Description
Technical field
The present invention relates to a kind of konjak cultivation technology, specifically a kind of selenium-enriched konjac stereo cultivating method belongs to plant
Object cultivation field.
Background technique
Konjaku, scientific name Dang Konjac belong to Araeceae, herbaceos perennial.There is long cultivation on the south China the Changjiang river
History, it is more than 3000 years existing away from the present.The main component of konjaku is glucomannans, is a kind of ultralow heat, and thin fluid albumen is high
The health food of fiber, and it is rich in ten several amino acid, the vitamin, minerals of needed by human body, as functional food, to height
Blood pressure, hyperlipidemia, diabetes, constipation have certain curative effect.The plenipotentiary of the seventh-largest nutrient of human body, its intake with
Health is closely bound up, is the health food that World Health Organization of the United Nations determines.Number of patent application 201310621802.x is disclosed
A kind of selenium-rich, zinc-rich, rich calcium konjaku cultural method, it is intended that improve the healthy nutritive value of konjaku.It has a defect that
Pest and disease damage is very high when cultivation, and total crop failure is not can avoid, and acid soil konjaku cannot survive at all;In addition the purpose of cultivating konjak
Be obtain glucomannan particle, not the cultivation of economic benefit all indulge in empty talk.
Mainly have two verieties currently on the market: one kind is white konjaku, is mainly distributed on Drainage Area of Jinsha River, such as Sichuan Province
Pingshan County, Leibo County, Jinyang County, Yunnan Province Yongshan County.Another kind of is elephant-foot yam, distributed more widely, as Yunnan, Guizhou, Sichuan,
There is large batch of cultivation in the mountain areas such as Chongqing, Shaanxi, Hubei, because konjaku has three happinesses three fearness: negative, fertilizer favorite, the hygrophilous profit of happiness；Fearness acid,
Stain afraid of water is afraid of high temperature, these features bring no small difficult, wherein most distinct issues to production:
(1) because high temperature leads to the generation of soft rot and southern blight, No kernels or seeds are gathered, as in a year of scarcity；
(2) the hayashishita konjaku cropping pattern several years ago promoted, although disease incidence is lower, yield is very low, per mu yield is
1000 jin, economic benefit does not catch up with the needs of development；
(3) selenium content is few, and selenium is lost more in process；
(4) it is not high to be processed into konjaku dry plate grade；
(5) fine powder stain, Huang Dianduo are processed, viscosity is low；
(6) processing konjak series foods yield rate is low.
Summary of the invention
To solve the above-mentioned problems, it the present invention provides a kind of stereo cultivating method of selenium-enriched konjac, is issued with realizing
Improving eyesight:
(1) konjaku that the present invention cultivates, every kilogram of fresh taro reach 0.88-1.5mg/kg containing selenium element, contain in every kilogram of fine powder
Selenium reaches 3.08-5.25mg/kg；
(2) stereo cultivating method of the present invention, economic benefit is up to 20000 yuan or more per acre；
(3) selenium-enriched konjac that the present invention cultivates, commodity taro is individually big, particular commodity taro 3kg or more；
(4) selenium-enriched konjac that the present invention cultivates, smooth, yield is high, and yield is up to 15000 jin or more；
(5) selenium-enriched konjac that the present invention cultivates, processing konjaku dry plate grade is excellent, reaches superfine；
(6) selenium-enriched konjac that the present invention cultivates, processing fine powder stain, yellow point are few, and viscosity is high；
(7) selenium-enriched konjac cultivated of the present invention, processing konjak series foods yield rate is high, and yield rate is up to 96%；
(8) selenium-enriched konjac that the present invention cultivates, pest and disease damage greatly reduce, and the disease incidence of pest and disease damage is reduced to 3% or less；
In order to solve the above technical problems, the technical solution of the present invention is as follows:
A kind of stereo cultivating method of selenium-enriched konjac, including stock up, dissolve potassium permanganate, impregnate sub- taro, peace kind, sprinkling selenium
Element.

