温室盆栽条件下进行的研究结果表明,外加可溶性锌在土壤中的形态转化深受土壤物质组成和pH的影响。在石灰性土壤中可溶性锌以进入碳酸盐结合态为主;在近中性水稻土中以进入有机态为主;在酸性土壤中以交换态为主。基本趋势为:随土壤pH升高,进入交换态的比例降低,而进入铁、锰氧化物结合态的比例则相应增加。 The results of greenhouse pot experiments showed that the morphological transformation of soluble zinc in soils was strongly influenced by soil composition and pH. In calcareous soil, soluble zinc was mainly in the carbonate-bound state, mainly in the near-neutral paddy soil, and mainly in the acidic soil. The basic trend is as follows: with the increase of soil pH, the ratio of entering the exchangeable state decreases, while that of entering the iron and manganese oxides increases correspondingly.
