Description
Technical field
The present invention relates to a kind of planting technology fields of medicinal and edible plant, in particular to a kind of polygonatum cyrtonema
Seedling breeding method.
Background technique
Rhizoma polygonati (Polygonatum sibiricum Red.) is the dry root of liliaceous plant, rhizoma polygonati or polygonatum cyrtonema
Stem integrates medicinal, edible, ornamental and cosmetic values.It is used as medicine with its rhizome, it is mild-natured, sweet in flavor, to nourish top grade, has and mend
Gas yin-nourishing, invigorating the spleen moistening lung, kidney-nourishing promote the production of body fluid, blood pressure lowering, hypoglycemic, reducing blood lipid and anti-aging and other effects.For treating taste void
Weak, fatigue and asthenia, dry deficiency of food, deficiency syndrome of the lung cough caused by dryness, asthenia of essence and blood, the diseases such as Heat Diabetes are very effective in cure for diabetes.
Jiangxi polygonatum cyrtonema shows the monopolizing characteristic of southern rhizoma polygonati, the counties and cities such as Yichuan, Ji'an is mainly distributed on, wherein with copper
Drum is more representative, and mostly based on wild acquisition, artificial planting technique is still immature.But it is yellow due to excessively excavation in recent years
Smart wild resource is fewer and fewer, endangered.Therefore, reinforce protection to genuine traditional Chinese medicine resource, breeding resistance, yield is excellent,
The high excellent variety of content is bred, and is engaged in artificial standardized planting and is seemed very necessary.
Currently, the plantation modes of reproduction of rhizoma polygonati mainly uses rhizomes breeding and seminal propagation.Wherein, due to using yellow
The rhizomes of essence, which carries out vegetative propagation, has the characteristics that the period is short, quick, and the breeding of most of farmer's rhizoma polygonatis is mainly logical
Cross vegetative propagation progress.But long-term vegetative propagation results in, and mixing for rhizoma polygonati plant causes kind provenance to degenerate, resistance is poor,
Plant virusization is serious, influences the yield and product quality of plantation, and rhizoma polygonati is cultivated with rhizome, and sowing quantity is big, breeding coefficient is low, limit
It has made and has been widely applied plantation.Rhizoma polygonati seed will undergo 2 winter dormancies that could emerge under natural conditions, if according to conventional work
The sub- seedling-raising technique management of species, then can hardly emerge.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, adapt to reality and need, provide a kind of polygonatum cyrtonema seedling
Mating system.
In order to achieve the object of the present invention, the technical solution adopted by the present invention are as follows:
A kind of polygonatum cyrtonema seedling breeding method, includes the following steps:
The first step, reserves seed for planting and seed growing: selecting wild polygonatum cyrtonema to be cultivated and strain of reserving seed for planting, polygonatum cyrtonema fruit
Fruit ball was seen that the outer formation of pericarp is blackish green and was picked in batches when turning black to the first ripe stage mid-August, and the fruit ball after picking is sealed
Kind of a decortication is washed in fermentation modulation after 6-12 days, obtain clean polygonatum cyrtonema seed；
Second step, seed low temperature Sand culture: the clean seed that the first step is obtained is placed in the wet sand sterilized, seed
It is mixed with wet sand with the mass ratio of 1:3~4,3-4 DEG C of low temperature, storage took out seed after 90--120 days；
Third step, seed reprocessing: passing through second step low temperature sand storage treated polygonatum cyrtonema seed plant hormone
Immersion treatment promotes it to root, then is soaked seed 6-8 hours with vernalization root-growing agent；
4th step, presprouting of seeds: treated that seed is layered on is lined with the constant incubator of wet filter paper by third step
In, it is arranged 38-42 DEG C of temperature in case, vernalization keeps bud long to 0.6~1cm；
5th step, seedbed setting: the hayashishita good permeability of negative degree 60%-70%, rich soil are covered in selection, or use temperature
Seedling in greenhouse is controlled, production moisture surface is 10- 30cm as seedbed, a length of 40-100cm of moisture surface, width, then high 20-40cm exists
The decomposed farmyard manure or organic fertilizer to ferment is applied by 1500kg--2000kg/ mus on seedbed；
Sowing: 6th step is broadcast the seed through the 4th step vernalization on the good seedbed of preparation and is covered using article broadcasting method
Upper pine needle is withered careless, and the shade that shading rate is 60%~70% is taken above seedbed；Meeting arid should water in time, keep wet
Profit；
Seedling management: 7th step throws off withered grass and keeps seedbed wet and shading, apply farmyard manure in conjunction with weeding or have after emergence
Machine fertilizer is with strong sprout.
In the first step, when harvested polygonatum cyrtonema fruit is blackish green xylocarp, ferment 12 days；Harvest polygonatum cyrtonema
When fruit is black mushy fruit, ferment 6 days.
In the 6th step, drilling, line-spacing 15cm are carried out after opening the ditch of 2cm depth on seedbed first, every row is spread
Fine earth is covered after the seed of 80~100 grain germinations, then is watered after covering pine needle or withered grass, is kept seedbed and withered grass drenched, is gone out in seedling
It is always maintained at seedbed before soil and during growth of seedling to moisten and shade, removes weeds and Shi Yici farmyard manure or organic fertilizer in time
Strong sprout.
In the second step, the humidity of wet sand is 30--40%, i.e., the mass ratio of sand and water is 100:30-40, and
Wet sand one hold it is agglomerating, loose one's grip i.e. dissipate.
In the third step, the plant hormone is gibberellin or ethylene.
A length of 50cm of the moisture surface, width 20cm, high 30cm.
The beneficial effects of the present invention are:
1. method for culturing seedlings is simple, at low cost, the needs of rhizoma polygonati large area standardized planting nursery can be met, reduced wild more
The excavation of flower rhizoma polygonati, improves the income of farmer；
2. polygonatum cyrtonema seed is wherein carried out low temperature Sand culture by second step, it is ensured that polygonatum cyrtonema seed completes life
After-ripening is managed, while can be shortened seed dormancy phase；Seed treatment and vernalization again can improve the germination percentage and emergence rate of seed, shorten
Seedling raise period；Seed sprouting and seedling management are convenient in the setting in seedbed, can improve the survival rate of seedling；
3. can be realized the protection and sustainable use of polygonatum cyrtonema wild resource.
