中雨雪有利于农作物越冬
来源: 原阳新闻 发布时间: 2020-01-08

  俗话说:“冬有三白是丰年”,几场雨雪下来,对农作物越冬有着诸多影响,今天,我们的记者采访了县农业农村局高级农艺师——师学文,向广大农民朋友普及一下这场中雨雪天气对农业越冬都带来了哪些影响: 

  我县今年的小麦播种基础比较好,一是塲情充足,二是适播面积大。但是播种以后,到现在气温一直偏高,整个11月份到12月份两个月时间可以说是个暖冬年,全县小麦生长普遍比较旺盛,一类苗面积达到80%左右,是近年来最好的一年,但是入冬以来一直没有降雨,大部分麦田都呈干旱状态。综合来讲,就是麦苗生长的比较好,分蘖儿比较多,麦苗长得比较高,根系数量没有达到应有的标准。举个例子来讲,麦苗分蘖儿假如三到四个,但是地下根部只有两到三个,不是壮苗标准,是旺苗标准,这次雨雪基本上缓解了旱情,特别是对小麦根部生长起到了很好的促进作用。加之以后气温会降低,对上部增长起一定作用,也控制了旺长,对小麦越冬可以壮苗非常有利,也为明年的春季管理打下了很好的基础。

另外,有些群众打电话咨询,这次雨雪天气,能不能进行施肥?我家小麦长的非常不好,需不需要补施点肥料。在此提醒大家,确实底肥不足,麦苗较弱的地块儿,可以适当的使用速效氮肥、尿素等,每亩用510公斤,这样可以使麦苗有所转换,改善苗情,但是一定要注意,土壤湿度,可在土壤封冻以前施肥比较好,特别要注意的是气温下降到-5°以后,不要再施肥了,否则容易造成伤苗,造成肥害,可以等到春节以后麦苗返青时在进行补施肥料,这样效果会更好一点。

记者从县气象局了解到,预计未来12小时内,受降雪影响,我县路表温度低于0℃,将形成道路结冰。请广大市民做好防范准备,交通运输、公安等部门要按照职责分工做好道路结冰应对准备工作,驾驶人员要注意路况,安全行驶,行人外出要注意防滑。
