Description
Technical field
The present invention relates to fruit and vegetable fertilizer field, particularly relate to one and be used in the fructovegetative fruit and vegetable selenium-enriched fertilizer of the rich selenium of scarce selenium culturing on soil.
Background technology
Selenium (Se) is a kind of trace element, and molecular weight is 78.96, is positioned at VIA race in the periodic table of chemical element, and chemical property is similar to element sulphur of the same clan.Current prevailing paradigm is thought, selenium appropriate in diet is kept fit to human body and had vital role.First, selenium plays irreplaceable effect in the resistance of oxidation improving human body.In addition, selenium also has anticancer, liver protecting, in conjunction with the important physiological function such as heavy metal, prevention and cure of cardiovascular disease.Meanwhile, the important origin cause of formation of selenium or mankind's Kaschin-Beck disease, Keshan disease is lacked.
1973, the World Health Organization (WHO) determined that selenium is necessity trace element of humans and animals vital movement, and rear recommendation adult selenium intake every day should reach 50-200 μ g/ days, and maximum intake is no more than 400 μ g/ days.1991, specify in the GB13105-91 selenium in food tolerance limit that China promulgates, grain≤300 μ g/kg, bean product≤300 μ g/kg, vegetables≤100 μ g/kg, fruit≤50 μ g/kg, eggs≤500 μ g/kg, meat (livestock and poultry)≤500 μ g/kg, fish≤500 μ g/kg, fresh milk≤30 μ g/kg.
Selenium plays an important role to plant-growth, HUMAN HEALTH as important trace element.But inorganic selenium can not directly absorbed by the bodyly utilize.And plant is by transforming, the inorganic selenium in physical environment can be changed into organoselenium.Therefore, plant, as important selenium conversion person, is the important sources that mankind's selenium is taken in.
But except the minority areas such as enshi, the Bashan Mountain, Shaanxi, Yichuan find high-Se soil, the scarce selenium soil erosion of China reaches 72%.Its people still can not reach recommendation to the intake of this useful trace element of selenium.Therefore, just become at scarce selenium grown on soil rich selenium vegetables the large problem that investigator faces.
Traditional selenium-enriched fertilizer application sodium selenate carries out selenium-enriching cultivation as selenium source.But sodium selenate is a kind of severe poisonous chemicals, very easily causes comparatively major injury to the health of operator aborning.Meanwhile, do not done by plant the residual sodium selenate absorbed and can cause very large threat to the health of human consumer.
On the other hand, in existing selenium-enriched fertilizer, except selenium constituent content is higher, all the other nutritive element contents are less, even completely must trace element containing certain plants growth institute.This type of selenium-enriched fertilizer of single use, all can affect greatly the seed output and quality of vegetable.And if use other fertilizer more in addition and not only can strengthen purchase cost, also can increase cost of labor.
3rd, traditional selenium-enriched fertilizer much needs to be applied directly in the middle of soil.On the one hand, the selenium element in fertilizer along with pouring water in the middle of leaching loss to deep soil, can be unfavorable for the utilization of vegetables, also can cause the waste of fertilizer.On the other hand, the heavy metal element in fertilizer constantly can be accumulated in the middle of anthropogenic soil along with using, and then finally enters in plant materials, causes potential harm to the safety of vegetable.
Summary of the invention
Based on the problem existing for above-mentioned prior art, the invention provides a kind of be applied to the cultivation of rich selenium fruit and vegetable efficient, high-quality, safely, be beneficial to the fruit and vegetable selenium-enriched fertilizer of popularization.
For solving the problems of the technologies described above, the invention provides a kind of fruit and vegetable selenium-enriched fertilizer, this selenium-enriched fertilizer consists of the following composition:
When above-mentioned fruit and vegetable selenium-enriched fertilizer uses, dilute with water 150 doubly to 250 times.
Beneficial effect of the present invention is: in this selenium-enriched fertilizer, application Sodium Selenite, and does not adopt sodium selenate, has evaded the health threat of fertilizer to producers and consumers itself.In addition, except with the addition of enough selenium fertilizer, also for fructovegetative regulation of fertilizer requirement, with the addition of the necessary nutritive element such as the necessary nitrogen of plant, phosphorus, potassium, iron, magnesium, copper, zinc, serve the function of saving of work and time, a fertile multiple-effect.This selenium-enriched fertilizer can be used as foliage fertilizer and uses, and is not only more conducive to the quick absorption of plant, also reduces the disadvantageous effect of fertilizer to soil.Especially for the fruit type vegetable of Long term cultivation as tomato, cucumber etc., impose foliage fertilizer and its growth potential of guarantee, output, quality more played a very important role.Fruit and vegetable fertilizer rich in selenium of the present invention, not only has important effect to the production of rich selenium fruit and vegetable, and its use convenience, safety, cost lower, be beneficial to popularization, have a extensive future.
