摘　　要：白浆土物理结构致密、养分含量及生物学活性低,是典型低产土壤。生物炭具备丰富养分数量,具备提高白浆土养分含量理论基础。试验采用盆栽方式,研究不同作物生物炭对白浆土养分含量及水稻产量影响。结果表明,生物炭增加白浆土各生育时期有机质、速效磷、全氮、全磷含量。在成熟期,BD、BY 有机质含量分别较BCK 增加0.52%、0.78%,BD、BY速效磷含量分别较BCK 增加10.06%、11.80%,BD、BY 全氮含量分别较BCK 增加2.57%、2.06%。在成熟期,BD、BY 净光合速率分别较BCK增加4.25%、0.33%。生物炭可增加水稻产量,水稻秸秆生物炭、玉米秸秆生物炭处理产量分别较对照增加7.00%、5.00%。Albic soil was a typical low-yielding soil with dense structure and low nutrient content. Biochar had abundant nutrients and theoretical basis for improving albic soil.The effects of albic soil nutrient and rice yield with different crop biochar were studied by pot experiment.The results showed that biochar increased the contents of organic matter,available phosphorus,total nitrogen and total phosphorus in all growth stages of rice. In the mature stage,the content of organic matter in BD and BY treatments increased by 0.52% and 0.78% than BCK,the content of available phosphorus in BD and BY treatments increased by 10.06% and 11.80% than BCK,and the content of total nitrogen in BD and BY treatments increased by 2.57% and 2.06% than BCK,respectively. In the mature stage,the rice net photosynthetic rates of BD and BY increased by 4.25% and 0.33% than BCK,respectively. The yield of rice straw biochar and corn straw biochar were increased by 7.00% and 5.00% than BCK,respectively.
