During the research, this work was supported by a project funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions (No. PAPD-2018-87), the National Natural Science Foundation of China (51705212),Open Fund of Jiangsu Key Laboratory of Agricultural Equipment and Intelligent High Technology (JN2201912), the Natural Science Foundation of Jiangsu Province (BK20170553) ,Jiangsu Province "Six Talents Peak" High-level Talent Project (GDZB-085), China Postdoctoral Science Foundation (2015M581742),Jiangsu Province Postdoctoral Research Fund (1501111B), the Natural Science Foundation of Jiangsu University (14KJB460007),and the Scientific Research Foundation of Jiangsu University (14JDG029) .During the writing process, this book was supported and helped by Professor Li Yaoming, Researcher Xu Lizhang, Assistant Researcher Liang Zhenwei and other scholars. At the same time, my graduate students, such as Li Yu,Wang Meilin, Zhang Hao,Liang Yaquan, Li Pengcheng, et al. ,also gave great help in the writing process of this book. I would like to express my heartfelt thanks to all the scholars and graduate students who helped us in the writing process of this book. Due to the limited level of the author's scientific research, there are inevitably shortcomings in the writing of this book.This book is mainly about our original ideas and methods, but there are still some of the contents that are referenced by the research results of the predecessors. When this book is published, l would like to express my heartfelt thanks to the authors of all reference papers and works. I hope that I can exchange my research results of more than ten years with other scholars by writing this book. At the same time, l also hope that the contents of this book will be helpful to the study and work of enterprise designers in the agricultural engineering industry, technical workers in agricultural production, researchers in scientific research schools, and graduate students and undergraduates in schools.
