在土壤(山西土)中加入不同种类、不同浓度的硝化抑制剂(氢醌、硫脲、双氰胺), 研究了其对小麦发芽势、发芽率和幼苗生长的影响.结果表明: 双氰胺对小麦发芽势和发芽率的抑制作用不明显, 硫脲对小麦发芽势和发芽率有一定的抑制作用, 而氢醌对小麦发芽势和发芽率抑制明显; 双氰胺和氢醌对小麦幼苗生长的影响不大, 而硫脲能显著降低小麦幼苗的根长、茎长、根重和茎重; 双氰胺对小麦种子和幼苗毒性相对较小, 硫脲毒性相对较大, 小麦的根重、茎重和根伸长可以作为硫脲对小麦危害的敏感指标

Laboratory investigations were conducted to study the influence of three types of nitrification inhibitors（hydroquinone,thiourea and dicyandiamide）on seed germination and growth of wheat.Results showed that dicyandiamide had little effect on seed germination while thiourea inhibited the seed germination to a certain extent,and hydroquinone retarded the germination of wheat seeds significantly.The pot experiment indicated that hydroquinone and dicyandiamide had little influence on wheat growth while thiourea could reduce length and strength of...
