2、要:【目的】研究BGA土壤调理剂在不同土壤类型中对甘蔗苗期生长的影响,为BGA土壤调理剂在生产上的应用提供参考。【方法】以桂糖02—281和R0c22作为试验品种,采用室外桶栽试验,分别以壤土和粘土为栽培基质,设不同BGA施用量(0、2、4、6、8g瓜g土)处理及施用复合肥(1.2g/kg土)处理,测定不同处理对甘蔗苗期叶片叶绿素含量、株高和叶片营养元素含量。【结果】桶栽甘蔗施用BGA土壤调理剂,可促进甘蔗苗期的生长,提高叶片叶绿素含量,增加植株高度,明显提高甘蔗叶片中N、K含量。在同类型土壤条件下不同甘蔗品种
3、间的效应一致,而对于同一甘蔗品种下粘土施用效果比壤土显著,其中6、8班g土施用量的促进效果较显著。【结论】BGA土壤调理剂对桶栽甘蔗苗期生长具有促进作用。关键词:土壤调理剂;BGA;甘蔗;苗期;生长效应中图分类号:S156.2文献标志码:A文章编号:2095—1191(2013)03一0442一05InnuenceofapplyingBGAconditionerongrowthofsugarcaneseedlingLIANGQiang,XIANWu,GUIYi—yun,LEIJing—chao,FANGFeng
