| 摘 要： | ［目的］明确水稻种子萌发及幼苗生长期间硝酸镧溶液的最佳浓度和临界浓度。［方法］研究稀土元素镧对水稻萌发和幼苗生长的影响。［结果］20.0mg/L硝酸镧处理效果最佳。当浓度超过30.0mg/L时，种子萌发和幼苗生长受到抑制。［结论］稀土农用应该慎重，以确保农田生态系统的可持续利用。

| Abstract: | [Objective] The research aimed to study the optimum and critical concentration of La(NO3)3 solution during germination of the rice seed and the growth of the seedling.[Method] The effects of La3+ on germination of the rice seed and the growth of the seedling were studied.[Result] The optimal concentration of La3+ was 20.0 mg/L.When the La3+ concentration was higher than 30.0 mg/L,seed germination and seeding growth were depressed.[Conclusion] Lanthanon should be used carefully so as to ensure the sustainabl... |
