Evaluation of the Synthetic Index of Bioorganic Fertilizers Prepared with Different Proportions of Mulberry Flavobacteria Residue
It is rich in carbohydrates,protein,organic matter,enzymes,and organic acid and is a high-quality raw material for the preparation of bioorganic fertilizer.To study the effects of different mulberry flavobacteria residue amounts on bioorganic fertilizer quality,five positive indices(organic matter,total nitrogen,P2O5,K2O,and humic acid)and four negative indices(total arsenic,total mercury,total lead,and total cadmium)were selected to evaluate the quality of bioorganic fertilizer pre-pared by different treatments.The results showed that all nine indices of the seven bioorganic fertilizer samples were in line with the standard requirements and could be used effectively;there were significant differences in the nutrient content of the bioorganic fertilizer prepared by the seven treatments.The nutrient index of the bioorganic fertilizer prepared with 95%mul-berry flavobacterial residue+5%rapeseed cake was the highest,and the overall quality was the best.There were significant differences in the heavy metal contents of the bioorganic fertilizers prepared by the seven treatments.The bioorganic fertilizer prepared from mulberry flavobacteria residue had significant advantages.It could be used as a bioorganic fertilizer substrate,and the effect was better when combined with a certain proportion of rapeseed cake.
