Description
Technical field
The present invention relates to selenium-rich nutritive agent prescription, in particular to a kind of Selenium-rich nutrient for producing selenium-enriched rice and its preparation
Methods and applications.
Background technology
Selenium is micro elements needed by human, and human body selenium deficiency can cause many diseases, for example：Kaschin-Beck disease, Keshan disease, hat
Worry etc.；" walking haltingly blind " syndrome and alkali disease occur during human body selenosis.Because the area of China 2/3rds belongs to scarce
Selenium area, soil Se content is not up to selenium-rich standard so that Se content is relatively low in agricultural product, is badly in need of improving agriculture using other method
The content of selenium in product.
At present, part, for the selenium-enriched fertilizer of production selenium-rich rice, using this kind of fertilizer, can cause rice in the market
Middle Se content increased, but be found according to investigation, and Se content otherness is larger in the selenium-rich rice produced using selenium-enriched fertilizer,
External environment is larger on the influence of the efficiency of rice absorbing selenium, and this kind of selenium-enriched fertilizer plant during preservation is available has
Imitate state selenium unstable, generally existing selenium element juvenescence, causing the validity of selenium in fertilizer reduces.
Therefore, being badly in need of a kind of stabilization of exploitation, efficient selenium-enriched fertilizer is used for the production development of high-quality selenium-rich rice.
The content of the invention
The present invention, which is directed to, uses the stability of selenium and Se content otherness in the selenium-rich rice of production in selenium-enriched fertilizer larger,
There is provided a kind of Selenium-rich nutrient for producing selenium-enriched rice and its preparation method and application.
To achieve the above object, a kind of Selenium-rich nutrient for producing selenium-enriched rice that the present invention is provided, the selenium-rich nutritive
The raw materials by weight portion of agent than meter include 0.5~1.5 part sodium selenite, 15 parts of chitosan, 35 parts of potassium dihydrogen phosphate,
55 parts of ammonium nitrate, 30 parts of glycine composition.
Further, the raw materials by weight portion of the Selenium-rich nutrient than meter include 1 part sodium selenite, 15 parts of shell
Glycan, 35 parts of potassium dihydrogen phosphate, 55 parts of ammonium nitrate, 20~40 parts of glycine composition.
Yet further, the raw materials by weight portion of the Selenium-rich nutrient than meter include 1 part sodium selenite, 15 parts
Chitosan, 35 parts of potassium dihydrogen phosphate, 55 parts of ammonium nitrate, 30 parts of glycine composition.
Yet further, the chitosan is water soluble chitosan.
Present invention also offers a kind of user for the Selenium-rich nutrient that selenium-enriched rice is produced described in claim 1 or 2 or 3
Method, comprises the following steps：
1) sodium selenite, potassium dihydrogen phosphate, ammonium nitrate, glycine, chitosan are weighed by above-mentioned ratio of weight and number；
2) sodium selenite and chitosan are added in 600~1000 parts of water, stirring and dissolving, is configured to solution at normal temperatures
A；
3) potassium dihydrogen phosphate, ammonium nitrate and glycine are added in 600~1000 parts of water, at normal temperatures stirring and dissolving,
It is configured to solution B；
4) solution A and solution B are added in remaining water, stirs, obtain Selenium-rich nutrient solution.
Present invention also offers a kind of application of above-mentioned Selenium-rich nutrient, the application is：When paddy growth enters tiller
During mid-term, Selenium-rich nutrient solution is obtained by Selenium-rich nutrient is soluble in water, then Selenium-rich nutrient solution is sprayed to rice leaf, wherein,
The fountain height of Selenium-rich nutrient solution is 25~35L/ mus.
The beneficial effects of the present invention are：
At normal temperatures, it is of the invention compared to other selenium-enriched fertilizers, with higher stability, while rice can be effectively improved
The content of selenium, makes Se content in rice reach selenium-rich standard, the invention can be applied to the extensive industry metaplasia of selenium-rich rice in rice
Production.It in addition, potassium dihydrogen phosphate and ammonium nitrate can provide N, P, K indispensable element for plant in formula, can increase the yield of crop
Plus 10-15%；Chitosan is a kind of stronger chelating agent, can not only suppress the absorption of plant heavy metal, can also be increased
The adhesive force of blade, makes the fertility of the beneficial elements such as selenium more longlasting.This patent combination practical experience, is added quantitative into formula
Add quality in chitosan, potassium dihydrogen phosphate and ammonium nitrate, every 15L solution for 1.5g, 3.5g and 5.5g, i.e., respectively 15 parts,
35 parts and 55 parts.At present, the Selenium-rich nutrient has carried out the mid-term that area is about 100 mu, 500 mu and 1000 mu in continuous 3 years
Experiment, and yield good result, the rice Se content produced reaches more than selenium-rich standard.
Embodiment
In order to preferably explain the present invention, below in conjunction with the specific embodiment main contents that the present invention is furture elucidated, but
Present disclosure is not limited solely to following examples.
Embodiment 1
Produce the preparation method of the Selenium-rich nutrient solution 1 of selenium-enriched rice：
First, 0.1g sodium selenites and 1.5g chitosans are weighed, component A is made into；Weigh 3.5g potassium dihydrogen phosphates, 5.5g nitre
Sour ammonium, 3.0g glycine, it is selenium-rich nutritive agent prescription to be made into component B, component A and component B.Before use, distinguishing at normal temperatures
With 100ml water stirring and dissolvings, solution A and solution B are configured to, it is stand-by；Then, in the tillering stage of paddy growth, by the molten of preparation
Liquid A is imported in the running water for filling about 2L and stirred, and is continuously added running water to 8L, solution B is poured into above-mentioned 8L solution
Continue to stir, it is Selenium-rich nutrient solution 1 to be diluted to 15L, standby.
Following experimental procedures are：Paddy growth enters middle of tillering, Selenium-rich nutrient solution 1 is sprayed to rice leaf, often

3 experimental cultivation areas are chosen, 4 pieces of experimental plots have been related separately to, wherein the scale in every piece of experimental plot is 5m × 5m, examination
Test field and be spaced about 0.5m.Base fertilizer applies composite fertilizer's (25kg/ mus), urea (10kg/ mus), potassium application (5kg/ during dry field rehydration
Mu).Treat that paddy rice enters physiological maturity, the paddy rice in every piece of region is plucked using artificial using scissors to spike of rice, takes back reality
Test room processing.
Rice Se content (μ g/g) in the experimental plot of table 6
As a result (table 6) is shown, the content of selenium is in after first raising with the increase of glycine quality in Selenium-rich nutrient in rice
The trend tended towards stability, wherein test group (glycine2.0) rice Se contents reach 0.206 μ g/g, more than selenium-rich rice mark
It is accurate.Meanwhile, test group (glycine3.0) rice Se contents be up to 0.273 μ g/g (selenium-rich rice standards：Se content >=
0.1 μ g/g), and test group (glycine4.0) rice Se content is basicly stable, is 0.276 μ g/g, therefore glycine quality is
During 3.0g, best results.
Other unspecified parts are prior art.Although above-described embodiment is made that to the present invention and retouched in detail
State, but it is only a part of embodiment of the invention, rather than whole embodiments, people can also according to the present embodiment without
Other embodiment is obtained under the premise of creativeness, these embodiments belong to the scope of the present invention.
