Abstract:

To investigate the partial substitution of earthworm manure for reduced fertilizer application in soybean cultivation,and to investigate the effects of different combinations of earthworm manure and fertilizer on soybean yield and quality,the suitable combination ratio of earthworm manure and fertilizer for soybean cultivation was selected through statistical analysis of soybean agronomic traits,yield traits,quality traits,and soil indicators.The results showed that compared with no fertilizer application,single application of earthworm manure,single application of chemical fertilizer,and different ratios of earthworm manure and chemical fertilizer can all promote the growth and nutrient absorption of soybeans.The promotional effect of T1 treatment was most significant.Compared with CK0(unfertilized),T1(80% fertilizer+25% earthworm manure)showed a significant increase in plant height,number of plant nodes,grain weight per plant,grain number per plant,hundred grains weight per plant,and pod number per plant.However,compared with CK1(100% fertilizer application),T1(80% fertilizer+25% earthworm manure)showed increases of 5.84%,3.23%,17.10%,13.48%,and 20.04% in plant height,number of plant nodes,grain weight per plant,ear number per plant,and pod number per plant,respectively.The yield of T1 and T4 treatments was significantly higher than that of CK0(unfertilized)treatment at the 0.01 and 0.05 levels.Compared with CK1(100% fertilizer),the yield increased by 9.89% and 22.67%,respectively.Compared with CK0(without fertilization),T1 and T4 treatments increased protein content by 2.59 and 3.31 percentage point,and total egg fat increased by 1.55 and 1.99 percentage point,respectively.Compared with CK1(100% fertilizer application),the protein content increased by 2.34,3.06 percentage point,and the total egg fat increased by 1.38,1.82 percentage point,respectively.The soil bulk density of T4(20% fertilizer+100% earthworm manure)was 0.90 g/cm3,which was the lowest value of the experimental treatment.The soil bulk density of T1 and T4 increased by 3.88% and 12.62% respectively compared to CK1(100% fertilizer).In summary,the combination of T1(80% fertilizer+25% earthworm manure)and T4(20% fertilizer+100% earthworm manure)has the most significant comprehensive improvement effect.Taking into account factors such as the cost of earthworm manure,it is recommended to choose a ratio of 180 kg/ha fertilizer(3∶1 for diammonium and urea)+5 625 kg/ha earthworm manure in soybean production.
