Abstract
The present invention discloses a biological selenium-enriched rice breeding method. The method is characterized by comprising the following steps: (1) leveling fields; (2) performing observation and recording; (3) performing pest control, and fertilization; (4) applying selenium; (5) carrying out additional irrigation; and (6) carrying out harvesting. Compared with the prior art, the biological selenium-enriched rice breeding method disclosed by the present invention has advantages that: according to the breeding method disclosed by the present invention, selenium absorption can be promoted during rice growth; human immunity can be improved; disease occurrence can be reduced; and the human resistance to diseases can be enhanced; and moreover, the disease resistance rate in a rice growth phase is enhanced, and the yield is improved; specifically, an average acre yield of rice is improved by 100-200 kg compared with that of rice cultured without using selenium.
Description
Technical field
The present invention relates to the breeding method of rice, particularly relate to a kind of biological selenium-enriched rice breeding method.
Background technology
China is a Ge Que selenium big country, and the soil of 72% all lacks selenium, has 1,000,000,000 crowds to need to mend selenium.But world's selenium is all also in China---enshi.Selenium in the earth's crust, only 1/1st, some places have, and some places are without, skewness.And content is also very low rare.In the long lived elder and Changshou village of China, quite part is all that geology is containing selenium residing for them, so plant is certainly just containing selenium, but selenium content is relatively low.Moreover the area that scarce selenium is serious, various strange illness, illness outbreak rate increase, and seriously endanger the general level of the health of people.Add social environment, air pollution, the residue of pesticide of agricultural product, hormone residues bring extreme influence to the quality of life of people.At present, national each State Scientific and Technological Commission payes attention to, and supplement selenium engineering will develop as enriching the iodine, widelys popularize rich selenium product and high selenium product, and selenium-rich rice selenium content on market is very low shallow.
Summary of the invention
The present invention is to solve above-mentioned deficiency, provides a kind of biological selenium-enriched rice breeding method.
Above-mentioned purpose of the present invention is realized by following technical scheme: a kind of biological selenium-enriched rice breeding method, is characterized in that: comprise the following steps:
(1) flatten field: before sowing, will prepare the field leveling executing selenium, gradient ensures to be less than 20 degree, otherwise will affect the evening ratio of selenium in field;
(2) observed and recorded: before executing selenium, observe seedling growth situation at any time, perform record, the waterline in field is no more than 7cm;
(3) pest control, fertilising: carry out rice pest control and fertilising before executing selenium, water level keeps 3 ~ 4cm degree of depth;
(4) execute selenium: within first 15 days, execute selenium at Rice Heading, with the former powder of selenium of every cubic metre of use 10 weight portion, then be added to the water, pour into field with water, and ensure that water does not leak, run off;
(5) controlling water level: before grain maturation, if during the degree of depth of the water of Tanaka less than 3 ~ 4cm, need to add filling, when temperature reaches 35 DEG C, need slightly increase water level 2cm;
(6) gather in the crops: during maturation that the grains are plump, the few water in field or anhydrous the best, make paddy full grains, selenium content is high.
The present invention's advantage is compared with prior art: adopt breeding method of the present invention that paddy can be allowed to grow and absorb selenium, body immunity can be made to improve, reduce disease and occur, strengthen the disease-resistant physique of human body; Strengthen the disease-resistant rate in paddy vegetative period simultaneously, improve output, 100 ~ 200 kilogram paddy higher than the paddy rice average yield per mu of not cultivating selenium.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
A kind of biological selenium-enriched rice breeding method, is characterized in that: comprise the following steps:
(1) flatten field: before sowing, will prepare the field leveling executing selenium, gradient ensures to be less than 20 degree, otherwise will affect the evening ratio of selenium in field;
(2) observed and recorded: before executing selenium, observe seedling growth situation at any time, perform record, the waterline in field is no more than 7cm;
(3) pest control, fertilising: carry out rice pest control and fertilising before executing selenium, water level keeps 3 ~ 4cm degree of depth;
(4) execute selenium: within first 15 days, execute selenium at Rice Heading, with the former powder of selenium of every cubic metre of use 10 weight portion, then be added to the water, pour into field with water, and ensure that water does not leak, run off;
(5) controlling water level: before grain maturation, if during the degree of depth of the water of Tanaka less than 3 ~ 4cm, need to add filling, when temperature reaches 35 DEG C, need slightly increase water level 2cm;
(6) gather in the crops: during maturation that the grains are plump, the few water in field or anhydrous the best, make paddy full grains, selenium content is high.
After step (4) selenium is executed, controlling water level gathered in the crops the best after 70 days, and the selenium-rich rice quality of results is good like this, mouthfeel is fragrant.
The selenium-rich rice 150 grams that feed adopts the inventive method to cultivate, just can supplement 378 microgram selenium elements.
Adopt method of the present invention long-term (more than 3 years or 3 years) to execute selenium in field, soil block, its soil can keep 5 years containing selenium composition, be one to stride forward greatly to agricultural science and technology.
The inventive method cultivate after rice straw, rice husk have higher value, rice straw chops up processing and can to feed animals after drying, do ox, horse herd material containing selenium, animals Long-term Feeding this type of herd material, its human body, just containing selenium, becomes rich selenium meat.Rice husk is by after retrofit, and can feed pig, sheep, domestic birds and animals, they feeding for a long time be also the rich selenium human body, and raw egg is also selenium rich of egg.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
Claims (2)
