摘　　要：A machine with manual operation for mulch-laying machine with a punching arrangement was developed,and its performance was assessed at three different mulch paper thicknesses(15 m,20 m and 25 m),three different disc angles(35 degrees,40 degrees,and 45 degrees),three different punch spacings(250 mm,500 mm,and 1000 mm),and three different forward speeds(1.3 km/h,1.5 km/h,1.7 km/h)to investigate their effects on field capacity,effective field efficiency,and punching efficiency.Utilizing randomised block design and response surface methods,the experimental plan for optimization was created.All of the independent variables’combined effects on the dependent variables were found to be statistically significant.The influence of operating speed and mulch paper thickness was found to be the most significant on the dependent variable.The effective field capacity and field efficiency increased from 0.11 ha/h to 0.19 ha/h and 72.04 percent to 89.51 percent,respectively,by increasing mulch paper thickness from 15μm to 25μm and operating speed from 1.3 km/h to 1.7 km/h,whereas punching efficiency fell from 85.18 percent to 84.40 percent.Mulch paper of 15μm and a disc angle value of 40 degrees were optimised from the independent factors that were chosen for optimal soil covering over the laid plastic mulch sheet.Punching efficiency was maximised with performance optimised at 500 mm punch spacing.Additionally,the machine operated more efficiently at 1.5 km/h.
