摘要
通过对吉林省中部地区九台、榆树、长春、德惠、永吉的水稻土主要养分状况进行的测定分析表明:各地N、P、K、Zn、有机质间均达到了极显著差异,总体表现为全Zn含量较高,K含量较低,其它元素含量中等。全K含量除九台外,均低于世界的平均水平;全Zn和有效Zn的含量差异较大.除永吉外,均高于或与我国度吉林省土壤全Zn含量持平,且全P和速效P及碱解N间、全Zn与速效K间呈显著正相关。表3,参9。
The analysis of the principal nutrients of paddy soil in the central regions of Jilin province (Jiutai, Yushu, Changehun, Dehui and Yongji)shows:the contents of N, P, K, Zn and organic matter in different areas varies greatly. In general, total Zn content is very high. K content is very low and others are at medium level. Except in Jiutai, total K content is lower than the average lew;l of the world. There is a significant difference between total Zn and effective Zn content. Except in Yongji, total Zn and effective Zn content are higher than or the same as total Zn content of China or Jinlin province. Total P, quick-acting P and alkaljhydrply zable N have a clear positive correlation. The same correlation exists between total Zn and quick-actingK.
