Effects of Different Irrigation and Drainage Modes on Lodging Resistance of Super Rice Japonica 9108

Round 1

Reviewer 1 Report

       The authors describe the effects of three irrigation and drainage modes on rice lodging and yield. The differences between the FSI, RC-CI and DPS treatments were analysed in detail by Growth indexes, Stem morphological indexes, Material production indexes and Stem mechanical indexes. Ultimately, considering the yield and lodging resistance of the super rice "Japonica 9108", RC-CI are the best irrigation and drainage mode, followed by DPS. However, I have some reservations regarding the methods used and the data recorded thereafter:

a) Make a table in a standard way (three-line table, line thickness, length, etc.);

b) Use the number of decimal places correctly, for some data, one or two decimal places are sufficient;

c) Detailed description of each treatment, how to irrigate, how to control precipitation in Materials and methods;

d) Description of biological replicates;

e) figure or table captains require detailed descriptions.

f) Following a thorough review that deals with all issues raised, the English should be revised by qualified person

Specific suggestions are as follows:

L16, L20: one decimal place

L21: Severe drought stress is unknown because without soil moisture data you can only say osmotic stress;

L92: Refer to another article and change the sub-title;

L95: reserved to integers, with spaces between numbers and units;

L100: What is the P index, please explain;

L106: exchangeable K, Number to one decimal place;

L109: Is the barrel square?

L119: The compounds P2O5, K2O etc. do not exist in soils or in fertilisers. This an outdated convention that has no scientific basis. Please see https://doi.org/10.1007/s11104-020-04593-2

L125: Define FSI, RC-CI and DPS;

L131: What is Lower limit of irrigation, Upper limit of irrigation and Upper limit of rain storage? Is it under the shelter and how is the precipitation controlled?

L136: Are the two holes in the same bucket?

L149: How many buckets are these 5 holes in?

L162: How many biological replicates?

L177: Instrument information, company, city...

L182: What are the references for items 2, 3, and 4?

L189: Data analysis needs a more detailed description

L193: Should this section go into the Materials and methods section. In addition, please provide a date table for each reproductive period in the Materials Methods or Supplementary Tables;

L201: Data is retained to integers;

L230: Adjust the number of decimal places, except for M1, keep one decimal. How did you measure plant height to 3 decimal places?

L250: Pay attention to decimal places;

L271: For Fig. 2a, there is no statistical analysis, how many replicates? Trends in fresh and dry weight not consistent? For Fig. 2b, I can quickly see the difference in stem and ear between treatments, but the difference in leaves cannot be compared.

L323: Modify according to the three-line table standard. The lines look a little messy;

L422-423: But there is no data for these indicators, such as thousand-grain weight, seed setting rate and so on.

L421-433: The authors claim that RC-CI significantly increases yield, but there is no evidence for any yield increase, such as photosynthesis, grain traits;

L434: The calculation process for the ENTROPY TOPSIS method should be transferred to the Materials and Methods section;

L454: Is the table below Table 6 without a heading Table 7?

Reviewer 2 Report

The paper is well written and adequately describes the research. Some technical editing related to the English composition will help the reader better understand the paper.

I am concerned that some of your conclusions may not be supported by the data and its analysis. You may want to especially look at your analysis of the relationship between the methods of irrigation and plant yield. 

Here are some minor concerns and questions for clarity: 

Irrigation practices for Rice

Line 28: some editing is required for better English composition, e.g. “….making the rice yields to reduce” could be: ,resulting in reduce rice yields.

Line 37: What is International Rice? International Rice Research Institute?

References: I think the standard procedure is to have the author first followed by the year of publication, the paper title, and then the journal in which the paper is published. The reference number (2) is not in standard format.

Line 39: high rice yield? Do you mean to say high yielding rice varieties? that are prone to lodging.

Line 205: Not sure what do you mean by “… the two-year trial data showed similar laws.”

Lines 225-229: To analyze the relationship between irrigation methods and plant yield, we need to know the amount of irrigation water applied for each of the three treatments. That, combined with the amount of rainfall, will tell us the total amount of water available to the plants in each of the three water treatments. In the absence of this information, I am not sure whether you can arrive at such conclusion.
