3.1. Single-Factor Simulation Test 3.1.1. Influence of Soil Moisture Content on the Number of Broken Bonds in StrawThe results of the single-factor simulation test are shown in Table 2. The largest number of bonds broken was 574 when the soil moisture content was 12 ± 1%, but the average time for a straw to be entirely cut was the shortest, 0.067 s. This shows that the soil was hard and conducive for cutting straw when the soil moisture content was low.
