栽培要點
1、播(bo)(bo)(bo)期和播(bo)(bo)(bo)量(liang)：10月(yue)5~20日播(bo)(bo)(bo)種，播(bo)(bo)(bo)期10月(yue)10日左右(you)；高(gao)肥力地塊每畝(mu)播(bo)(bo)(bo)量(liang)6~8kg，中低(di)肥力地塊每畝(mu)8-10kg，如(ru)延期播(bo)(bo)(bo)種，以(yi)每推遲3天畝(mu)播(bo)(bo)(bo)量(liang)增加0.5kg為宜。
2、田(tian)間管(guan)理：般(ban)畝施底(di)肥尿素20kg，磷酸—銨(an)25kg，硫酸鉀(jia)15kg或二(er)元素復合(he)肥（15： 15： 15)50kg，春節(jie)前后每畝追(zhui)施尿素7~ 10kg。拔節(jie)前進行(xing)化學除草(cao)，并適當(dang)澆灌返青水，灌漿期噴施磷酸二(er)氫鉀(jia)，結合(he)天氣情況(kuang)及時防治白粉病和小(xiao)麥穗蚜。
