Description
Technical field
The present invention relates to a kind of iodine planting method of carrot that contains.
Background technology
Iodine is the trace element of needed by human, it plays a part very important in the metabolic processes of human body, iodine in the human body has more than 1/3rd and exists with thyroid form, in the thyroid gland of each molecule, 3 or 4 iodine atoms must be arranged, there is not iodine, thyroid gland just can not the synthetic thyroid element, thyroxine has the synthetic of promotion protein, activates 100 plurality of enzymes, regulates power conversion, tachyauxesis and growth, keep the biological agents such as structure of central nervous system, so the human body iodine deficiency can cause a series of physiologic derangements and biological function unusual, as cause goitre and cretinism, baby's iodine deficiency when growing particularly, can cause intelligence disability, this because iodine deficiency and, be called as " IDD(Iodine deficiency disorders) " to whole influences that human body caused (IDD).
Statistics according to the epidemiology survey and the World Health Organization, because of the environmental background content of some areas iodine very low, whole world All Countries except that Iceland all has IDD popular, nearly 1,600,000,000 people in the whole world are subjected to the threat of iodine deficiency, in state-owned 4.25 hundred million people live in Iodine Deficiency Area, interrelated data according to health ministry, China's intelligence disability philtrum has more than 80% because iodine deficiency causes, because IDD seriously influences human life and health, therefore, human body enriches the iodine becomes a public health problem of global range.
Salt adds iodine and is considered at present prevent and treat the easy and the most economical and the most practical method of IDD, is generally adopted by various countries.Since 80 years last century, the Chinese government taked the measure of the edible iodizedsalts of the whole people, has obtained good effect.But in practice for many years, also expose this measure and have some obvious defects: the one, the inorganic iodine that adds in the salt is volatile, part iodine can lose in storage, transportation and gastronomical process, thereby the iodine concentration that adds in the salt is difficult to control, in addition, there is tangible individual difference in human body to the absorption of inorganic iodine in the salt, to such an extent as to the difficult biological effectiveness of assessing it quantitatively; The 2nd, the iodine in the organism has the characteristics of dual threshold, be that high iodine or low iodine all can produce heterogeneity and biological effect in various degree to body, high iodine is taken in and can be caused a disease equally, studies show that thyroid cancer is also relevant with too much absorption iodine, all ages and classes and different classes of crowd are (as children, the adult, pregnant woman and wet nurse) every day the requirement to iodine very big-difference (table 1) is arranged, carry out Universal saltiodization when the people who gives real iodine deficiency enriches the iodine, also will be to the people of iodine deficiency even the people of minority iodine excess intake do not enrich the iodine by force, show according to interrelated data, high iodine illness incidence increases China recent years because of the iodine excess intake makes, and is spreading trend; The 3rd, at serious iodine deficient area, in case stop iodizedsalt, the illness rate of IDD will rise, and this explanation salt adds iodine, and this is a kind of temporary transient rather than measure permanent and that fundamentally improve the iodine deficiency situation.For this reason, reach the final goal of thorough elimination IDD, except salt added iodine, we need seek the more mode that enriches the iodine of science health.

Existing studies show that, under natural situation, 75%～85% iodine is from vegetable food in the human body, and by from vegetable food naturally the mode of picked-up organic iodine more help keeping the balance of human body iodine, this is because human body reaches as high as 99% to the bioavailability of iodine in the variety classes food.The present invention makes solid iodine fertilizer or liquid iodine fertilizer according to the Biogeochemistry principle of transfer with the marine alga of rich iodine, by the mode that soil is executed and sprayed, cultivates the carrot that contains iodine.Carrot has the title of " glabrousleaf asiabell root ", it is except containing carbohydrate, protein, fat, vitamin, volatile oil, and more potassium, calcium, phosphorus, outside the mineral salt such as iron, also contain abundant carotin, carrot is comprehensive nutrition not only, and also has good medical function, the vitamin A that is rich in the carrot has the body normal growth of promotion and breeding, keep epithelial tissue, the control respiratory tract infection, functions such as treatment nyctotyphlosis and ophthalmoxerosis, carrot can strengthen the immunity of human body, antitumaous effect is arranged, the women carrot of taking food can be lowered the incidence of disease of oophoroma, carrot includes Potassium Suceinate, helps to prevent vascular sclerosis, cholesterol reducing, carotin can be removed the free radical that causes people's aging, have antidotal effect, in addition, the aromatic odor of carrot is that volatile oil produces, it can promote digestion, and the effect of sterilization is arranged.Just because of this, carrot becomes favorite a kind of vegetable food in people's daily life, edible contain the iodine carrot and not only can supplement the nutrients, be of value to healthy, and can be used as the natural source that a kind of effective food of human body enriches the iodine, this has important practical significance to preventing and treating IDD(Iodine deficiency disorders) (IDD).
