水稻生產即將進入播種育苗季節，湖北華苑糧油小編科學掌握浸種時間和方法是提高水稻發芽率、培育壯秧的關鍵。

曬(shai)種(zhong)(zhong)。谷子(zi)種(zhong)(zhong)籽(zi)(zi)浸種(zhong)(zhong)前需(xu)確定晴(qing)天(tian)氣(qi)晴(qing)朗預(yu)告曬(shai)種(zhong)(zhong)2—3天(tian)，以便(bian)于挺高(gao)谷子(zi)種(zhong)(zhong)籽(zi)(zi)的出(chu)芽勢和出(chu)芽率。但(dan)要特(te)別(bie)留(liu)意不能把稻種(zhong)(zhong)攤在水泥沙復合地板或青(qing)石(shi)上曬(shai)，預(yu)防(fang)皮膚(fu)曬(shai)紅種(zhong)(zhong)籽(zi)(zi)。在烘(hong)干的環節過程(cheng)中應特(te)別(bie)留(liu)意勤翻動。

茶水(shui)選(xuan)(xuan)種(zhong)。選(xuan)(xuan)種(zhong)時，茶水(shui)的(de)比重(zhong)怎么算應(ying)完成1.13(25多斤重(zhong)海(hai)里，熔化5多斤重(zhong)鹽)。茶水(shui)選(xuan)(xuan)種(zhong)后一定的(de)要裝干(gan)凈(jing)的(de)水(shui)洗三次(ci)，說(shuo)真的(de)原材料就沒法出芽。

迅(xun)雷(lei)鏈接(jie)bt紫(zi)(zi)外線(xian)(xian)紫(zi)(zi)外線(xian)(xian)消毒(du)及浸(jin)種(zhong)。把(ba)選擇好(hao)的迅(xun)雷(lei)鏈接(jie)bt用25%施保克(咪酰胺)每袋(dai)(10毫克)對水50斤重(zhong)，浸(jin)種(zhong)40斤重(zhong)，水溫表保持(chi)穩定在11～12℃,浸(jin)種(zhong)紫(zi)(zi)外線(xian)(xian)紫(zi)(zi)外線(xian)(xian)消毒(du)6～7天。重(zhong)視(shi)浸(jin)種(zhong)時，水應超出(chu)稻(dao)種(zhong)10cm上文(wen)，積溫要滿足(zu)100度，經常翻(fan)動單次。

催(cui)(cui)(cui)芽(ya)。將浸好的(de)種子取(qu)出用紗(sha)網袋催(cui)(cui)(cui)芽(ya)。稻(dao)種不斷升溫(wen)(wen)后(hou)(hou)，氣(qi)溫(wen)(wen)管(guan)控(kong)(kong)在30～32℃，氣(qi)溫(wen)(wen)過高(gao)要(yao)翻堆，露白后(hou)(hou)氣(qi)溫(wen)(wen)管(guan)控(kong)(kong)在25℃。催(cui)(cui)(cui)芽(ya)時(shi)要(yao)立刻注意事項稻(dao)種氣(qi)溫(wen)(wen)的(de)的(de)變化(hua)，適溫(wen)(wen)催(cui)(cui)(cui)芽(ya)，芽(ya)根(gen)各(ge)長以2mm毫(hao)米三歲為宜，催(cui)(cui)(cui)好后(hou)(hou)在陰暗處處晾芽(ya)，處理秋播。

平攤曬芽

在催芽(ya)(ya)成功失敗后，要(yao)為能(neng)讓讓種(zhong)(zhong)(zhong)籽(zi)(zi)地(di)址可能(neng)積(ji)極的(de)應(ying)用栽植(zhi)攝氏度等自(zi)然規律生(sheng)態(tai)(tai)學(xue)習壞(huai)境，人(ren)們還需(xu)求重(zhong)復(fu)實行曬種(zhong)(zhong)(zhong)工做(zuo)。這件事(shi)曬種(zhong)(zhong)(zhong)主要(yao)的(de)是要(yao)為能(neng)讓增強學(xue)習芽(ya)(ya)的(de)應(ying)用本(ben)事(shi)。一般來說在催芽(ya)(ya)后將種(zhong)(zhong)(zhong)籽(zi)(zi)地(di)址平攤放到(dao)棚內翻曬12H以(yi)內，隨后再(zai)下種(zhong)(zhong)(zhong)。只要(yao)個別水稻種(zhong)(zhong)(zhong)植(zhi)種(zhong)(zhong)(zhong)籽(zi)(zi)地(di)址在催芽(ya)(ya)最后，鑒(jian)于地(di)溫等生(sheng)態(tai)(tai)學(xue)習壞(huai)境重(zhong)要(yao)因素(su)導至不可能(neng)當即(ji)下種(zhong)(zhong)(zhong)說的(de)話。也能(neng)當即(ji)曬芽(ya)(ya)，在降地(di)溫壞(huai)境濕度等操縱根芽(ya)(ya)的(de)種(zhong)(zhong)(zhong)子發芽(ya)(ya)，隨后等待生(sheng)態(tai)(tai)學(xue)習壞(huai)境舒(shu)適的(de)情況再(zai)下種(zhong)(zhong)(zhong)。
