Reviewer 2 Report
Congratulations ! A first-class paper. At last we have data supporting the need for better airflow control with airblast/orchard spraying. Your literature review is appropriate, and is international - so many reviews I have read this year are very parochial. You have encompassed a good amount of relevant literature.
Your research layout is good, it may have been improved slightly by having many interconnected annemometers but at a huge expense. It is refreshing to see deposition data alongside airflow data.
The paper is extremely well written yet I see no acknowledgements to any editorial support so I must congratulate the authors on their high standard of written English.

Reviewer 3 Report
This manuscript presents an interesting experiment to determine airflow velocity distribution under different conditions for air-assisted spraying applications.
In this way, I only suggest some minor revisions regarding Section 2.3:
In line 154 is mentioned, "... five sampling points were arranged as shown in Figure 8.".
However, Figure 8 doesn't seem related to this sampling point arrangement. Maybe a new Figure should be added where it is demonstrated that "Adjacent sampling points were 0.4 m apart horizontally and 0.4 m apart vertically".
In the same paragraph, these points are marked as "A1–A5, B1–B5, and C1–C5 (A, B, and C correspond to the outer, middle, and inner layers, 157 respectively)".
To make the article's content easier to follow, please consider changing the denominations A, B and C to O, M and I, as it refers to the Outer, Middle and Inner layers.
If the authors can clarify why two types of sprayers are used, it would also improve the quality of the manuscript.

Round 2
Reviewer 1 Report
Authors taken into account my comments and suggestions. However during revised of manuscript was made mistake. Numbers in main text are not compatible with numbers in references (e.g. in main text No. [27] "Operational quality of air-assisted orchard sprayers (NY/T992-2006)" airflow delivery standard, whereas this norm has in References list No. [26]).
