GROWTH STAGE DETERMINATION SYSTEM AND METHOD

摘要

A method for in-season crop growth stage determination for crops within a geographic region, the method including: determining a measurement value for a physical geographic region (e.g., a crop field) for a time point based on remote information, determining a transition date based on the measurement value, determining the growth phase for the crops based on the transition date, and determining the crop growth stage based on the growth phase and the environmental parameters for the physical geographic region.

1. A method for in-season crop growth stage determination for in-situ crops within a geographic region, the method comprising:
a) receiving an image of the geographic region, the image recorded at a first time during a growing season; b) extracting a vegetative performance value for the geographic region from the image; c) selecting a reference curve from a plurality of reference curves as a growth curve for the geographic region, based on the vegetative performance value; d) determining a transition date based on the growth curve; e) selecting a growth phase model based on a current date and the transition date, comprising:
in response to a current date preceding the transition date, selecting a vegetative model;in response to the current date exceeding the transition date, selecting a reproductive model; f) calculating an accumulated growing degree day estimate for the geographic region, based on past environmental parameter values over the growing season for the geographic region; and g) determining a growth stage for the crops within the geographic region based on the selected growth phase model and the accumulated growing degree day estimate.
