天津市2018年秋季农业气象条件分析
|
摘要
根据天津市13个气象站的观测资料,总结2018年秋季天津气温、降水、日照3个主要气象要素的变化趋势和特点,分析了秋季气象条件对主要农作物的影响。结果认为:秋季农业气象条件总体为"气温略偏高,日照充足,降水偏少"。冬小麦播种期表墒差导致发育期较历年偏晚,后期多次降水有效补充了土壤水分,冬小麦苗情长势较好。季内设施生产未出现连阴寡照气象灾害,设施蔬菜长势正常。秋季气象条件对农业生产总体比较有利,并根据冬季气候预测提出相应的农事生产建议。
According to the observation data of 13 fixed weather stations in Tianjin, summarized the trends and characteristics of the three major meteorological elements that temperature, precipitation and sunshine in Tianjin during the autumn of 2018, analyzed the impact of autumn meteorological conditions on the main crops. The results showed that the temperature was slightly higher than normal in autumn were "the sunshine was sufficient, and the precipitation was less than normal". The surface soil moisture of the winter wheat was poor during the sowing period, resulting in a later growth period than the previous years. After the sowing period, multiple precipitations could effectively replenish soil moisture, and the current winter wheat grew better. No severe meteorological disasters occurred in autumn, and the facilities vegetables were growing normal. Autumn meteorological conditions were generally favorable to agricultural production. Then we put forward the corresponding agricultural production suggestions according to the winter climate prediction.
