Problems solved by technology

Supplement selenium by eating inorganic selenium compounds, the absorption rate is low, there are certain side effects, and excessive intake can also lead to selenium poisoning
[0004] In recent years, functional agricultural products such as selenium vegetables and selenium-enriched food crops have been greatly favored. Reasonable and efficient development of selenium-enriched agricultural products is an important direction for future agricultural development. Selenium experiments show that an appropriate amount of selenium can increase crop yield and improve crop quality, but excessive selenium can inhibit plant growth, so the development of selenium-enriched agricultural products is difficult
[0005] At present, there are few reports on the cultivation of ashitaba, mainly focusing on increasing the content of its functional components, and there is no relevant report on the cultivation of selenium-enriched ashitaba

Embodiment 1

[0024] Embodiment 1, the cultivation method of selenium-enriched Ashitaba

[0025] 1) Soil preparation, every 1m 2 Apply 120g compound microbial fertilizer (wherein sodium selenite aqueous solution is used for every 1m 2 Add 7.5mg of selenium to the planting area and mix it with fertilizer), deep plowing and harrowing to level it out, and open a 12 cm deep ditch according to the row spacing of 12 cm;

[0026] 2) Select the 6-7 cm long root segment to prepare for planting, insert the root segment into the ditch according to the plant spacing of 9-12 cm, and cover the ditch with soil after watering. Routine field management is carried out during the growth period, and at the flower bud stage, the 2 Spray the amount of 7.5mg selenium on the leaves, spray the selenium-containing solution (the solution is prepared by dissolving sodium selenite in water) on the leaves, and harvest in autumn.

Embodiment 2

[0027] Embodiment 2, the cultivation method of selenium-enriched Ashitaba

[0028] 1) Soil preparation, every 1m 2 Apply 120g compound microbial fertilizer (wherein sodium selenite aqueous solution is used for every 1m 2 Add 41.5 mg of selenium to the planting area and mix it with fertilizer), deep plowing and harrowing to level it out, and open a 12 cm deep ditch according to the row spacing of 12 cm;

[0029] 2) Select 6-7 cm long seedlings to prepare for planting, insert the seedlings into the ditch at a plant spacing of 9-12 cm, and cover the ditch with soil after watering. Routine field management is carried out during the growth period, and at the flower bud stage, the 2 Spray the amount of 41.5mg selenium on the leaves, spray the selenium-containing solution (the solution is prepared by dissolving sodium selenite in water) on the leaves, and harvest in autumn.

Embodiment 3

[0030] Embodiment 3, the cultivation method of selenium-enriched Ashitaba

[0031] 1) Soil preparation, every 1m 2 Apply 120g of compound microbial fertilizer, deep plow and harrow to level; according to the row spacing of 12cm, open a 12cm deep ditch;

[0032] 2) Select Ashitaba cuttings with a length of 6 to 7 cm to prepare for planting, insert the cuttings into the ditch at a plant spacing of 9 to 12 cm, and water them at a rate of 1 m 2 Add 75 mg of selenium to the planting area, cover the selenium-containing soil (the selenium-containing soil is prepared by dissolving sodium selenite in water, and mixing it with soil), and level the ditch. Routine field management during the growth period, at the seedling stage at a rate of 1m 2 Spray the amount of 75mg selenium on the leaves, spray the selenium-containing solution (the solution is prepared by dissolving sodium selenite in water) on the leaves, and harvest in autumn.

Abstract

The invention discloses a cultivation method of selenium-enriched angelica keiskei. The cultivation method includes following steps: preparing land, fertilizing, ditching, planting angelica keiskei seedlings, watering, earthing, performing field management, and harvesting, wherein selenium is added at any stage of fertilizing, watering or earthing, and a selenium containing solution is sprayed onto leaves at an angelica keiskei stage or a flower bud stage during field management. Selenium-enriched angelica keiskei cultivated by the method can be directly eaten or prepared into deeply processedproducts like formula food or medicine by further adding other nutritional ingredients. The method is simple, easy-to-control in condition, stable in selenium content, needless of adding equipment and changing planting conditions and extremely wide in market prospect and is agricultural new technology having great economic prospect.

Description

technical field [0001] The invention specifically relates to a method for cultivating selenium-enriched Ashitaba and its application. Background technique [0002] Ashitaba (Angelica keiskei (Miq.) Koidz.) is a plant of the genus Angelica in the Umbelliferae family, a perennial herb; the plant height is 80-120 cm, the stems and leaves contain yellow sap, the stems are erect, and many branches. According to the shape of the plant, it can be divided into three varieties: green stem species, red stem species and mixed species. Ashitaba is a kind of vegetable with both medicine and food. It looks like celery. The tender stems and leaves can be eaten as vegetables. They can be fried, served cold, squeezed juice, fried, hot pot, boiled soup, stewed meat or made into tea juice. It has the effects of anti-cancer, preventing cell aging, and regulating chronic diseases. [0003] Selenium is one of the essential trace elements for the human body. It is of great significance to preven...
