摘要:
为探讨不同类型生物炭对杉木人工林土壤氮素形态的影响,以福建省三明市莘口教学林场不同发育阶段杉木人工林为研究对象,选择2种不同类型生物炭(竹炭和木炭),研究其对杉木人工林土壤不同形态氮素的影响。结果表明:2种生物炭对土壤全氮含量影响较小且主要集中于表层,施炭处理1 a后,土壤水解氮含量均有显著提高,但从第2年开始水解氮含量逐渐下降,在第3年水解氮含量与对照无显著差异;2种生物炭对土壤无机态氮含量影响差异较小,竹炭处理的土壤无机氮含量有所增加,而木炭处理的则多为下降。施炭处理分别与发育阶段、土壤层次对土壤水解氮含量有明显的交互影响。生物炭对杉木不同发育阶段影响为:幼龄林 > 中龄林 > 老龄林。竹炭对土壤改良作用优于木炭。
Abstract:
Biochar, as a good sequestration agent, is also a new material for improving soil physical and chemical properties. Chinese fir plantation, at different developmental stage in Xinkou teaching state forest farm of Fujian Sanming, were studied to explore the effects of different types of biochar on soil nitrogen forms. Two different kinds of biochar (wood-biochar, bamboo-biochar)were choosed to find the influence of different type of biochar on soil fertility in the Chinese fir plantation. The results showed as follows:the biochar had little effect on soil total nitrogen on the surface in the 1st year. Biochar treatment had significantly increased soil hydrolysis nitrogen in the 1st year, then decreased in the 2nd year, and there was no significant difference compared to the control in the 3rd year. Two types of biochar had little influenced on inorganic nitrogen in the soil, bamboo-biochar treatment increased, but the woody-biochar treatment decreased mostly. There were significant interactive effects among biochar treatment, developmental stage and soil layer on the soil hydrolysis nitrogen. The influence of biochar on different developmental Chinese fir stages follow by:youth stand > middle stand > mature stand. Two types of biochar comparison showed that, bamboo-biochar is better than wood-biochar on soil improvement.
