Abstract
The invention provides a selenium-enriched rice cultivating method. The method includes the following steps of seedling bed preparing, seed selecting and germination accelerating, rice seedling transplanting, field managing, topdressing and final harvesting. Rice planted through the method is high in yield and rich in selenium element, and it is detected through instruments that each kilogram of rice contains 0.3-0.5 milligram of selenium.
Description
Technical field
The present invention relates to agricultural plantation technology field, especially a kind of cultivation method of selenium-rich rice.
Background technology
Paddy rice is one of long staple food crop of China's cultivation history.Rice is of high nutritive value, good palatability, easily digests, and is not only the main food of China, also about has half population to take rice as staple food in the world.Paddy by product is of many uses, and its rice bran is the concentrated feed of domestic animal, and be also medical material, husk can be used as the raw material of industry, and straw is except can cooking feed stripped and Edible Fungi raw material and organic manure, or the raw material of paper industry etc.Therefore, development Rice Production, improves the quality of the output rice of paddy, is of great significance the development tool of Chinese national economy.
Selenium is a kind of nonmetalloid, is also one of trace element of needed by human body, is respectfully called the good reputation such as " kindling material of life ", " long-lived element ", " anticancer king ", " heart patron saint ", " natural antipoison " by domestic and international the world of medicine and nutrition educational circles.Selenium is 1/10000000th at tissue intensive amount, but it determines the existence of life, is that other materials are irreplaceable to the great function of human health.
Selenium-rich rice except the whole nutritions having retained common rice, also have anticancer, anti-cancer, cardioprotection and delay senility, anti-oxidant with elimination free radical, improve the multiple special health cares such as body immunity.Because the special health care of selenium-rich rice and the selenium mineral trace element that to be human body necessary, people are to the raising of quality of life in addition, so development in recent years is rapid.
Summary of the invention
For solving above-mentioned Problems existing, object of the present invention provides a kind of cultivation method of selenium-rich rice, and the selenium-rich rice output of the present invention's plantation is high, and selenium constituent content is high.
For achieving the above object, technical scheme of the present invention is:
A cultivation method for selenium-rich rice, comprises the following steps:
(1) select higher, the good field of soil structure of physical features, within before rice transplanting 15 ~ 30 days, deep plough to soil, topsoil depth is 25 ~ 35cm; Urea 50 ~ 60kg, wormcast fertilizer 150 ~ 180kg is executed, nanometer selenium plant nutrient agent 2 ~ 3kg at farmed soil surface every mu, and one deck balloonflower root that tiles up, balloonflower root layer thickness is 1 ~ 2cm;
(2) select pest-resistant sick ability strong, anti-fall, tiller strong, the percentage of earbearing tiller is high, fringe is large, the high-quality that ripening rate is high, the seed of high yielding variety, flat grain in screening removing rice paddy seed, damaged particle, seed is put after being exposed to the sun in the sun 1 ~ 2 day and put into container, earth is put in container, then the seed after drying under spreading in soil, a little water is sprayed at the surface of the seed with watering can, vessel surface plastic film covering is lived, every other day raise film watering can to spray water, under container need be placed in the temperature of 10 ~ 20 DEG C, the film be covered on container is removed after seed sprouting, afterwards 20 ~ 35 days, grow to after 7cm height can carry out rice transplanting until rice shoot,
(3) select fine day to carry out rice transplanting, the rice shoot degree of depth is 2 ~ 3cm, adopting 25cm line-spacing × 28cm cave apart from inserting rice shoot, executing farmyard manure 200 ~ 250kg, chemical fertilizer 140 ~ 160kg for every mu, and pouring water, be limited not have rice shoot auricle after rice transplanting;
(4) after rice transplanting, every two weeks is cut weeds once, and prevent damage by disease and insect, prevent and treat if desired, pour water in time with agricultural chemicals, guarantee can not be cut off the water supply or waterflooding;
(5) topdress in booting stage, execute urea 30 ~ 40kg for every mu, spray nanometer selenium plant nutrient agent to rice leaf; Full heading time executes every mu of urea 10 ~ 20kg again, continues to spray nanometer selenium plant nutrient agent to rice leaf;
(6) when spike of rice hangs down, golden yellow full time can gather in.
And described rice varieties is advisable fragrant 725 or excellent No. 6 or should any one in excellent 1988 of Q.
Meanwhile, the compound method of described nanometer selenium plant nutrient agent is: in 1L water, add potassium nitrate 1.11g, ammonium sulfate 0.18g, boric acid 0.05g, superphosphate 0.67g, magnesium sulfate 0.45g, nanometer selenium 0.01g, hold over night.
Beneficial effect of the present invention is:
The selenium-rich rice of the inventive method plantation, selects nanometer selenium plant nutrient agent, selenium element is more easily fully absorbed by plant, the paddy rice selenium content of planting out is high, every kilogram of paddy rice, containing selenium 0.3 ~ 0.5mg, improves the nutrient component of paddy rice, can obtain larger economic interests.
