Rice plant type quantitative control method integrating crop virtual growth model

Abstract

Provided is a rice plant type quantitative design method integrating a crop virtual growth model. The crop virtual growth model is constructed, effective correlation and combination of the main plant physiological process, morphological structures and a light environmental model are achieved, and visual virtual growth of crop plants can be achieved; in the crop virtual growth model, morphologies of crops at different growth periods are set up through a structure model, a physiological model is used for realizing dynamic prediction of production, distribution and final yield of crop assimilates, and the light environmental model is used for computing crop canopy light radiation quantity and crop individual fractional interception of photosynthetic active radiation; the crop plant type structure is continuously changed through an optimization algorithm, so that simulation results of different adaption degrees are obtained, and the optimal crop plant type based on different targets can be obtained; the different adaption degrees are used as optimization results of the targets and set as morphological parameters of the virtual growth model, analog operation is carried out, horizontal and longitudinal comparison is carried out, and the optimal plant type data of crops are verified and determined.

Description

Technical field [0001] The content of the present invention relates to the fields of plant virtual modeling, plant physiology and ecology, and optimization algorithm design. It is a crop plant type control method that can realize automatic crop plant type optimization, and can be applied to the quantitative control and design of crop plant type. Background technique [0002] After a long period of development, traditional breeding has formed a complete set of breeding theory and technical system, and has made great achievements in practice. Especially since the 1980s, the rapid development of modern biotechnology and its combination with traditional breeding techniques have promoted the development of traditional breeding at the molecular level. However, it is not realistic to use molecular biology technology as a means to assist traditional breeding to design excellent plant types. Therefore, the current research on high-yield crop breeding requires researchers to continuously ...
