作物营养器官形态与产量相关性的研究,对于作物形态学、形态生理学、育种学、栽培学等许多学科,都有着十分重要的意义。这方面工作,早就引起人们的广泛注意。公元前三世纪《吕氏春秋》中就有关于稻的长相的记载。玉米在我国栽培较晚,但早在1760年的《三农记》中就有苗之壮弱与产量相关从而确定留苗技术的论述。近年以来,随着生物学的进展,作物器官建成观律的研究日益深入。一九六二年,李伯航等根据玉米器官形成规律提出不同时期器官建或中心和从属关系、任其云根据玉米器官建成的顺序性提出不同时期的供长中心、朱光焕发表株高穗位高等和产
Crop vegetative organ morphology and yield related research, for crop morphology, morphological physiology, breeding, cultivation and many other disciplines, are of great significance. Work in this area has long aroused people’s attention. In the third century BC, “Lu’s Spring and Autumn” there is a record of the appearance of rice. Corn cultivation in China later, but as early as 1760 in the “San Nongji” there is the weakness of seedlings and yield-related to determine Liao Miao technology discussion. In recent years, with the progress of biology, the research on the law of crop organs has become more and more in-depth. In 1962, Li Bohang put forward organs or centers and affiliations at different periods according to the formation of corn organs. Ren Qiyun proposed long-term centers for different periods according to the order of corn organs. Zhu Guanghuan published the report of the high ear height and yield
