Description

A kind of method of Chinese rose seedling growing block cuttage and seedling culture

Technical field

The invention belongs to the cuttage and seedling culture propagation technique field of Chinese rose, be specifically related to a kind of method of Chinese rose seedling growing block cuttage and seedling culture.

Background technology

Chinese rose (Rosachinensis) is perennial fallen leaves or the evergreen shrubs of rose family Rosa, and originate in China, be one of famous flower and tree that kind is maximum in the world, it is of many uses, has the good reputation of " spending middle queen ", " spending middle queen ".The breeding of Chinese rose adopts propagation by grafiting more, but propagation by grafiting is subject to technology content, the quantitative limitation of stock number, and nursery that cannot be a large amount of.Cottage propagation has good characteristic, the advantages such as morning of blooming that relative skill requirement is low, reproduction speed is relatively fast, well can keep female parent, and be well positioned to meet market demand (Gong Zhongxing. plant growth regulator is on the impact of Liana rosa indica cuttage root-taking. Agriculture of Anhui science, 2014,42 (28): 9719,9724).

Trace element and plant growth regulator affect the cuttage survival rate of Chinese rose significantly.Trace element lanthanum can promote the cuttage survival rate of Chinese rose ' fragrant cloud ' significantly, effect be better than 5ppm indolepopionic acid effect (Wu Zhaoming. the impact of lanthanum and Indolepropionic Acid On Rooting of Rose Cutting. gardening journal, 1988,15 (1): 69 ?72).The quickly dipped process of 1000mg/LIBA+IAA " Angela " rooting rate can reach 90%, survival rate is 88%, root growth also the feature such as the most healthy and the strongest (Gong Zhongxing. plant growth regulator is on the impact of Liana rosa indica cuttage root-taking. Agriculture of Anhui science, 2014,42 (28): 9719,9724).Different cutting mediums, matrix disinfectant kind have significant impact to the cuttage survival rate of different modern rose cultivarses and cuttage quality.With the peat composed of rotten mosses: perlite is that the mixing cutting medium of 2:1 has good cutting experiment to Growth anddevelopment kind ' the golden sun ' (last month of spring is beautiful, Deng. different substrates is on the impact of Growth anddevelopment cottage propagation. Shanghai Communications University's journal (agricultural science version), 2010,28 (3): 275 ?279).Using vermiculite and perlite as cutting medium, the rooting rate of Rosa floribunda can reach 78.89% and 75.55% (Luo Jie, etc. different substrates is on the impact of Cuttage Propgation of Semi-ripe Rose Branches. Agriculture of Anhui science, 2005,33 (7): 1211 ?1212,1283).After 40% formaldehyde carries out disinfection to cutting medium cuttage Chinese rose can obtain good cutting experiment (Li Zhentao, etc. the screening of Chinese rose cutting medium disinfectant. Liaoning agricultural science, 2014 (2): 66 ?67).Cuttage after the equivalent NAA of 250mg/L and the quickly dipped Chinese rose cuttings of IBA mixed liquor 2 ~ 3s, with peat: when perlite is 2:1, cuttage survival rate can reach 95.33% (Yan Haixia, Deng. methyl α-naphthyl acetate and indolebutyric acid are on the impact of Chinese rose cutting survival effect. agriculture in south journal, 2013,44 (11): 1870 ?1873).Application number is the Chinese invention patent " medicinal Chinese rose cuttage method " of CN103503668A, described content comprise choose rawly then to enrich, axillalry bud not yet spues bud new slightly, clip 3 ?5 save as cutting, insert in soil, insert lower after water sufficient water.Authorization Notice No. is the Chinese invention patent " Liana rosa indica cuttage breeding method " of CN102090304B, institute's those set forth comprises the Chinese invention patent " a kind of method improving cuttage survival rate of rose " that application publication number is CN101627696A, institute's those set forth comprises and adopts chaff ash in ridge as cutting medium, seedbed with 300 times 30% carbendazim solution process; Rise call the carbendazim solution process of 500 times 30% after use again 500 ?1000mg/L the quick libation at an ancient wedding ceremony liquid of heteroauxin solution after cuttage in matrix, adopt full exposure spraying method.Application publication number is CN105010101A Chinese invention patent " a kind of Chinese rose cuttage breeding method ", institute's those set forth comprise cuttings is cut into 8 ?the cuttings of 10 centimetres; Disinfect; Cuttings with 100 ?150mg/L NAA and 100 ?150mg/L IBA mixed liquor process 10 ?15min; Cutting medium be peat, perlite, vermiculite by volume 1 ?the mixed-matrix (0.5 ?1wt% disinfecting solution of potassium permanganate) of 3:1:1.Application number is the Chinese invention patent " Chinese rose Water culture propagation method " of CN104303969A, the selection and process, the preparation of culture fluid, the water planting that comprise cuttings are cultivated, daily management, acclimatization and transplants, described step comprise cuttings clip 10 ?15 centimetres, the carbendazim of 500 times 30% soak 5 ?15min, 30 ?50mg/KgABT solution soak 2 ?4 hours, 1/2Hoagland nutrient solution is added with homemade cuttage case, within every 7 days, with changing one time of nutrition liquid, transplant in furrow to transplanting when root grows to 1 ?2 centimetres.Simultaneously Chinese rose cottage propagation also by the aspect such as cutting time, cottage method impact (Li Shan. Chinese rose Technique on Cuttage Propagation progress. Jiangsu forestry science and technology, 2009,36 (6): 47 ?49).

As can be seen here, Chinese rose cottage propagation is a very complicated physiology course, and influence factor is different, survives complexity also different.The processing method of cutting in the Chinese rose cottage propagation of the Different Individual of the even same kind of variety classes, different cultivars, the kind of use hormone and concentration, cutting medium and Cutting conditions etc. are not quite similar, and cuttage root-taking exists significant difference.So far, also do not have a kind of quick, easy and be applied to the report of Chinese rose cottage propagation without the method for the pre-treatment cuttings such as hormone.
