The not selection and its implantation methods of shattering cymose buckwheat rhizome kind
Technical field
The present invention relates to field of agricultural sciences, the selection of especially a kind of not shattering cymose buckwheat rhizome kind and its plantation side
Method.
Background technology
At present cultivation buckwheat type be general buck wheat (sweet tea buckwheat,Fagopyrum esculentumMoench)And bitter buckwheat
(Fagopyrum tataricumGartn.), all it is to harvest the annual herb plant of seed as the main purpose.It is given birth to
Phase is short, can harvest a season within general 2-4 months.But yield is relatively low.Usual general buck wheat yield is less than 80Kg/mu, and bitter buckwheat is low
In 150kg/mu.And every season is required for carrying out seed sowing, and cultivation cost is higher.
Perennial cymose buckwheat rhizome (Fagopyrum cymosumComplex, cymose buckwheat rhizome compound) it is nearest with cultivation buckwheat
The wild perennial buckwheat type of edge, can be divided into three types:Diploid F. megaspartanium (F. megaspartanium
QF.Chen), the wild buckwheat of diploid hair (F. pilusQF.Chen), allotetraploid cymose buckwheat rhizome (F. cymosum).These three
Morphologically some are approximate for type, therefore are usually collectively referred to as cymose buckwheat rhizome compound.Wherein hair open country buckwheat is mainly distributed on Tibet, and
And seed is small, culture and utility value is low.Tetraploid cymose buckwheat rhizome is not in great numbers enough, and seed is not full, although being not easy shattering, profit
It is low with being worth.F. megaspartanium is to be distributed most extensively, the big grain of seed, growth perennial type the most in great numbers, during rhizome is main
One of medicinal material usually only utilize its rhizome for pharmacy in production, does not utilize seed.And the nutritive value of its seed such as albumen
Matter content etc. is apparently higher than the cultivation buckwheat in production at present.But natural F. megaspartanium plant seed is particularly easy to threshing so that
The harvest of seed is very difficult.
Invention content
The purpose of the present invention is:A kind of selection and its implantation methods of not shattering cymose buckwheat rhizome kind are provided, it was both solved
It has determined the problem of reducing cultivation cost in agricultural production, has also solved the problems, such as F. megaspartanium seed shattering, to be agricultural production
On provide a completely new cereal crops and its seed production methods.
The invention is realized in this way:The not selection of shattering cymose buckwheat rhizome kind, cymose buckwheat rhizome wild resource are especially big
Wild buckwheat plant is distributed widely in wide geographic area such as Guizhou, Sichuan, Yunnan, Tibet, Guangxi, Guangdong, Hunan, lake on the south Chinese the Yellow River
North, Jiangsu, Zhejiang etc..And there is some difference in seed holding for the local population of separate sources.Shattering rate is selected to be less than 60%
Diploid Perennial F. megaspartanium is material, makes phase mutual cross between F. megaspartanium plant, it is small that progeny population can isolate shattering rate
In the high plant of 20%, plant type and single plant yield, these plant expand numerous i.e. acquisition not shattering cymose buckwheat rhizome kind through isolation.
The not implantation methods of shattering cymose buckwheat rhizome kind, the seed of above-mentioned not shattering cymose buckwheat rhizome kind is red by 100ppm
Mycin solution or 80ppm indolebutyric acids solution water-bath 30 minutes at 50 DEG C, then sowed by 30~50cm of spacing;Or it uses
Stalk was cut into the stem section saved with 2-3 by segment rapid propagation method before cymose buckwheat rhizome seedling stage or full-bloom stage, and biology is upper
Upward, 100ppm Gibberellins solutions or 80ppm indolebutyric acid solution are prepared, by clean gauze in 100ppm Gibberellins solutions or
It after 80ppm indolebutyric acid solution soaks, is laid on porcelain dish, 100ppm Gibberellins solutions or 80ppm indolebutyric acid solution will be passed through
It soaks overnight cymose buckwheat rhizome stem section to be put on above-mentioned gauze, then covers same moistening gauze, each cymose buckwheat rhizome stem section upper
It saves exposed, then covers moisturizing with film or disk cover, cymose buckwheat rhizome stem section bottom section can bear fibrous root after 3~5 days, and upper section is formed
Sprouting can transplant crop field after 6~8 days, require to pour root water when transplanting crop field, and keep 1 week moisture supply;During cultivation
Insect prevention diseases prevention can start to harvest in the maturity period after 90% or more fruit becomes ripe color.
Since this cymose buckwheat rhizome is to come from wild-type buckwheat, seed has very strong suspend mode, with seminal propagation, it is necessary to carry out
Vernalization is handled, and is found by experiment that 100ppm Gibberellins solutions (in the market 920) or 80ppm indolebutyric acids solution at 60 DEG C
Lower water-bath 30 minutes, can eliminate seed dormancy.
Many management, mainly insect prevention diseases prevention problem are not needed after field production generally.The Major Pests of cymose buckwheat rhizome are
Lepidopterous insects, Major Diseases are rust, the less generation of most cases.
Mechanized harvest may be used in harvest, can also use hand harvest, threshing is patted after drying.Gained seed can be with
Common Cultivation buckwheat equally shells into buckwheat rice or makes the derivative food of buckwheat rice.
The present invention carry out buckwheat seed production period be i.e. 1 year 1 year season harvest seed it is primary, can also receive within 1 year
Obtain 2 times, without sowing again since the 2nd year, perennial rhizome can self-growth until seed maturity and harvest, therefore plant
Training cost minimize, due to cymose buckwheat rhizome rhizome can only can be overwintering on the south the Yellow River, this method is more suited to each province on the south the Yellow River
Area needs to pay attention to when the area for being unable to safe overwintering uses and carries out antifreeze processing.
Due to the adoption of the above technical solution, the present invention reduces cultivation cost, selection and breeding not shattering using perennial characteristic
The breeding of type cymose buckwheat rhizome plant tames wild cymose buckwheat rhizome at raise crop, and carry out standardized cultivation and seed at new varieties
Production.The present invention is after first time cultivates, annual only to carry out simple Routine Management and harvest i.e. later without sowing again
It can get comparable seed production.Since shattering can not harvest seed, buckwheat rice, buckwheat powder and various buckwheat foods thus can be made;
The tender point that stalk can be won when seedling stage makees vegetables use;Its tender leaf and inflorescence can be fabricated to leaf tea, jasmine tea rich in Flavonoid substances;
Its root can make cymose buckwheat rhizome root medicine materical crude slice, and purposes is more and extensive.The special drought resisting of not shattering cymose buckwheat rhizome kind of the present invention is barren-resistant
