The oriental lily seed variable-temperature treatment method has the advantages that the defects existing in the prior art are overcome, the rapid germination of seeds is promoted, the germination vigor and the germination rate of oriental lily seeds are improved, the germination tidiness of the seeds is improved, the step of seed sterilization is omitted, a better effect can be reached by adopting simple operations and the method is suitable for large-scale ball acceleration and germination of oriental lily hybrid seeds.
Description
Technical field
The present invention relates to field of planting, relate in particular to method at sowing or plantation pre-treatment seed.
Background technology
Oriental hybrid lily is the top grade flower that receives the market favor most, yet the lily seed under field conditions (factors) after planting; Can be in one month the balling sprouting except that the part seed of cone drums lily seed and Asia lily, the seed of oriental hybrid lily seed and oriental hybrid lily and the hybridization of other hybrids system then will can be sprouted through the time more than 1 year; Can seed take place in the long seed germination phase like this and go rotten, reduce seed germination rate greatly, the seedling of sprouting is irregular; Put forth slowly; And the so long seed germination phase, with the scale that seriously restricts lily flower breeding industry, industrialized development, be difficult to satisfy the demand of market to the lily new varieties.
At present, it is generally acknowledged that low temperature treatment can break the oriental hybrid lily seed dormancy, shorten the seed germination time, improve germination rate.But it is long that the employing low temperature method is broken the time of oriental hybrid lily seed dormancy needs, and explain that the test data of its concrete effect lacks.
Be that the Chinese patent of CN201110112790.9 discloses a kind of method that promotes the lily seed germination just like the patent No. again.Be that treated lily seed was handled 1.5～3 months under normal temperature, handled 1.5～3 months down in-1～4 ℃ low temperature, get the balling seed, it is neat ability sprouting in 30～70 days, and the time is longer relatively.
Summary of the invention
The present invention provides a kind of alternating temperature processing method that can shorten the oriental hybrid lily seed germination time, and this method can improve the oriental hybrid lily seed germination rate, and it is normal that seed growth is grown, and effectively shortens the crossbreeding cycle.
The present invention realizes through following technical proposal: the method that a kind of oriental hybrid lily seed alternating temperature is handled may further comprise the steps:
A, seed selection: choose the oriental hybrid lily hybrid seed that embryonic development enriches.
B, matrix treatments: preparation 65～75% thiophanate methyls 350～450 times+45～55% captans 350～450 times+20～30% make the mother liquor of 450～550 times of hectogram 350～450 times+35～45% pirimiphos-methyls; Getting this mother liquor admixes in the peat; Fully mix; Making the peat water content is 50～60%, and hand is firmly held not expressed water and is advisable.
C, packing: earlier, spread one deck oriental hybrid lily seed then, covered seed, on matrix, spread one deck seed again with matrix at the thick hypothallus of packing case bottom shop 3～5cm, spreading successively, 4～7cm place is paved with matrix to the packing case top.
D, room temperature treatment: it is in 20～25 ℃ the constant heat storage, to be 70～80% in humidity that the oriental hybrid lily seed that installs branch moves into temperature, and time of exchanging gas is each 20～40 minutes, respectively changes once in every morning, afternoon under the condition of gas, handles for 7～8 weeks; Then the constant heat storage temperature being reduced to 15～17 ℃, is 50～60% in humidity, and time of exchanging gas is each 20～40 minutes, under twice the condition of taking a breath every day, handles for 2～4 weeks; At last the constant heat storage temperature being upgraded to 20～25 ℃, is 70～80% in humidity, and time of exchanging gas is each 20～40 minutes, under twice the condition of taking a breath every day, handles for 2～3 weeks.
E, low temperature treatment: after room temperature treatment is accomplished, the constant temperature storehouse temperature being reduced to 2～5 ℃, is 50～60% in humidity, and time of exchanging gas is each 20～40 minutes, and under twice the condition of taking a breath every day, constant temperature was handled 3～4 months.
F, detection: behind the oriental hybrid lily seed sprouting, record its germination rate and reach 95～98%.
G, refining seedling: the constant temperature storehouse temperature is upgraded to 14～16 ℃; Be under 50～60% the condition, in refining seedling 1-2 week, to treat that blade launches fully in humidity; Move into and continue in the booth to cultivate; And every morning, afternoon are to each ventilation of booth once, time of exchanging gas be 20～40 minutes/inferior, 1～2 week back 95～100% seedling become to live.
Preferably, earlier at the thick hypothallus of packing case bottom shop 4cm, spread one deck oriental hybrid lily seed then among the said step C, covered seed, on matrix, spread one deck seed again with matrix, spreading successively, 4～6cm place is paved with matrix to the packing case top.
It is in 22～23 ℃ the constant heat storage, to be 70～80% in humidity that the oriental hybrid lily seed that among the said step D installs branch moves into temperature, and time of exchanging gas is each 30 minutes, respectively changes once in every morning, afternoon under the condition of gas, handles for 7～8 weeks; Then the constant heat storage temperature being reduced to 15～17 ℃, is 50～60% in humidity, and time of exchanging gas is each 30 minutes, under twice the condition of taking a breath every day, handles for 2～4 weeks; At last the constant heat storage temperature being upgraded to 22～23 ℃, is 70～80% in humidity, and time of exchanging gas is each 30 minutes, under twice the condition of taking a breath every day, handles for 2～3 weeks.
After room temperature treatment is accomplished in the said step e, the constant temperature storehouse temperature being reduced to 2～5 ℃, is 50～60% in humidity, and time of exchanging gas is each 30 minutes, and under twice the condition of taking a breath every day, constant temperature was handled 3～4 months.
Said step G is upgraded to 14～15 ℃ with the constant temperature storehouse temperature; Be under 50～60% the condition, in refining seedling 1-2 week, to treat that blade launches fully in humidity; Move into and continue in the booth to cultivate; And every morning, afternoon are to each ventilation of booth once, time of exchanging gas be 30 minutes/inferior, 1～2 week back 95～100% seedling become to live.
Beneficial effect:
1. the present invention carries out the alternating temperature processing and breaks oriental hybrid lily Seed Dormancy characteristic, promotes seed quick-speed germination, and it is normal that seed growth is grown, and effectively shortens breeding cycle.
2. after the present invention chooses seed, need not to disinfect just and can directly use the peat embedding, greatly reduce cost when simplifying the operation step.
3. the room temperature treatment of this method adopts 20～25 ℃ Temperature Treatment earlier, adopts 15～17 ℃ of Temperature Treatment again, and clove is fully expanded, and adopts 20～25 ℃ Temperature Treatment again, greatly promotes to urge ball to sprout.
4. 1～2 week of this method refining seedling just can sprout neatly, and than the oriental hybrid lily method for treating seeds of routine fast 23～60 days, accelerated oriental hybrid lily breeding speed greatly, and promotion puts forth, improve its germination regularity.
