Abstract

Bengonia sanlie is prepared by performing artificial pollination hybridization on B.cirrosa serving as a female parent and B.fangii serving as a male parent as well as selecting from the obtained F1 generation group to perform cultivation. The specificity is as follows: a leaf has 3 to 4 cracks, the leaf surface has hair, the petiole is densely pubescent, and the flowering number is large (10 to 20 flowers / inflorescence). Moreover, the Bengonia sanlie has the excellent properties of high cultivation adaptability, that is, the perianth lobe is pinkish, the bengonia sanlie blooms in January to April, and the leaf is green and palm-shaped and has 3 to 4 shallow cracks. The bengonia sanlie is cultivated by a matched nutritional medium with the ratio of humus soil to perlite to mossy fiber to PK fertilizer being 40:3:3:0.5, and the bengonia sanlie can grow under the cultivation conditions that the average room temperature is 20 DEG C, the average air relative humidity is 50 percent and theillumination intensity is 15000 to 20000 Lx. Oblique illumination is properly increased in the flowering period, phosphorus potassium fertilizer is additionally applied, the flowering number of the plant is large, and the flower is big and has bright color.

Description

[0001] Technical field: [0002] The invention belongs to the field of biotechnology, and in particular relates to a method for cultivating a new variety of Begonia, and a new variety 'Sanlie' (B. 'Sanlie') obtained by cultivating the method; Crack 'Cultivation method. [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 unique ...
