生物炭类型对植烟土壤碳库及烤后烟叶质量的影响
Effects of biochar types on carbon pool in tobacco-planting soil and quality of flue-cured tobacco leaves
摘要
Abstract
[Objectives]This paper aimed to study effect of biochar types on carbon pool in tobacco-planting soil and on flue-cured tobacco leaves quality. [Methods]We carried out the field experiment in 2013 at Hanzhong of Shanxi. The variety tested was Yunyan97. The experiment had four treatments, T1(conventional fertilizer), T2(T1+ peanut-shell-biochar 600 kg/hm2), T3(T1+rice-husk-biochar 600 kg/hm2), T4(T1+wheat-straw-biochar 600 kg/hm2). [Results](1) Adding biochar leads to increased organic carbon mineralization rate, dissolved organic carbon content, easy oxidation active organic carbon content, soil total carbon content and soil carbon management index, and also leads to decrease of microbial biomass-carbon content. (2) Adding biochar can reduce total sugar, reducing sugar, K/Cl, and sugar to nicotine ratio of cured-leaves, but increase Nic content, and RS/TS. (3) Adding peanut-shell-biochar can increase easy oxidation active organic carbon and improve soil carbon management index. Adding peanut-shell-biochar can also increase K+ content. (4) Adding wheat-straw-biochar can significantly increase soil total carbon content and Nic content of cured-leaves, exerting negative effect on quality of cured-leaves. [Conclusions] Adding biochar can activate soil carbon library, but different material source of biochar had different effects on tobacco leaf quality.关键词
