A kind of little Amomum globosum loureiro high-yield cultivating method
Technical field
The present invention relates to a kind of cultivation method, particularly relate to a kind of little Amomum globosum loureiro high-yield cultivating method.
Background technology
Little Amomum globosum loureiro, Zingiber, Alpinia plants, blade wire lanceolar, top is point tool small cusp gradually, and base portion is gradually narrow, and except edge is by hair, two sides is all without hair; The tip of a leaf is blunt, keratin.Raceme is upright, and rhachis is by thin,tough silk hair; Bractlet Long Circle, calyx mitriform, corolla is without hair, and style is without hair; Ovary spheroidal, fruit spheroidal, florescence: the 4-6 month; The fruit phase: the 5-7 month.Produce China Guangdong, be born in thick forest, also there is distribution in Vietnam.The cultivation method of conventional ginger is that mid or late March starts to shine ginger, tired ginger, indoor vernalization, about about 20-30 days Furrow sowings in the time that bud grows to 1-1.5cm.Because little Amomum globosum loureiro germinates slowly early stage, to responsive to temperature, before sowing, need that time is long, main threads is loaded down with trivial details, the effort of taking a lot of work, need 25-30 days from being seeded into emerge, need 25-30 days from emerging to 5-6 sheet leaf, cause during this time idle land for up to 60-70 days, be enough to plant one batch of spring vegetables.And ginger seedling fearness high light, need field scaffolding to shade.Conventional method plantation ginger is time-consuming, effort, plants little careless guan usage amount large, and the field land occupation time is long, within 1 year, can only plant a season, is unfavorable for crops for rotation adjusting, and seedling-growing time is inconsistent, causes large seedling, weak seedling, is short of seedling.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of little Amomum globosum loureiro high-yield cultivating method, comprises the steps:
Tissue culture: collect seed and be chosen in continuous sunny and carry out after 7~8 days, before the production of hybrid seeds 2~3 days from soil Cheng Cong dig out the little Amomum globosum loureiro plant that needs to do kind, remove earth, and hanging upside down and drying 2~3 days in the place in room ventilation cool place; The tender shoots of the lateral bud on selection stem tuber or pumping is as explant material; Remove after blade and root system long on stem tuber, under running water, rinse earth well, and the tender shoots as explant material and old stem are cut open, and dab as the tender shoots of explant material and the surface of stem tuber with 0.5% the washing powder water that wet degreasing cotton dips in by weight, then under running water, rinse 10~20 minutes; On clean bench, remove as unnecessary blade and subtending leaf on the tender shoots of explant material; To on stem tuber, cut as the large lateral bud in the lateral bud of explant material, every explant material size is 1~2cm × 1~2cm size, every bottle of 3~4 block of material; With after 75% alcohol-pickled 30s, with aseptic water washing once, 0.1% mercuric chloride solution that reinjects carries out soaking disinfection 20~25 minutes, rinsing 5~6 times in sterile water, each 5~6 minutes; For subsequent use in rear immersion sterile water; To proceed on the induced bud medium just forming for induced bud every bottle of 1 bud, the wide-mouth vial that culture vessel is 250ml through the explant material of above-mentioned processing; Described induced bud medium is: MS+6-BA4.0~5.0mgL
