Problems solved by technology

[0005] The selenium content in the existing sweet potato is relatively low. In order to increase its selenium content, a large amount of selenium-enriched fertilizer is usually applied. Although the selenium content of sweet potato can be improved to a certain extent, most of the lost selenium will cause environmental pollution, and the external The application of source selenium is not well absorbed by the body
Seedling methods for cultivating sweet potato seedlings with strong selenium-enriching ability are rarely seen now.

Embodiment 1

[0027] A method for raising seedlings of sweet potato seedlings with strong selenium-enriching ability, comprising the steps of:

[0028] (1) Seed potato selection: choose sweet potatoes with a bright and smooth surface, no damage and disease, and a single mass of 180-190g as seed potatoes for standby;

[0029] (2) Seed potato treatment: Rinse the seed potato selected in step (1) with clean water, then soak it in a 700-fold dilution of Gymboree Genmiaozhuang for 4 minutes, take it out, and then place it at a temperature of 25 Under the condition of ℃, after germination treatment for 12 hours, it is ready for use;

[0030] (3) Seed potato sorting: Arrange the seed potatoes treated in step (2) obliquely in the seedling substrate at an amount of 58 kg per mu. The seedling substrate is made of the following substances by weight: 41 parts garden soil, 24 parts 1 part of humus soil, 16 parts of peat soil, 15 parts of farm manure, 5 parts of animal offal, 7 parts of traditional Chin...

Embodiment 2

[0044] A method for raising seedlings of sweet potato seedlings with strong selenium-enriching ability, comprising the steps of:

[0045](1) Seed potato selection: choose sweet potatoes with a bright and smooth surface, no damage and disease, and a single mass of 190-200g as seed potatoes for standby;

[0046] (2) Seed potato treatment: Rinse the seed potato selected in step (1) with clean water, then soak it in a 700-fold dilution of Gymboree Genmiaozhuang for 6 minutes, take it out, and then place it at a temperature of 26 Under the condition of ~ 27 ℃, the germination treatment is accelerated for 14 hours, and then it is ready for use;

[0047] (3) Sowing of seed potatoes: Arrange the seed potatoes treated in step (2) obliquely in the seedling substrate at an amount of 63 kg per mu. The seedling substrate is made of the following parts by weight: 44 parts garden soil, 27 parts 1 part of humus soil, 19 parts of peat soil, 18 parts of farm manure, 7 parts of animal offal, 10...

Abstract

The invention discloses a seedling cultivation method of sweet potato seedlings with high selenium enrichment capacity, and belongs to the field of planting. The seedling cultivation method specifically comprises the following steps: (1) selection of seed sweet potatoes; (2) treatment of the seed sweet potatoes; (3) sowing of the seed sweet potatoes; (4) management after sowing; and (5) seedling harvesting. According to the method, all the steps are reasonably cooperated, so that the cultivated sweet potato seedlings grow uniformly and greenly, and are high in disease resistance, high in transplanting survival rate and relatively high in selenium enrichment capacity; compared with the existing method, the seedling cultivation method has the advantage that the selenium content of sweet potatoes cultivated in the later stage is doubled or more, and the use value of a sweet potato product is increased; and meanwhile, the seedling cultivation method eliminates a conventional complicated seedling hardening procedure and does not need extra treatment of fertilization and pesticide spraying, so that the planting process is optimized and easy to popularize.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for raising sweet potato seedlings with strong selenium-enriching ability. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, etc., is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. It has the reputation of "longevity food". Therefore, the price of this humble food is steep. The increase is impressive. Sweet potato is an annual plant of Convolvulaceae, a trailing herb, more than 2 meters long, lying flat on the ground and slanting upwards, with underground tubers, spindle-shaped tubers, and khaki or purple-red outer skin. Sweet potatoes are rich in starch, vitamins, cellulose and other essential nutrients for the human body, as well as mineral elements such as magnesium, phosphorus, calcium, and linoleic acid. These substances can maintain the elasticity of blood vessels and ar...
