| Abstract: | 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. |
