| 摘 要： | 探讨了小区域范围内土壤pH值与土壤主要肥力指标N、P、K有效态的关系,结果表明土壤pH值与土壤速效P含量呈极显著负相关,相关系数为-0.498;与土壤缓效K呈显著正相关,相关系数为0.352;与水解性N和速效K含量相关性不明显。

| Abstract: | This article discusses the relationship between soil pH value and the main indicators of soil fertility of the effective state of N, P, K in the range of small area. The results showd that Soil pH value showed significant negative correlation with available P, the correlation coefficient is - 0. 498, significant positive correlation with alleviate the effect of soil K,the correlation coefficient is 0. 352, and showed no correlation with alkali -hydrolyzale N and available K. |
