农业丰欠在很大程度上取决于人们对农业气候规律的正确认识和自觉运用。农业气候规律中,热量资源及其分配特点历来受到有关部门的高度重视。天府之国的四川盆地年平均气温为16—18℃,比同纬度的长江中下游高1—2℃,零度以上累计积温5900—6700℃,比长江中下游高400—500℃,素以热量丰
Much of the agricultural deficit depends largely on people’s correct understanding and conscious application of agricultural climate laws. In the law of agricultural climate, the characteristics of heat resources and their distribution have always been highly valued by relevant departments. The annual average temperature of the Sichuan Basin in the land of abundance is 16-18 ℃, which is 1-2 ℃ higher than that of the middle and lower reaches of the Yangtze River at the same latitude. The cumulative accumulated temperature above 59 ℃ is 5900-6700 ℃ and 400-500 ℃ higher than the middle and lower reaches of the Yangtze River.
