| 摘 要： | 为了全面掌握北京市昌平区优质、高产富士苹果园在杜绝施用化肥后土壤养分及矿质元素的变化情况,对土壤中7种有效的矿质元素N、P、K、Ca、Fe、Zn、Mn在不同时期含量的变化及其规律进行了研究。结果表明：该果园土壤有效N含量全年呈下降趋势,9月初为最低;有效P含量6月中旬至下旬大幅下降,8月下旬达到最低值;速效K含量6月中旬达到最低值;有效Ca含量8月中旬达到最低值;有效Fe、Zn、Mn含量7月下旬达到最低值。总体来看该果园土壤中有效N、Ca含量偏低,有效P、Zn和速效K含量在正常值范围内,有效Fe含量高于一般正常果园含量。

| Abstract: | In order to understand variation pattern of several mineral elements when stop using chemical fertilizers,the contents of available N,P,K,Ca,Fe,Zn,Mn in Red Fuji apple Orchard soils of high quality and yield in Changping district of Beijing were studied during different growth periods.The results showed that the contents of available N were declined,the lowest in the first ten-days in September.The contents of available P were declined,the lowest in August.The content of available K was the lowest in the mi... |
