不同耕作模式和生物炭添加对黑土区土壤氮磷转化及玉米生长的调控
Shuitu Baochi Xuebao[目的] 为探究不同耕作模式和生物炭施加量对黑土区农田土壤氮磷转化和玉米生长发育的影响。[方法] 通过野外大田试验,设置2种耕作(深耕和浅耕)和5个生物炭添加处理(0,3,6,9,12 t/hm2),探究不同耕作模式和生物炭施加量对土壤氮磷组分、酶活性及玉米生理特性的综合影响。[结果] (1)深耕和浅耕配合施加生物炭可有效改善土壤结构,提高团聚体几何平均直径,降低破坏百分比,且深耕处理效果优于浅耕处理;(2)施加生物炭提高土壤氮磷组分、脲酶活性和碱性磷酸酶活性,施加9 t/hm2生物炭效果最好 ...
