Description
Technical field
The present invention relates to field of agricultural cultivation, and in particular to a kind of implantation methods of selenium-rich gynostemma pentaphylla.
Background technology
Gynostemma pentaphylla is Curcurbitaceae gynostemma pentaphyllum genus herbaceous perennial vine climber plant, belongs to medicinal and edible plant, more with complete
Grass is used as medicine, have the effect of QI invigorating, calm the nerves, hypotensive, " elixir grass " for being called " mystery " among the people, national star in 1986
Fire is classified as the first place of " rare traditional Chinese medicine " in the works, and medicine-food two-purpose kind list is listed in by the Ministry of Public Health within 2002, and it is opened
Hair has a high potential.There is abundant gynostemma pentaphylla resource enshi, has 11 kinds of gynostemma pentaphylla plants, accounts for world's category kind and mutation
61.1%, account for the 78.6% of the national category kind and mutation.Last century the nineties, Hubei Institute For Nationalities's seed selection gynostemma pentaphylla new product
Plant " leaf of grace seven is sweet ", its active ingredient and nutrient composition content are higher, taste sweet gas is fragrant.It is the strand of Raw material processing with " leaf of grace seven is sweet "
The blue tea of stock, colour and lustre is green, sense organ is splendid；Sweet, in good taste, not stimulating intestine and stomach, medical value is high, and market development Utilization prospects are wide
It is wealthy.
Selenium is the essential trace elements of the human body, and it is anti-oxidant that research confirms that selenium has, and removes free radical, pre- anti-cancer, beauty treatment
It is anti-ageing, immunologic function is adjusted, participate in the important function such as the synthesis of human body multiple proteins.AAN is classified as selenium
The biological element of equal importance with vitamin, the carrotene of B mono-.There is scientist to foretell " selenium will change the world ", it is seen that selenium is for people
The influence of class health.
Bestowing favour has the unique independent Se fractionation in the world, selenium aboundresources, but selenium resource is not evenly distributed, and causes artificial
The gynostemma pentaphylla Se content of plantation is unstable, it is impossible to the quality safety of effective guarantee gynostemma pentaphylla selenium product, stabilization, controllable.
The content of the invention
It is an object of the invention to provide a kind of implantation methods of selenium-rich gynostemma pentaphylla.
A kind of implantation methods of selenium-rich gynostemma pentaphylla of the present invention, it is characterised in that comprise the steps of：
(1) selection of land site preparation：
Plot of the selection soil Se content higher than 5mg/kg, in winter or early spring in next year site preparation, turns over, and depth is 25-
30cm, inclined slope aspect or north-south bedding, furrow 1.2m wide, furrow width 0.3m make base manure with the farm manure for becoming thoroughly decomposed, and every mu of consumption is
2000-3000kg, base manure applies rear blinding 5cm；
(2) sow：
Sow and fruit is taken out in the last week, pericarp is removed in stranding, choose brown mature seed, 25 DEG C of constant temperature seed soaking 16h are pulled out and dried in the air
Solid carbon dioxide point can be sowed, and mid or late March is live, and shallow ridges drilling is opened by-the 40cm of line-spacing 30, and mu application rate is 1.5-2kg, and will be planted
Fine sand of the son with 5 times is mixed, and is uniformly sprinkled into ditch, and-the 2cm of earthing 1 is watered, and ground moistening is kept to before emerging；
(3) field management：
A, thinning final singling：When seedling is long when having 2-3 true leaves, by-10cm the thinnings of spacing in the rows 6；During height of seedling 15cm, by spacing in the rows
15-20cm final singlings；
B, tillage and weeding：Carried out in the non-Feng Hangqian of plant, shallow hoe is noted during operation, in order to avoid damage young subterranean stems；
