摘　　要：通过叶面喷洒,探讨生物有机肥龙峰1号、龙峰2号和SOD液肥对玉米的增产效果与机理.结果表明：不同品种玉米于小喇叭口期叶面喷施生物有机肥后能有效促进玉米植株的生长速度,喷施后2周,处理比CK株高增加2.51~11.52 cm,单株叶片数增加0.11~0.91片,差异性达到极显著水平（P〈0.01）;喷施后抽雄期,处理比CK株高增加3.03~15.51 cm,单株叶片数增加0.24~2.08片,差异性达到极显著水平（P〈0.01）;喷施后灌浆期,处理比CK株高增加1.94~17.92 cm,单株叶片数最高增加0.33片,差异性达到极显著水平（P〈0.01）.综合分析叶面喷施生物有机肥的增产作用可知,叶面喷施SOD液肥增产效果最好,比CK增产60.71 kg/667m2,增产率达到9.46%;叶面喷施龙峰1号比CK增产34.96 kg/667m2,增产率达到5.45%;叶面喷施龙峰2号比CK增产34.90 kg/667m2,增产率为5.44%,差异性均达到极显著水平（P〈0.01）.表明玉米叶面喷施生物有机肥是一项简单易行的增产措施,在大面积生产中应大力提倡和推广应用.The yield-increasing effect and mechanism of three bio-organic fertilizers on maize by foliage spray were discussed in this paper.The results showed that bio-organic fertilizer could promote the growth speed of different maize varieties effectively.The investigation results after two weeks spraying displayed that the spraying processing more than the CK height 2.51 ~11.52 cm,number of leaf per plant increased from 0.11 to 0.91,the differences were significant（P〈0.01）;on the tasseling stage,the spraying processing more than the CK height 3.03 ~ 15.51 cm,number of leaf per plant increased from 0.24 to 2.08（P〈0.01）;on the filling stage,the spraying processing more than the CK height 1.94 ~ 17.92 cm,the highest number of leaf per plant increased 0.33（P〈0.01）.SOD liquid fertilizer had the best yield-increasing effect,increasing yield 60.71 kg per 667 m2 compared with CK,the increasing rate was 9.46%;spraying Longfeng No. 1 increased yield 34.96 kg per 667 m2 compared with CK,the increasing rate was 5.45%;spraying Longfeng No. 2 increased yield 34.90 kg per 667 m2 compared with CK,the increasing rate was 5.44%（P〈0.01）.Foliage spray with bio-organic fertilizers on maize is a simple stimulation on increasing yield,it should be advocated for application and extension.
