Abstract
The present invention discloses a selenium-rich sweet potato growing method. The sweet potatoes are planted in conventional methods. The selenium-rich sweet potato growing method comprises a first step of carrying out seedling planting before May and spraying the seedlings with a selenium-rich diluent after survival of the seedlings from the planting; a second step of applying a selenium-rich fertilizer when cracks arise generally in the field, irrigating the selenium-rich fertilizer to roots of the seedlings along the cracks; a third step of spraying a mixed solution of sodium selenite and monopotassium phosphate onto stem leaves of the sweet potatoes in early August; and a fourth step of harvesting in time when the temperature drops to 15 DEG C. The selenium-rich sweet potato growing method has the advantages that the selenium-rich diluent, the selenium-rich fertilizer and the sodium selenite diluent are sprayed on the sweet potato seedlings in various methods at different phases, an absorptive amount of selenium to the sweet potatoes is raised, the selenium content of the sweet potatoes can reach 18-24 [mu]g/kg in selenium-deficient areas, the size of the sweet potatoes can also be raised, the acre yield of the sweet potatoes can be equal to or more than 4500 kg, the selenium-rich sweet potatoes can play a cancer prevention and beautification role after long-term consumption, and good quality and high yield of the sweet potatoes are realized.
Description
Technical field
The invention belongs to technical field of agricultural breeding, be specifically related to the implantation methods of a kind of rich selenium sweet potato.
Background technology
Starch containing 10-30% in sweet potato block root, the sugar of about 5% and a small amount of protein, grease, cellulose, hemicellulose, pectin, ash grade, its nutrient component in addition to fats, protein, carbohydrate equal size are all high than rice, flour, and albumen composition is more reasonable in sweet potato, necessary amino acid content is high, the lysine content in sweet potato particularly comparing shortage in Cereals based food is higher, in addition, the carotin enriched contained in sweet potato, vitamin A, B, C, E, and starch is also easy to be rapidly absorbed by a human.
Also containing enriching selenium in a lot of sweet potato, selenium makes the long-lived unique trace element of people.If can not get enough selenium, the cell in body then will suffer the torments such as virus, cancer, cardiopathy and early ageing.Selenium has antioxidation, is the scavenger of " free radical ", has antidotal effect.When people's interior antioxidation action difference can not remove again " free radical " in time, the speed of cell ageing also obviously shows quickening.Selenium and vitamin E play synergy, and vitamin E is incorporated on biomembrane, and Cell protection film, from the attack of free radical and peroxide injury, can make the appearance of lipofuscin postpone; People's interior free yl makes lipid peroxidation, infringement cell membrane, the unsaturated fatty acid on cell membrane is made to be cross-linked into lipofuscin, collagen in connective tissue is followed the string, and the peroxide of selenium by existing in the action breaks down body of glutathione peroxidase in cell, prevent the formation of harmful free radicals and the attack to unsaturated lipid thereof, this not only has effect to systemic cell, also effect is had equally to epidermal cell and hypodermis, can the aging death of delaying skin cell.Therefore, if containing a certain amount of selenium in sweet potato, act synergistically, can better be absorbed and used, play beyond thought effect with vitamin wherein, but at present because domestic a lot of area lacks selenium, the sweet potato selenium content of plantation is very few.
Summary of the invention
The object of the invention is for existing problem, provide the implantation methods of a kind of rich selenium sweet potato.
The present invention is achieved by the following technical solutions: the implantation methods of a kind of rich selenium sweet potato, comprises the following steps:
(1) before May by Seeding planting, after field planting survives, newly climing when growing to 5-10cm, spray with rich selenium dilution, continue to spray 1-3 days, diluent concentration is 30-50ppm, could the effective active ingredient absorbed in rich selenium dilution after seedling survives;
(2) when crack appears in field, use selenium-enriched fertilizer, be poured onto seedling root along crack, selenium-enriched fertilizer every mu amount of application is 150-200 kilogram, utilize the chance that there will be crack in nature planting process, to seedling root pouring fertilizer, its more effective absorption fertilizer nutrient can be made;
(3) at the beginning of 8 months, spray on sweet potato cauline leaf with the mixed solution of sodium selenite and potassium dihydrogen phosphate, now block root expanding stage just, mix with sodium dihydrogen phosphate, while sweet potato block root can be made to expand fast, increase its absorption to selenium;
(4) when temperature is down to 15 DEG C, gather in the crops in time, sweet potato can be caused to endure cold rotten, the resting period of sweet potato can be increased simultaneously.
As further improvement of these options, the solute of described rich selenium dilution is made up of the raw material of following weight portion: sodium selenite 30-40 part, diammonium phosphate 20-40 part, potassium dihydrogen phosphate 20-30 part, potassium sulfate 5-10 part.
As further improvement of these options, described selenium-enriched fertilizer is water soluble fertilizer, is made up of the raw material of following weight: sodium selenite 2-4kg, urea 4-6kg, potassium phosphate 3-6kg, superphosphate 6-8kg, in use with clear water dilution 200-400 times.
As further improvement of these options, the mu amount of application of described sodium selenite is 3-5kg, and the usage amount of potassium dihydrogen phosphate is 6-8kg, dilutes 500-800 doubly in use by after sodium selenite and potassium dihydrogen phosphate mixing with clear water.
Wherein, the selenium content of described rich selenium sweet potato is 18-24 μ g/kg.
The present invention has the following advantages compared to existing technology: by adopting rich selenium dilution to sweet potato respectively at different times, selenium-enriched fertilizer dilution, sodium selenite dilution sprays application to sweet potato seedling in many ways, makes sweet potato more can improve absorptive amount to selenium, in scarce selenium area plantation sweet potato, its Se content is made to reach 18-24 μ g/kg, increase the volume of sweet potato simultaneously, make sweet potato per mu yield reach more than 4500 kilograms, eat for a long time, the effect of anti-cancer, beauty treatment can be played, realize the good quality and high output of sweet potato.
