(1) The trace elements (10 mg H3BO3, 11.19 mg MnSO4 · H2O, 124.6 mg ZnSO4
· 7H2O, 78.22 mg CuSO4 · 5H2O, and 10 mg MoO3) are dissolved in 100 ml
sterile distilled water and then stored in the refrigerator for up to
several months;
前几样都能溶，加了Mo后，一直有白色粉末（沉淀？）在烧杯底部，加温，延长时间都
不行。
(2) FeSO4 · 7H2O (100 mg) is dissolved in 10 ml sterile distilled water and
is stored in the refrigerator for up to several months;
这个还好
(3) All of the other ingredients including 4.0 g KH2PO4, 6.0 g Na2HPO4, 0. | b*****n
