Crop yield increasing method

The invention discloses a rice yield increasing method which is characterized in that a pure traditional Chinese medicine yield increasing agent is used for processing seeds and plants before and after rice sowing, wherein the pure traditional Chinese medicine yield increasing agent is obtained by firstly adding alcohol to various bulk pharmaceutical chemicals for soaking, then adding the alcohol again, and then decocting and stewing the chemicals. According to the rice yield increasing method, the agronomic characters such as the maturing rate and the thousand seed weight of hybrid rice parents can be improved, and the yield of the hybrid rice is increased. Moreover, the rice yield increasing method has the greater advantages that filial generations of the hybrid rice are processed by adopting the method, the yield of next generations obtained by maturing of the filial generations sown as the seeds is not different from that of the filial generations, the rice yield is stable, the phenomenon that the filial
