Against this backdrop, the experiment compared conventional planting with the adjusted dense planting. Under normal conditions, the individual tubers were indeed larger, but there was a significant difference in size, and the yield was mostly around 2 000 kilograms per mu. After changing to a reasonable planting density and synchronizing water and fertilizer management, the performance in the fields was noticeably different. The yield increased to around 2 600 kilograms per mu, an increase of nearly 30%. More intuitively, the size of the tubers was more concentrated. The rate of marketable tubers rose from about 85% to 92%, while small tubers and deformed tubers decreased significantly. From this, it is easy to see that dense planting not only brings about an increase in yield, but also improves the appearance (Li et al., 2019; Meng et al., 2025). 6.3 Summary of case experience and replicability evaluation Before discussing the promotion, it is necessary to re-examine the results in the specific conditions. The results in Dingxi did show significant changes. Intensive planting led to a nearly 30% increase in yield, but this was not simply achieved by simply increasing the density. One important prerequisite for such an effect in this area is that irrigation is in place and fertilization is also well done. On this basis, the rate of commercial potatoes increased simultaneously, and both yield and quality benefited. However, this situation is not suitable for all places. In contrast, in areas with better water and fertilizer conditions, there is still more room for improvement after intensive planting; while in regions with high humidity or heavy disease pressure, the density needs to be appropriately reduced and management needs to be strengthened. Overall, this case indicates that, under the premise of similar ecological conditions and complete supporting measures, reasonable intensive planting has the potential for promotion in similar areas in the northwest, but specific approaches still need to be determined based on local conditions (Li et al., 2020; Meng et al., 2025). 7 Application Prospects and Promotion Value of Rational Plant Spacing Technology 7.1 Adaptability of potato planting spacing patterns in different ecological zones When it comes to dense planting in production, it is difficult to find a set of standards that are applicable everywhere. In many cases, it still depends on how local conditions restrict things. For example, in areas like the northwest plateau with low precipitation, without stable irrigation, even if the density is increased, it is hard to achieve good results; conversely, in regions with abundant rainfall in the south, if the density is too high, diseases tend to concentrate more easily, and in such cases, it is necessary to reduce the planting quantity and improve ventilation conditions. In short-growing cool regions with short growing periods, it is common to appropriately densify to speed up the process; while in fields with long growing periods and good soil quality, it is even more necessary to prevent premature closure. Considering the differences in varieties, some plant types have a compact structure and are more tolerant of dense planting, while others with vigorous branches and leaves are not suitable for being crowded together. In general, the idea of dense planting is the same, but the methods must be adjusted flexibly according to local conditions and varieties (Li et al., 2020; Rens et al., 2021). 7.2 The significance of reasonable plant spacing for large-scale and mechanized production During the process of promoting large-scale planting, dense planting is often regarded as a "cost issue" at first, as the amount of seeds used and the investment will increase. However, when viewed from the perspective of mechanization, this concern may change. When planting over a large area in contiguous rows, reasonable increase in density can fully utilize the land potential, resulting in higher output per unit area, and the total cost can be more easily spread out. At the same time, mechanical operations have clear requirements for row spacing and plant spacing, and the dense planting plan precisely provides a unified standard.
