Description

A kind of method of Flos Camelliae Japonicae or Rhododendron hybridun cutting propagation

Technical field

The invention belongs to plant cuttage seedling propagating technology field, be specifically related to a kind of Flos Camelliae Japonicae or Rhododendron hybridun cuttage and seedling culture method.

Background technology

Flos Camelliae Japonicae and Cuculus polioephalus Huadu are famous ornamental plants. Act not only as pot flowers, and in garden landscape is built, make scape for isolated planting, mass-planting and artificial hillock and use, it is also possible to for city public greening, courtyard greening, flower show and Fresh Cutting flower and floral holding material etc.

The breeding of Flos Camelliae Japonicae mainly has seminal propagation and asexual propagation. But seed propagation is it is generally required to 57 years just can bloom, therefore the breeding of Flos Camelliae Japonicae to adopt asexual propagation to be main, can keep woody inherited character, can bloom ahead of time again, and cottage propagation speed is fast, and material economizes, effective. Cottage propagation is one the most frequently used in asexual propagation, because its operating technology is less demanding, not limited by the field, breeding coefficient high and extensive use aborning (Peng Yuhua and Liu Shanrong. Flos Camelliae Japonicae Various Seasonal cottage propagation Preliminary Report on Experiment. Guangxi forest-science, 2001,30 (2): 86 87). The rooting rate of different cutting medium significant impact Flos Camelliae Japonicaes. 1/2 volcanic soil+1/2 laterite as cutting medium be conducive to the cuttage root-taking of Camellia reticulata (Yang Yuexian and by great waves. the exploration of Camellia reticulata cutting medium. Crop Diseases in Yunnan, 2010:30 32). After processing Flos Camelliae Japonicae cutting with ABT1 root-inducing powder in the winter time, there is significant difference in the cutting plantation in river sand, Vermiculitum and sawdust, wherein the rooting rate of sawdust can reach 90% (Zhao Yuhong, Deng. Cuttage for Reproduction of Camellia japonica L is studied. Agriculture of Anhui science, 2005,33 (5): 830 831). Zhejiang Flos Camelliae Japonicae cuttage survival rate in river sand is the highest, and not notable with Vermiculitum, perlitic difference (Gao Changbao. the different substrates impact on Zhejiang Flos Camelliae Japonicae cottage propagation. China's Forest by-product and speciality, 2012,2:40 42). After processing camellia azalea with GGR 6 root-inducing powder, using peat soil: the mixed-matrix that loess is 1:1 can obtain the rooting rate (Wang Youbing of about 70% as its cutting medium, Deng. the different substrates impact on camellia azalea cuttage root-taking. Annual, 2011,2 (27): 54 59).Black Paeonia suffruticosa Flos Camelliae Japonicae cuttage result is had large effect by different substrates, best by the effect that peat soil is cutting medium, its cuttage average survival, on average take out tip number, on average take root number, average root length and the longest root length (Du Ling effective compared with loess and river sand, Deng. black Paeonia suffruticosa Flos Camelliae Japonicae cottage propagation is tested. north gardening, 2014,07:69 71).

Different plant growth regulator kinds is notable on the impact of Flos Camelliae Japonicae rooting rate, and simultaneously different cuttage rooting rates in season is also different. After processing Guizhou Camellia with the ABT root-inducing powder of low concentration, good effect can be obtained as cutting medium using Vermiculitum and original soil, and with JIUYUE and June cutting experiment better (Hu Guangping, Deng. endemic species Guizhou, Guizhou Camellia cottage propagation is studied. Agriculture of Anhui science, 2013,41 (15): 6,631 6633). The cuttage root-taking of Lucheng City spring, Chu butterfly, white seedling tea and 4 kinds of Flos Camelliae Japonicae of East China Flos Camelliae Japonicae is all had the effect of remarkably promoting by the variable concentrations of IAA, IBA, NAA, IAA+NAA (1: 1 mixing) and IBA+NAA (1: 1 mixing), survival rate (the Li Guoshu of Flos Camelliae Japonicae cutting can be significantly improved, Deng. the impact on Flos Camelliae Japonicae cuttage root-taking of the several plant growth regulator. north gardening, 2011 (14): 65 69).

Comprise additionally in Cutting conditions, as full exposure spray technique (Wu is deep. C.chekiangoleosa full sunshine and spray cuttage technique is studied. agriculture in south, 2014,27 (7): 7 8). Irradiation also can the taking root of appreciable impact Flos Camelliae Japonicae; 5 one 15Gy are cutting plantation and the quality that suitable exposure dose affects Flos Camelliae Japonicae, mean elements, average root length and the longest root length all reach maximum, and higher than comparison (Li Xinlei, Deng. irradiation Flos Camelliae Japonicae cuttage root-taking characteristic research. nuclear agricultural science report, 2008,22 (2): 156 159).

Rhododendron seeds breeding planting percent low, Partial Species from seed propagation to bloom needs about 6 10 years (Zhang Changqin. the cross-breeding of Folium Rhododendri Simsii. Beijing: China Forestry Publishing House, 2000:403 411.). The cottage propagation of Folium Rhododendri Simsii is also without being solved fully, as the effect of different types of Folium Rhododendri Simsii cottage propagation is existed the (Geng Xingmin such as the rooting rate of significant difference, different hormone kinds and concentration appreciable impact Folium Rhododendri Simsii cottage propagation and planting percent, part its rooting rate of Folium Rhododendri Simsii type be extremely low by different cottage methods, Deng. rhododendron cottage propagation progress. Chinese Wild plant resources journal, 2011,30 (6): 16; Wang Dingyue, etc. Rhododendron in Lushan Botanical Garden Research Advances on Breeding. Agriculture of Anhui science, 2012,40 (32): 15,622 15625,15627; Zheng Liyun, etc. the different substrates impact on Cuculus polioephalus cuttage survival rate. Chinese flower gardening, 2013.12:28 30; ), seriously constrain the industrial seedling rearing of azalea resource and making full use of of resource. Rhododendron hybridun cottage propagation is method conventional in producing, Chinese scholars is extensively respectively adopted the factors such as the combination of different cutting time, different cutting medium, different cottage method, hormon and concentration and has carried out the cottage propagation research work of Rhododendron hybridun (use force in osmanthus, Deng. belgian azalea different substrates Cutting test. modern agriculture science and technology, 2005,3:54 56; StrzeleckaK.2007.Anatomicalstructureandadventitiousrootf ormationinRhododendronponticumL.cuttings.ActaScientiarum Polonorum, 6 (2): 15 22.), research finds in Rhododendron hybridun cottage propagation process the appreciable impact such as auxin concentration and kind, genotype, cutting medium kind it is taken root.

As can be seen here, no matter it is Flos Camelliae Japonicae or Cuculus polioephalus, the processing method of their different types of cutting for cottage propagation, use the kind of hormone and concentration, cutting medium and Cutting conditions etc. to be not quite similar, and the cuttage root-taking of variety classes and different cultivars exists significant difference. So far, it is successfully applied to Flos Camelliae Japonicae or the report of Rhododendron hybridun cottage propagation but without a kind of quick, easy and without pre-treatment cuttings such as hormones method.
