2019年辽宁秋收作物生长季气象条件及影响分析

分析2019年辽宁农业气象条件,为气象条件的对比分析和灾害影响研究提供参考。2019年辽宁秋收作物生长季内,农业气象条件为近5年最好,主要表现为旱田作物需水关键期水分条件较充足,成熟收获期农业气象条件利于作物籽粒继续增重。农业气象灾害种类多但对农业影响轻,主要农业气象灾害为局地渍涝和阶段性干旱,干旱影响为近5年最轻,病虫害影响轻。实地调查显示,主产区农业气象利于粮食作物丰收,辽西地区玉米产量潜力得以发挥,但各地大豆籽粒灌浆不充分。

The Effect and Evaluation of Agro-meteorological Condition during Growing Season of Autumn Grains in Liaoning Province in 2019

The agricultural meteorological conditions of Liaoning Province in2019 were analyzed,which could provide reference for the comparative analysis of meteorological conditions and the study of disaster impact. During the growing season of autumn harvest crops in Liaoning in 2019,the agro-meteorological conditions were the best in the past five years,mainly due to the sufficient water conditions in the critical period of water demand for dryland crops,and the agro-meteorological conditions during mature and pre-harvesting were conducive to continued grain filling. There were many types of agro-meteorological disasters,but their effects on agriculture were light.The main agro-meteorological disasters were local water logging and stage drought. The effect of drought was the lightest in the past five years. And the amounts and occurrence areas of pests and diseases were also small. Field survey showed that the agricultural meteorology in the main producing areas was conducive to the harvest of food crops,and the corn yield potential in western Liaoning had been exerted,but the grain weight of soybean was light.
