In the 1950s, Chinese scientists also systematically studied the stage developmental theory of plants and conducted the analysis of the stage developmental characteristics of several major crops. The results have been widely used in cultivation and breeding practices, especially in Significant results have been achieved on wheat. However, due to the stage of development of the machine
