Effect of moisture content, cutting speed, bevel angle and internode position on Cutting energy characteristics of Broomcorn stalk

The cutting of stalks is an important process in sorghum harvesting, forage harvesting, weeding, stalk shredding, andwn lamowing. Experiments were conducted to study the effect of moisture content, cutting speed, bevel angle and internode position on cutting energy of three genotypes of broomcorn stalk. The results showed that the amountof cutting energy was increased by increasing moisture content and bevel angle. The specific cutting energy obtained by dividing cutting energy into the cross-ectional of the stalk. The ANOVA results of specific cutting energy showed that all main effects were significant at 1% probability level.
