Description

The implantation methods of selenium-rich black rice

Technical field

The present invention relates to a kind of planting technical field, and in particular to a kind of implantation methods of selenium-rich black rice.

Background technology

Black rice is a kind of medicine, the rice of food dual-purpose, belongs to glutinous rice class.Black rice appearance is pitch-dark, nutritious, has " black pearl " The good reputation of " king in world's rice ".The edibility of black rice is high, in addition to cooking congee, can also make various nutraceutical and wine Wine.Modern medicine also confirms that black rice has the curative effects such as enriching yin and nourishing kidney, strengthening spleen and warming liver, improving eyesight promoting blood circulation.

Selenium is a kind of chemical element, is also a kind of trace mineral nutrient needed by human, when selenium deficiency, just Human immunological competence's decline is easily lead to, human health and life is threatened, more than 40 kinds of disease of the mankind all has with human body selenium deficiency Close, such as cancer, cardiovascular disease, hepatopathy, cataract, pancreatic disease, diabetes, genital system diseases symptom.Due in human body In the absence of the organ of long-term storage selenium, the selenium needed for body can be obtained constantly from diet.In wholefood, selenium-rich is big Rice, Se-rich wheat, egg, garlic, seafood, mushroom, ginkgo etc. are all higher containing selenium element, and the crowd of selenium deficiency can suitably increase The food of this respect.Therefore, a kind of high-quality implantation methods of selenium-rich black rice are developed, be conducive to improving modern people's safety, nutrition, The diet state of health, with the wide market space.Carry out the distinctive selenium-rich rice class plantation of tool has to health Important realistic meaning.

The content of the invention

It is an object of the invention to provide a kind of implantation methods for improving selenium element content in paddy rice black rice.

In order to selenium element content is low in solving the problems, such as black rice, the present invention is adopted the technical scheme that：Selenium-rich of the invention The implantation methods of black rice, including seed selection treatment, nursery, rice transplanting, field management and results, specific method are as follows：

1）Seed selection is processed：Qualified black rice seed is selected, is basked seeds 3 ~ 4 days, then soak vernalization in 25 ~ 30 hours with 30 ~ 35 DEG C of warm water, The sodium selenite of its weight 1/10000 is finally added in seed, vernalization is continued after being sufficiently mixed, started after seed shows money or valuables one carries unintentionally Seeding and seedling raising；

2）Nursery：Selected around crop field one piece it is leeward on the sunny side, the convenient sand loam field of irrigation and drainage or nonirrigated farmland carry out film covering drought Seedling, appropriate light seeding, every mu of rice seedling bed broadcasts 4.5 ~ 6 kilograms, and every mu of crop field sowing quantity is 1.5 kilograms；

3）Rice transplanting：During black rice shoot transplanting equipment, with 9 ~ 10 centimetres of spacing in the rows, 18 ~ 25 centimetres of line-spacing is rationally planted, balled transplanting, every mu Participate Basic Seedling 25 ~ 300,000 in crop field；In site preparation before rice transplanting, well-rotted farmyard manure 500~800,000 are applied to every mu in soil Gram, it is 2-5 kilograms that sodium selenite amount is added in every kilogram of farm manure；

4）Field management：In the growth course of black rice, chemical pesticide and chemical fertilizer are not used；After field notes water conservation, ear period Especially note cutting off the water supply, cut off the water supply within first 5 ~ 10 days in black rice harvesting；

5）Harvest：To be gathered in early after black rice maturation, be gathered in when paddy is medium well, dried storage after independent threshing after harvesting and protect Deposit.

By adopting the above-described technical solution, the present invention is relative to the beneficial effect of prior art：

1st, implantation methods of the invention, are completed by seed selection treatment, nursery, rice transplanting, field management and results.The implantation methods pass through Optimize the breeding method of paddy rice, reasonable selection promotes preferably to absorb selenium element during seedling growth containing seleno fertilizer, is paddy rice Laid the first stone rich in selenium.

2nd, implantation methods of the present invention, it is comprehensive according to black rice paddy rice different growth phases to the different demands of nutritional ingredient Close configuration and contain selenium fertilizer, reasonable selection is carried out to fertilization time and the material that applies fertilizer, strengthen the growing way of black rice paddy rice different phase, enter And significantly improve selenium content and yield in black rice.

3rd, the quality of black rice that the present invention plants out is good, and mouthfeel is good, with special fragrance, and rich in selenium element, every 100 The energy of gram black rice, albumen, fat and carbohydrate and general rice are very nearly the same, and selenium, dietary fiber and lysine Content is higher by 5.67 μ g, 1.06mg, 42mg compared with general rice, respectively；Implantation methods of the present invention are scientific and reasonable, simple easily behaviour Make, environmental protection and public nuisance free, be adapted to large-scale promotion.

Specific embodiment

The present invention will be further described with reference to embodiments.

The implantation methods of this selenium-rich black rice, including seed selection treatment, nursery, rice transplanting, field management and results, specific side Method is as follows：

1）Seed selection is processed：Qualified black rice seed is selected, is basked seeds 3 days, then soak vernalization in 28 hours with 30 ~ 35 DEG C of warm water, finally The sodium selenite of its weight 1/10000 is added in seed, vernalization is continued after being sufficiently mixed, sowing is started after seed shows money or valuables one carries unintentionally Nursery；

2）Nursery：Selected around crop field one piece it is leeward on the sunny side, the convenient sand loam field of irrigation and drainage or nonirrigated farmland carry out film covering drought Seedling, appropriate light seeding, every mu of rice seedling bed broadcasts 5 kilograms, and every mu of crop field sowing quantity is 1.5 kilograms；

3）Rice transplanting：During black rice shoot transplanting equipment, with 10 centimetres of spacing in the rows, 20 centimetres of line-spacing is rationally planted, balled transplanting, every mu of crop field Participate Basic Seedling 280,000；In site preparation before rice transplanting, 600 kilograms of well-rotted farmyard manure is applied to every mu in soil, in every kilogram of agriculture It is 4 kilograms that sodium selenite amount is added in family's fertilizer；

4）Field management：In the growth course of black rice, chemical pesticide and chemical fertilizer are not used；After field notes water conservation, ear period Especially note cutting off the water supply, cut off the water supply within first 8 days in black rice harvesting；

5）Harvest：To be gathered in early after black rice maturation, be gathered in when paddy is medium well, dried storage after independent threshing after harvesting and protect Deposit.
