摘要
文中在计算气候生产力的基础上 ,将粮食产量分离成经济技术产量和气象产量。并利用化肥施用量、一季稻种植面积百分率和 1～ 3月份平均温度分别建立它们的预测模型。此方法计算简单、预测时效长、准确率较高 。
Based on calculating climate productivity, the food output per unit area is separated into economic and technological yield and meteorological yield in this paper. The models for predicting them are established by using factors such as amounts of applied fertilizer.percentage of single harvest rice planting area and mean temperature from January to March.Because of its long effective period , high accuracy and simplicity to dalculate, this method has a wide using prospect in operational service.
