通过对比分析不同施肥处理对油茶不同品系产量的影响,研究了在不同平衡施肥处理下不同品系油茶的经济效益。结果表明:(1)N肥和P肥对增加油茶产量具有显著地影响,增施K肥对提高油茶产量和产投比有效果,但在幼林期增产效果不明显。(2)油茶各品系之间在相同施肥处理下产量增加具有显著差异。(3)在生产上,在经济条件不允许施肥的情况下垦复也是一种经营的好方法。
By comparing and analyzing the effects of different fertilization treatments on the yield of different varieties of Camellia oleifera, the economic benefits of different strains of Camellia oleifera under different balanced fertilization treatments were studied. The results showed that: (1) N fertilizers and P fertilizers had a significant effect on increasing the yield of Camellia oleifera. Increasing K fertilizers had the effect of increasing yield and yield of Camellia oleifera, but the effect was not obvious in the young stands. (2) There was a significant difference in yield between different lines of Camellia oleifera under the same fertilization treatment. (3) In production, reclamation is also a good way of doing business when economic conditions do not allow for fertilization.
