Abstract
The invention discloses a chrysanthemum cultivation method. According to the technical scheme of the invention, the chrysanthemum cultivation method sequentially comprises the following steps: (1) selecting and sterilizing explants; (2) preparing a culture medium; (3) cultivating the explants indoors; (4) transplanting outdoors; (5) pinching; (6) applying a fertilizer. The chrysanthemum cultivation method has the advantages of inhibiting bacterial virus from invading plants, resisting plant diseases and insect pests, enabling the chrysanthemum to grow quickly, increasing the survival rate and increasing economic benefit. In addition, auxin and cytokinin are increased in the culture medium, the mass concentration of the cytokinin is increased, formation of buds is benefited, the mass concentration of the auxin is increased, formation of roots is benefited, when the cytokinin and the auxin are in a certain balanced mass concentration, formation of the callus tissue is benefited.
Description
Technical field
The present invention relates to a kind of cultural method of chrysanthemum.
Background technology:
Chrysanthemum, is used as medicine with flower, is large conventional Chinese medicine, the adenine of glycosides containing chrysanthemum, choline, stachydrine, amino acid, robinin,
The compositions such as borneol level resacetophenone.The traditional Chinese medical science thinks its cold nature, bitter, dry.Nourish the liver to improve visual acuity, wind and heat dispersing the effects such as,
Cure mainly the diseases such as cold, fever, headache, tinnitus, red eye, swell pain, abscess of throat.
Chrysanthemum is liked gentle nice and cool weather and is faced south, slightly dry environment.Can be cold-resistant, flood afraid of water.It is raw in the environment for covering
Length is bad.Growth period requires that soil is slightly moistened, excessively arid, and plant branches out less, and development is slow, yields poorly, especially the nearly florescence,
Water shortage is unable to, is otherwise greatly reduced number of flowers.But excess moisture, then easily cause rotten dead seedling.Chrysanthemum happiness fertilizer, in loose fertilizer
The fertile, well-grown containing humus is abundant, in well-drained folder sandy soil, spends many yield high.Soil is with neutrality to subacidity or micro-
Alkalescence is suitable.All soil sticks the big plot of weight, hypsography low-lying, impeded drainage, saline alkali and should not cultivate.Avoid continuous cropping, exist year after year
Planted on same soil, pest and disease damage is more, and yield and quality significantly decline.Chrysanthemum belongs to short-day plant, and counterglow length is anti-
Should be sensitive, it is desirable to be no more than dailyThe illumination of hour, can just budding and bloom.
However, in the cultivation of chrysanthemum, the training initial stage is especially planted, it is most easily sick.It is subject to aleyrodid, aphid and the chrysanthemum tip
Worm, waits the harm of insect.So that its bulb occurs defect, wound can also ultimately result in kind of a scutellum rot by fungi, virus infection,
This is greatly lowered the survival rate of chrysanthemum, reduces economic benefit.
In addition, in existing implantation methods, all thinking that plantation chrysanthemum is not tight to soil requirement, will not make any to soil
Treatment, so in spite of illness, will can easily cause the chrysanthemum of plantation some common diseases, such as root rot, frost occur in itself due to soil
Mildew, brown spot etc., are also to be processed according to the method for conventional spray agricultural chemicals after there is disease pest, and environment is polluted, and
Soil texture can be also destroyed, food safety and sanitation standard is not met.Therefore, it should provide a kind of new technical scheme solution above-mentioned
Problem.
The content of the invention:
The invention aims to overcome the shortcomings of the above, there is provided one kind can suppress bacterial virus and invade plant, disease-resistant
Insect pest, the cultural method that can be mushroomed out chrysanthemum, increase a kind of chrysanthemum that survival rate is high, increase economic efficiency.
The purpose of the present invention is achieved through the following technical solutions,
A kind of cultural method of chrysanthemum, it is characterised in that comprise the following steps:
(1), the selection of explant and sterilizing:Stem apex, stem section and lateral bud from chrysanthemum as explant, in 5~August,
The chrysanthemum tender stem young sprout of robust growth is intercepted, the stem section and the lateral bud of health of 3cm after terminal bud, terminal bud is taken, is cleaned with clear water, then
With 60%-80% 25-35s of Ethanol Treatment, 0.5%-1.5% mercuric chloride processes 3-5min, and aseptic water washing 3-5 times is standby,
To stem apex and bud, need to carefully be peeled off under anatomical lens, and the tip of 0.5~1.5mm is cut with knife, be uprightly placed on culture medium,
Stem section is then directly placed on culture medium;
(2), culture medium processed:In parts by weight, its formula is made up of the culture medium following component:N15-P15-K17 1-2
Part, potassium chloride 1-1.5 parts, urea 1-1.5 parts, 1-1.5 parts of calcium nitrate type composite fertilizer N12.2-P0-K0-Ca24.5, EDDHA chelas
0.5-0.8 parts of iron is closed, each composition of the above halves and is made root media, and a certain amount of cell division is added in above-mentioned culture medium
Element and auxin, are configured to differential medium, and the basic element of cell division uses benzylaminopurine, 1-5mg/L, only in differential medium
Middle addition, auxin uses methyl α-naphthyl acetate, and consumption is 0.005-0.015mg/L in differential medium, is used in root media
It is 0.1-0.3mg/L to measure;
(3), indoor culture explant:Explant is initially positioned on differential medium and is grown, entered after differentiation is sprouted
Row squamous subculture, when further culture makes bud grow to 25-35mm, is transferred on root media, it is grown up to whole plant,
4-6d after inoculation explant, cultivates under half-light, awards the 12~16h of illumination of 1400~2000lx, cultivation temperature daily later
It is 23-26 DEG C;
(4), outdoor transplanting:Garden ground requires that the soil is porous, and draining is good, and soil will be made whole good ground through ploughing deeply thin rake
Into high ridge, the culture medium of seedling root is cleaned, is planted on seedbed, starting 2-4d will take cool canopy and spray water in time or spray,
Avoid intense light irradiation and ensure humidity high, illumination progressively can be suitably increased after 1~2d, water daily 1~2 time, summer high-temperature is poured
Water 2~3 times, and weed with a hoe in time and apply fertilizer, ensure seedling healthy growth;
(5) pinching:First time pinching is carried out when height of seedling is to 25cm, second pinching is carried out after 15~20d, then be spaced 15
~20d carries out third time pinching, after third time pinching, 200~300g calcium magnesium phosphate is sprayed to water 30 by every mu to plant blade face
~50kg;
(6) apply fertilizer:After buddingging, to plant foliage-spray foliar fertilizer once, every mu sprays 200~300g to every 8~10d every time
Calcium magnesium phosphate is to 30~50kg of water, and 150~200g potassium sulfates are to 20~50kg of water, when it is fickle in love scatter 2/3 when by harvest.
The present invention has advantages below compared with prior art:
1st, explant is sterilized repeatedly before sowing, is eliminated virus, the bacterium of female parent, improve surviving for transplanting
Rate, further suppress the germination and growth of germ spore, serve the effect for preventing germ from invading plant, reduce courses of infection
Chance.
2nd, auxin and the basic element of cell division are increased in the medium, and the mass concentration for improving the basic element of cell division is conducive to bud
Formation, improve auxin mass concentration, be conducive to the formation of root, both be in certain balance mass concentration when, be conducive to healing
The formation of injured tissue.
