【摘要】 为探明有机无机肥料配施对玉米产量和品质影响，以玉米品种合联1589为材料，设置CK（有机肥22.5 kg/50 m~2）、Y1（有机肥22.5 kg/50 m~2+过磷酸钙2.25 kg/50 m~2+氯化钾0.95 kg/50 m~2）、Y2（有机肥22.5 kg/50 m~2+尿素0.67 kg/50 m~2+氯化钾0.95 kg/50 m~2）、Y3（有机肥22.5 kg/50 m~2+尿素0.67 kg/50 m~2+过磷酸钙2.25 kg/50 m~2）、Y4（有机肥22.5 kg/50 m~2+尿素0.67 kg/50 m~2+过磷酸钙2.25 kg/50 m~2+氯化钾0.95 kg/50 m~2）5个处理，测定各处理产量及产量构成，籽粒全氮、全磷、全钾、可溶性蛋白和可溶性糖含量。结果表明，Y4处理的玉米穗粗8.87 cm、穗长19.33 cm、百粒重38.47 g、小区产量41.03 kg，较CK分别增长15.6%、20.0%、14.9%、70.0%;Y4处理的玉米籽粒全氮含量为2.47%，全磷含量为0.57%，粗蛋白含量为12.39%，均较CK明显提升；Y2～Y4处理间可溶性糖含量差异不明显。合理的有机无机肥料配施能为玉米生长发育提供养分，本文为玉米生产实践中科学施肥提供参考。更多还原

【Abstract】 To investigate the effects of combined application of organic and inorganic fertilizers on maize yield and quality, maize variety Helian 1589 was used as the material, and 5 treatments were set up: CK(organic fertilizer 22.5 kg/50 m~2), Y1(organic fertilizer 22.5 kg/50 m~2+superphosphate 2.25 kg/50 m~2+potassium chloride 0.95 kg/50 m~2), Y2(organic fertilizer 22.5 kg/50 m~2+urea 0.67 kg/50 m~2+potassium chloride 0.95 kg/50 m~2), Y3(organic fertilizer 22.5 kg/50 m~2+urea 0.67 kg/50 m~2+superphosphate 2.25 kg/50 m~2), and Y4(organic fertilizer 22.5 kg/50 m~2+urea 0.67 kg/50 m~2+superphosphate 2.25 kg/50 m~2+potassium chloride 0.95 kg/50 m~2), the yield and yield composition of each treatment, as well as the content of total nitrogen, total phosphorus, total potassium, soluble protein, and soluble sugar in grains were determined. The results showed that Y4 had a spike thickness of 8.87 cm, a spike length of 19.33 cm, a 100 grain weight of 38.47 g, and a plot yield of 41.03 kg, which increased by 15.6%, 20.0%, 14.9%, and 70.0% respectively compared to CK. The total nitrogen content, total phosphorus content, and crude protein content of Y4 grains were 2.47%, 0.57%, and 12.39% respectively, which were significantly higher than those of CK; the difference in soluble sugar content between Y2 and Y4 was not significant. Reasonable application of organic and inorganic fertilizers can provide nutrients for the growth and development of maize. This article provides a reference for scientific fertilization in maize production practice.更多还原
