purple potato tubers are soaked in the medicine liquid capable of promoting growth or the medicine liquid is applied to the surfaces of the planted purple potato tubers, and accordingly seed potatoes sprout and emerge as soon as possible; a seed arrangement mode that longitudinal sections are downward is adopted, so that the germination rate and the emergence rate of seed potatoes are improved, warm water is sprayed many times during seedling, and temperature and humidity of seedbed soil are effectively improved; in the seedling growth process, a proper quantity of fertilizers are applied for many times, a mulch film is used at the same time to achieve orderly temperature control, continuous and proper fertilizer support and proper temperature and humidity are provided for growth of the seedlings of the purple potatoes, the emergence rate and emergence quality are remarkably improved, the seedling steps are simple, electric equipment is not needed for heating and heat preservation, and investment 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 ...

Problems solved by technology

[0003] At present, purple potato seedlings are mainly raised through the following methods. One is to use large seedling sheds to promote the growth and development of seedlings through external heating. The 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 seedling emergence rate and quality, low seedling raising efficiency, poor seedling survival rate and survival quality, which is not conducive to the breeding and planting of purple potato.
