1. 根據(jù)元素的mg/L數(shù)按比例計(jì)算法 中國(guó)苗木網(wǎng),999miaomu.com
首先從需要量較大的鈣開始計(jì)算，然后再計(jì)算與硝酸鈣有關(guān)的其他元素，一般是計(jì)算氮，然后計(jì)算磷、鉀，最后計(jì)算鎂，因?yàn)殒V化合物與其他元素不相互影響。 苗木網(wǎng),www.cqhuayin.com
配方中鈣的濃度為每升水含180mg鈣，如果用Ca(NO3) 2作為鈣鹽，Ca(NO3) 2的分子量為164，而在164mg硝酸鈣中含有40mg鈣。按比例法計(jì)算為： 苗木網(wǎng),www.cqhuayin.com
40:164=180:X X=(164×180)/40=738 (mg/L 中國(guó)苗木網(wǎng),www.cqhuayin.com
∵ Ca(NO3) 2的純度為90% 中國(guó)苗木網(wǎng),999miaomu.com
∴Ca(NO3) 2的實(shí)際用量為： 738mg÷90%=820 (mg/L) 中國(guó)苗木網(wǎng),999miaomu.com
然后計(jì)算820mg硝酸鈣中的能提供的氮素量含量，以此類推就可以計(jì)算出配方中各種元素相應(yīng)的化合物的用量。結(jié)果為： 999中國(guó)苗木網(wǎng),www.cqhuayin.com
Ca(NO3) 2 820 mg/L K2SO4 290 mg/L 999中國(guó)苗木網(wǎng),www.cqhuayin.com
KNO3 319 mg/L MgSO4 526 mg/L 999苗木網(wǎng),www.cqhuayin.com
KH2PO4 139 mg/L 999中國(guó)苗木網(wǎng),999miaomu.com
2.配方計(jì)算方法 999苗木網(wǎng),www.cqhuayin.com
與按比例計(jì)算的原理相同，只是先計(jì)算1mg/L元素所需化合物的量，然后乘以配方中各元素的量，既為所需元素相應(yīng)的化合物的用量。還可將計(jì)算好的1mg/L元素所需化合物的用量列表，然后查表計(jì)算。 苗木網(wǎng),999miaomu.com
