配方施肥对油茶中幼林营养生长的影响

The Effect on Vegetative Growth of Young Oil Camellia oleifera with Different Formula Fertilization

在广西巴马县连续3 a研究不同配方施肥(处理A:N∶P_2O_5∶K_2O=16∶6∶8;处理B:N∶P_2O_5∶K_2O=12∶8∶10;处理C:N∶P_2O_5∶K_2O=10∶10∶10;CK:不施肥(对照))对油茶中幼林营养生长的影响。结果表明,配方施肥对油茶中幼林的营养生长有良好促进作用,其树高、地径、冠幅的肥效反应均表现为:处理A>处理B>处理C>CK,处理A施肥效果最佳,其各项生长指标增长量均明显高于其他处理,CK(不施肥)处理表现最差。

Study the effcets of different formula fertilization on the vegetative growth of yong oil Camellia oleifera for 3 consecutive years in Bama County of Guangxi Province. Four treatments were included in the experiment, they are A （N： P205：K2O = 16：6：8 ） ,B （ N： P2O5：K2O = 12：8： 10） ,C（ N： P2O5 ： K2O = 10： 10： 10） and CK （unfertilized）. The results showed that formula fertilizer could stimulated the vegetative growth of young oil Camellia oleifera,response of formula fertilizer on the height, diameter and crown were the treatment A 〉 treatment B 〉 treatment C 〉 treatment CK. So the fertilization of the treatment A had the best effect,The increment of treatment A growth performance was all significantly higher than other treatments,The treatment of CK （unfertilized） was the low- est. The above research results can provide the scientific base for fertilization in tea plantation.
