In order to determine the optimal moulding process parameters of biomass seedling pots prepared from fermented cow dung mixed with corn stover, pressure, baking time, and temperature were taken as influencing factors, expansion rate, durability wet swelling rate (48 h), resistance damage evaluation indexes, Box–Behnken design response surface method was used analyze significance interactions among different factors in optimize process. The experiment conducted Biomass Laboratory Heilongjiang Bayi Agricultural University. interaction between results showed that optimum conditions obtained using following: a pressure 520.393 kN, 202.870 °C, time 8.573 min. model validated by testing value 10.522% for expansion, 99.598% 11.145% 4503.545 N damage. experimental verification deviation actual under this condition predicted is less than 5%, indicating reproduces well meets requirements. Based on determined experiment, total porosity, EC, pH be 67.32%, 1.63 mS/cm, 6.7, respectively, which met
