Reviewer 2 Report

Reviewer comment on Seeding performance caused by inclination angle in a centralized seed metering device for rapeseed

The paper is well written and is focused on Seeding performance caused by inclination angle in a centralized seed metering device for rapeseed.  The results contributed to improving knowledge of seed filling characteristics of the centralized seed-metering device at inclination condition and should help improve seeding performance by adjusting seed layer height and installing seed cleaning brush.  However here are my comments and suggestion that can help improve the quality of the manuscript:

1. I suggest that the image quality of the figures should be improved upon
2. Table 3 and 6 should be well positioned on top of the table on the new page where it appeared
3. Subsection 2.3.2 should start from a new page, same for subsection 2.4/2.4.1
4. Check the paragraph on line 167, very close to Table 2, same for line 172, close to equation 1
5. Labelling of Figure 9 should be well positioned.
6. Your manuscript has scanty cited references. I suggested you cite more references to support your discussions.
