Background technology
Selenium is a kind of humans and animals trace elements necessary, have remove radical anti-oxidant, delay senility, biological characteristicses such as anticancer, strengthening immunity, antagonism heavy metal.It is 50～250 μ g that a day selenium intake is recommended by Chinese Soclety of Nutrition.The main meals that lean in human body selenium source are taken in, but China adult's average day selenium intake only have about 36 μ g, and therefore, the selemium nutrition condition of poor is at China's ubiquity.The data that WHO announces shows that also the whole world has more than 40 country to belong to low selenium or scarce selenium area.Rich selenium agricultural byproducts are human body supplement selenium element effective ways, and therefore, technique of enriched selenium is scientists study hot of research and development field.
The selenium content of farm crop generally receives the influence of factors such as crop varieties, agronomy control measures, Selenium in Soil content and some physical and chemical index.China belongs to the serious country that lacks selenium, and the whole nation has 70% area all to belong to lack the selenium area approximately.The selenium deficiency of soil has directly caused the deficiency of selenium content in most of regional farm crop, makes China a big chunk crowd be in the selemium nutrition deficiency state.Selenium totally is divided into inorganic selenium and organoselenium two big classes: the former comprises selenate, selenite etc., and inorganic selenium assimilation effect for humans and animals is poor, and risk of toxicity is big, and improper use very easily causes selenosis; The latter mainly is meant the selenium with the biological organic molecule combining form, and the organoselenium specific absorption is high concerning humans and animals, and risk of toxicity is little, is more suitable for mending the requirement of selenium.
The higher direct rice cultivation in area of some Selenium in Soil content of China can be produced selenium content than the higher paddy rice of common regional selenium content.But because also there is the region unhomogeneity in the selenium content distribution in the soil of rich selenium area, this mode of production is quantitatively controlled difficult to the selenium content in the paddy rice, has region limitation and content polytropy, is unfavorable for large-scale standardized production.
Chinese invention patent " selenizing Rice Production method " (application number: 201010570447.4) disclose a kind of urea, Sodium Selenite and boron fertilizer mixing foliage-spray of utilizing and finally made selenium content in the paddy rice reach the method for 200 ~ 300 microgram/kilograms.This method cannot not know that through selenium content stability in the foliage-spray paddy rice selenium content can improve in the final paddy rice.
Chinese invention patent " organic Se-rich rice cultivating method " (application number: 20111019405.4) announced that a kind of utilization contains selenium soil and before paddy rice the method for stubble plantation Herba Astragali Melilotoidis (Herba Astragali Sinici), make in the final paddy rice selenium content at 90 ~ 170 microgram/kilograms.This method can improve selenium content in the paddy rice to a certain extent, but can't promote in the low selenium area of soil, and selenium content has much room for improvement in the paddy rice.
Chinese invention patent " the organic selenium-rich rice of Selenium rich rice rice shoot, its method of cultivation and production " (application number: 201010580228.4) disclose a kind of in the raising rice seedlings stage; Add the method that the nanometer selenium plant nutrient agent is cultivated the Selenium rich rice rice shoot at seedling-cultivation plate soil or seedling Tanaka; Total band selenium amount is 4.6 ~ 360 micrograms/strain during Selenium rich rice shoot transplanting equipment that this method is produced, and the selenium content in the final rice is 100 ~ 300 microgram/kilograms.This kind method has solved the problem of selenium content stability in the paddy rice, but the assimilated efficiency of selenium, and selenium content all has much room for improvement in the rice under not causing paddy rice seedling poisoning prerequisite.
Related patent U.S. Patent No. and document are and relate to high selenium seedling cultivation of rice matrix and utilize it to produce the method for high selenium paddy rice.
Summary of the invention
The objective of the invention is: provide a kind of and be beneficial to rich selenium seedling medium and utilize it to produce the method for high selenium paddy rice.
The technical scheme of seedling medium provided by the invention is following:
Seedling medium with the certain proportion uniform mixing, makes that final sulphur content is 30 ~ 1000 mg/kg in the matrix with soil, humic acids (3% ~ 25%), vitriol and the material that contains biological effectiveness selenium, and biological effectively selenium content is 30 ~ 100 mg/kg.
As preferably, humic acids is 5% ~ 15%, and sulphur content is 80 ~ 800 mg/kg, and selenium content is 40 ~ 80 mg/kg in the final seedling medium.
As preferably, humic acids is 10% ~ 15%, and sulphur content is 160 ~ 600 mg/kg, and selenium content is 40 ~ 60 mg/kg in the final seedling medium.
As preferably, humic acids is 15%, and sulphur content is 240 ~ 300 mg/kg, and selenium content is 40 ~ 50 mg/kg in the final seedling medium.
Wherein, said vitriol is calcium sulfate, vitriolate of tartar, one or more mixing in ammonium sulfate, the sodium sulfate.The material that contains biological effectiveness selenium can be one or more the mixing in selenate, selenite, seleniferous mineral and machining object thereof, the nanometer selenium plant nutrient agent (Suzhou selenium paddy Science and Technology Ltd. produces, product type XGP001A).
The present invention also provides and utilizes this matrix to produce the method for high selenium paddy rice: promptly by behind said components and the good seedling medium of proportional arrangement; Carry out the cultivation of paddy rice seedling and the transplanting and the management of paddy rice seedling according to the routine techniques flow process, finally can gather in the crops the paddy rice of being rich in organoselenium.
Technique effect of the present invention is following: realize the production of final high selenium paddy rice through rich selenium seedling, need make plant accumulate the selenium element of capacity in seedling stage; But simultaneously the selenosis phenomenon can not occur again, promptly will control when seedling stage, paddy rice seedling living weight was smaller toxic action takes place owing to selenium is excessive.
One aspect of the present invention has added an amount of SO in matrix
4 2-Make sulphur and matrix in the young rice seedlings growth process with selenium certain antagonistic action takes place, make that the selenium in the seedling is unlikely to accumulate the degree of poisoning that produces, simultaneously in constantly increase process of seedling later stage living weight; Added sulfate radical is absorbed by plant basically; Thereby no longer the absorption of selenium is produced antagonism, help the higher selenium of paddy rice seedling accumulation, thereby realize finally accumulating the production Selenium rich rice through seedling.
Added humic acids among the present invention on the other hand, can adsorb and contain the selenium material, had certain slow release effect, thereby reduced seedling stage excessive selenium fertilizer, the selenium supply of long period is provided in the seedling growth and development process the infringement of seedling; Humic acids can also promote the raising of selenium assimilated efficiency simultaneously, is beneficial to the exploitation of high selenium paddy rice.
The combination of above-mentioned two kinds of technique means efficiently solves the actual Development and Production of high selenium paddy rice in risk and the later stage cultivating process of seedling cultivation of rice phase selenosis, has important economic value.
