| 摘 要： | 通过室内模拟试验和容器育苗试验，研究了控释肥的释氮特性及对火炬松苗木生长的效应。结果表明，与等养分量的普通肥相比，控释肥可以减少氮的挥发和淋洗损失，明显促进苗木生长，火炬松生物量成倍增加。控释肥的释氮速率与苗木需肥规律基本同步。

| Abstract: | Laboratory experiment and pot experiment were conducted to study the characteristics of nitrogen release of controlled release fertilizer and its effects on growth of Pinus teada seedling. The results showed that applying controlled release fertilizer could reduce the nitrogen losses (both NH 3 volatilization and NO 3 -1 leaching ) of fertilizer ,and enhance the growth of Pinus teada seedling significantly as compared with common compound fertilizer under equal amount of nutrient. The nitrogen releasing rate of controlled release fertilizer corresponded with the regularity of nitrogen demand during Pinus teada seedling growth. |
