1. A method for rice growth based on the regulation during vegetative growth period of the rice, comprising
soaking seeds of the rice,
germination of the soaked seeds of the rice,
cultivation of the germinated soaked seeds of the rice,
managing and regulating of the rice at a growth stage, and
harvesting the rice, wherein the managing and regulating of the rice at the growth stage includes regulation of dynamic light quality and photoperiod environment during the vegetative growth period of the rice; wherein
the regulation of dynamic light quality and photoperiod environment during the vegetative growth period includes: cultivating under the conditions of mixed light source with the ratio of red light:blue light:white light of 0.8-1:0.8-1:1.0, photoperiod of 16-18 h and illumination intensity of 200-300 μmol m−2 s−1;
wherein the red light has a wavelength of 660 nm, the blue light has a wavelength of 450 nm, and the white light has a wavelength of 400-700 nm;
wherein the managing and regulating of the rice at the growth stage further comprises:
acquiring one or more historical growth parameters of at least one historical growth period of the seeds of the rice before a target growth period, wherein the target growth period is the vegetative growth period and the historical growth parameters at least include historical illumination parameters;
acquiring one or more preset illumination parameters, wherein the one or more preset illumination parameters include preset illumination time and preset illumination intensity;
for each of the one or more preset illumination parameters, according to the historical growth parameters of the at least one historical growth period and the preset illumination parameter, determining a predicted growth quality of the seeds of the rice in the vegetative growth period under the action of the preset illumination parameter based on an illumination prediction model; and
determining one or more target illumination parameters of the vegetative growth period according to the predicted growth quality corresponding to each of the one or more preset illumination parameters.