5 times of ganoid konjaku taro diameter；
Level land: bud mouth 25 degree of inclinations to the south；Hillside fields: bud mouth 45 degree of inclinations on slope；
Then blinding, 12 centimeters of level land, tailo 10 centimeters, Schattenseite 8 centimeters, and so on, until finishing.
(6) sponge gourd is planted
After kind good konjaku of peace, by sponge gourd seed kind at 50 centimeters one plant of both sides spacing in the rows of every furrow；Through plantation growth after leaf,
Bar is all on steel pipe frame, first is that growth sponge gourd is killed two birds with one stone second is that being konjaku sunshade.
(7) joint steel pipe
Ground is drilled with micro hole, and be configured with water facilities, on steel pipe frame to steel pipe frame is taken at aerial 2 meters below steel pipe
Face is sponge gourd, and ready steel pipe is connected in the ground, keeps the sun off preparation in place for sponge gourd growth, konjaku.
(8) selenium element is sprayed
After the complete lamina of konjaku, selenium element plus 90 liters of water are sprayed in konjaku leaf on piece；By selenium member under light and effect
Element relatively moves to underground bulb and stores；
The selenium element is nanoscale, is the diameter (1/1000000000th meter) that 4 atoms string together.
(9) top dressing
7-9 month top dressing twice, and carries out field management.
(10) it harvests
In Frost's Descent October 23 in latter week, which receives, digs, and obtains selenium-rich commodity taro.
A kind of stereo cultivating method of the selenium-enriched konjac of embodiment 2
Cultural method described in embodiment 1 is taken, material preparation step is only changed, is changed are as follows:
Claim 350 kilograms of sub- taro, take steel pipe 350 with holes, 200 grams of selenium element, sponge gourd kind 750,250 kilograms of pulverized limestone,
650 grams of potassium permanganate, 1000 kilograms of water, mesh bag 25,1000 kilograms of organic fertilizer.
A kind of stereo cultivating method of the selenium-enriched konjac of embodiment 3
Cultural method described in embodiment 1 is taken, material preparation step is only changed, is changed are as follows:
Claim 450 kilograms of sub- taro, take steel pipe 280 with holes, 250 grams of selenium element, beans seed 700, pulverized limestone 350,000
Gram, 1000 grams of potassium permanganate, mesh bag 30,1200 kilograms of organic fertilizer.
The konjaku that the present invention cultivates, every kilogram of fresh taro 0.88-1.5mg/kg containing selenium element contain selenium in every kilogram of fine powder
3.08-5.25mg/kg；
Economic effect is between 20000 yuan to 35000 yuan per acre；

Selenium-enriched konjac of the present invention, the fine powder being processed into, stain, yellow point are few, and viscosity is high；Stain, Huang o'clock are 5% hereinafter, viscous
It spends up to more than 30000 centipoises (mpa.s)；
Selenium-enriched konjac of the present invention, processing konjak series foods yield rate are high；Yield rate is up to 96%.
Selenium-enriched konjac of the present invention, selenium-rich constituent content is high, plays the role of preventing disease to health after edible.
The unexpected effect of the present invention is that konjaku plantation pest and disease damage greatly reduces, and the disease incidence of pest and disease damage is reduced to 3%
Below.The disease incidence of common soft rot, southern blight is 25%-80%, and disease incidence reduces 96%.
Bright spot of the invention is: the local soil without selenium can also cultivation of selenium-rich konjaku, through Beijing Institute of Technology's biology point
It is reported from assay laboratory, every kilogram of fine powder contains 0.44 milligram of selenium, and adult needs selenium amount between 100---250 microgram daily, people
Service life and selenium element intake it is closely bound up, according to a large amount of data confirm, selenium-enriched area crowd occur cancer probability it is lower,
Otherwise it is higher.
A kind of stereo cultivating method of the selenium-enriched konjac of embodiment 4
The following steps are included:
