生產上應先曬種1～3天，選種後開始浸種。一般正常溫度條件下浸種48小時
，溫度偏低時浸種60xiaoshi。duiyujichayangdeshuidaozhongzihuoyiganbingpinzhongzhongzi，jinzhongshi，yingshidangtigaonongdu。jiangdiwenducuiyahuojinzhongbucuiyabozhong，nengzaiyidingchengdushangjianqingshuidaoemiaobingfasheng。buyongbingdaocaozuozhongzicuiyashidefugaiwu，jizhonggaowenduiouhuoshaohuibingdaocao，keyijianshaoshuidaoemiaobingjunyuan。
