摘要: 在北京地区,对京早1号等7个品种谷子的氮及灰分元素含量、存留量、生物吸收系列以及消耗系数进行了研究,结果表明:①不同品种对同一元素吸收能力不同;②7个品种元素生物吸收系列都属于 Si—N 型;③7个品种地上部分存留量平均值呈如下顺序:Si>N>K>Mg>Ca>P;④不同品种消耗系数可分为高、中、低三种类型。

Abstract: The content and retention of N and ash elements,bioabsorbed seriesand consume coefficient in 7 millet varieties were studied in Beijingdistrict.Results showed as follows:1.The absorbability in the uptake of elements varied with varieties;2.The bioabsorbed series of the 7 varieties all belong to Si-N
