Abstract:

Improper application of soybean fertilizer can lead to late ripening,lodging,worsening of diseases and pests,and a decrease in fertilizer and yield benefits,to improve fertilizer efficiency and fully tap into the potential of soybean yield and quality,therefore,this article investigates the effects of seven fertilization modes F1(basic application of 3 000 kg/ha organic fertilizer+300 kg/ha chemical fertilizer),F2(basic application of 3 000 kg/ha organic fertilizer+150 kg/ha chemical fertilizer+topdressing 150 kg/ha chemical fertilizer),F3(basic application of 3 000 kg/ha organic fertilizer+225 kg/ha chemical fertilizer+topdressing 75 kg/ha chemical fertilizer),F4(basic application of 1 500 kg/ha organic fertilizer+75 kg/ha chemical fertilizer+topdressing 225 kg/ha chemical fertilizer),F5(basic application of 300 kg/ha chemical fertilizer),F6(basic application of 150 kg/ha chemical fertilizer+topdressing 150 kg/ha chemical fertilizer)and F7(basic application of 225 kg/ha chemical fertilizer+topdressing 75 kg/ha chemical fertilizer)on soybean growth,development,photosynthesis,yield,and quality through field experiments using a single factor experimental design.The results showed that increasing the application of organic fertilizer significantly enhanced the dry weight of soybean roots when compared to applying chemical fertilizer alone,applying chemical fertilizer alone with a base to top dressing ratio of 3∶1 was the most beneficial for increasing root dry weight.The combination of organic fertilizer and chemical fertilizer resulted in higher fresh leaf weight,dry leaf weight,fresh stem weight,dry stem weight per plant,as well as higher fresh weight and dry weight per plant when compared to single application of chemical fertilizer,and there were no significant differences in the above indicators among the treatments treated with single application of chemical fertilizer.The combination of organic fertilizer and chemical fertilizer increased the number of leaves per plant and leaf area index of soybean at pod bearing stage and filling stage,under the condition of no organic fertilizer application,the base to top dressing ratio of 3∶1 of chemical fertilizer was beneficial for improving the number of leaves and leaf area index of soybean.Compared to single application of chemical fertilizer,combined application of organic fertilizer and chemical fertilizer increased the photosynthetic rate at flowering and filling stages by 16.69%—21.66% and 14.99%—30.66%,respectively,unreasonable base to top dressing ratio of chemical fertilizer or reducing organic fertilizer dosage could affect the chlorophyll content and photosynthetic rate of soybean in the middle and later stages of growth and development.Increasing organic fertilizer application amount could increase soybean yield and protein content,while reduce fat content,applying chemical fertilizer alone with a base to top dressing ratio of 3∶1 was the most conducive to increasing yield.Therefore,it can be concluded that the combination of organic fertilizer and chemical fertilizer is significantly better than that of single application of chemical fertilizer in improving soybean growth and development,photosynthesis,yield,and quality,in addition,single application of chemical fertilizer performs better with a base to top dressing ratio of 3∶1.
