摘要
为了研究平衡施肥对油茶林地土壤中氮、磷、钾和有机质含量等主要养分含量的影响情况,文中以"赣无"系列油茶为研究对象,采用双因素重复试验设计,分别在江西的九江基地和丰城基地进行了对比试验与测定分析。研究结果表明:九江基地平衡施肥区土壤中的氮、磷、钾和有机质含量比对照区分别提高了66%、47%、55%和45%;丰城基地平衡施肥区土壤氮、磷、钾和有机质含量比对照区分别提高了46%、56%、49%和59%。试验结果说明了平衡施肥比常规施肥能更有效地提高土壤中氮、磷、钾和有机质的含量,改良土壤肥力。
In order to study effects of balanced fertilization on main soil nutrient content indexes in Camellia oleifera forest, the Ganwu series in C. oleifera were taken as the research objects, using two-factor repeated experimental design, the contents of N, P, K and organic matter were measured and compared in Jiujiang and Fengcheng bases of Jiangxi Province. The results show that, compared with the control, the contents of N, P, K and organic matter in soil are increased by 66%, 47%, 55% and 45% at the balanced fertilization area in Jiujiang, and they are increased by 46%, 56%, 49%, and 59% at the balanced fertilization area in Fengcheng. So balanced fertilization can more effectively improve the contents of N, P, K and organic matter in soil and improve soil fertility compared with conventional fertilization.
