Abstract: According to 13 meteorological stations in Tianjin, the characteristics and trend of temperature, sunshine and precipitation were analyzed and compared with the same period in history. Agro-meteorological conditions were analyzed and the conclusions are as below: Disastrous weather was not occurred during whole winter. Agro-meteorological conditions were positive. Winter wheat lived through the winter safety with green. The production of facility agriculture keeps normal. The suggestions of agricultural production were proposed at last.

2 2015年春季气候预测
春季内,3月平均气温略偏高,4月接近常年,5月略偏高。3月降水量略偏多,4月和5月略偏少。
3.1 设施农业
3.2 冬小麦
天津市冬小麦于12月初普遍进入越冬期,时间与常年基本一致,冬前积温为450~550 ℃左右,达到壮苗标准。麦田冬前普浇越冬水,足墒越冬。
4 2015年春季农事生产建议
(1)3月上旬天津市全市冬小麦将陆续返青,目前麦田表墒良好,气温平稳回升,利于冬小麦返青生长。小麦返青起身期仍需注意低温、干旱等气象灾害,及时浇灌,保证齐苗壮苗。
(2)春季冷空气活动频繁,提醒农户注意应对大风、连阴雨天气,保证设施农业生产安全。另外,进行春提前栽培生产的农户更需注意倒春寒影响。
(3)根据植保部门预计,今年天津市主要农作物病虫害呈中等至偏重发生。应加强田间病虫害的监测预警,做好控制病虫害发生发展的准备工作。
