Abstract

In order to explore the best ratio of chemical fertilizer and biogas slurry in the process of biogas slurry returning to the field, experiments were carried out with different fertilization methods such as different proportion of biogas slurry replacing chemical fertilizer and whether topdressing or not. When the proportion of biogas slurry instead of chemical fertilizer was 60% to 70%, the weight of per plant and leaf of maize reached the maximum value, which were 1064.37g and 959.13g, respectively. When the proportion of biogas slurry replacing chemical fertilizer were 60% to 70%, the content of available phosphorus was the highest. The content of soil total nitrogen, ammonium nitrogen and nitrate nitrogen was the highest when the proportion of biogas slurry replacing chemical fertilizer was 80%, and the content of soil alkali hydrolyzable nitrogen was the highest when the proportion of biogas slurry replacing chemical fertilizer was 70%. In terms of the yield of silage corn and the content of soil nutrients, and the effect is the best when the proportion of biogas slurry instead of chemical fertilizer was between 60% and 80%.
