網路上估狗搜尋自製NPK液肥
相信很多人的都是
硝酸鉀KNO3 : 20g
磷酸氫二鉀K2HPO4 : 10g
溶於300mL的水
水草缸建議的濃度是
NO3 : 10~20ppm
PO4 : 0.5~2ppm
K : 10~20ppm
著上面的配方
20L每天加1mL可得
NO3: 2.045ppm
PO4: 0.909ppm
K: 2.037ppm
驗算:
K:39 P:31 N:12 O:16 H:1
NO3濃度:
KNO3式量: 39+12+16*3=101
60/101*20 / 1000000=11.88ppm
1mL->20L
1mL*11.88ppm=X*20000
X=0.0005ppm
跟上述1mL可得2.045ppm
建議濃度都差得太遠了......
請問哪邊錯了...
後面也會繼續算,但想先知道問題在哪。
