保水剂不同用量对土壤理化性状和木薯产量的影响

Effects of different dosages of water-retaining agent on physical and Chemical properties of Soil and yield of cassava

  • 摘要: 以木薯品种新选048为试材,进行保水剂不同用量对土壤理化性状及木薯产量的影响试验,探讨木薯施用保水剂的最佳用量及经济效益.结果表明:随着保水剂施用量的增加,土壤含水量增加,土壤毛管孔隙度、总孔隙度增大,土壤有机质、碱解氮、速效磷、速效钾含量增加.木薯施用保水剂后可达到增产、增收的效果,其最佳施用量为30kg/ha.
