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 the method at sowing or plantation pre-treatment seed.
Background technology
Oriental hybrid lily is the top grade flower that is subjected to the market favor most; yet; the lily seed under field conditions (factors) after planting; can be in one month the balling sprouting except 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 to can sprout through the time more than 1 year; can seed take place in the long seed germination phase like this goes rotten; reduce seed germination rate greatly; the seedling that sprouts is irregular, puts forth slowly, and the so long seed germination phase; the scale of lily flower breeding industry will seriously be restricted; industrialized development is difficult to satisfy market to the demand of 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 illustrate 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 under normal temperature 1.5～3 months, handled under-1～4 ℃ low temperature 1.5～3 months, get the balling seed, 30～70 days ability and sprout neatly, the time is longer relatively.
Summary of the invention
The invention provides a kind of alternating temperature processing method that can shorten the oriental hybrid lily seed germination time, 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 by 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 is with 350～450 times of 65～75% thiophanate methyls dilutions+with 350～450 times of 45～55% captans dilutions+make 350～450 times of hectogram dilutions+with the mother liquor of 450～550 times of 35～45% pirimiphos-methyls dilutions with 20～30%, 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 at the thick hypothallus of packing case bottom shop 3～5cm, spread one deck oriental hybrid lily seed then, covered seed with matrix, spread one deck seed in matrix again, 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 branch is installed 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 finished, 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, hardening: the constant temperature storehouse temperature is upgraded to 14～16 ℃, be under 50～60% the condition in humidity, hardening 1-2 week, treat that blade launches fully, move into and continue in the booth to cultivate, and every morning, afternoon are to each ventilation of booth once, and time of exchanging gas is 20～40 minutes/time, 1～2 week back 95～100% seedling survive.
Preferably, earlier at the thick hypothallus of packing case bottom shop 4cm, spread one deck oriental hybrid lily seed then among the described step C, covered seed with matrix, spread one deck seed in matrix again, 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 described step D branch installed 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 finished in the described 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.
Described step G is upgraded to 14～15 ℃ with the constant temperature storehouse temperature, be under 50～60% the condition in humidity, hardening 1-2 week, treat that blade launches fully, move into and continue in the booth to cultivate, and every morning, afternoon are to each ventilation of booth once, and time of exchanging gas is 30 minutes/time, 1～2 week back 95～100% seedling survive.
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 hardening 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.
