The invention discloses a regulation and control method for enhancing
photosynthetic efficiency through
hormone signal transduction between grafted rootstocks and scions, and particularly relates to the field of
photosynthetic efficiency regulation and control. The regulation and control method comprises the steps that
hormone release data of rootstocks, photosynthetic response data of scions and corresponding time labels are obtained, and according to the
time difference between
hormone change and photosynthetic response, the photosynthetic response data of the scions are obtained; constructing a
state sequence with a
delay tag; and defining an action set according to the
delay characteristics marked in the
state sequence. By constructing a state transition structure of
delayed response perception and a regulation strategy generation
mechanism based on a time
recursion feature, an onset time point of a hormone
signal and a feedback response track of a scion are captured, and accurate identification and intervention opportunity optimization of a regulation window in a non-dominant
coupling chain are realized; therefore, the problems that an existing model cannot effectively model a
time evolution structure,
strategy execution is distorted, and improvement of
photosynthetic efficiency is difficult to stably capture are solved.
