Abstract
The invention provides a method for cutting and propagating creeping stems of primula pseudodenticulata pax view. The method comprises the following steps of: cutting the creeping stems picked from the primula pseudodenticulata pax view plant into 1/3 leaves, cutting the young seedlings with the stem length of 5 to 6cm into the matrix with the thickness of 8 to 10cm and the following mass ratio: garden soil: humus soil: perlite is equal to 1:1 to 2:1 to 2, the cutting depth is controlled to 3 to 4cm, the cutting density is better to non-overlap the leaves of the cutting young seedlings, the matrix is watered thoroughly after cottage, plastic films and sunshade screens are used for covering, management after cottage is carried out according to the conventional manner, and the hardening off of the seedlings can be carried out after 20 to 25 days. The method not only has easy seedling cutting and large amount, but also has easy cuttage, fast propagating speed, obtains strong hardened-off seedlings with strong insect prevention and disease resistance, has the survival rate of 60 to 70 percent after transplantation, is beneficial to industrial development of the primula pseudodenticulata pax view and has wide market prospect.
Description
Technical field
The present invention relates to a kind of method for cutting and propagating creeping stems of primula pseudodenticulata pax view, belong to field of plant growing technology.
Background technology
Yunnan sea daffodil (Primula pseudodenticulata Pax) is the perennial herb of Primulaceae primula, and complete stool does not have hair.Root-like stock is extremely short, can bear stolon from the top.Leaf is many, falls lanceolar to narrow obovate square circle, long 3～10cm, and wide 0.5～2.5cm, the high 6～35cm of scape, the nearly head of umbel is spent more, and the corolla pink is to purplish blue color, February in December at florescence to next year, fruit 3～April of phase.Sea, Yunnan daffodil is liked well-drained soil; Happiness light has certain anti-shady ability; The happiness moist environment.The daffodil plant root prosperity of sea, Yunnan, growing way is strong, and is strong to the adaptability of environment, and do not need other any control measures vegetative period except that daily rich water quality management, manage extremely extensive.
Yunnan sea daffodil plant height is moderate, and strain shape is delicate and the leaf look gratifying, again the four seasons evergreen, be the good material of ornamental foliage plant.During Yunnan sea daffodil plant blossom, except that the main scape of a comparatively thick shape, around main scape, can also bear the little scape of racemosus, inflorescence is closely spherical, and each inflorescence and given birth to tens of of Xiao Hua, basketball piece piece when blooming, sight is high, and the florescence is long, and its florescence and China match traditional festival-Spring Festival in addition, is again a kind of rare ornamental flower in red-letter day.
The common primrose of China are more common in the Europe series of heralding spring, and do to see early spring the seeds of flowering plants more and plant, and the application of wild common primrose is still rare.Yunnan sea daffodil is planted in during as the Spring Festival views and admires colored in garden, flower bed or the flowerpot, and its application prospect is very good.But because its growing environment is destroyed, make the field distribution day of sea, Yunnan daffodil more reduce, seriously restricted the industrialization development of this seeds of flowering plants.
Summary of the invention
The present invention is directed to Yunnan sea daffodil and day more reduce the problem that influence industrialized development, provide that a kind of breeding is easy, reproduction speed is fast, can promote the method for cutting and propagating creeping stems of primula pseudodenticulata pax view of industrialized development because of the field distributes.
The present invention realizes by following technical proposal: a kind of method for cutting and propagating creeping stems of primula pseudodenticulata pax view is characterized in that may further comprise the steps:
1) behind sea, Yunnan daffodil plant harvesting stolon, has been cut into 1/3 blade, the plugged ear of the long 5～6cm of stem;
2) be in the matrix of following mass ratio of 8～10cm with above-mentioned plugged ear cuttage at thickness: soil: humus soil: perlite=1: 1～2: 1～2, the control cuttage degree of depth is 3～4cm, cutting density is that the plugged ear blade is not overlapping;
3) water irrigates matrix after the cuttage, covers with plastic film and sunshade net, and carries out management after the cuttage routinely, after 20～25 days, gets final product hardening.
Described 2) soil in the matrix of step is laterite, perhaps the garden mould in the vegetable garden.
Described 2) to be laid on width be 100cm to the matrix of step, and length is on the seedbed of 250～300cm, and the mass concentration that adopts 1000 times of dilutions is that 5% liquor potassic permanganate irrigates matrix and carries out disinfection, and carries out cuttage after 24 hours.
Build the shed that adapts with it on the described seedbed, and after adding a cover plastic film on the shed, add the sunshade net, making things convenient for the water supply in media after the cuttage, ambient humidity, illumination and temperature, the extermination of disease and insect pest, management such as nutrient supply are until hardening.
Described 3) management after the cuttage is as follows in the step:
The management of water supply in media and ambient humidity: two weeks after the cuttage, keep water content of substrate 60～70%, ambient air humidity 80～90%, treat that plugged ear is taken root after, keep water content of substrate after 30～40%, 15～20 days, open film and ventilate;
Illumination and temperature treatment: the temperature that controls environment after the cuttage is at 25～30 ℃, and degree of shading is 40～60%;
The extermination of disease and insect pest: after the cuttage,, spray active constituent content and be 800 times of solution of carbendazim of 40～50% once, and in time remove the diseased plant of finding every 15 days;
Nutrient management: after treating the cuttage rooting leave after the cuttage, spray mass concentration and be 0.1% urea liquid, spray number of times for once every 5～7 days;
Hardening: after the cuttage 20～25 days, there is 40% plugged ear to begin to take root, and grows young leaves, can progressively open the film of covering this moment, and suitably ventilate; Behind the cuttage rooting more than 60%, can open whole films, carry out hardening.
The present invention compared with prior art has following advantage and effect: adopt such scheme, promptly utilize the stolon of sea, Yunnan daffodil directly to carry out cuttage, not only plugged ear is easy to get, quantity is big, and cuttage is easy, reproduction speed is fast, the hardening stalwartness that obtains, insect protected, resistance against diseases is strong, transplant the back survival rate and reach 60～70%, it is high to help sea, Yunnan this sight of daffodil, florescence is long, leaf look gratifying and four seasons evergreen flowers industrialized development, the method that the invention provides is fit to the weather soil environment of China very much, the celestial flower variety of the Yunnan seawater that obtains is good, thereby, have vast market prospect.
