Embodiment 1

[0032] A: A method for rapid screening of high-quality spring Dendrobium potted varieties

[0033] (1) Investigate different varieties to obtain raw data reflecting the population traits of Dendrobium dendrobii cultivars. The objects of the survey are three-year-old varieties that are about to bloom, including large-flowered, medium-flowered, and small-flowered types, single-branched, double-branched, and triple-branched mature pseudobulbs, and red, yellow, and white tricolors. 15-25 plants of each variety were randomly selected, and the following 24 traits were investigated respectively:

[0034] Initial florescence x1 (measurement method: the time that reaches 10% from the beginning of processing to flowering rate; Unit: day),

[0035] The full flowering period is long x2 (measurement method: from 30% of the flowering rate to the time when the remaining flowering amount accounts for 50% of the total flowering amount; unit: day),

[0036] The total flowering period is long ...

[0070] B: Method for rapid screening of high-quality spring dendrobium plants

[0071] (1) Investigate the Dendrobium officinale cultivar V1, and obtain the original data reflecting the population traits of V1. Randomly select 85-100 three-year-old V1 varieties, and investigate the above 24 traits according to the A(1) method;

[0072] (2) Determine the indicators and weights for comprehensive evaluation of high-quality potted plants of V1 varieties. Using the A(2) method to get the weight λ of the 10 indicators in the comprehensive impact of quality i =∑π i *n i (Table 4).

[0073] Table 4 Simplified indicators of the V1 variety screened out and the weight of each indicator

[0074]

[0075] (3) Establish a single-factor grading standard system for V1 varieties, and classify the single-factor grades of Dendrobium dendrobii. According to the distribution range of different quantitative traits of V1 varieties, the above 10 indexes were divided into the following 5 grad...

Abstract

The invention belongs to the technical field of flower breeding in gardens and in particular relates to a method for fast screening dendrobium nobile potted flower with high quality; the method is characterized in that: in a flowering phase of a potted dendrobium nobile, exhibiting characteristic value F of different varieties or the same variety among different plants is obtained by surveying, analyzing and screening the indexed which reflect the plant quality among the varieties and in the save variety and setting the index parameter values, and the quality of the potted flower of the dendrobium nobile is divided into five grades according to the size of the value, and the obtained result for testing the potted flower with high quality can accurately reflect the quality characteristics of the tested potted flower of the dendrobium nobile. The method provides scientific, simple and practical index and method for the screening of the high-quality potted flower of the dendrobium nobile and is the basis for building the digital agriculture.

Description

technical field [0001] The invention belongs to the technical field of garden flower breeding, and in particular relates to a method for quickly screening high-quality spring dendrobium potted flowers. technical background [0002] Dendrobium, a perennial herbaceous plant of the genus Dendrobium in the family Orchidaceae, belongs to the epiphytic orchid class. Dendrobium orchid has a beautiful posture, gorgeous flowers, tall and straight stems, and a flowering period of up to 3 months. It is very popular among people in Southeast Asia. Dendrobium can be divided into spring Dendrobium and autumn Dendrobium according to the different flowering periods. The natural flowering period of Dendrobium dendrobium is in autumn, and it is a terminal inflorescence class, which is often used as cut flowers. Dendrobium dendrobium is an arthropod inflorescence, with a plant height of 30-100cm and green leaves. The upright pseudobulbs are flat and cylindrical. The flowers are huge, rich i...
