微量元素在浙江柚产地的应用研究

作者在柚产地的农业科技人员的协助下．通过对柚类产量、品质与地质背景的相关性研究，经产地基岩、土壤与果树化学特征相关关系的调查与分析对比，发现各产地土壤成分所含元素丰度不一致。指出玉环地区微量元素含量较丰富，基本上满足柚生长的的需要；苍南地区MO、B元素含量较少；常山地区Zn、B元素含量少。为促进柚类产品产量，品质改善，应针对各产地欠缺元素的含量，专门配制除N、P、K含量较高肥料外，还需添加欠缺元素含量的复合肥。

APPLICATION OF ERACE ELEMENTS IN THE POMELO GROWING AREAS OF ZHEJIANG PROVINCE

Based on te investigation of the geological background conditions in the pomelo growing areas of Zhejiang, the author studied the trace element contents of rocks, soil and pomele plants in these areas and found that the rocks had great in different pomelo growing areas. In Yuhuan,the trace element contents are enough for pomelo growing; in Cangnan, elements Mo and B are lacked: and in Changshan, elements B and Zn are not sufficient. Experimentq that add trace elements to those needed have been done and progresses have been made.
