摘要
本文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。
In this paper, the relationship between soil pH value and the available state N, P, K in small area was discussed. The results showed that soil pH value appeared significantly negative correlation with readily available P and the correlation coefficient was -0. 498; positive correlation with slow releasing K and the correlation coefficiem was 0. 352; no significant correlation with hydrolytic N and readily available K.
