不同基质配比及复合肥处理对3年生楠木容器苗生长的影响

摘要

The study was based on analysis of the effect of substrate composition, type and application quantity of fertilizer on Phoebe chekiangensis, P.sheareri, P.bournei container seedling growth.The results showed that the growth of Phoebe chekiangensis performed the best under the condition of A3 ( peat︰garden soil︰perlite︰hull=2︰4︰2︰2) and B2 ( compound fertilizer 1; N︰P︰K=21︰6︰13; 750 g/m2 ); Different sub-strates had no significant difference on the growth of P.sheareri, and B4 ( compound fertilizer 2; N︰P︰K=21︰6︰13; 750 g/m2 ) was optimal treatment for the growth of P.sheareri; P.bournei in the condition of A1 ( peat︰garden soil ︰perlite =3 ︰4 ︰3 ) showed the growth advantage obviously, while different fertilizer treatments had no significant difference on the growth of P.bournei.%以基质配比、施肥种类和施肥量3种因素对3年生浙江楠、紫楠、闽楠容器大苗生长的影响进行研究。结果表明，浙江楠在基质A3（泥炭︰园土︰珍珠岩︰谷壳＝2︰4︰2︰2）与施肥B2（复合肥1的N︰P︰K为21︰6︰13；750 g／m2）条件下，生长表现最佳；不同基质对紫楠生长均无显著差异，且施肥B4（复合肥2的N︰P︰K为15︰15︰15；750 g／m2）对其生长最适；闽楠在基质A1（泥炭︰园土︰珍珠岩＝3︰4︰3）条件下表现出明显生长优势，不同施肥对其均无显著差异。
