Shuitu Baochi Xuebao, 2018 为明确施用生物炭对砒砂岩与沙复配土壤水分保持及肥力提升的影响，采用盆栽试验，研究了不同生物炭施用量（0，10，20，30，50 g/kg（以风干土计））对砒砂岩与沙复配土壤理化性状及玉米生长的影响。结果表明：在种植玉米一季后，施用生物炭可显著降低复配土壤容重，尤其当生物炭施用量达到30 g/kg时，土壤容重可降低至1.37 g/cm3，但当生物炭施用量增加到50 g/kg时，土壤容重又出现增加的趋势；土壤田间持水量随生物炭施用量的增加呈显著增加趋势，但当施用量增加到50 g/kg时又会出现下降趋势 ...

生物质炭和果胶对再生水灌溉下玉米生长及养分、重金属迁移的影响
Shuitu Baochi Xuebao, 2017 利用根箱试验方法比较了生物质炭和果胶对再生水灌溉下土壤—植物系统养分和重金属迁移特征的影响及差异性。结果表明，再生水灌溉不利于植物的生长，果胶和生物质炭两个处理相比，虽然植株生长无显著差异，但果胶处理植株的生长状况优于生物质炭处理；再生水灌溉时，果胶处理地上部生物量比对照增加了59.32%。与蒸馏水灌溉相比，再生水灌溉增加了根际土壤pH；灌溉水源相同时，果胶处理根际土壤pH略低于生物质炭处理。生物质炭和果胶都增加了土壤养分的含量，果胶对土壤碱解氮、有效磷和有机质的增加效果优于生物质炭 ...
