Description

A kind of Huanghua Pear seed seedling-raising method
Technical field
The present invention relates to vegetable seeds seedling-raising technique field, and in particular to a kind of Huanghua Pear seed seedling-raising method.
Background technology
Huanghua Pear scientific name is dalbergia wood, is Papilionaceae Dalbergia arbor, its timber is of fine quality, and sapwood is faint yellow, and matter is slightly loose, Heartwood bronzing, heavily fortified point weight, texture is fine and close, is first-class furniture good timber；It is savory, spices can be made；Root heartwood name dalbergia wood, for medicine With；For good analgestic, and knife wound bleeding is controlled, therefore, it has higher medical value and economic value.
The skewer of chrysanthemum pear tree, which broadcasts breeding, needs a large amount of good basic seedlings, and method for culturing seedlings is cumbersome, of high cost and be easy to cause Virus accumulation, influences the hereditary capacity of excellent seedling；Propagation by grafiting and division propagation survival rate are low, and it is low that branch skewer broadcasts rooting rate, group Knit culture to be difficult to take root, slow-growing, growing-seedling period length.The needs for being difficult to meet good seed using traditional seedling raising method.
The content of the invention
For problems of the prior art, the present invention provides a kind of Huanghua Pear seed seedling-raising method, this kind of nursery Method is simple and practicable, and low production cost, growing-seedling period is short, and the seedling disease resistance grown is strong, and survival rate is high, rooting rate It hurry up, growth is rapid, neat healthy and strong, improves ecological benefits and economic benefit.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of Huanghua Pear seed seedling-raising method, follows the steps below：
(1) seed selection disinfection：In the Huanghua Pear Fruit maturity period, the fruit of full maturity and no disease and pests harm is selected from excellent maternal plant Real, the seed that full seed is gathered after being dried is cleaned, dried, disinfected；
(2) distillate is soaked seed：Seed after drying in the shade is soaked in 4-6h in 45 DEG C -55 DEG C of rose wood distillate；
(3) corona treatment：Utilize the Huang of the cold plasma processing step (2) of atmospheric dielectric barrier discharge generation Flower pears seed, the time of corona treatment seed are set as 65-85s；
(4) vernalization is handled：Huanghua Pear seed obtained by step (3) is wrapped up with wet towel, in temperature for 22 DEG C -26 DEG C, Vernalization sprays eupatorium adenophorum extracting solution and keeps towel to germination under the conditions of intensity of illumination is 1500~2500Lx during vernalization Moistening；
(5) broadcast sowing and seedling management：Huanghua Pear seed broadcasting after germination is poured into cultivation matrix permeable, broadcast sowing depth For 1.5-2.5cm, cultivation matrix thickness is 10-12cm, is sought afterwards every 2-4 days toward one time of nutrition liquid is sprayed in cultivation matrix Nutrient solution dosage is 4-6g/m2, and soil moisture is kept between 65%-75%, growing temperatures are 20 DEG C -30 DEG C, are separately being cultivated Matrix upper strata sprinkles quick lime, and quick lime dosage is 8-12g/m2；
(6) transplanting and nursery stock management：Start to transplant when Huanghua Pear seedling is grown to 35-45cm in step (5), the choosing of transplanting ground Select sunny, physical features is not flooded, irrigation and drainage convenience, short texture, soil fertility are fertile, soil depth 70-120cm sandy loam, Live Huanghua Pear seedling is to dig to plant, and earthing up, it is permeable to be poured after being compacted in root position, and every plant of seedling applies the organic of 100-200g Fertilizer, irrigated a water every 30-40 days afterwards, and combined prevention pest and disease damage sprinkling potassium dihydrogen phosphate.
Further, in step (1), above-mentioned disinfection is that the Huanghua Pear seed after drying is placed in 42 DEG C -48 DEG C Soak seed 8-12h in magnetized water, further takes out and is filtered dry the surface of the seed moisture, is then placed on the sodium hypochlorite that volumetric concentration is 15% In disinfect 20-30min, take out with aseptic water washing 3-5 times, it is spare after the surface of the seed moisture that dries in the shade；
Further, in step (2), above-mentioned rose wood distillate is made by following steps：In 0.05-2.5MPa Under the conditions of absolute pressure, Huanghua Pear timber is placed in closed environment, is conducted heat using steam or inert gas as medium to timber, it is cold The material that solidifying recovered temperature is evaporated at 160 DEG C -320 DEG C, obtains rose wood distillate after liquefaction.
Preferably, above-mentioned inert gas uses nitrogen or argon gas.
Further, in step (3), the power supply of above-mentioned dielectric barrier discharge is high-frequency and high-voltage power supply, and frequency range is 2.5kHz-3.5kHz, voltage range 3.5kV-4.5kV.
Further, in step (4), above-mentioned eupatorium adenophorum extracting solution is made by following steps：Take appropriate purple stem The ethanol that it is 95% relative to the determining alcohol of 6~8 times of cauline leaf quality that Herba Lycopi's cauline leaf, which is added, is heated to reflux 1~2h, filtering to filter Filter residue, is added the ethanol for being 95% relative to the determining alcohol of 4~6 times of filter residue quality, is heated to reflux 2~3h, filters by slag again Removal of impurities, merges filtered fluid, removes ethanol, is concentrated into after the 1/4-1/3 of original volume to obtain the final product.
Preferably, in step (5), above-mentioned cultivation matrix includes diatomite, silkworm excrement, perlite and vermiculite, each component Between mass ratio be 2:1:1:1.
Preferably, in step (5), above-mentioned nutrient solution includes following component by weight：Eupatorium adenophorum extracting solution 8-10 parts, 6-8 parts of rose wood distillate, 1-2 parts of fulvic acid, 4-8 parts of brassin, 0.3-0.5 parts of copper sulphate, calcium superphosphate 0.1- 1-2 parts of 0.3 part, 0.2-0.4 parts of monoammonium phosphate, 0.1-0.3 parts of ferrous sulfate and Bravo.
The present invention has following beneficial effect：The Huanghua Pear seed seedling-raising method of the present invention is simple and practicable, production cost It is cheap, seed seedling-raising initial stage using bask seeds, soak seed, the technology such as corona treatment and vernalization breaks seed dormancy, make seed fast Speed germination, accelerates seed and sprouts, improve seeding ratio, shorten seedling-growing time, enhance the Anti-bacterium ability of seed, environment is fitted Should be able to power it is strong, emergence is neat healthy and strong；Afterwards again by scientifically and rationally broadcasting sowing management and transplanting and management so that Huanghua Pear seedling gives birth to Root speed is fast, and well developed root system, sapling be healthy and strong, the virus-free plague of insects, survival rate are high, and growth of seedling is fast, and nursery stock year increment is big, significantly Shorten growing-seedling period, improve ecological benefits and economic benefit；
(1) the Huanghua Pear seed after disinfection is carried out at seed soaking using rose wood distillate in method for culturing seedlings of the invention Reason, this kind of rose wood distillate green natural, there is excellent growth regulating to act on Huanghua Pear seed, can effectively improve Seed physiology function, promotes the after-ripening of seed and improves the activity of enzyme, improve plant water use efficiency and cell membrane Stability, enhances early warning and respond of the seed to adverse environment, and then Huanghua Pear seedling strain drought resisting, salt resistance, cold-resistant And the purpose of disease and insect resistance；
(2) the eupatorium adenophorum extracting solution natural green nonhazardous used in vernalization processing, can not only play antibiotic and sterilizing Effect, moreover it is possible to as plant growth regulator, seed germination exciting agent, promotes seed fast germination, grows vigorously；
