稀土和氮磷钾配合施用对油茶幼林生长发育质量的影响

Effect of Rare Earth and Nitrogen Phosphorus and Potassium Combined Fertilization on the Growth and Development Quality of Young Camellia Plantation

采用稀土和氮磷钾肥等不同的施肥方式对油茶幼林进行培育,将9种施肥方式与2组对照组进行对比,对比不同施肥方式之下油茶幼林冠幅、株高生长情况,结果显示,处理3与处理7施肥方式中采用相等钾肥浓度,油茶的长势以及产量差异较大,说明油茶幼林生长中K肥起着一定作用,非主要因素。单独施用稀土微肥效果有限,应与磷肥、氮肥、钾肥联合运用,注意施用量与施工时间间隔,将其控制在最佳限度内。同时,稀土施肥过程中,应当结合植物类型及其生长阶段采用适宜施肥量。

In this paper,different fertilization methods such as rare earth,nitrogen,phosphorus and potassium fertilizer were used to cultivate young camellia oleifera forest.Nine fertilization methods were compared with two groups of control group,and the growth of crown width and plant height of young camellia oleifera forest under different fertilization methods were compared.The results showed that the growth and yield of camellia oleifera were greatly different when the same potassium fertilizer concentration was used in treatment 3 and treatment 7,The results show that K fertilizer plays a certain role in the growth of camellia oleifera young forest,which is not the main factor.The effect of applying rare earth micro fertilizer alone is limited,so it should be combined with phosphorus fertilizer,nitrogen fertilizer and potassium fertilizer,pay attention to the application amount and construction time interval,and control it within the best limit.At the same time,in the process of rare earth fertilization,appropriate fertilization amount should be adopted in combination with plant types and their growth stages.
