Description

Selenium-rich oranges and tangerines fertilizer

Technical field

The present invention relates to a kind of field of planting, more particularly to a kind of selenium-rich oranges and tangerines fertilizer.

Background technology

Selenium (Se) is a kind of trace element, and molecular weight is 78.96, and Group VIA is located in the periodic table of chemical element, Chemical property is similar to element sulphur of the same clan.Current prevailing paradigm thinks that appropriate selenium is to human body in diet Keep fit with important function.First, selenium plays irreplaceable in terms of the oxidation resistance of human body is improved Effect.In addition, selenium is also with anticancer, liver protecting, with reference to the weight such as heavy metal, prevention and cure of cardiovascular disease Want physiological function.Meanwhile, lack selenium or mankind's Kaschin-Beck disease, the important origin cause of formation of Keshan disease.1973, generation Boundary's health organization (WHO) determines that selenium is necessary micro-, the pusher of humans and animals vital movement Recommending the daily selenium intake of adult should reach 50-200 μ g/ days, and maximum intake is less than 400 μ g/ days.1991 Year, 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 as important trace element to plant growth, health.But inorganic selenium Directly absorbed by the body can not utilize.And plant can be converted the inorganic selenium in natural environment by conversion Into Organic Selenium.Therefore, plant, as important selenium conversion person, is the important sources of mankind's selenium intake.However, In addition to the minorities such as enshi, the Shaanxi Bashan Mountain, Yichuan area finds high-Se soil, the scarce selenium of China

Soil erosion has reached 72%.National beneficial micro- intake this to selenium can not still reach recommendation Value.Therefore, the big problem that researcher is faced just is become in scarce selenium grown on soil rich selenium vegetables.Pass The selenium-enriched fertilizer application sodium selenate of system carries out selenium-enriching cultivation as selenium source.However, sodium selenate is a kind of severe toxicityization Product, easily cause compared with major injury aborning to the health of operator.Meanwhile, absorption profit is not done by plant The sodium selenate of residual can cause very big threat to the health of consumer.On the other hand, existing selenium-rich In fertilizer, in addition to selenium element content is higher, remaining nutritive element content is less, or even is entirely free of some plants Thing growth institute must trace element.It is single using such selenium-enriched fertilizer, the yield and quality of vegetable all can be made Into considerable influence.And if still further applying other fertilizer can not only increase purchase cost, can also increase artificial Cost.3rd, traditional selenium-enriched fertilizer much needs to be applied directly in the middle of soil.On the one hand, in fertilizer Selenium element can also can cause fertilizer with pouring water and leaching loss is unfavorable for the utilization of vegetables in the middle of deep soil The waste of material.On the other hand, the heavy metal element in fertilizer can constantly be accumulated in anthropogenic soil with applying It is central, and then enter eventually into plant body, potentially hazardous is caused to the safety of vegetable.Except with the addition of foot The selenium fertilizer of amount is outer, is also directed to fructovegetative regulation of fertilizer requirement, with the addition of nitrogen necessary to plant, phosphorus, potassium, The necessary nutrient such as iron, magnesium, copper, zinc, serves saving of work and time, the function of a fertile multiple-effect.This richness Selenium fertilizer can be applied as foliage fertilizer, and not only the more conducively quick absorption of plant, also reduces fertilizer to soil Adverse effect.Particularly with fruit type vegetable such as tomato, cucumber etc. of Long term cultivation, foliage fertilizer pair is imposed Ensure that its growth potential, yield, quality are more played a very important role.The fruit and vegetable selenium-rich fertilizer of the present invention, no Only the production of selenium-rich fruit and vegetable is played the role of it is important, and its apply convenience, safety, cost is relatively low, be beneficial to Promote, have a extensive future.

The content of the invention

In view of this, it is an object of the invention to provide a kind of selenium-rich oranges and tangerines fertilizer, in Ci trus growth process In Se-enriched bio-organic fertilizer is enriched to soil, by inorganic selenium element import oranges and tangerines tree body in, by oranges and tangerines itself Life movement, is organic nutrition by inorganic selenium cycling of elements, makes organic selenium content improve the content for reaching needs, The content of selenium is up to 3.8-4.8mg/kg after fruit maturation, allocates by product standard quality, makes fruit product begin Stabilised quality is kept eventually, reaches qualified products requirement

The selenium-rich oranges and tangerines fertilizer of the present invention, the organic fertilizer raw material includes by weight following components：8-16 Part fermentation poultry dung, 5-15 parts fermentation mushroom bran, 1-6 part medical stones, 5-15 part oil cake of flax seed containing selenium, 3-12 parts Pine needle meal, 4-8 part diatomite, 3-8 part Chinese medicine slags, the dry maggot powder of 2-6 parts；

Further, the organic fertilizer raw material includes by weight following components：12 parts of fermentation poultry dungs, 10 parts send out Yeast-like fungi chaff, 4 parts of medical stones, 10 parts of oil cake of flax seed containing selenium, 6 parts of pine needle meals, 5 parts of diatomite, 6 parts of Chinese medicine slags, 4 parts of dry maggot powder；

Further, the Chinese medicine slag is at mother chrysanthemum, honeysuckle, the mixture of selfheal and Jing high-temperature aerobic fermentations Reason.

Beneficial effects of the present invention：The selenium-rich oranges and tangerines fertilizer of the present invention, to soil during Ci trus growth Se-enriched bio-organic fertilizer is enriched, inorganic selenium element is imported in oranges and tangerines tree body, by the life movement of oranges and tangerines itself, It is organic nutrition by inorganic selenium cycling of elements, makes organic selenium content improve the content for reaching needs, fruit is ripe Afterwards the content of selenium is up to 3.8-4.8mg/kg, allocates by product standard quality, makes fruit product remain steady Determine quality, reach qualified products requirement.
