闽西山区油茶幼林生物防火林带配方施肥研究初探

为研究施肥对原生土带防火路种植的油茶幼林的影响,运用正交试验设计对闽西山区幼龄油茶进行配方施肥试验。结果表明配方施肥对幼龄油茶生长有促进作用,生土带防火路种植油茶以N130P667K133微量15、N174P500K133微量10和N174P667K67微量53种配方施肥效果较好。肥料对幼龄油茶树高和幼林冠幅的影响效应依次为N>K>P>微量肥,N肥对油茶幼林的生长最为重要,在油茶生产中必须重视N肥的施用。试验表明,在原生土带防火路土壤养分条件较差的情况下,科学合理施肥有利于油茶的快速生长,促进林分迅速郁闭,更好地发挥其防火、生态和经济效益。

A Preliminary Study on Formula Fertilization for Ecological Firebreak Belt of Camellia oleifera Forest in Western of Fujian Province

In order to study the effects of fertilization on the raw-soil firebreak road, on young C. oleifera trees, The formula fertilization on young forest were studied by orthogonal which planted test design in mountainous areas of the western Fujian province. The results showed that formula fertilization could promote the growth of young forest of C. oleifera. There had good fertilization effects by formulas of N130P667K133 icronutrients15, N174P500K133 micronutrientslo and N174 P667 K67 micronutrients5. Effects of fertilizer on tree height and crown width of the young C. oleifera are N 〉 K 〉 P 〉 micronutrients. N fertilizer is the most important to the growth of the young C. oleifera, we should pay attention to N fertilizer in practice. The tests also showed that in the case of poor soil nutrient conditions of the raw-soil firebreak road, scientific and rational fertilization conducive to the rapid growth of C. oleifera, promote rapid stand canopy, and play its fire protection, ecological and economic benefits.
