Single stem plant digitalized construction method based on growth model

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...

Problems solved by technology

Subsequently, many experts proposed various methods and models for generating plant graphics to simulate the growth process of plants, the most representative of which is: in the 1990s, the virtual plant laboratory of the University of Calgary in Canada, led by Prusinkiewicz, studied different L- The system theory and application are reviewed, and some progress has been made in the simulation of plant growth process, but it is limited to the simulation of some simple plants, and there are deficiencies in simulating the physiological and ecological characteristics of specific plants; at the end of the 20th century, the French International Agricultural Development Research Institute Center de Reffye et al. developed the AMAP plant growth software system based on reference axis technology. This system can simulate 23 common types of plant morphology and its topological structure, but the simulation of the physiological and ecological characteristics of plants still exists. Insufficient, most of the changes are based on empirical data or based on aesthetic views, and it is difficult to establish a connection with the actual growth laws of plants, especially the morphological structure and ecological physiological changes of plants caused by the interaction between plants and the environment cannot be truly simulated

[0004] Insufficiency of using the L system series method to digitize plants: because the plant growth model obtained from experimental observations is not effectively used in modeling, the plant digital model constructed cannot faithfully reflect the plant growth mechanism, making it difficult to achieve plant growth The computer simulation of the process, so it is impossible to predict the growth and development of plants under different external environmental conditions through the results of plant digitization
