摘要
本文对浙江湖州地区土壤营养元素氮、磷、钾的全量和有效态含量分布状况作了详细介绍,在此基础上评价了土壤营养元素的丰缺特点,认为湖州地区土壤中营养元素氮含量大多在丰富级-极丰富级之间,基本无需施加氮肥;磷和钾有近三分之一区域处于缺乏状态,近三分之一区域处于中等偏下状态,应视情作及时增补。
Distribution of the total quantities and effective quantities of soil nutrient elements(N,P,K)in Huzhou area of Zhejiang province was in detail introduced in this article, furthermore, abundant or lack characteristics of soil nutrient elements were appraised. The authors suggested that the contents of soil nutrient element N in the most part of Huzhou area were from abundance to extreme abundance, therefore it was not necessary to fertilize with nitrogen fertilizer in the area; while it was necessary to fertilize with phosphorus and kalium, because the area,which was lack of nutrient element P and K, covered one third of Huzhou area,and one third of the area contained these elements with middle to low contents.
