摘  要:
通过对防城港市防城区1980年第二次全国土壤普查、1998年配方施肥养分测定和2007年国家立项测土配方施肥项目耕地土壤养分测定结果分析,及对20多年来施肥量的比较,研究肥料施用和耕地土壤养分变化情况。结果表明,防城区耕地土壤养分变化较大,有机质、全氮、速效磷含量总体上呈上升趋势,但土壤养分含量极不平衡,必须重视用地养地,平衡施肥。

摘  要:
Through the results analysis of second national soil census in 1980,soil nutrients test in 1998 and 2007,and the comparison of fertilization amounts during past two decades,the fertilization and soil nutrient change were researched.The study results show that there was a big change in farmland nutrients,general speaking,organic matter,total N and quick-acting P’s contents were increasing,but the nutrients imbalance was seen so that it is necessary to pay more attention to soil nutrient maintaining and equilibrium fertilization.
