Abstract
The invention discloses a potentilla sericea cutting propagation method, relates to a potentilla sericea asexual propagation method, and aims to solve the technical problems of slow rooting and low propagation coefficient in soil cutting strip burying propagation of potentilla chinensis in the prior art. The method comprises the following steps: shearing cutting slips from creeping stems having over three nodes at an establishment period; putting the cutting slips into small molecular group water for culturing, and transplanting after rooting; finishing cutting propagation of potentilla sericea. The method is used for propagating the potentilla sericea, and has the advantages of quick rooting, high propagation coefficient and high survival rate. Plants formed by using the method can be suitable for rapid formation of landscaping and garden landscapes, and the method has the advantages of high stress resistance, water saving, drought resistance, reduction of trimming, extensive management and low maintenance cost. The propagation coefficient of young seedlings cultured by using the method can be up to 7.12, the survival rate of the young seedlings is over 90.77 percent, and root systems are developed and grow robustly.
Description
Technical field
The present invention relates to a kind of vegetative method of thin,tough silk hair potentilla chinensis.
Background technology
Thin,tough silk hair potentilla chinensis (Potentilla sericea) is rose family Potentilla herbaceos perennial, there is certain ornamental value, in April to August, the animated period of thin,tough silk hair potentilla chinensis growth, its pattern is gorgeous be a kind of good early spring and time early summer sight flower ground cover plant, and there is stronger resistance and can adapt to north cold, dry climate environment, underground well developed root system, Gu native ability is strong, acrial part is flourishing, cover degree has greatly good water conservation, conserve water and soil and bank protection effect, therefore be well suited for being applied in urban landscaping as ground cover plant.
Thin,tough silk hair potentilla chinensis is as wild resource, and germ plasm resource quantity is very limited, how Fast-propagation be determine promoted extension and speed key.Thin,tough silk hair potentilla chinensis does not have seed, is generally at present to breed with root, and this is also apply maximum modess of reproduction.But it is low that shortcoming is reproduction coefficient, and after the plant of life in several years grows up to, leaf senescence is hard, and color does not have the color of a biennial new plant vivid yet.The ornamental value that can not show a candle to new plant is high.Therefore, researching and developing a kind of method of Rapid Rooting, cost-saving, Fast-propagation, is the technical problem of being badly in need of at present carrying out in this research field.
At present, existing potentilla chinensis adopts soil cuttage underground layering to breed, exist propagating cuttage coefficient low, take root slow, about can form the larger effect of coverage rate after one month.
Summary of the invention
The present invention will solve existing potentilla chinensis and adopt the breeding of soil cuttage underground layering to there is the technical problem slow, reproduction coefficient is low of taking root; And provide the method for thin,tough silk hair potentilla chinensis cottage propagation.The present invention utilize thin,tough silk hair potentilla chinensis stolon carry out planting, reach and improve thin,tough silk hair potentilla chinensis reproduction coefficient, expand cultivated area, promote nursery stock application, be applied in the plantation of hillside fields, increase green coverage, reduce costs.
In the present invention, the method for thin,tough silk hair potentilla chinensis cottage propagation is carried out in the steps below: in the planting phase, selects the stolon clip cuttings having more than 3 stipes; Then cuttings is put into after small-micelle water is cultured to out root and transplant; Complete thin,tough silk hair potentilla chinensis cottage propagation.
Described cuttings at least retains a stipes, at least stay 1 blade.
Choose and make cuttings containing Section three or Section of three later stipes.
Long 2 ~ the 4cm of described cuttings.
The upper cut distance adventive root 1 ~ 2cm of described cuttings, be cut into inclined-plane, obtuse angle, lower cut is cut into acute angle bevel at 1 ~ 2cm place, adventive root bottom.
Within in incubation every 2 ~ 5 days, change a water.
In transplanting turfy soil, water permeable after transplanting, and add a cover shade net.
Can be that 3:1 proportioning makes turfy soil by soil and the mass ratio of the peat composed of rotten mosses.
Micromolecular water infiltrates in cell fast, activates the growing point of thin,tough silk hair potentilla chinensis, makes its Rapid Rooting.
The stolon of technology to thin,tough silk hair potentilla chinensis of water planting that the present invention utilizes carries out stem segment cuttage, can in whenever carrying out, fast compared with the rooting rate of the cuttage carried out in soil, and after transplanting, survival rate can reach 100%.Fast-propagation seedling, reduces costs input.
The present invention cultivates seedling can rise to 7.12 by reproduction coefficient, and seedling percent reaches more than 90.77%, well developed root system and growing way is good, survival rate 100% after transplanting, mass, factorial praluction, method is simple to operate, equipment needed thereby is simple, breeds without the need to professional person.Individual with low cost, the survival rate of the seedling of breeding is high, is easy to promote.
The plant that the inventive method is formed can be suitable for the rapid formation of afforestation, courtyard landscape design, has strong stress resistance, saving water, resisting drought, minimizing pruning, extensive management, advantage that maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is the photo of the 1st day situation of taking root; Fig. 2 is the photo of the 5th day situation of taking root; Fig. 3 is the photo of the situation of taking root of the 10th day.
Embodiment
Embodiment one: in present embodiment, the method for thin,tough silk hair potentilla chinensis cottage propagation is carried out in the steps below: Harbin June, plant strain growth is chosen good large Tanaka, without rust staining and insect pest, growing way is basically identical, the thin,tough silk hair potentilla chinensis of stipes joint number more than four; Clean up with in clear water, clip cuttings, get the stem section of Section 4-Section 10, cuttings retains a stipes, at least stays 1 blade, the upper cut distance adventive root 1cm of cuttings, be cut into inclined-plane, obtuse angle, lower cut is cut into acute angle bevel at 1cm place, adventive root bottom; Then cuttings is put into the conical flask that small-micelle water is housed, cultivate at 25 DEG C, within every 5 days, change a water, illumination only needs indoor astigmatism normal every day, cultivating and migrating to soil with the mass ratio of the peat composed of rotten mosses after 15 days is in the turfy soil of 3:1, waters permeable, and add a cover shade net after transplanting; Complete thin,tough silk hair potentilla chinensis cottage propagation.
