However, it is also necessary to consider moisture conservation measures during droughts to avoid the situation where "the ridge is raised but the yield is reduced due to water loss". Overall, the ridge height is more like an interface connecting environmental control and mechanical operations. Instead of providing a single value, it is better to manage it flexibly using an interval-based approach. Looking back, there are still several directions for further exploration in related research. First, truly place the rate of marketable potatoes at the core position, uniformly set the grading standards, incorporate weight, appearance defects and mechanical damage into the evaluation, and conduct multi-year and multi-gradient ridge height experiments in different regions to fill the gap of "the insufficient quantification of the relationship between ridge height and marketability rate". Second, introduce root zone gas and water monitoring, not just focusing on the results, but monitoring the process as well, such as the peak CO₂ level after rain, the speed of re-oxygenation of the ridge body, and then analyze these indicators in combination with the occurrence of abnormal and cracked potatoes. The existing forced aeration studies have actually provided a set of reference measurement and interpretation ideas. Third, ridge height should not be studied alone, but should be optimized together with factors such as mulching, drip irrigation, water and fertilizer integration, and planting density. Multiple studies have shown that raised beds with mulching can increase temperature and yield, and drip irrigation can also improve the marketability rate and income. Single-factor experiments without integrated management often cannot be directly applied to production. For the production end, a more feasible approach is to verify different ridge heights through small plots, then use the marketability rate and net income as the basis for decision-making, and finally form a standard ridge type that can be promoted.
