### 2.3.2. Experimental Conditions

From 31 July 2022 to 2 August 2022, the peanut digger-inverter experiment was conducted in Baishi Village, Tangjiang Town, Nankang District, and Ganzhou City, Jiangxi Province. In the peanut production experimental base of the Ganzhou Academy of Agricultural Sciences, Jiangxi Province, the experiment of the peanut digger-inverter was carried out. The experimental land size reached 0.5 ha, the terrain was flat, the soil was sticky, and the peanut variety was "Osmanthus 73". This kind of peanut is an upright type. The planting mode was single ridge and double row, and the ridge spacing was 90 cm. During the experiment, the peanut was fully mature, and the average plant height was 54 cm, which met the basic requirements for peanut harvest.
