真空數粒置種儀與光電自動數粒儀的功能區分

在zai種zhong子zi檢jian驗yan過guo程cheng中zhong，我wo們men通tong常chang會hui使shi用yong到dao一yi些xie相xiang關guan的de儀yi器qi

，如ru種zhong子zi千qian粒li重zhong的de測ce定ding需xu要yao用yong到dao自zi動dong數shu粒li儀yi，種zhong子zi淨jing度du測ce定ding需xu要yao用yong到dao多duo功gong能neng種zhong子zi淨jing度du工gong作zuo台tai。那na麼me真zhen空kong數shu粒li置zhi種zhong儀yi是shi用yong於yu對dui種zhong子zi進jin行xing數shu粒li

、種子發芽率等參數的測定。

下麵我們具體就真空數粒置種儀和光電自動數粒儀的功能以及結構區別，作一分析。

真空數粒置種儀：zhenkongshulizhizhongyi
，ruguokantademingcheng，nijiuhuixiangdaozhekuanyiqishinenggoushuzhonghezhizhongde。deque，zhenkongshulizhizhongyizhuanmenyongyuzhongzifayashiyanguochengzhongdeshuzhong、吸種和置種用。但是其中的置種功能最為強大，它的原理是利用抽去空氣，進行吸種。一般的，每個置種盤是100個孔，發芽盒跟國際標準通用，一次能夠吸種100粒li，然ran後hou直zhi接jie放fang在zai發fa芽ya盒he中zhong，排pai放fang整zheng齊qi，省sheng去qu了le用yong鑷nie子zi一yi粒li粒li排pai放fang的de麻ma煩fan。大da大da提ti高gao了le種zhong子zi發fa芽ya的de效xiao率lv。因yin此ci
，真zhen空kong數shu粒li置zhi種zhong儀yi最zui主zhu要yao和he最zui關guan鍵jian的de功gong能neng是shi置zhi床chuang
，在zai發fa芽ya時shi應ying用yong最zui為wei方fang便bian。
光電自動數粒儀：光guang電dian自zi動dong數shu粒li儀yi是shi利li用yong光guang電dian轉zhuan換huan，將jiang種zhong子zi動dong能neng得de到dao的de光guang脈mai衝chong
，轉zhuan化hua為wei電dian壓ya的de高gao低di，再zai進jin行xing計ji數shu。一yi般ban在zai數shu粒li前qian我wo們men都dou需xu要yao預yu置zhi粒li子zi數shu，然ran後hou數shu粒li儀yi的de計ji數shu到dao達da預yu定ding的de數shu目mu時shi，儀yi器qi就jiu會hui自zi動dong停ting止zhi計ji數shu。光guang電dian自zi動dong數shu粒li儀yi最zui大da最zui關guan鍵jian的de功gong能neng是shi數shu粒li，因yin此ci在zai做zuo千qian粒li重zhong指zhi標biao最zui好hao。
