Study on Application of Concentrated Biogas Slurry on Soybean
Concentrated biogas slurry can meet the basic standards of fertilizer use,and the nutrient elements are balanced and have quick effect.In the experiment,three key periods of flowering period,pod stage and grain stage of soybean growth were selected,sprayed 50％ biogas slurry fertilizer on the leaves,and analyzed the effect of biogas slurry spraying on the growth characteristics and yield of soybean.The experimental results showed that spraying biogas slurry could increase dry matter accumulation,plant height and root length,leaf SPAD value,pod number and 100 grain weight of soybean,and yield increased by 30.97％ compared with control,14.24％ compared with potassium dihydrogen phosphate,and the yield effect is obvious.
