Embodiment 1

[0044] Basic conditions and methods for cutting propagation of Begonia plants:

[0045] The stems and leaves of Begonia plants have the ability to regenerate and can be used as cutting propagation materials. Based on the theoretical basis of the orthogonal experimental design of biostatistics, the main factors affecting the rooting and seedling growth of cuttings were listed, and the orthogonal experiments of 4 factors and 3 levels were carried out, as well as the multi-group comparative cutting experiments. The results of comprehensive analysis show that whether it is stem node cutting or leaf cutting, perlite is the best cutting substrate, the cutting bed temperature is 22-28°C, the substrate temperature is 18-22°C, and the air relative humidity of the cutting bed is controlled at 60-28°C. 75%, the cutting bed is shaded with cold gauze and covered with plastic film. It is advisable to keep the cutting bed 70cm away from the ground, keep the drainage and ventilation good, wa...

[0061] Intensive Leaf Cutting Propagation of ‘Red-haired’ Begonia (B. ‘Fireflash’):

[0062] Provenance and its ornamental characters:

[0063] 'Red-haired' begonia (B.'Fireflash') was introduced and cultivated from the UK in 1998. It is an exotic horticultural variety with rhizome type. It can grow robustly under slightly strong light and low humidity conditions, and has certain cultivation adaptability. The plant is densely covered with purple-red villous hairs, and the young leaves are particularly bright purple-red villous. The leaves are medium-sized, brown-green, with purple-brown palmate stripes inlaid in the center, which has high ornamental value.

[0064] Basic conditions and measures for leaf cutting propagation:

[0065] Build a cutting bed 70cm away from the ground in the sun board or plastic film room, arrange geothermal heating in the bed, and connect the automatic induction temperature control device to control the temperature of the substrate. tube to increa...

[0079] Intensive leaf cutting propagation of 'Plant Bird' Begonia (B.'Plant Bird'):

[0080] Provenance and its ornamental characters:

[0081] 'Plant Bird' Begonia (B.'Plant Bird') is a new variety with independent intellectual property rights registered in Kunming Institute of Botany, Chinese Academy of Sciences in 2001, from Begonia 'White King' ('White King' Begonia) and B. Sexual hybrid F of hemsleyana (Begonia palmatum) 1 Selected from a generational population. 'Plant Bird' begonia (B.'Plant Bird') leaves are oval in outline, 4-5 lobed, brown-green on the leaf surface, with silver-green ring markings along the lobes, and have high ornamental value.

[0082] Basic conditions and measures for leaf cutting propagation:

[0083] Build a cutting bed 70cm away from the ground in the sun board or plastic film room, arrange geothermal heating in the bed, and connect the automatic induction temperature control device to control the temperature of the substrate. tube to incre...

Abstract

Cutting propagation method of begonia leaf regards begonia leaves as cutting slips and regards perlites as cutting medium. Cuttage is proceeded by utilizing a cuttage bed or a cuttage container tray at the height of 60 70 centimeters above the floor. Begonia of stem cuttage can take roots and form shoots in 20 25 days and the rooting rate can reach 90 95 %. Begonia of leaf cuttage can take roots in incision in 15 20 days, produce adventitious buds and form new plants in 60 75 days. And the rooting rate of the Begonia of leaf cuttage can reach 75 85 %. Cutting propagation method of begonia leaf has the advantages of being simple in method, convenient to operate, large in the acquiring base of the cutting slips, fast in adjustment, high in efficiency and realizable in 75 % rooting rate.

Description

[0001] Technical field: [0002] The invention belongs to the field of biotechnology, and in particular relates to an intensive leaf cutting propagation method, cultivation and conservation, and large-scale potted flower cultivation production technology of Begonia plants. [0003] Background technique: [0004] There are more than 1,600 species of Begonia L. plants in the world, which are widely distributed in tropical and subtropical regions, and are also distributed in temperate regions. China is one of the countries with rich natural distribution of Begonia plant species. There are 224 known and published species, of which 197 species are unique to China, accounting for about 87.9% of the species distributed in China. Yunnan is located in the southwestern border of China, and is extremely rich in plant species, especially Begonias. There are 110 known and published species, accounting for about 49.1% of the natural distribution species in China, of which 74 species are uniq...