Summary of the invention
The purpose of this invention is to provide a kind of iodine planting method of carrot that contains.
Containing the iodine planting method of carrot comprises the steps:
1) selects the carrot new seed of suitable, high yield of ripe phase, high-quality with suiting measures to local conditions, seta on the seed is rubbed, in 38～40 ℃ warm water, soaked 2～2.5 hours, place then under 20 ℃～25 ℃ the temperature, keep suitable humidity, vernalization 3～4 days when seed shows money or valuables one carries unintentionally, can be sowed.
2) select that physical features is higher, draining is good, soil layer is deep, quality is loose, the content of organic matter is high, free of contamination loam or sandy loam, open the railway carriage or compartment and do furrow, existing 10～20% carrot seeds that show money or valuables one carries unintentionally are admixed in an amount of fine earth equably, carry out drilling, 20～25 centimetres of line-spacings, 1～2 centimetre of seed level, sowing time was preferably arranged in after morning or at 4 o'clock in afternoon, after planting water sufficient moisture, earthing is wanted evenly not reveal seed, broadcast back furrow face and cover stalk things such as rice wheat, and covering drenched, when seedling is unearthed, in time remove covering between the lights.
3) the preceding thinning of final singling is 2 times, when about 3 centimetres of heights of seedling, during 1～2 true leaf, carries out the thinning first time in conjunction with weeding; When 4～5 true leaves, carry out the thinning second time, dredge and went close stand, weak seedling, weak plant and diseased plant, final singling when 5～6 true leaves, 7～10 centimetres of spacing in the rows.
4) before the carrot seed is seeded in the field, use sufficient base manure, and with the disposable top layer that is manured into soil of solid iodine fertilizer, the amount of application of control solid iodine fertilizer is 12mg/m
2～150mg/m
2, the carrot growing period imposes 2～3 times with composite fertilizer, and carries out the preventing and controlling of intertill and clean tillage and damage by disease and insect.
Perhaps used sufficient base manure before the carrot seed is seeded in the field, the carrot growing period imposes 2～3 times with composite fertilizer.Divide 5～6 times to foliage-spray liquid iodine fertilizer before the carrot receipts are adopted, the blanking time that at every turn sprays is basic identical, and the consumption that sprays of control liquid iodine fertilizer is 12mg/m
2～150mg/m

Embodiment
The sea-tangle of I is rich in utilization of the present invention, make the solid iodine fertilizer or make liquid iodine fertilizer as carrier with low-grade diatomite through soaking technology, and by using the solid iodine fertilizer or spraying liquid iodine fertilizer, cultivate the carrot that contains iodine, people are edible in daily life to contain the iodine carrot, can carry out effective food naturally and enrich the iodine.
Concrete implementation step of the present invention is as follows:
The palmate sea-tangle is a kind of seaweeds phytoplankton in the Laminariaceae, and it can absorb from seawater and a large amount of iodine of enrichment, and the content of iodine generally can reach 0.2%～0.5% of dry weight in the sea-tangle.It is 1～6 millimeter granular that such dried sea-tangle is ground into particle diameter, and crosses the low-grade diatomite of 80～100 purposes, evenly mixes with 1: 1～3 ratio, and then by the squash type comminutor, forming diameter is the granular solids iodine fertilizer of 2-6 millimeter.Low-grade diatomite itself is a kind of inorganic ore deposit fertilizer of mainly being made up of diatom remains and clay mineral; the diatom remains are because of there being special pore structure; and have a characteristic that adsorption capacity is big, can improve the soil and preserve soil moisture; with low-grade diatomite is that the iodine fertilizer of carrier can make the iodine in the sea-tangle slowly discharge; thereby improved the lasting effect of iodine fertilizer; the effect of playing the protection soil moisture content simultaneously and improving the soil; practice shows that suitable diatomite ratio can increase the absorptive amount of crop to iodine in the solid iodine fertilizer.After the solid iodine fertilizer is made, demarcate the content of iodine of iodine fertilizer.
The making of liquid iodine fertilizer: dried sea-tangle and water are soaked with 1: 500～1: 800 ratio, the pH value of soaking water is 6.5～7.5, soaking temperature is 30～50 ℃, soak time is 2～4 hours, by soaking, about 80% iodide ion enters solution in the dried sea-tangle, and soak promptly becomes liquid iodine fertilizer, and the sea-tangle after the immersion can be used as the raw material that continues deep processing.After liquid iodine fertilizer is made, demarcate the content of iodine of liquid iodine fertilizer.
