| 内容記述 | If long-term detailed weather forecasts were available prior to crop planting in warm periods, many advantages could be seen in paddy rice cultivation. In this paper, the gain in climatic productivity, mainly by determining the most suitable heading period, is discussed through using a climatic productivity model of paddy rice (Sugihara and Hanyu, 1980). This model of Y_p, assuming the most profitable selection of cultivating varieties, indicates the maximum yield under certain climatic conditions. For example, if a suitable heading period could have been applied to some of the areas that suffered damage in the coolest summer in recent years-1980, then roughly more than 10% of the decrease could have been save. In addition, the effect of a monthly decrease in mean air temperature of 2℃ in warm periods is also examined. Finally, the relationship between relative Y_p and relative crops in 1980 is discussed. | |||||||
