摘要:
以生物炭、沙蒿粉和羊粪为试材，采用无植物盆栽模拟试验方法，研究有机物料在生物炭改沙中对沙土生物性质的影响，以探究有机物料在生物炭改沙中的增效作用。结果表明：不同有机物料均显著降低了沙土的真菌数量，但增加了微生物量C、N含量、细菌数量、放线菌数量，其增量表现为：生物炭+羊粪>生物炭+沙蒿粉>生物炭>羊粪>沙蒿粉。生物炭与羊粪或沙蒿粉混施分别较单施的累加效果平均高出2.8%和1.9%、10.4%和5.3%、5.7%和46.2%、21.5%和16.1%。脲酶活性混施较单施的累加效果分别高出4.88%~53.13%和8.33%~50.00%。相关性分析表明，pH与真菌数量呈显著负相关（r=-0.353*）；有效养分增量均与各生物指标均存在一定的正相关关系（r=0.188~0.889**）。总之，在生物性质方面，有机物料与生物炭具有协同增效作用，尤其表现在微生物量C、N含量、微生物数量和脲酶活性上。pH的提高显著降低了沙土的真菌数量；生物性质的改善为沙土有效养分的提高发挥了积极的作用。
Abstract:
Biochar,Artemisia powder and sheep dung were selected as experiment material,with plant-free outdoor training simulation experiment method,the effect of organic material on sandy soil biological properties and explore synergistic action of organic material in biochar improving sandy soil.The results showed that the number of fungi was reduced,but content of microbial biomass C,N,number of bacteria and actinomyces were all significantly increased by adding different organic materials.Incremental performance for,biochar+sheep manure>biochar+Artemisia powder>biochar>sheep manure>Artemisia powder.They were increased by 2.8% and 1.9%,10.4% and 5.3%,5.7% and 46.2%,21.5% and 16.1%,biochar mixed with sheep manure or Artemisia powder than separate application accumulation,respectively.Urease activity was improved by 4.88%-53.13% and 8.33%-50.00%,respectively.Correlation analysis showed that pH was negatively related to the fungi number significantly (r=0.353*);increment of effective nutrients with each biological indexes exist certain positive correlation (r=0.188-0.889**).In short,biochar had a synergistic effect with organic material in terms of biological nature,on microbial biomass C,N content and microorganism quantity and urease activity especially.The number of fungi was significantly reduced by increasing pH;the improved biological properties had played a positive role in increasing available nutrients of sandy soil.