C, pinch：Fine day is taken advantage of when stem grows to 30-40cm to pinch, top 3-4cm is plucked, and is pinched in year 2 times；
D, built shade：Gynostemma pentaphylla seedling stage avoids high light direct projection, can between plant and corn or take l -1.5m framves high, overlying with bamboo pole
Shade thing；When vines grow to 50cm, human assistance restocking；
E, fertilising：Apply 1 natural pond fertilizer within 1 week after final singling, gather in every time or be intended to chase after 1 natural pond fertilizer after pinching, to avoid burn seedlings from showing
As natural pond fertilizer is fermentation biogas slurry, by 1:4 dilution proportions, the application method of fertilizer should meet the requirement of NY/T394；
F, irrigation and drainage：May to September plant strain growth it is vigorous when, often water, keep ground moistening, rainy season wants timely draining, in order to avoid
By flood；
(4) selenium-enriching cultivation：
When soil Se content is less than 5mg/kg, with the artificial selenium-supply of selenium-enriched foliage fertilizer that selenium content is 200mg/kg, in 5-June
Growth animated period sprays 2 selenium-enriched foliage fertilizers, and every mu of consumption is 50kg, and administered twice interval is 1 month；
(5) prevention and control of plant diseases, pest control:
A, southern blight：Sprayed with 50% thiophanate-methyl, 800 times of liquid and prevented and treated, every 7-10d is sprayed 1 time, continuous 2-3 times；
B, powdery mildew：Sprayed with 50% thiophanate, 500-800 times of liquid and prevented and treated, every 7-10d is sprayed 1 time, continuous 2-3 times；
C, subterranean pest-insect：Mainly black cutworm and grub, Winter-Spring removing ground weeds, dry branches and fallen leaves, eliminate the children that survives the winter
Worm and pupa, seedling stage can be sprayed with 2.5% deltamethrin milk oil, 2000 times of liquid；
D, mollusk：Mainly snail and slug.Seedling stage is sprayed with 25% carbaryl wettable powder, 500-1000 times of liquid
Mist, or mix wheat bran trapping with 10% imidacloprid, 1500 times of liquid；
(6) harvest:
In 6-July gynostemma pentaphylla Feng Hanghou, start to adopt stem apex or climax leaves.
A kind of implantation methods of selenium-rich gynostemma pentaphylla of the present invention, it is characterised in that described gynostemma pentaphylla is Hubei Province's farming article
Plant the gynostemma pentaphylla new varieties " leaf of grace seven is sweet " of validation board's authorization；Twisted from Curcurbitaceae gynostemma pentaphyllum genus herbaceos perennial
Stock indigo plant Gynostemma pentaphyllum (Thunb.) Makino.
The present invention selects suitable gynostemma pentaphylla selenium-enriching cultivation technology for different soils selenium background of bestowing favour.Selection Selenium in Soil
Plot plantation gynostemma pentaphylla of the content higher than 5mg/kg, can reach gynostemma pentaphylla selenium-rich effect.When soil Se content is less than 5mg/kg,
Gynostemma pentaphyllum stem leaf site is sprayed in the selenium-enriched foliage fertilizer that 5-June selenium content is 200mg/kg, every mu of consumption is 50kg, is applied twice
It it is 1 month with interval.Selenium-enriched foliage fertilizer is made up of boric acid, potassium dihydrogen phosphate, zinc sulfate, sodium selenite etc., and Se content is
200mg/kg。
A kind of implantation methods of selenium-rich gynostemma pentaphylla of the present invention have the beneficial effect that：
1st, in the resourceful region of Selenium in Soil, selection selenium-rich soil carries out artificial growth gynostemma pentaphylla, is capable of achieving gynostemma pentaphylla
It is the steady quality of selenium product, safe, controllable.
2nd, in the region of Selenium in Soil inadequate resource, gynostemma pentaphylla selenium-rich can be realized by spraying the artificial selenium-supply of selenium-enriched foliage fertilizer
Effect.
3rd, the implantation methods of selenium-rich gynostemma pentaphylla of the present invention, operation is simple, is easy to promote.
4th, the gynostemma pentaphylla of present invention plantation, Se content reaches 0.2-1mg/kg.
