A wheat growth form model establishing method and device

Abstract

The invention provides a method and a device for establishing a wheat growth form model. The method is used for establishing a wheat growth form model in combination with a wheat growth model. The method comprises the steps of according to meteorological parameters in a wheat growth model, dry matter weight of the wheat organs and morphological characteristic relationship between the two and the wheat organs establishing a morphological characteristic parameter model, obtaining field test data including meteorological data, wheat organ characteristic data and wheat organ dry matter weight data, fitting to obtain numerical values of model parameters in the morphological characteristic parameter model according to the field test data and the morphological characteristic parameter model, anddetermining a wheat growth morphological model. According to the wheat growth morphological model and the parameterized geometric modeling method, the wheat growth model is constructed through biomass, the constructed model is higher in mechanology and universality, and the constructed geometric parameter model of wheat leaves, leaf sheaths and stems is better in reliability and practicability. The wheat growth morphological model and the parameterized geometric modeling method are used for constructing the wheat leaf, leaf sheath and stem geometric parameter model.

Description

technical field [0001] The invention relates to the field of virtual agriculture, in particular to a method and device for establishing a wheat growth shape model. Background technique [0002] As digital agriculture has become an important technical support for the development of modern agriculture. Digital agriculture plays an important role in improving agricultural production efficiency, improving the quality of agricultural products, and protecting the agricultural environment. Among them, the agricultural model is the basis of digital agriculture and occupies an important position in digital agriculture. At present, no matter the wheat growth model or the wheat morphological structure model, the two only focus on function or structure respectively. The wheat growth model simplifies the structural and morphological characteristics, while the morphological structure model often ignores the functional process and only shows an example. The structure of wheat, in the prio...

At present, no matter the wheat growth model or the wheat morphological structure model, the two only focus on function or structure respectively. The wheat growth model simplifies the structural and morphological characteristics, while the morphological structure model often ignores the functional process and only shows an example. The structure of wheat, in the prior art, there are few studies on the combination of wheat growth model and morphological model, and there is a lack of effective methods for combining wheat growth model and morphological model
