摘要:
通过大田试验研究炭基土壤改良剂的不同施入量(0、10、20、30 t/hm2)对旱作农田土壤碳、氮含量的影响。结果表明,炭基土壤改良剂可有效提高土壤有机质、全氮、微生物生物量碳、微生物生物量氮的含量,且随着施入量的增加而提高。与CK相比,处理组土壤有机质含量提高3.19%~25.93%,土壤全氮含量提高2.20%~16.18%,土壤微生物生物量碳含量提高19.23%~73.93%,微生物生物量氮含量提高24.94%~89.51%,且均在施入30 t/hm2炭基土壤改良剂时达到最大值。因此,添加炭基土壤改良剂具有提高土壤有机质及碳、氮的含量、提升土壤养分持续供给的效用。炭基土壤改良剂的推荐用量为20 t/hm2
