【摘要】 选同一山药品种在不同产地栽培,研究不同产地对山药N,P,K的吸收特点,分析不同生育时期的植株不同器官中N,P,K含量.结果表明,不同产地山药中N,P含量均以根茎膨大盛期前后最高;山药生长期内对N的吸收量最高,K次之,P最低;不同产地山药根茎对N,P,K的总吸收量最高,其次为叶、茎.更多还原

【Abstract】 The paper mainly deals with the characteristics of N,P,K absorption in different producing areas, and analysis on the contents of N, P and K in the different organs of the same variety plant, which was cultivated in different areas The results show that the content of N, P and K is the highest in the flower stage in the two producing areas;the absorbing quantity of N is the highest in the whole stage, that of K is higher, P is the lowest It is in the Rhizomaroot that the whole absorbing quantity of N,P,K is the highest in the whole stage, leaf is in the second,and stem is in the third更多还原
