摘要
作物的茎秆高度与直径受力学规律制约，欲使作物受风雨侵袭而不倒伏，其高度与半径的关系应在ｒ￣（２／３）～ｒ￣２之间。
The height and diameter of the stem of crops are regulated by laws of mechanics.If the stem is to stay in an erect position without lodging in face of heavy rain or strong wind ,the desirable rela-tion between its height and diameter should be in the range of r￣(2/3) to r￣2.
