BGA土壤调理剂与氮磷钾肥配施对春玉米产量的影响

摘要

采用田间试验，研究BGA土壤调理剂与氮、磷、钾肥配施对玉米产量及其主要产量构成因素的影响。结果表明：BGA土壤调理剂与磷肥配施比CK（不施肥）增产54.9%，纯施BGA土壤调理剂比CK增产7.5%，而BGA土壤调理剂与氮肥、钾肥、氮磷钾复合肥配施分别比CK减产22.5%、9.4%、13.8%。因此，推荐在玉米生产上采用BGA土壤调理剂与磷肥配施，并建议加强BGA土壤调理剂与化肥配施对其他作物产量影响的研究。%Under the field experiment,the effects of applying BGA soil conditioner and nitrogen,phosphorus,potassium together on the yield of spring maize were studied. The results showed that comparing with the CK (no fertilizer),BGA soil conditioner and phosphorus fertilizer combined application increased the kernal yield by 54.9%,BGA soil conditioner single application increased the kernal yield by 7.5% ,while BGA soil conditioner and nitrogen fertilizer,potassium fertilizer,compound fertilizer combined application decreased the kernal yield by 22.5%,9.4%,13.8%, respectively.We suggested BGA soil conditioner and phosphorus fertilizer combined application on maize plantation,and the study of the yield of BGA soil conditioner combined application with fertilizer on other crops should be focused on.
