2022年秋季气象条件对农业生产的影响

2022年秋季（9-11月），全国平均气温10.9℃，为1961年以来同期最高；全国平均降水量107.5mm，较常年同期偏少8.5%；全国平均日照时数575.2h，接近常年同期。全国大部农区秋季光热条件较好，东北地区初霜期较常年偏早但持续时间短，南方晚稻区未出现大范围寒露风天气，气象条件总体利于秋收作物灌浆成熟、收晒和秋播，秋收秋种总体进展顺利。但是，江西、湖南和贵州东部等地农业干旱发生范围广、持续时间长，导致部分地区油菜播种出苗困难，部分在地作物及经济林果产量和品质也受到不利影响。

Impact Report of Meteorological Conditions on Agricultural Production in Autumn 2022

In autumn of 2022, the national average temperature was 10.9℃, which was the highest in the same period since 1961. The national average precipitation was 107.5mm, 8.5% less than the normal value. The national average sunshine duration was 575.2h, close to the same period of the normal years. The sunshine and temperature in most agricultural regions of China were suitable during autumn. The early frost in Northeast China occurred earlier than the normal years but its duration was shorter. There was no cold and dew wind in the late rice region. The meteorological conditions were generally favorable for crops grain-filling, maturing, harvesting, drying and autumn planting. The autumn harvest and sowing were generally progressing smoothly. The agricultural drought in Jiangxi, Hunan, eastern Guizhou and other regions occurred a wide spatial distribution and lasted for a long time, which resulted in difficulties for sowing and emergence of rape seedlings in some areas. So the yield and quality of some field crops and economic forests were also adversely affected.
