font-family: Simsun; line-height: 24px; text-indent: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">　　一要：加強(qiáng)三類苗管理。三類苗應(yīng)抓住冬前未封凍的有利時(shí)機(jī)，管理，促根生長。要及時(shí)劃鋤松土，提高地溫。對于底墑較好的晚茬麥田，一般不澆冬水，以免降低地溫；對于底墑較差的晚茬麥，應(yīng)選晴天澆冬水，底肥不足的可施適量化肥。</span><br style="margin: 0px;
