摘　　要：对鄂茶1号、鄂茶10号和中茶108茶树品种分别进行复合肥(N∶P_(2)O_(5)∶K_(2)O=15%∶15%∶15%)、叶用经济作物专用肥(N∶P_(2)O_(5)∶K_(2)O=17%∶5%∶25%)和配方施肥(N∶P_(2)O_(5)∶K_(2)O=18%∶6%∶12%)3种施肥处理,分析了各处理对幼龄茶树萌芽数、主茎直径和生长势的影响。结果表明,各施肥处理均显著提升了3个品种幼龄茶树的萌芽数、主茎直径和生长势,其中复合肥处理提升效果显著高于其他施肥处理。基于研究结果,推荐复合肥处理作为幼龄茶树的施肥方案。In this study,three fertilizer treatments,including compound fertilizer(N∶P_(2)O_(5)∶K_(2)O=15%∶15%∶15%),special fertilizer for leaf-usage cash crop(N∶P_(2)O_(5)∶K_(2)O=17%∶5%∶25%),formula fertilizer(N∶P_(2)O_(5)∶K_(2)O=18%∶6%∶12%)and the control(CK)were compared in the three tea cultivars'seedlings(Echa 1,Echa 10,Zhongcha 108)to reveal their effects on plant growth,bud number and main stem diameter.The results show that the bud number and main stem diameter of three tea cultivars under the fertilizer treatments were remarkably better than those under the control.Furthermore,the enhancement effect of compound fertilizer treatment was significantly higher than the rest.Therefore,the compound fertilizer treatment was recommended as a fertilization scheme for young tea plants.
