Effects of Different Fertilization Measures on Maize Yield and Economic Benefits in Hexi Areas
探究不同施肥措施对河西地区玉米产量和经济效益的影响,为实施化肥减施、生物有机肥替代化肥以及提高玉米产量提供理论依据.采用随机区组排列设计,共设4个施肥处理:不施肥对照、常规施肥、基质+常规施肥减量15%、生物有机肥+常规施肥减量15%,以玉米品种中农29号为指示作物,研究不同施肥措施对玉米生育期、农艺性状、产量性状、产量及经济效益的影响.结果表明,生物有机肥600 kg/hm2+常规施肥减量15%处理的玉米增产效果最显著,与不施肥对照相比,株高、叶龄、茎粗分别增加了26.96%、22.73%、24.57%,穗行数、行粒数、穗粒数、百粒重分别增加16.67%、26.67%、28.57%、30.94%;产量达13195.48 kg/hm2,较对照不施肥处理增产73.28%;产值为23 751.86元/hm2,供试肥料的产投比为5.97,增收增产效果显著.因此,施用生物有机肥600 kg/hm2+常规施肥减量15%(磷酸二铵510.00 kg/hm2、尿素233.75 kg/hm2、硫酸钾233.75 kg/hm2)对玉米的生物学性状具有一定的改善作用,增产增收效果显著,同时可减少化肥的使用量,建议在河西地区主要玉米种植区大面积推广应用.
To explore the effects of different fertilization measures on the yield and economic benefits of maize in the Hexi region,and to provide theoretical basis for reducing chemical fertilizer application,substituting chemical fertilizer with bio-organic fertilizer and increasing corn yield,a randomized block design was adopted in this study with 4 fertilization treatments set as no fertilization(the control),conventional fertilization,substrate+15%reduction of conventional fertilization,and bio-organic fertilizer+15%reduction of conventional fertilization.Maize variety Zhongnong 29 was used as the indicator crop to study the effects of different fertilization measures on the growth period,agronomic traits,yield traits,yield and economic benefits of maize.Results showed that the treatment of 600 kg/ha bio-organic fertilizer+15%reduction of conventional fertilization had the most significant effect on increasing corn yield.Compared with the no-fertilization control,the plant height,leaf age and stem diameter increased by 26.96%,22.73%and 24.57%,respectively,the number of rows per ear,grains per row,grains per ear and 100-grain weight increased by 16.67%,26.67%,28.57%and 30.94%,respectively,and the yield reached 13 195.48 kg/ha,with an increase of 73.28%over the control.The output value was 23 756.81 Yuan/ha,and the output-input ratio of the tested fertilizers was 5.97,with significant effects on increasing income and yield.Therefore,the application of 600 kg/ha bio-organic fertilizer+15%reduction of conventional fertilization(510.00 kg/ha diammohillm phosphate,233.75 kg/ha urea,and 233.75 kg/potassium sulfate)has a certain improvement effect on the biological traits of corn,with significant effects on increasing yield and income,and can also reduce the use of chemical fertilizers.It is recommended to be widely promoted and applied in the main corn planting areas of the Hexi region.
