			<p>当前，绝大部分麦田土壤墒情适宜，病虫草害总体较轻，仅零星出现锈病、红蜘蛛、蚜虫。但由于秋季雨水较多，<a href="https://www.llongyu.com/" target="_blank" rel="noopener noreferrer"><strong>粮食汽油播种机</strong></a>前作腾茬较晚、持续时间长，整地播种困难，播期差异大，早、中、晚播兼有之，生育进程不一，苗情复杂。坚持“促控结合、以促为主、分类管理”，根据不同区域和地块长势，因苗因地施策。<br />
一是控旺。<strong>粮食汽油播种机</strong>对播种较早、播量过大导致长势过旺的麦田，喷施生长延缓剂控制生育进程，注意不能过量，否则造成过度抑制。喷施生长延缓剂缺钾或播种时未施钾肥（或含钾复合肥）的麦田，可适量补施钾肥。<br />
二是促弱。对晚播弱苗以促为重点，适时追施拔节肥，适当提高追肥量，但全生育期亩施氮总量不得超过12公斤，过多施肥易造成倒伏风险。追肥应选择速效肥，有灌溉设施的地区可结合春灌进行，效果更佳。<br />
三是稳壮。粮食汽油播种机对播期、播量适宜的健苗麦田，按既定高产措施进行规范管理。拔节初期及时追施拔节肥（一般占总用肥量的30%—40%），墒情较差麦田要及时进行灌溉。<br />
四是降渍。清理沟渠，排湿降渍。麦子汽油播种机对旋耕整地麦田，水分下渗慢，渍害持续时间长，更要加强降渍管理。同时，适当追施速效氮肥，促进弱苗转化。如对旋耕麦田进行春灌，务必速灌速排，避免持水时间过长而加剧渍水危害。<br />
五是防病虫。<a href="https://www.llongyu.com/bozhongji/" target="_blank" rel="noopener noreferrer"><strong>粮食汽油播种机</strong></a>提示随着春季气温快速回升，病虫发展加快，务必加强病虫害尤其是条锈病的监测预防。小麦条锈病抗性较弱或抗性已退化又未进行包衣或药剂拌种的品种，常会先出现单叶（株）锈病，并快速发展成中心病团，应尽早处理和防治。同时，注意红蜘蛛、蚜虫的监测和预防。</p>
