摘要
分析了作物产量与全生育期总腾发量之间线性与非线性关系产生的原因及其适用条件 ,给出了基于常规试验数据求解非线性关系的方法 ,为节水灌溉条件下的最优水管理提供了依据 。
The causes of producing linear and nonlinear relationship between crop yield and evaporotranspiration in whole growth period and their adaptive condition, are analyzed. Based on the conventional test data, a method for solving nonlinear relationship is given. It provides a basis of optimum water management for water saving. Finally, the analysis and calculation of an actual example are given. [
