| 摘 要： | 为提高柚木轻基质容器苗质量,在椰糠中添加基肥作为育苗基质,研究缓释肥和有机肥对苗木生长的影响。结果表明,添加缓释肥和有机肥能显著提高苗木生长量、生物量和保存率;施用单一肥料时,缓释肥最佳施用量为2.0和4.0 kg/m^3,有机肥最佳施用量为2.0 kg/m^3;缓释肥和有机肥同时施用效果比单一施用更好,但增效不显著;从苗木养分库的构建考虑,柚木轻基质容器育苗的最佳配方为椰糠+3.0 kg/m^3缓释肥+3.0 kg/m^3有机肥。

| Abstract: | In order to improve quality of Tectona grandis seedlings in light substract containers, effects of slow-release fertilizer and organic fertilizer combining with coconut residum on growth of T. grandis seedlings were studied. Results showed that using slow-release fertilizer and organic fertilizer could remarkably increase growth, biomass and preserving rate of seedlings. When applying single fertilizers, the optimal dosages of slow-release fertilizer and organic fertilizer were 2.0, 4.0 kg/m^3 and 2.0 kg/m^3, respectively. Slow-release fertilizer and organic fertilizer worked better together than alone,but the effect was not remarkable. Considering construction of nutrient reserves, the best formula was coconut residum + 3.0 kg/m^3 slow-release fertilizer + 3.0 kg/m^3 organic fertilizer. |
