2009年的雨雪冰冻灾害天气严重时可造成农业损失惨重,低温冻死一部分越冬虫害及虫卵,降低来年病虫害发展趋势,但造成了一部分冬小麦冻害和分蘖不足,苗情较差,对其产量基本无影响;降雪早致使未能及时收获的露地蔬菜受冻,积雪过重压塌损坏一部分蔬菜大棚和食用菌棚等设施,导致大棚蔬菜受冻,还造成牲畜、家禽圈舍倒塌,砸死砸伤家畜。因此,提高农业气象灾害认识,加强灾害性天气防御和应对,是促进农业生产发展的重要措施。
Severe rain and snow disasters in 2009 can cause heavy agricultural losses and freeze some of the overwintering pests and eggs at low temperatures to reduce the development trend of pests and diseases in the coming year. However, some winter wheat frost damage and tillering problems are caused and the seedling condition is poor. Basically no effect; snowfall as a result of early harvest of vegetables can not be frozen in the open field, snow collapse overcrops damaged part of the vegetable sheds and edible fungus shed and other facilities, resulting in greenhouse vegetable freezing, but also caused livestock and poultry houses collapsed, smashed Deadly hurt livestock. Therefore, raising awareness of agrometeorological disasters and strengthening disastrous weather defense and response are important measures to promote the development of agricultural production.
