Abstract
The invention discloses a method for cultivating selenium-enriched potatoes. The method comprises the following steps of selecting excellent potato varieties; blending sodium selenite in moist potatoes; covering the potatoes blended with the sodium selenite by using a plastic membrane so that the potatoes can sufficiently absorb the sodium selenite; and seeding after the potatoes absorb the sodium selenite. In the growing period, the resettling stage and the flower season of the potatoes, sodium selenite dilute liquid is uniformly sprayed on leaves of the potatoes, and the potatoes absorb the sodium selenite dilute liquid by using photosynthesis, so that the selenium content of the potatoes is increased. By using the method, the produced selenium-enriched potatoes are beneficial to human selenium absorption and health, and the selenium content of the potatoes cultivated by using the method is 4-8 times that of common potatoes.
Description
Technical field
The present invention relates to the cultivation method of a kind of potato, relate in particular to a kind of method with sodium selenite seed dressing spray culture Se-rich wheat.
Background technology
Potato selenium content height waits cultivation method to produce with sodium selenite seed dressing spraying.The current method with sodium selenite seed dressing cultivation of selenium-rich potato is to sow after mixing the wheat after humidity by sodium selenite substantially, at potato group's phase and florescence, with the first-class step composition of even its wheat seeding of the wet thin liquid spraying of sodium selenite.In cultivation for increasing the selenium content of potato, at the potato florescence, should Potassium, plant corpus being absorbed be converted into organic matter to increase Potassium Fertilizer.But when some rich selenium potato culture, just sodium selenite sprays or root uses containing selenium fertilizer, and the potato seed selenium content of producing does not reach the standard-required that needed by human body is wanted.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of potato selenium content and can reach people's somatogenic need standard, a kind of with sodium selenite mix moist after the method for Se-rich wheat of potato seed and the long-term spray culture of potato raw.
Technical scheme of the present invention is: the cultivation method of a kind of rich selenium potato, is characterized in that: the method includes following steps:
(1) by evenly moist the potato seed epidermis water of preparing vernalization after stripping and slicing, its part by weight is 100: 3-4;
(2) potato seed after humidity is mixed evenly to its weight ratio 100: 2-3 with sodium selenite;
(3) will mix uniform potato seed Mold for Plastics and cover tightly, potato seed is absorbed after its goods and materials, carrying out normal germination time is 10-12 hour;
(4) at a potato growth group phase and florescence, then with wet content after rare be 0.35-0.40% sodium selenite aqueous solution, spray respectively once.
Further, above-mentioned is 100: 3.5 by evenly moist potato seed epidermis water its weight ratio; It is above-mentioned that potato seed after humidity is mixed to evenly its weight ratio with sodium selenite is 100: 2.5; The above-mentioned uniform potato seed plastic foil of mixing covers tightly, and carries out normal vernalization after making potato seed absorb its goods and materials after 11 hours; Above-mentioned at a potato growth group phase and florescence, then with the sodium selenite aqueous solution wetting after rare, on the even wheat seeding of spraying, respectively once, the content of the sodium selenite of its sodium selenite aqueous solution is 3.756%.
Advantageous effect of the present invention is: perfect existing moist potato seed is dressed seed with sodium selenite, pack tightly its potato seed is fully absorbed with plastics membrane cover, in the time that potato seed germinates, just can make plant absorb and transform, and spray on its potato leaf with the wet thin liquid of sodium selenite in growth group's phase and florescence, make it pass through photosynthesis, inorganic matter is converted into organic matter.The potato selenium content planting with the present invention is 0.016-0.09mg/kg, it is 4-8 times that conventional method plants potato selenium content, meet the requirement of " selenium in food limit standard GB13105-91 ", its edibility and economic worth are greatly improved.
Use the present invention, by the method for the potato of sodium selenite seed dressing and spray culture, can make potato selenium content can reach the requirement of absorption of human body.The rich selenium potato of producing, human body is easy to absorb, and has edible safety, biological transformation ratio is high, and for improving the ubiquitous low selenium diet structure of people, prevent disease, improves body immunity, safeguards that people are healthy to have a great social effect.
