Abstract
The present invention provides a seedling-cultivating method of Iphigenia indica Kunth seed. It is characterized by that said method includes the following steps: (1, storing the seed for 5-6 months at 2-5deg.C, soaking the seed for 18-24hr in whater whose pH value is 6-7, then under the condition of that temperature is 25-28deg.C, illumination is 2000-3000lx and illumination time is 10-12hr every day accelerating germination; (2), uniformly mixing the treated seed and humectous soil according to the volume ratio of 1:3, then scattering, after scattering covering with fine soil layer whose thickness is 1-2min, then covering with a layer of loose hair whose thickness is 2-3cm, promptly spraying water and building plastic hot house; and (3), retaining soil humidity for two months before cultivating seedling, making the soil humidity be 80-85% and making its temperature be 15-30deg.C. Said invention can make the emergence time be shortened to 40-50 days and the rate of emergence can be up to above 95%.
Description
Technical field
The present invention relates to a kind of Iphigenia indica kunth et benth seed grow seedling method.
Background technology
Iphigenia indica (Iphigenia indica Kunth) is the perennial herbelet of Liliaceae, is distributed in Tibet, Sichuan, middle part, Yunnan and the northwestward.Be used as medicine with bulb, be mainly used in gout and tumor treatment.Iphigenia indica is the main Chinese medicinal materials source of domestic extraction, separation and preparation colchicin and analog thereof, and along with the continuous expansion of colchicin market demand, wild going to wreck property of iphigenia indica is excavated, and is endangered.In recent years, at Yunnan Province's Lijing municipalization artificial cultivation, mainly be that the underground bulb of excavating wild iphigenia indica is planted, because 95% iphigenia indica bulb has the characteristic that substitutes growth, make the bulb sowing yield poorly.Seed is best propagating materials, but the seed dormancy phase is long, is difficult to breaking dormancy under field conditions (factors), and the kind shell is hard, and permeability is poor, and iphigenia indica still is a kind of happiness light thermophilous in addition, and is extremely strict to temperature and illumination condition requirement when growing seedlings.Seed breeding seedling-growing time under field conditions (factors) reaches 2-3 month, emergence rate less than 20%, and production cost strengthens.
Summary of the invention
The objective of the invention is to solve the iphigenia indica problem of seed seedling-raising existence under field conditions (factors), the Iphigenia indica kunth et benth seed grow seedling method that a kind of seedling-growing time is short, emergence rate is high is provided.
The present invention is achieved in that Iphigenia indica kunth et benth seed grow seedling method comprises seed treatment, sowing, seedling management step:
1, seed treatment
Seed is at 2-5 ℃ of following storage after 5-6 month, with the water logging bubble of pH=6-7 after 18-24 hour, is vernalization under the condition of 10-12 hour every day at temperature 25-28 ℃, illumination 2000-3000lx, light application time again, till beginning to show money or valuables one carries unintentionally to the 25-30% seed.
2, sowing
With the seed handled well and moist fine earth by 1: the volume ratio of 3-4 broadcasts sowing after evenly mixing.Broadcast sowing the thick fine earth of bonnet 1-2mm, cover the thick pine tag of 2-3cm again, timely water spray will guarantee that the intensity of illumination of seed is 1000-1500lx after cover native and pine tag.In order better to improve temperature and to keep soil moisture, put up plastic canopy.
3, seedling management
The first two months of growing seedlings keeps soil moisture at 80-85%, between temperature 15-30 ℃, throws off the thick pine tag of 1-2cm after one month, throws off plastic canopy after two months gradually, the weeding of in good time watering.Plant falls behind the seedling, throws off 90% pine tag, and ridging 2-4cm covers thick pine tag or the black mulch film of 3-5cm.When beginning to emerge, iphigenia indica threw off half thick pine tag or black mulch film in 1 year.
The present invention can make the Iphigenia indica kunth et benth seed grow seedling seedling-growing time shorten to 40-50 days, and emergence rate is up to more than 95%.Can shorten seedling-growing time, improve emergence rate, reduce production costs, can produce huge economic benefit.
Embodiment
1, seed treatment
Select for use the wild iphigenia indica (Iphigenia indica Kunth) of Lijing drum-shaped stone blocks locality to make provenance, the wild iphigenia indica strong stress resistance in this place, and Colchicine Content height.Seed is collected in life in 4 years and above good, healthy plant thereof the first year, and thousand kernel weight is greater than 2.2g.In order to break seed dormancy, with the seed Ex-all impurity of gathering then, be positioned in 2-5 ℃ the refrigerator storage after wrapping with brown paper 5-6 month, each week of storage period is stirred once.Because the kind shell of Iphigenia indica kunth et benth seed grow is hard, permeability is poor, so steeped 18-24 hour softening kind of a shell with the water logging of pH=6-7 through the seed of cryopreservation.Iphigenia indica is a kind of happiness light and thermophilous, under dark and cryogenic conditions, can not germinate, therefore at last be vernalization under the condition of 10-12 hour every day at temperature 25-28 ℃, illumination 2000-3000lx, light application time, till beginning to show money or valuables one carries unintentionally to the 25-30% seed, germination time is generally at 16-19 days.
2, sowing
Select the sand loam that soil layer is deep, loose, water penetration is good, the pH of soil is 6-7, and the content of organic matter is 3-5%.Use sufficient base fertilizer, whole ground, whole good field top-pour is permeable, puts in order once more and carefully rakes.Broadcast sowing after the seed handled well and moist fine earth are evenly mixed by 1: 3 volume ratio mid-April.Broadcast sowing the thick fine earth of bonnet 1-2mm, cover the thick pine tag of 2-3cm again, timely water spray will guarantee that the intensity of illumination of seed is 1000-1500lx after cover native and pine tag.In order better to improve temperature and to keep soil moisture, put up plastic canopy.
3, seedling management
The first two months of growing seedlings keeps soil moisture at 80-85%, between temperature 15-30 ℃, after two months, is not very high to the requirement of soil moisture and temperature, can grow under the natural conditions.60% seed sprouting after one month is thrown off the thick pine tag of 1-2cm, and weeding is once thrown off plastic canopy after two months gradually, is beneficial to strong sprout.The weeding of in good time watering after November, plant fell seedling, is thrown off 90% pine tag, and ridging 2-4cm covers thick pine tag or the black mulch film of 3-5cm.When beginning to emerge, iphigenia indica threw off half thick pine tag or mulch film in 1 year.Sow that the emergence rate of seed reaches more than 90% after 40-50 days, because the Iphigenia indica Kunth et Benth seed has the characteristic of sprouting for many years, also had 5% seed sprouting in 1 year, total emergence rate of seed can reach more than 95% after 2 years.
