Lycium barbarum, a plant belonging to the Solanaceae family, is widely used in China due to its abundant nutritional value. Although the current mechanized harvesting method of L. barbarum has effectively minimized production expenses, it continues to have the challenge of inconsistent quality of the produced L. barbarum. The objective of this paper is to evaluate the correlation of the separating force and hardness concerning the timing of harvesting, maturity, and variety. Thus, the optimal time for harvesting ripe L. barbarum can be determined to enhance the quality of selectively mechanized harvesting of this fruit. The experiment was conducted in a L. barbarum plantation located in Qinghai Province during the 2023 harvest period. Two occasions were studied focusing on the primary cultivars Ningqi No. 1 and Ningqi No. 7, examining the three ripening stages of L. barbarum harvested at various times throughout the day. The finding of this study showed that the separation force and hardness of L. barbarum fruits were influenced by the harvesting time, the fruit variety, and the level of maturity. The optimal timing for harvesting different types of L. barbarum varies. It was observed that Ningqi No.1 was best to be harvested in the late afternoon and evening (17:00-21:00), whereas Ningqi No.7 was most suitable to be harvested in the morning (7:00-9:00).
宁夏枸杞，茄科植物，由于其丰富的营养价值，在中国被广泛应用。虽然目前宁夏枸杞的机械化收获方法有效地降低了生产成本，但仍然存在所生产的宁夏枸杞质量不一致的问题。本文旨在评估分离力和硬度与收获时间、成熟度和品种的相关性。从而确定成熟宁夏枸杞的最佳收获时间，以提高这种果实选择性机械化收获的质量。该实验于 2023 年收获期在青海省的一处宁夏枸杞种植园中进行。研究了两个时期，重点关注主栽品种宁杞 1 号和宁杞 7 号，考察了全天不同时间收获的三个成熟阶段的宁夏枸杞。本研究结果表明，宁夏枸杞果实的分离力和硬度受收获时间、果实品种和成熟度的影响。不同类型的宁夏枸杞的最佳收获时间不同。观察到宁杞 1 号最好在下午和傍晚（17：00-21：00）收获，而宁杞 7 号最适合在早上（7：00-9：00）收获。
