Description

A kind of implantation methods of the fragrant and sweet shaddock of selenium-rich

Technical field

The present invention relates to a kind of implantation methods of the fragrant and sweet shaddock of selenium-rich.

Background technique

Fragrant and sweet shaddock is more precocious shaddock class breeding.Fruit shape is beautiful, the big thin skin of fruit, matter embrittlement slag, moderately sour and sweet, and fragrance is dense Strongly fragrant, soluble solid is high, and juice multicore is few, full of nutrition, unique flavor, best in quality, is welcomed by consumers.

Selenium is that other substances are irreplaceable to the great function of human health.Selenium deficiency can directly result in human immunological competence Decline, clinical medicine prove, threaten more than 40 kinds of diseases of human health and life all related with human body selenium deficiency.Selenium cannot be in people Vivo biodistribution synthesis, it is necessary to from external intake.It is investigated according to expert, people needs lifelong selenium-supply.Therefore, selenium-supply has become people and chases after Seek a kind of trend and imperative healthy mission of health.For selenium-supply, market is proposed sodium selenite nutrition fortifier Selenium-supply product, but the absorption and utilization of inorganic selenium (such as sodium selenite) be not highly desirable, biological effectiveness is low, it is more toxic, in Range is small between poison amount and requirement, thus is strictly limited its usage amount.By the physiological metabolism of plant or animal, inorganic Selenium is converted to organic selenium, i.e. exploitation Se-rich farm products, is the optimal path of selenium-supply.

Summary of the invention

Place, the present invention provide a kind of implantation methods of fragrant and sweet shaddock of selenium-rich in order to overcome the deficiencies of the prior art.

The present invention is achieved by the following technical solutions:

A kind of implantation methods of the fragrant and sweet shaddock of selenium-rich, which comprises the following steps:

(1) orchard of the fragrant and sweet shaddock of suitable for producing selenium-rich is selected；Select the above own fragrant and sweet shaddock for entering operation period of age of tree life in 5 years Orchard；

(2) prepared by selenium fertilizer: using selenium mineral powder as the selenium source for preparing selenium fertilizer；Selenium fertilizer prepares material composition: its dry weight of cow dung is 70%-80%, its dry weight of agricultural residues powder are 10%-20%, wheat bran or maize flour 5%-10%, composite aminophenol powder 2%-4%, selenium mineral powder 0.1%-0.2%；Above-mentioned substance is uniformly mixed with EM bacterium, water content is adjusted to 45%-50%, piles up Fermentation 30-50 days, during which turning 2 times；

(3) root system applies fertilizer: early March, is digging annular fertilization ditch, furrow width 40 away from Fengdu erythrocyte growth model trunk 80-120 centimeters Centimetre, it is about 30 centimetres deep, it is husky in the ventilating leakage-proof that bottom of trench spreads 2 cm thicks, apply every plant of the selenium fertilizer of step (2) preparation on it 10-20 kilograms, then overburden soil keeps annular fertilization ditch and ground flat；

(4) it foliage dressing: by the selenium fertilizer of step (2) preparation, is impregnated 2-3 days by rich water ratio 1:3, its filtrate is taken to dilute 3-5 Times, in the full-bloom stage of teak late April, the young fruit period of mid-July and August fruit expanding period at blade face foliar spray 4-5 times；

(5) manage: shaddock garden water, fertilizer, disease pest, pruning are identical as other common fragrant and sweet shaddocks.

The beneficial effects of the present invention are:

(1) the fragrant and sweet shaddock fruit selenium content of selenium-rich produced is greater than 20 micro- gs/kg；

(2) production cost is low: conventional method produces rich selenium fruit, and selenium source is usually the inorganic seleniums such as sodium selenite, Price is high, and the present invention is low as selenium source production cost using selenium mineral powder；

(3) easy to operate: fertile selenium production does not need equipment, using conventional organic composting fermentation process, is easy to promote；

(4) utilization rate is high: selenium mineral powder is converted to organic by inorganic states, it is easier to be inhaled by crop by microorganism conversion It receives and utilizes；

(5) will not cause secondary pollution to environment: it is husky that the annular bottom Shi Gou when rhizosphere fertilization uses ventilating leakage-proof Processing, selenium fertilizer will not be lost, and oneself is converted to organic, so secondary pollution will not be caused to environment.
