Abstract

The invention discloses a single stem plant digitalized construction method based on a growth model and relates to the technical field of agricultural information. The method comprises the following steps of (1) preprocessing experiment observation data and establishing the growth model of a single stem plant through statistic package for social science (SPSS) statistical software; (2) establishing an assimilation reallocation model based on a plant structure; (3) reconstructing plant morphologic change and establishing a single stem plant digitalized model; and (4) achieving digitization of a single stem plant. A plant growth model is obtained through experiments, a plant digitalization model capable of reflecting plant growth mechanism accurately is established and computer simulation of the plant growth process is achieved due to the model so that plant growth and development in different external environments can be forecasted due to a plant digitalization result.

Description

Technical field:

[0001] The invention relates to the field of agricultural information technology, in particular to a growth model-based single-stem plant digital construction method. Background technique:

[0002] With the rapid development of digital agriculture, digital agriculture and forestry technologies are gradually being applied to related fields of agriculture. For example, digital plants are beneficial to the improvement of plant shapes, and can provide intuitive scientific basis for predicting the external environmental conditions suitable for plant growth. "Plant digitization", as an organism combining modern agricultural technology and information technology, refers to the reconstruction of plant growth information so that it can be simulated on a computer in an intuitive and visual way. At present, the existing plant digitalization methods mostly simulate plants for a certain purpose. For example, in order to achieve realistic simulation effects, some static v...

Examples

Embodiment

[0039] Embodiment: An artificially cultivated single-stem plant——reed is taken as an example to illustrate the digital construction method of a single-stem plant based on the growth model proposed by the present invention. The program is implemented in five steps:

[0040] Step 1: Build a growth model of a single-stem plant

[0041] The dynamic model of stem growth of a single-stem plant is obtained through experimental observation, that is, the relationship model of the stem height and the number of internodes of the plant with the cumulative growth degree day; the dynamic model of the leaf area index, that is, the relationship between the leaf area index and the cumulative growth degree day. Model; the relationship model of plant dry matter distribution with cumulative growth degree days; the dynamic model of plant dry matter distribution, that is, the relationship model of plant dry matter distribution with cumulative growth degree days.

[0042] Obtained from the experime...
