【摘要】 通过100mg/kg～400mg/kg不同稀土浓度对秋苦荞进行苗期处理,表明对生育时期和产量的影响差异均不显著。喷施稀土有降低株高的作用;分枝数以对照最高,达2.6个,其余各处理均有减少分枝的趋势,有随浓度的增大而增加的趋势。更多还原

【Abstract】 Based on studying the effects of the different rare earth concentration(100 mg/ kg ～ 400 mg/ kg)on the autumn buckwheat at seedling stage,the results indicated that rare earth spraying had no significant effect on growing period and yields.The plant height of spraying rare earth was decreased,and the branch numbers of the control were the highest (2.6 per plant) but other treatments were decreased which was enhanced with the increasing rare earth concentration.更多还原
