不同施肥措施对河西地区玉米产量及经济效益的影响
Effects of Different Fertilization Measures on Maize Yield and Economic Benefits in Hexi Areas
摘要
Abstract
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.关键词
