Abstract

The invention discloses a crop-stem-diameter growth velocity predicting method based on the physiological effect. The crop-stem-diameter growth velocity predicting method includes the steps that as the relationships between the crop-stem-diameter growth velocity and air temperature and illumination intensity are researched, a crop-stem-diameter growth velocity predicting model based on the physiological effect is built with a linear regression method, and the crop-stem-diameter growth velocity is accurately predicted. By means of the crop-stem-diameter growth velocity predicting method, the growth condition of crops can be learnt in time, the growth and development stage of crops can be more accurately judged, a theoretical foundation and decision supporting are provided for reasonably arranging facility agricultural production and management, and the crop-stem-diameter growth velocity predicting method can be used for modern facility agriculture environment control.

Description

technical field [0001] The invention belongs to the technical field of facility agricultural environment control, and in particular relates to a method for predicting the growth rate of crop stem diameter based on physiological effects. Background technique [0002] In the vegetative growth period of crops, the generation and transportation of dry matter are closely related to environmental conditions, and the dry matter allocated to the stem is mainly used for the growth changes of crop height and stem diameter, so the growth change of crop stem diameter is closely related to the environment conditions are closely related. Stem diameter can well reflect the growth state of crops, for example, slight changes in stem diameter can reflect the water status of crops. Therefore, it is of great significance to accurately predict the dynamic change of stem diameter to understand the growth status of plants in time. [0003] At present, the growth change of crop stem diameter is m...
