龙脑型阴香造林密度与施肥试验研究

开展龙脑型阴香 (Cinnamomum burmannii chvar. Borneol) 造林初植密度和施肥试验，3 a 生试 验林分析结果表明，不同密度和不同施肥处理对龙脑型阴香的生长（树高、地径和冠幅）有着显著的影 响，而且在主效因子（密度）、副效因子（施肥）以及两者的交互作用上均达到极显著差异（P<0.01）， 说明采用不同密度以及不同的施肥处理可调节林分生长，选择合适的处理组合可提高林分生长量。初步 结论认为营建龙脑型阴香原料林其初植密度以株行距 1.5 m×2.0 m 为宜，即 3 330 株 /hm2 且以复合肥 (N:P:K=15:15:15) 作基肥和追肥（即试验的 D2F1 组合），可在幼林期间可以获得较高的生长量。

Study on Planting Density and Fertilization Experiment of Cinnamomum burmannii chvar. Borneol

The preliminary planting density and fertilization experiments of Cinnamomum burmannii chvar. Borneol afforestation were carried out in 2016. The results of 3-year-old experimental forest analysis showed that different density and fertilization treatments had significant effects on the growth of C. burmannii chvar. Borneol (including tree height, ground diameter and crown width), and the main factors (density), side-effects (fertilization) and their interaction were significantly different (P < 0.01), that indicating adopted different densities and fertilization treatments can regulate the growth of C. burmannii chvar. Borneol stand, and the appropriate combination of treatments can improve the growth of stand. The preliminary conclusion is that the initial planting density is 3 330 plants/hm2 (plant space of 1.5 m ×2.0 m ) and compound fertilizer (N:P:K=15:15:15) is used as fertilizer ( D2F1 combination of this experiment), higher growth can be obtained during the young forest period.
