The rapid propagation method of chicory seed is got over Winter Solstice second year by the vegetative bud cuttage field production that autumn wins witloof plant and is adopted
Sowing.
The method of above-mentioned quick breeding chicory seed is realized by step in detail below:
(1) cuttage root-taking: the vegetative bud sprouted at rootstock is won in autumn and carries out cuttage and cultivates to taking root；
(2) it transplants: the cuttage seeding taken root being transplanted to field, carries out Routine Management nurturing staff；
(3) branch: field strong sprout open field soil is harvested, until 22-32 days harvests are with inflorescence after second year full blossom mid-term
Branch；
(4) it screens seed: the branch of harvest is set into storage of taking shelter from rain at shady and cool ventilation, rubbing flower after branch is withered dry
Sequence screens full seed.
Wherein vegetative bud selected from the character of spring sowing or last year autumn sowing for the year, plant by excellent, robust growth witloof in step (1)
Strain；Most preferably winning the time is mid-September to late October.
Branch Best harvest time in step (3) with inflorescence is full blossom mid-term (so-called full blossom mid-term are as follows: enter full-bloom stage
The middle time point significantly reduced to flower amount) it harvests within the 22nd day later, which can be according to the weather condition of current year in front and back
It is chosen in two days.
Further, cutting medium in step (1) uses: vermiculite 5L, coco bran 10L, the decomposed muck 0.5kg dried,
Bone meal 0.1kg.
The present invention has the advantage that compared with prior art
The present invention is by carrying out Autumn Cutting breeding to witloof plant, and overwintering rear second year harvests seed, and harvest is for the year
Autumn sowing can be carried out, propagation method is simple, and the seed harvested, without dormant period, harvest current year summer can autumn sowing production.
The present invention utilizes the stronger meristematic capacity of witloof, and the vegetative bud that sprouting can be repeatedly won from the rootstock of maternal plant carries out
Cuttage, a maternal plant can cultivate multiple intact plants, so that expanding propagation coefficient, breeds a large amount of seeds；And mother can be effectively retained
The genetic background of strain so that the seed of different year production has good genetic stability, and make between offspring individuals character compared with
It is consistent.
The present invention utilizes the strong antifreeze properties of witloof, healthy and strong plant In Nanjing can safe overwintering, and normal growth
Development, spring bolting are bloomed, are spent rear solid.
The branch that the present invention harvests after full-bloom stage prior to take shelter from rain at shady and cool ventilation store a period of time after handle again,
Latter stage of ripening can be extended, it is sufficiently mature to be conducive to more seed, while be avoided that again because of mature seed shedding or being sent out on inflorescence
Bud and cause yield reduce and quality decline.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.
Influence of the different harvest times of embodiment 1 to seed production and quality
It on September 22nd, 2017, selects that character is excellent, witloof plant of robust growth, wins the nutrition sprouted at its rootstock
Bud (no less than three pieces adult leaf is advisable) carries out cuttage, cutting medium formula are as follows: vermiculite 5L, coco bran 10L, the decomposed muck dried
0.5kg, bone meal 0.1kg.Observation on October 23, cuttage bud are all taken root, take 12 plants to be transplanted to field.All transplanted seedlings exist
It is survived in 10d, well-grown and safe overwintering, starts bolting by the end of March, beginning May 17~21 flower entered and contains on May 22~24
At the florescence, June 19, the amount of blooming significantly reduced later.It is adopted respectively on June 27th, 2018, July 7, July 16 and August 9th
Receive, 3 plants every time, the plant of harvesting (taking the branch part with inflorescence on the ground) is stored in take shelter from rain, shady and cool and ventilation, work as branch
It withers and rubs inflorescence after sufficiently drying, screen full seed.Weigh the weight of each strain seed；Every plant of seed is divided into 3 parts, every part
50 are taken to make germination test at random, 3d counts germination percentage.The plant of different time harvesting, the single plant yield and germination percentage of seed
As shown in table 1.
Its yield of chicory seed and germination percentage of 1 different time of table harvesting
Seen from table 1, the seed of June 27 and harvesting on July 7, single plant yield and its germination percentage are above July 16
With the seed of harvesting in August 9th.12 single plants of this test transplanting entered full-bloom stage May 22~24, and June 19, flower amount was bright
It is aobvious to reduce, the middle time point (June 5) in (June 19) is significantly reduced to enter full-bloom stage (May 22) to flower amount as full blossom
Mid-term, experiments have shown that, 22-32d or so harvests seed after full blossom mid-term, there is high yield and quality, too late harvesting yield and product
Matter is substantially reduced.And there is maximum output and quality with seed obtained by the plant of harvesting in the 22nd day after full blossom mid-term, specific
Field can be carried out according to the nearest time at the weather condition selected distance time point of current year when harvesting to collect.
2 different time of embodiment wins influence of the vegetative bud cuttage to chicory seed yield
It chooses that character is excellent, witloof plant of robust growth respectively at September in 2017 22 days, October 24, wins its root
The vegetative bud sprouted at neck carries out cuttage, respectively takes 3 plants to be transplanted to respectively on October 23rd, 2017, November 23 after it is taken root
Field harvests on June 27th, 2018, during which investigates to all plant, and morphological index, growing process and seed produce
Amount is as shown in table 2.
Morphological index, growing process and the seed production of 2 the formed plant of different time cuttage witloof vegetative bud of table
Note:*Plant diameter (cm) after overwintering: for the diameter of witloof rosette plants before bolting after overwintering, in April, 2018
It measures within 2nd.**Aerial part fresh weight (g/ plants), level-one branch amount (a/strain), seed production (g/ plants): being June 27 in 2018
It is measured when day plant harvest.
As can be seen from Table 2, compared with the plant that September cuttage on the 22nd is formed, the plant of cuttage on the 24th in October, before the early flowering season
Growth potential is weaker and breeding time is slower, but breeding time indifference after the early flowering season；Although aerial part fresh weight and level-one branch amount
It is lower, but seed production is not reduced.Test result shows September 22 days to can win vegetative bud skewer during October 24
