Experiments were carried out with citrus (Citrus reticulate) and tea (Podocarpus fleuryi Hickel.) to study the effects of compound fertilizers on their yields and quality. In the citrus experiment, application of compound fertilizers increased available P, K and Mg contents in soil but decreased alkali-hydrolyzable N contents in soil and N, P and K contents in leaves. In the tea experiment, application of compound fertilizers increased available P, K and Mg contents in soil and N, P, K and Mg contents in leaves but decreased alkali-hydrolyzable N in soil compared with the urea treatment. Application of compound fertilizers could improve the quality of citrus and tea, increase their yields and enhance their economical profits significantly. Compared with the control, application of compound fertilizers increased citrus yields by 6.31, 12.94 and 17.69 t/ha, and those of tea by 0.51, 0.86 and 1.30 t/ha, respectively. Correspondingly, profits were increased by 21.4% to 61.1% for citrus and by 10.0% to 15.7% for tea. Optimal rates of compound fertilizers were recommended for both crops.
以柑橘（Citrus reticulate）和茶树（Podocarpus fleuryi Hickel.）为试验材料，研究复合肥对其产量和品质的影响。在柑橘试验中，施用复合肥增加了土壤有效磷、钾、镁含量，但降低了土壤碱解氮含量以及叶片氮、磷、钾含量。在茶树试验中，与尿素处理相比，施用复合肥增加了土壤有效磷、钾、镁含量以及叶片氮、磷、钾、镁含量，但降低了土壤碱解氮含量。施用复合肥可改善柑橘和茶叶品质，显著提高其产量和经济效益。与对照相比，施用复合肥使柑橘产量分别提高了6.31、12.94和17.69吨/公顷，使茶叶产量分别提高了0.51、0.86和1.30吨/公顷。相应地，柑橘利润提高了21.4%至61.1%，茶叶利润提高了10.0%至15.7%。并推荐了两种作物的复合肥最佳施用量。
