对沈阳棕壤５年定位试验地各施肥处理土壤进行锌各形态系统分析。结果表明，覆膜栽培加剧了土壤各形态锌的消耗，多年施用氮素化肥使土壤交换态锌含量增加，施有机肥则增加了碳酸盐和专性吸附态、氧化态、有机态、残留态和全锌量。除残留态锌外，其它形态锌均随作物生长而减少，作物生育前期覆膜处理土壤有机态锌含量下降较快，而后期裸地土壤氧化态锌含量有回升趋势。土壤有机态锌是玉米吸收的主要形态。
The morphological analysis of various zinc fertilizers were conducted on the 5-year experimental plots of Shenyang brown soil. The results showed that film mulching aggravated the consumption of various forms of zinc in soils. After years of application of nitrogen fertilizers, the content of exchangeable zinc increased, while that of organic fertilizers increased the contents of carbonate and obligate adsorbed, oxidized, organic and residual State and the amount of zinc. In addition to the residual zinc, the other forms of zinc decreased with the crop growth, soil organic zinc content decreased rapidly in the early crop growth stage, while the zinc content in the bare soil increased. Soil organic zinc is the main form of corn absorption.
