Download or read book Mechanical Harvest of Fresh Market Apples written by Zhao Zhang and published by Springer Nature. This book was released on 2021-11-02 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the progress, changes, and evolvement for apple mechanical harvest during the past decades, which include, but not limited to, bulky harvest method, harvest platform, apple infield sorting, and harvest robotics. Though there are significant progresses in apple harvest robotics, there still is a long way ahead before its practical applications, with existing and potential bottlenecks described in this book. Hence, other researchers would take advantage of this book to have a hint of the apple mechanical harvest history and state-of-the-art progress, so that they can find the room for their new research. This book targets senior undergraduates and more importantly graduate students in the field of agricultural engineering, sensing, automatic, and robotics.

This book was released on 2020 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fresh-market apple is one of the high-value agricultural produces in the United States and Washington. These apples are harvested manually worldwide, which requires a large seasonal workforce. Due to uncertain availability and rising cost of labor, the need for mechanical harvesting technologies has become critically important. Shake-and-catch harvesting technology has been studied to address this issue. Major challenges for mechanically harvesting fresh-market fruit include insufficient fruit removal, high fruit damage, and low labor productivity. As a way to address these challenges, this study focused on understanding canopy responses to the harvesting system through employing a supervised machine learning algorithm. Specifically, it aimed at identifying the most relevant canopy parameters influencing the fruit removal during mechanical harvesting. Based on the analysis of apples 'harvested' mechanically and those that remained on the trees after harvesting operation, fruit load, branch diameter, and shoot length/diameter were found to be the canopy parameters highly relevant to the success of mechanical harvesting techniques. Field tests, therefore, revealed that the pruning strategies have a remarkable influence on fruit removal efficiency. It was found that, to maintain a minimum removal efficiency of 85%, the shoot length should be less than 15 cm or S-index (the ratio of shoot diameter to length) should be >0.03.This study also included a comprehensive evaluation for comparing different harvesting systems based on multi-year/cultivar field trials. The results showed that the semi-automated system was more effective (fruit removal efficiency of 90%) compared to the hand-held (87%) and the manually operated hydraulic systems (84%). To further advance the automated machine operation, a machine vision (deep learning-based) system was developed for detecting and localizing tree trunks and branches, which achieved an intersection over union (the ratio of overlapping to total area) of 0.69 in trunk/branch detection. Polynomial curves were then employed for fitting the branches/trunks through the detected segments, which was used in estimating shaking locations on those branches. This research served as a basis for optimizing and advancing shake-and-catch harvesting technologies on fresh-market apple harvesting, which is expected to make a huge, positive impact on the long-term economic sustainability of apple industry.

Available in PDF, EPUB and Kindle. Book excerpt: This is a revised and updated edition of the book Tree Fruit Production, first published in 1959 and extensively revised in the second edition in 1972. Considerable advances have been made in recent years in the scientific production and handling of deciduous tree fruits in North America. This third edition brings together in up-to-date usable text book form the essence of pertinent research and practical experience on the subject. Although the principles involved in the different operations of orchard management, such as pruning, soil management, fruit thin ning, and harvesting remain constant, practices and techniques have been undergoing considerable change. Economic and social changes have been brought to bear in altering the approach to such aspects of pomology as tree size, plant density, mechanical harvesting, pest control and irrigation. Greatly increased costs of production have swung the emphasis of attention toward the wider use of organic chemicals in the orchard. Growth regulating substances are finding a place in the orchard, not only for fruit thinning, preharvest drop control and weed suppression, but also for other purposes such as promotion of early flowering, tree train ing, pruning and the advancement and extension of the harvest season. The trend toward the smaller, more easily and economically managed apple tree which began slowly some three or more decades ago and increased rapidly in subsequent years is now complete.

Available in PDF, EPUB and Kindle. Book excerpt: Automation in agriculture is made possible by the integration of advanced agricultural technology and precision agriculture management. This book, uniquely, will focus on applications of automation to the important industry of tree fruit production. Written by experts in agricultural automation technology from around the world, chapters in this book cover topics such as automated tree fruit production systems, plant stress sensing and high-throughput phenotyping in precision horticulture, the economics of automation in tree fruit production, light interception sensing systems for canopy management, precision irrigation and water management, precision technologies for pest and disease management, opportunities for the application of robotics in tree fruit production, and the mechanical harvesting and handling of fruit crops. The book is a representative, concise overview of the variety of technologies currently being applied to tree fruit crops around the world and the challenges faced by engineers and farmers that these technologies raise. It is aimed at researchers and graduate students of agriculture systems, agricultural and biological engineering, crop and soil sciences, horticulture, precision agriculture, and other relevant disciplines. It will also be of use to agriculture consultants, engineers, and other professionals such as agricultural equipment manufacturers and management professionals who use precision agriculture technologies.
