padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 1、今年秋播时土壤墒情好，杂草发生较早较重类型复杂，主要有野燕麦、节节麦、播娘蒿以及玉米苗等。部分田块地下害虫危害较重，有麦苗发黄死苗现象。</span></section><section style="margin: 0px;

padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 2、今年小麦播种后无有效降雨，麦田表墒不足，部分苗田出苗不齐，出现掉根形成弱苗。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif;

outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif;

padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 今年的墒情充足，苗情复杂，有利有弊。小麦越冬期管理重点是促弱转壮、增加分蘖，培育壮苗，提高小麦抗寒性，为小麦安全越冬和明年丰产丰收打下基础，赢得主动。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif; font-size: 14px; letter-spacing: 2px; text-align: justify; white-space: normal; background-color: rgb(255, 255, 255); line-height: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 1、冬前镇压。对群体偏大，播种过早有旺长趋势的地块以及耕种粗放，秸秆还田土壤悬松地块冬前要镇压，防止冬季冻害死苗。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif; font-size: 14px; letter-spacing: 2px; text-align: justify; white-space: normal; background-color: rgb(255, 255, 255); line-height: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 2、预防稠旺苗。今年部分田块因早播，要注意防止稠旺苗出现。根据情况，在冬前一般亩用15%多效唑可湿性粉剂30—40克或壮丰安30—40毫升兑水25—30公斤进行叶面均匀喷施，控制生长，预防倒伏，并做到不重喷，不漏喷。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif; font-size: 14px; letter-spacing: 2px; text-align: justify; white-space: normal; background-color: rgb(255, 255, 255); line-height: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 3、促弱转壮。对三类麦田、弱苗田及播种过晚田块，管理以促为主，加强肥水供给，促弱转壮。对部分出苗较差田块，可采用小水漫灌或微喷灌等方式进行灌水，确保出苗。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif;

padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 4、适时冬灌。水地秸秆还田的麦田应适时冬灌，踏实土壤，防止掉根，预防冻害，促进小麦盘根分蘖，苗情升级转化。要在日平均温度稳定在3—5℃时冬灌，当气温低于0℃时要停止夜间灌水。冬灌时间在11月中下旬—12月中下旬。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif; font-size: 14px; letter-spacing: 2px; text-align: justify; white-space: normal; background-color: rgb(255, 255, 255); line-height: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; font-family: 宋体; font-size: 17px;"> 5、合理追肥。根据苗情实际。旱地麦田应结合降水进行，灌区麦田结合冬灌适时追肥。地力差、施肥不足、群体偏小，长势较差的弱苗麦田，建议亩追速效氮肥10-15公斤，一般田块亩追施7-10公斤，以促进生长。</span></section><section style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; color: rgb(50, 50, 50); font-family: system-ui, -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif; font-size: 14px; letter-spacing: 2px; text-align: justify; white-space: normal; background-color: rgb(255, 255, 255); line-height: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;"><span style="margin: 0px;
