摘要
脐橙已成为信丰县的支柱产业。通过对信丰县脐橙种植区成土母岩特征、农业地球化学特征、脐橙品种特性等方面的综合分析,得出结论:地质背景以花岗岩母岩区最佳,次为红层母岩区;脐橙品质和产量以纽贺尔最佳,朋娜次之;为满足脐橙生长的需要,要注意加施K肥、P肥及含有Ca元素的肥料,土壤中K、Ca、P、Mg、Fe、Cu、Zn等营养元素其有效态必须获得补充。
Planting orange has become the principal industry of Xinfeng County in Jiangxi Province.Based on the synthetical analysis of the features of weathered parent rocks and agricultural geochemistry and variety of oranges in Xinfeng County,it is concluded that the parent rocks of granite is the best geological background,and the second is the parent rocks of red beds for planting oranges.The type of best quality and quantity of orange is Niuhe'er,and the second is Pengna.It is need to fertilize K,P and Ca for orange growing.The nutrient elements of K、Ca、P、Mg、Fe、Cu、Zn in soil must be supplemented.
