作物群体只有在合理的密度基础上才能获得最高产量,因而研究作物产量与密度的曲线方程是非常重要的。只有正确描写产量与密度相关关系的理论方程,才能正确预报合理密度,指导生产。
It is important to study the curvilinear equations of crop yield and density only if the crop population achieves the highest yield on a reasonable density basis. Only correctly describe the relationship between yield and density of the theoretical equation, in order to correctly forecast the reasonable density, guide the production.
