The invention discloses a planting method capable of synchronizing safe planting and straw removal and remediation, and belongs to the field of planting and remediation of cadmium-contaminated rice soil. Calcium polypeptide is applied to cadmium-polluted rice soil to regulate and control rice plants not to generate yellow leaves and to be all dark green (which cannot be realized by the existing method), then the rice is planted in a super-dense manner, and the rice root system also reaches high density, so that the concentration of heavy metal cadmium ions absorbed by each rice plant is relatively reduced, and the rice yield is increased. Meanwhile, passivation competitive inhibition of calcium polypeptide is combined with resistance control, so that seeds are qualified, but straws still contain certain heavy metals; therefore, the purpose of removing and repairing cadmium-contaminated soil is achieved by collecting the straws and performing centralized treatment, namely, the planted seeds (edible parts) are qualified, and the yield of the cadmium-contaminated soil is improved. Synchronization of safe planting and straw removal remediation by using calcium polypeptide is realized,and a new remediation mode of cadmium-contaminated rice soil is established.
