*4.1. Test Conditions*

Field tests on dandelion seed harvesting were conducted in a dandelion planting base at the Changyuan branch of the Henan Academy of Agricultural Sciences (Xinxiang City, Henan Province, China) [34]. The planting base was situated on a flat terrain, where dandelion plants grow well. The key parameters of dandelion plants and seeds were measured in the experimental field by measuring instruments. Dandelion plants have an average row spacing of 15 cm, an average height of 40 cm, and a seed moisture content of 9.82%. The growth cycle of dandelion was 3 months. A region some 30 m long and 10 m wide was selected from within the planting base as the harvesting test region. In addition, a harvester starting area and a parking area were also reserved on both sides of the test region (Figure 17).The photos of dandelion plants and dandelion seed crowns are shown in Figure 18.

The test instruments and devices include the self-propelled dandelion seed harvester, an anemograph, a tape, an electronic scale, a digital camera, and a rev-counter.
