Description
Technical field
The invention belongs to rice processing technique field, and in particular to a kind of selenium-rich nutritional rice production method.
Background technology
Selenium element is found for 1817, is confirmed as by the World Health Organization " necessary to humans and animals vitality within 1973
Trace element ".There is 72% area in a countries and regions selenium deficiency or low selenium more than 40 in the world, China, and 2/3rds population occupies
Stay in low selenium or Selenium deficiency area.Selenium and human life vigor are closely bound up, and selenium deficiency can cause a variety of diseases of human body occurred frequently, such as heart and brain blood
More than the 40 kinds of disease such as pipe disease, hypertension, diabetes, Kaschin-Beck disease, Parkinson's disease, cancer.Therefore, world health organisation recommendations
Human body daily 200 microgram selenium of supplement can effective prevention of various diseases generation, Chinese Soclety of Nutrition recommends the daily selenium of our residents
Intake is 50-200 micrograms.Required selenium cannot generate in human body, can only be supplemented by food intake.
Come from all times, people mainly carry out selenium-supply by rice cultivation production rice, but Se content is very low in soil, does not reach
Health needs, all more loaded down with trivial details from technological process, technical operation to implementing through retrieving domestic and international rice selenium-supply patent,
Nursery stage in rice, before transplanting, tillering stage, boot stage, florescence, grouting just, mid-term, repeatedly spray selenium-supply to seed phase etc.
Foliar fertilizer, input manpower and materials are larger, but effect is not very good.
The content of the invention
The purpose of the present invention is for it is existing the problem of, there is provided a kind of selenium-rich nutritional rice production method.
The present invention is achieved by the following technical solutions：
A kind of selenium-rich nutritional rice production method, by imposing selenium fertilizer a in rice anthesis, selenium fertilizer is imposed in rice milking stage initial stage
b；The selenium fertilizer a doses are 2.5-3.5kg per acre, and the selenium fertilizer b doses are 10.5-12kg per acre；
The selenium fertilizer a is added sodium selenite and is made using boron fertilizer as carrier, and the boron fertilizer is 20 with sodium selenite mass ratio:
0.1-0.5；
The selenium fertilizer b is made of following component by weight：Urea 12-15, ammonium molybdate 1.2-1.8, Purification of Diatomite carbonaceous
Shale selenium ore 4.2-4.6, zeolite powder 3-8, sodium metasilicate 4-6.
Further, the boron fertilizer is made of following component by weight：Bentonite 15, boric acid 4.
Further, the Purification of Diatomite culm selenium ore preparation method is：
（1）Use mass fraction to soak 30min at a temperature of 72 DEG C for 0.6% citric acid solution in diatomite, then carried out
Filter, it is dry to constant weight, it is then added in resistance furnace and is calcined, calcining heat is 435 DEG C, calcination time 25min, Ran Housui
Stove is cooled to room temperature, and is ground, and crosses 800 mesh sieves；
（2）Culm selenium ore is crushed, 250 mesh sieves is crossed, culm selenium mineral dust is obtained, by culm selenium ore
Powder presses 35g：200mL ratios are admixed together with deionized water, are heated to 80 DEG C, with 1500r/min rotating speeds stirring 2 it is small when,
Then be ultrasonically treated 5min, then add the phosphoric acid of culm selenium ore quality 1.5%, continue stirring 3 it is small when, then
Filtered, obtain culm selenium ore filtered fluid；
（3）By step（1）The diatomite and step of middle preparation（2）The culm selenium mineral dust suspension of middle preparation is pressed
120g：The ratio uniform of 350mL is admixed together, be then added in vacuum reaction kettle carry out vacuum impregnation 2 it is small when, Ran Houzai
Filtered, drying to constant weight, up to Purification of Diatomite culm selenium ore.
Further, the step（1）In diatomaceous density 2.0g/cm3, 52 ㎡ of specific surface area/g, pore volume 0.68m
³/g。
Further, the step（2）Middle ultrasonic power is 900W, frequency 40kHz.
Further, the step（3）Vacuum is 0.056MPa in middle vacuum reaction kettle, and soaking temperature is 70 DEG C.
Further, the zeolite powder granularity is 800 mesh.
The present invention has the following advantages compared with prior art：Pass through a kind of presently disclosed selenium-rich nutritional rice producer
Method, by carrying out imposing processing respectively using selenium fertilizer a and selenium fertilizer b in rice anthesis and Early filling stage, can be replenished in time water
The growth and development demand of rice, it is with strong points, absorption and utilization of the rice to selenium element and other nutrients can be effectively facilitated,
The content of selenium, carbohydrate and protein in raising rice so that rice has the nutritive value of higher, so as to effectively carry
High rice yield and quality, improves its mouthfeel, is added especially by florescence from Early filling stage using different materials containing selenium
It is added in selenium fertilizer, ability to bear and absorbability of the rice to trace elements of selenium can be gradually stepped up, so as to improve in rice
Se content, also improve the quality of rice and the yield of rice, promote absorption and accumulation micro- in rice, this hair
The rice selenium element content that bright method is cultivated is high, and the rice of method for producing selenium-rich rice production of the present invention is of fine quality, in good taste, volume increase
Amplitude is big, and average every per mu yield is up to more than 850 kilograms, and 150 mu of total outputs are up to more than 130 tons.
