摘  要:
为了明确平衡施肥对土壤养分状况的影响,应用土壤养分状况系统研究法,研究江西省樟树市的油茶林平衡施肥前后的土壤养分状况。结果表明:油茶林未施肥土壤主要养分限制因子根据亏缺严重程度由高到低排序依次为:Ca、N、P、Mo、K、B、Mg、Cu;平衡施肥后,油茶林土壤主要养分限制因子根据亏缺严重程度由高到低排序依次为:Ca、N、P、Mg、B。通过试验,可以看出合理施肥对于土壤养分状况的改善是具有明显效果的。

摘  要:
In order to make clear of effects of balanced fertilization on soil nutrient status, using soil nutrient status systematic approach, soil nutrient status before and after balanced fertilization was researched in Camellia oleiferaforests in Zhangshu City of Jiangxi Province. The results showed that: based on deficiency degree from high to low, the order of major soil nutrient limiting factors in C. oleifera forests was Ca, N, P, Mo, K, B, Mg, Cu in soil, before balanced fertilization, and it was Ca, N, P, Mg, B in soil after balanced fertilization. Therefore, the rational fertilization could improve the soil nutrient status effectively.
