土壤中对玉米生长的有效锌为:EXC—Zn>R_2O_3—Zn>>OM-Zn。种植玉米促进了土壤锌向RES-Zn和CA—Zn转化。施入的水溶态锌绝大部分转变为土壤各形态锌,其分布为CA—Zn>RES—Zn>OM—Zn>R_2O_3—Zn>EXC—Zn。
The available zinc for soil growth in corn is: EXC-Zn> R_2O_3-Zn >> OM-Zn. Planting of maize promoted the conversion of soil zinc to RES-Zn and CA-Zn. Most of the water-soluble zinc applied was transformed into various forms of zinc, which distributed in the order of CA-Zn> RES-Zn> OM-Zn> R_2O_3-Zn> EXC-Zn.
