Abstract

Abstract:

In order to quantify the effect of biochar application on soil pH and provide theoretical basis for biochar application in soil improvement and fertility cultivation， based on the electronic databases CNKI， Wanfang and Web of Science， 413 biochar on soil pH case studies based on the keywords “Biochar”， “Biochar”， “soil pH” and “soil pH” were collected from 59 published literatures. Meta-analysis was implied to quantify the effect degree of soil conditions， biochar characteristics and biochar application amount on soil pH. The results showed that， compared with no biochar application， biochar application could significantly increase soil pH by 8.70%. In the strongly acidic soil （4.5<pH≤5.5） and extremely acidic soil （pH≤4.5）， the increase rate were the highest， which were 15.17% and 9.68%， respectively. Different biochar could significantly increase soil pH， and showed the trend as straw biochar （10.04%） > shell residue biochar （7.02%） > wood biochar （6.61%）. The biochar prepared at ≤400 ℃ had the best promotion effect of 15.26% under different pyrolysis temperatures， while， the increasing effect decreased with the increase of pyrolysis temperature， such as the pyrolysis temperature was between 400~700 ℃. The increasing effect was higher in 3 months， then the increase gradually slowed down.These results indicated that in strongly acidic soil （4.5<pH≤5.5）， straw pyrolysis biochar at low temperature （≤400 ℃） was preferred to be applied， which could better improve soil pH and provide scientific basis for the promotion and application of biochar in the future.

Key words: biochar, soil pH, Meta-analysis

摘要：

为量化生物炭施用对土壤pH的影响，为生物炭在改良土壤、培肥地力中提供理论依据，采用数据整合分析（Meta-analysis）的方法，基于中国知网、万方数据和Web of Science数据库，用关键词“生物炭”“Biochar”“土壤pH”和“土壤酸碱度”进行检索，收集到国内外关于生物炭对土壤酸碱度影响研究已公开发表的59篇文献中413组试验数据，分析土壤条件、生物炭特性、生物炭施用量等对土壤pH的定量影响。结果表明，与不施生物炭相比，生物炭施用能显著提高土壤pH，平均增幅为8.70%。其中，以强酸性（4.5<pH≤5.5）和极强酸性土壤（pH≤4.5）增幅最大，分别为15.17%和9.68%；不同原料生物炭对土壤pH的提升效果表现为秸秆类生物炭（10.04%）>壳渣类生物炭（7.02%）>木材类生物炭（6.61%）。不同热解温度下，以≤400 ℃制得的生物炭提升效果最佳，为15.26%；而在热解温度400~700 ℃时，随着热解温度升高，提升效果降低。施用生物炭3个月内土壤pH的增幅最大，之后增幅逐渐减缓。以上结果表明在强酸性（4.5<pH≤5.5）土壤中，优先选用秸秆低温（≤400 ℃）热解生物炭施用能更好地改善土壤pH，结果为生物炭的推广应用提供科学依据。
