摘    要:在盆栽条件下,研究了52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52个小麦品种分成了5组。

关 键 词:施肥  小麦  品种  钾素积累差异  钾肥施用  产量效应

Abstract: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
Keywords:wheat  variety  potassium  accumulation  biomass  utilization efficiency of potassium
