摘要
对云南省耿马县蔗区耕作层土壤养分的测定表明,该县土壤的有机质含量为中等,氮素营养中上,钾素供给中下,磷素供给中下。各村片差别较大,部分土壤养分严重缺乏,土壤明显酸化。土壤主要养分的供给总体上处于中下水平。根据该蔗区土壤养分状况提出相应对策。
A soil monitoring on the cane fields of Gengma County of Yunnan Province was conducted in 2001. It revealed that the contents of organic-substance and nitrogen in the soil fell in the middle level, and that of potassium was universally low. Phosphorus was very deficient and the situation was becoming even worse. Soil was acid and the acidity was increasing. The supplies of the nutrients were poor on the whole. Some measures were presented accordingly.
