A kind of seed seedling-raising method of Wild jujube
Technical field
What the present invention relates to is a kind of seed seedling-raising method of Wild jujube.
Background technology
Wild jujube has another name called sour jujube, sour jujube, wild jujube, mountain jujube, Pueraria lobota pin etc., and is wild from ancient times in China.Fruit circular or oblateness, ellipse etc., pericarp redness or aubergine, pulp is thin, loose, sweet and sour.The nutritive value of wild jujube is very high, also has medical value.Wild jujube is as food, and is comparatively general.Like warm arid climate, drought-enduring, cold-resistant, alkaline-resisting.Fit the what sandstone soil cultivation in dry hillside, hills, mountain valley, Plain and roadside on the sunny side, should not be in low-lying waterlogged land plantation.
Advantages such as the breeding of wild jujube is mainly seminal propagation and division propagation, and the reproduction coefficient of division propagation is low, and seminal propagation has the reproduction coefficient height, and well developed root system, and it is vigorous to grow.Yet the seed of wild jujube is difficult for sprouting owing to there is dormancy; Prior art relates to (Li Xiuzhen etc., " wild jujube seed germination experiment ", " seed " of having of wild jujube seed germination; The 24th the 4th phase of volume; In April, 2005), yet it only relates to the influence to the wild jujube seed sprouting of storage time and temperature, and technology is single.
Summary of the invention
The present invention is directed to existing deficiency a kind of seed seedling-raising method of Wild jujube is provided.
The present invention realizes above-mentioned purpose through following method.
A kind of seed seedling-raising method of Wild jujube, this method comprises the following steps:
(1) choose seeds: remove seed, empty flat seed in spite of illness, seed is put moist shady and cool place, after-ripening 8-10 days, then seed is evenly tiled on the ground under equivalent environment, tiling thickness stirs once at 3-5cm every day;
(2) put into 600 times of liquid of thiophanate methyl after seed cleans with warm water and soaked 2-3 hour, use heteroauxin solution seed soaking 20-22 hour of 80mg/L again;
(3) cold plasma that utilizes atmospheric dielectric barrier discharge to generate is handled the wild jujube seed that obtains through step (2); The time of plasma treatment seed is 50-70 second; The power supply of said dielectric barrier discharge is a high-frequency and high-voltage power supply; Frequency range is 3kHz-5kHz, and voltage range is 5kV-7kV;
(4) with leaf mould, perlite, river sand and chicken manure by weight 4: 3: 2: 1 mixed preparation matrix, the tpn spray solution with 0.2% carries out sterilization processing on the matrix that stirs; To pass through step (3) then handles the seed obtain and broadcasts in the above-mentioned matrix; Line-spacing 19-21cm, spacing in the rows 3-5cm, and cover the sunshade net; Avoid receiving strong illumination, after 8-10 days, can germinate.
The time of said plasma treatment seed is 60 seconds, and the frequency range of said dielectric barrier discharge power supply is 4kHz, and voltage range is 6kV.
Beneficial effect:
1, the present invention fully utilizes after-ripening, growth regulator and plasma treatment etc. and breaks seed dormant technology; The technology of growth regulator and plasma treatment particularly; Comprise the growth regulator that adopted suitable concn and the time of proper frequency, voltage and processing, make the seedling from seed well developed root system that utilizes the Wild jujube that the present invention obtains, and growing way is good; Speed is fast, and survival rate is high.
2, prior to seeding matrix is carried out reasonable configuration; Wherein leaf mould and chicken manure are that seedling provides the sufficient nutrition supply; Perlite and river sand have then guaranteed the gas permeability of seedling matrix; For matrix has kept sufficient moisture, adopt above-mentioned setting simultaneously, finally improved the survival rate of Wild jujube seedling.
Embodiment
