用机械收获水果是一个匆匆忙忙的作业过程。在水果成熟时节,重要的是及时收获以使损耗减到最少。本文略述了用固体力学的方法测定水果的成熟程度,和根据水果抗碰伤力的不同来分检水果品种的方法和实例。 水果成熟程度评价 有经验的水果栽培者靠水果的颜色、坚实程度和形态来估计苹果或桃子的成熟程度。但是为了研究,为了检查和评价,以及为了用机械迅速分选,需 Harvesting fruits mechanically is a hurried exercise. During the fruit ripening season, it is important to harvest in time to minimize the losses. This article outlines the method of using solid mechanics to measure the ripeness of fruits and the methods and examples of sorting fruit varieties according to the different impact resistance of fruits. Evaluation of Fruit Maturity Experienced fruit growers rely on the color, solidity and morphology of the fruit to estimate the maturity of the apple or peach. But for the sake of research, for examination and evaluation, and for rapid sorting by machinery, it is required
