摘要
在盆栽条件下 ,研究了 5 2个小麦品种的生物学产量及其地上部分钾积累量的差异 .结果表明 ,在供钾水平相同时 ,不同小麦品种的生物学产量及其钾积累量差异显著 ;不施钾条件下 ,钾积累量与生物学产量有极显著的相关关系 ;施钾条件下 ,钾积累量与生物学产量无显著的相关关系 .根据钾效应系数 (EC) ,将 5 2个小麦品种分成了
Soil culture experiment was conducted to study the difference in biomass and potassium accumulation among 52 wheat varieties under 2 level potassium conditions Results showed that ,the biomass and the potassium accumulation amount was significantly different among the varieties at the same potassium level On K 0 level ,the biomass was positively related to the potassium accumulation amount, while on K 1 level it was not so 52 wheat varieties were divided into 5 groups by effect coefficient
