Extraction method of rice plant morphological structure index and its application

Abstract

The invention discloses a rice-plant morphological structure index extracting method and an application thereof, and relates to the field of plant morphological structure index extracting and applying. The rice-plant morphological structure index extracting method includes the steps that S1, a digitalized rice morphological structure is built, and space position information and geometrical morphology information of groups, rice plants, stem yeast and leaves are organized according to different levels; S2, based on the digitalized rice morphological structure, rice morphological structure feature distribution is extracted with a virtual blade technology; S3, based on rice morphological structure feature distribution, rice morphological structure indexes are calculated; S4, a combination of the morphological structure indexes serves as a decision variable, dry matter accumulation or yield serves as the target, and the dry matter accumulation capacity or the production potential of the morphological structure is evaluated. The rice-plant morphological structure index extracting method and the application can provide quantification indexes and method supports for researching of accurate plant type seed selection, morphological structure agricultural control and function and structure models.

Description

technical field [0001] The invention relates to the field of extraction and application of plant morphological structure indexes, in particular to the extraction and application of rice morphological structure indexes. Background technique [0002] Plant type refers to the morphological structure of the plant, that is, the morphological characteristics of the plant, the spatial arrangement and the relationship between various traits, such as the height of the plant, the distribution of tillers, the length, width and angle of the leaves, the shape of the ear, and the position of the individual in the group. Arrangement and its geometric structure, etc. [0003] The morphological structure of rice is controlled by rice genotype and regulated by environmental factors such as water, fertilizer and climate; the morphological structure of rice affects the microclimate of the population canopy, especially the interception of solar radiation energy, which in turn affects the accumul...

Problems solved by technology

One of the important reasons is the difficulty in extracting crop morphological and structural indicators. For example, many breeders prefer rice varieties with compact and moderate plant size, but there is still no suitable method to quantify the indicators describing the degree of plant compactness.
