小麥種子在曬種、播種前，選晴天將小麥種子攤在席子上，厚度以5~7厘米為宜，連續暴曬2~3天，直到牙咬種子發響為止。
曬種(zhong)(zhong)時(shi)要(yao)經(jing)常翻動，使種(zhong)(zhong)子吸熱均勻，改善種(zhong)(zhong)皮的通(tong)氣性(xing)，增強(qiang)種(zhong)(zhong)子活力，提高種(zhong)(zhong)子發芽(ya)(ya)率(lv)。注(zhu)意千萬不(bu)要(yao)在水泥地、鐵板、石板和瀝青路面(mian)等上面(mian)曬種(zhong)(zhong)，防(fang)止高溫燙(tang)傷種(zhong)(zhong)子，降低了(le)發芽(ya)(ya)率(lv)。曬種(zhong)(zhong)后要(yao)注(zhu)意測定(ding)發芽(ya)(ya)率(lv)，以便確定(ding)播種(zhong)(zhong)量為了(le)后期更好(hao)的收獲。
