摘    要:[目的]探究杉木人工幼林的施肥技术及其效益分析。[方法]在对7年生杉木人工幼林的施肥对比试验中,设3种施肥处理:钙镁磷肥500g/株、尿素250g/株和磷肥250g/株+尿素125g/株,不施肥为对照,采用挖环状沟施肥法,年底11月根据树高生长和胸径生长量调查,计算各试验区立木材积和蓄积量。[结果]施肥5年后杉木人工林的立木蓄积量,以施磷肥处理的效果最好,比对照区年均增加立木17.13m3/hm2,净产值增加33776元/hm2;磷肥+尿素混合施效果次之,比对照区年均增加立木9.04m3/hm2,净产值增加16284元/hm2;施尿素对林木作用不大,仅比对照区年均增加立木2.38m3/hm2。[结论]磷肥施用效果最佳,施入后杉木人工幼林的林木生长平稳.其效果随时间的推移越趋明显。

关 键 词:杉木  人工幼林  施肥技术

Abstract:[Objective] The study aimed to explore the fertilizer technology for young plantation of Chinese fir and its benefit analysis.[Method] In the contrast test on the fertilizer application for 7-year-old young plantation of Chinese fir,3 treatments of fertilizer application were set up as the calcium magnesium phosphate 500 g/plant,urea 250 g/plant and phosphate fertilizer 250 g/plant + urea 250 g/plant,with no fertilizer application as CK and they were applied to the young plantation through digging ring chan...
Keywords:Chinese fir  Artificial young plantation  Fertilization technology
