style="visibility: visible;line-height: 2em;"> <span style="letter-spacing: 2px;font-size: 16px;"> 各镇（街道）要抓住早春晴好天气，积极组织发动，抓住有利时机进行田间杂草防除。</span></section><section style="visibility: visible;line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">1、从现在到小麦拔节前均为春季麦田化除的关键时期。<br style="visibility: visible;"/></span></section><section style="visibility: visible;line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">2、在此期间，应选择日均温度大于5℃的晴天中午用药，避开倒春寒及阴雨天。</span></section><section style="visibility: visible;line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">3、以罔草、节节麦、看麦娘等为主的禾本科杂草，可选用唑啉草酯、炔草酸、甲基二磺隆、啶磺草胺等单剂或复配剂进行防除；以猪殃殃、播娘蒿、繁缕等为主的阔叶杂草，可选用氯氟比氧乙酸、2甲4氯钠、双氟磺草胺等单剂或复配剂进行防除；混生田块可以选择组合用药。</span></section><section style="visibility: visible;line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">4、禁止使用长残留除草剂，以免对下茬作物造成药害。</span></section><section style="visibility: visible;line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">5、由于现在田间小麦群体大且杂草密度较高，施药时一定要用足水量，每亩不得低于60斤水。</span></section></section></section></section></section><section style="text-align: center;line-height:

<span style="letter-spacing: 2px;font-size: 16px;"> 返青拔节初期是纹枯病、茎基腐病、麦蜘蛛等病虫防控的关键时期，为提高防效，一定要把握好时间节点，采取有力措施科学开展防治。</span></section><section style="line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">1、农业防治：加强健身栽培，增施磷钾肥，提高小麦自身抗病能力。</span></section><section style="line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;">2、药剂防治：建议选用噻呋酰胺、戊唑醇、井冈霉素、丙环唑、氟环唑等单剂及其复配制剂。对重发田块，第一次防治结束后7-10天进行第二次防治。</span></section><section style="line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;"> 在做好病害防治的同时加入阿维菌素、联苯菊酯等防控麦蜘蛛，加入磷酸二氢钾、芸苔素、能百旺等植物生长调节剂，实现一次施药达到防病治虫、促苗转壮的效果。</span></section></section></section></section></section></p><p style="text-align: center;"></p><p><section style="text-align:

style="line-height: 2em;"><span style="letter-spacing: 2px;font-size: 16px;"> 对基肥用量不足、冻害偏重、叶片明显落黄或群体茎蘖数明显不足的田块，尽早适量追施返青肥促进弱苗转化，追肥量控制在每亩尿素10～15斤。</span></section><section style="line-height:
