Description
A kind of selenium-enriched fertilizer of the present invention and be used for the production method of selenium-rich rice belongs to the Se-enriched bio preparation, is exclusively used in the production of Se-rich farm products.
Selenium is the essential micronutrient element of animal and human's class.The international selenium recommendation daily intaking amount 60-400 μ g of association, daily intaking amount 50-200 μ g recommends in Chinese Soclety of Nutrition.And according to China's nutrition survey, the selenium intake of being grown up every day is 26-32 μ g only.Therefore, the population of China selemium nutrition is bad is common problem.China lacks selenium soil and accounts for 72% of national area, lacks selenium population and reaches more than 100,000,000.The many region of China disease occurred frequently, as Keshan disease, Kaschin-Beck disease, cancer, cardiovascular and cerebrovascular diseases, diabetes, infertility, immunity of organisms go down with aging course etc. 40 surplus kind of disease all with meals in the selenium picked-up not enough relevant.And day by day under the serious situation, selenium has special physiological functions such as the heavy metal poisoning of releasing in environmental pollution.U.S. scientist 1999 research proves that also the scarce consumption of selenium is the universals of aids patient in the body.Therefore, human body is mended the requirement that selenium does not still improve immunizing power, also is the effective way that strengthens the resistibility of environmental poisonous substance; Selenium in the natural food can not satisfy the normal need of human body, and economic, efficient, safe selenium-enriched food is human effective way of mending selenium.
At present, " selenium yeast " of U.S. exploitation, kind deposit (Centrum) selemium nutrition additive and domestic " rich selenium health ", " health must selenium " though etc. product belong to biological technology products, but do not meet the food consumption present situation that big area lacks the selenium crowd, more can not become effective the replenishing that lacks the human selemium nutrition in selenium area.The academician such as Lu Liangshu, Li Zhensheng are pointed out; improving food chain selenium level is the basic outlet of regulating and control selemium nutrition and the relevant selenium deficiency disease of prevention from the source; and appeal to strengthen the Se-rich farm products exploitation, and by common crop production selenium is organised, set up the human selemium nutrition pattern of daily ingestion of food; strengthen rich selenium foodstuffs production; have important commercial and economic worth, and build up people's health especially, (Lu Liang pardons the academician to the needs of protection people ' s health; the green food communication, on June 20th, 1999).China's 60% population is edible, and the protein of its 50-70% is from rice, and southern area rice selenium content is low, and it is very serious to the threat of human health to lack selenium.Overwhelming majority place, Jiangsu is to lack the selenium area, and Qidong liver cancer, Yancheng lung cancer, intestinal cancer and mammary cancer etc. are all relevant with the scarce selenium of local people's meals.The rice industrialization has vast potential for future development, (main consideration does not have, less contamination to rest on green food at present, edible safety), functional food and dietetic product industrialization do not start to walk yet, mend selenium and be significant for improving the people ' s health level, the selenium-enriched health care development of agricultural products has vast market prospect.
Animal is mended selenium and makes an addition to food with Sodium Selenite in the past, but its biological effectiveness is low, and absorption scope (50-400 μ g/ days) is narrow, easily produces excess intake and the problem of poisoning.Sodium Selenite soil application and foliage-spray, because of soil fixing and a large amount of drift, not only selenium validity is low, and security and less economical, so can not become the benefit selenium measure that agricultural-food are produced.Selenium is generated interior absorption selenium-enriched fertilizer by biotechnical processes, can effectively be absorbed by plant, thus the safe and efficient production of realization Se-rich farm products.Quality nutrient is the latest tendency of current plant nutrition research, selenium is the up-to-date focus of attention (the Li Zhensheng academician of plant nutrition research, in November, 1999 state natural sciences fund 21 century core problem in science discussion), multicomponent composite trace element preparation had positive effect in the past, and entered industrialization, products such as foliage fertilizer have begun to take shape, and domestic still do not have a Se-enriched bio preparation, can not satisfy the needs of Se-rich farm products.
The purpose of this invention is to provide a kind of selenium-enriched fertilizer and be used for the production method of selenium-rich rice, low at selenium validity in the prior art, and security and less economical, the defective of the benefit selenium measure that the shortage agricultural-food are produced, produce the Se-enriched bio preparation, satisfy the production needs of Se-rich farm products.
A kind of selenium-enriched fertilizer provided by the present invention is to produce by the following method:
(1) by weight, pig manure 2-3 part, silkworm faeces 1-2 part, human excrement 0.5-1 part, rapeseed cake (or soybean cake) 0.5-1 part are dropped into fermentation vat, add water 1-2 part, add a cover fermentation 40-50 days, extremely slightly frowziness;
(2) add water 8-9 part, continue fermentation 20-40 days, the solids component to batching dissolves;
(3) get fermented liquid 100-200 order and filter, get the selenium-enriched fertilizer mother liquor;
(4) add Sodium Selenite or sodium selenate 5-10kg by the 100kg mother liquor, dissolve and stir, do not have precipitation, after reacting completely selenium-enriched fertilizer get final product can.
The selenium-enriched fertilizer of above-mentioned acquisition is stored concentration and is counted 20-46g/L with the selenium element.
Selenium-enriched fertilizer provided by the present invention is used for the production method of selenium-rich rice, comprising:
At the paddy rice full heading time, the choosing cloudy day, or after fine at 4 o'clock in afternoon, every mu Di add with the 100ml selenium-enriched fertilizer
Water 400-500 sprays after doubly diluting; Spray in back 24 hours in case of raining, fill spray 1 time.
Selenium-enriched fertilizer provided by the present invention and be used for the production method of selenium-rich rice, its advantage and positively effect are:
1) selenium-enriched fertilizer can significantly improve the rice selenium content
Selenate, selenite combine with humic acid (HA), can prolong the duration of contact on selenium and blade face, thereby help the absorption of plant to selenium.Table 1 is the result show, two kinds of biological selenium fertilizer of foliage applying selenate and selenite can significantly improve the rice selenium content, and the selenium-rich rice selenium content is brought up to 0.267mg/kg, and do not influenced the output of rice from the 0.071mg/kg of contrast.The rice selenium content of selenate and two kinds of fertilizer productions of selenite does not have significant difference.
