The timing of rice harvest often goes unnoticed in terms of its impact on quality, yet it is crucial in actual production. This study starts from this issue, observing the differences in rice quality at various time points as the harvest period changes. Three scenarios were set up in the experiment: early harvest, timely harvest, and late harvest. The moisture content of grains, the rate of whole and well-polished rice, and the eating quality of rice were measured and compared. The results show that the harvest time directly affects quality. Early harvest leads to high moisture content in grains, insufficient maturity, significantly lower rates of whole and well-polished rice, and poor eating quality of rice. At the appropriate harvest stage, the moisture content of grains remains at about 20%–25%, the rate of whole and well-polished rice is at a high level, and the eating quality is the best. If the harvest is too late, the moisture content of grains is too low, which can cause cracks, the rate of whole and well-polished rice decreases, and the eating quality also weakens. Considering all the performances, it can be seen that there is a relatively suitable harvest period range for the tested variety, during which both yield and processing quality and eating quality can be ensured. The relevant conclusions can provide a reference for the reasonable arrangement of harvest time in production and the improvement of the output level of high-quality rice.
