摘要
为科学评价新型肥料对幼龄期马尾松人工林生长的影响,本研究以广西国有派阳山林场鸿鸪分场造林点的幼龄期马尾松人工林为研究对象,采用随机区组试验设计,设置袋控缓释肥、生物质炭基肥、非袋控肥和不施肥4种处理方式,跟踪测定林木生长状况。结果表明:对于广西国有派阳山林场鸿鸪分场的幼龄期马尾松人工林而言,施用新型肥料的效果均优于非袋控肥。与非袋控肥相比,施肥19个月后,施用0.5 kg袋控缓释肥和0.5 kg生物质炭基肥处理平均立木蓄积增长率分别提高了2.67%和16.36%。因此,施用新型肥料对幼龄期马尾松人工林的生长有明显促进作用。
To scientifically evaluate the effect of bag-controlled release fertilizer on the growth of young Pinus massoniana,taking the young Pinus massoniana plantation forest in Guangxi Paiyangshan Forest Farm as research object,randomized block experiment was designed with four fertilization treatments:bag-controlled release fertilizer application,biochar-based fertilizer application,non bag-controlled fertilization and no fertilization,and the forest growth was investigated continuously.Results showed that the effect of bag-controlled release fertilizer was better than that of non bag-controlled fertilizer for the growth of young Pinus massoniana plantation forest.After 19 months of fertilization,the average tree accumulation growth rates of the treatment with 0.5 kg bag-controlled release fertilizer and the treatment with 0.5 kg biochar-based fertilizer increased by 2.67%and 16.36%respectively than that of the treatment with non bag-controlled fertilizer.Therefore,application of bag-controlled release fertilizer can obviously promote the growth of young Pinus massoniana plantation forest.
