摘　　要：试验于１９８９～１９９１年在江苏省农科院进行。供试水稻品种有：南京１４（籼）、０２４－２８（粳）、汕优６３（杂交籼稻）、亚优２号（亚种杂交），锌肥种类有：ＺｎＣｌ２、ＺｎＳＯ４和ＺｎＯ．采用不同种类、不同浓度的锌肥对水稻进行盆栽试验。结果表明：（１）水稻对锌的忍耐程度极高，与不同品种内在的生物学特性有关；（２）锌肥中锌对水稻的毒害较低，其对水稻的危害程度取决于锌肥中阴离子种类。The experiments were carried out in Jiangsu Academy of Agricultural Sciences (Nanjing) during 1989～1991. using four rice verieties: Nanjing 14. 024-28, Shanyou 63 and Yayou No. 2. The rice was cultured in pot with different kinds of zinc fertilizers (ZnCl2.ZnSO4. ZnO) and different levels. The results were as follows: 1. the tolerance degree with zinc of rice is extremely high, it has relation to internal biological characteristic of different rice varieties, 2. the harmful degree to rice of zinc in zinc fertilizer is lower. Its harmful degree to rice depends on the kind of negative iron in zinc fertilizer.
