摘　　要：【目的】研究硝酸盐对茄子种子发芽的影响,为提高茄子幼苗生产质量提供理论依据。【方法】采用不同浓度的4种硝酸盐,对茄子种子进行不同时间的处理,研究各处理对茄子种子萌发及根系的影响。【结果】硝酸钠(NaNO_3)、硝酸钙(ca(NO_3)_2)、硝酸钾(KNO_3)对茄子种子萌发均有不同程度的促进作用,而硝酸铵(NH_4NO_3)却有抑制效果。【结论】40mmoL/l Ca(NO_3)_26h处理在促进茄子种子快速萌发、整齐出苗、根系良好生长方面表现最佳。[ Objective ] To research the effect of nitrates on eggplant seed germination and provide a theo- retical basis for improving quality of eggplant seedling production. [ Method] Different concenlrations of four kinds of nitrates were used to handle eggplant seeds in different times and research their influences on eggplant seed germination and root system. [ Result] The sodium nitrate （ NaNO3 ）, calcium nitrate （ Ca （ NO3 ） 2 ）, potassium nitrate （KNO3 ） on eggplant seed germination had different degrees of roles, but ammonium nitrate （ NH4 NO3 ） exerted inhibitory effect. [ Conclusion ] The treatment of 40 tendency/l Ca （ NO3 ） 2 6 hours promoted the rapid germination of eggplant seeds, neat emergence and good performance in the root growth.
