2006年宜良县土壤养分调查结果表明:全县耕地土壤有机质、全氮、碱解氮、速效磷、速效钾含量分别为32.41g kg-1、1.77 g kg-1、128.4 mg kg-1、35.5 mg kg-1、161.7 mg kg-1,与1980年相比较,水稻土有机质、速效磷、速效钾含量分别增加了1.61 g kg-1、13.0 mg kg-1、87.0 mg kg-1,旱地土分别增加了3.75 g kg-1、21.3 mg kg-1、162.8 mg kg-1。然而,汤池镇、耿家营乡和竹山乡的水稻土有机质含量,耿家营乡和狗街镇的旱地土有机质含量,南羊镇旱地土速效磷含量与1980年相比都发生了不同程度的减少。
The results of soil nutrient survey in Yiliang County in 2006 showed that the content of soil organic matter, total nitrogen, available nitrogen, available phosphorus and available potassium in cultivated land were 32.41g kg-1, 1.77g kg-1 and 128.4mg kg-1, 35.5 Compared with 1980, the contents of organic matter, available phosphorus and available potassium in paddy soil increased by 1.61 g kg-1 and 13.0 mg kg-1,87.0 mg kg-1, respectively, Increased 3.75 g kg-1, 21.3 mg kg-1 and 162.8 mg kg-1, respectively. However, the organic matter content of paddy soil in Tangchi, Gengjiaying and Zhushan, the content of organic matter in dryland in Gengjiaying and Goujie townships, and the content of available phosphorus in dryland soil in Nanyang town decreased compared with those in 1980.
