In this class, we will explore the current mechanization level of rice production in China and the equipment used for whole process mechanization of rice production. We will also discuss the solution for whole process mechanization of rice production, including an economic benefit analysis. Additionally, we will touch upon the development trend and technology prospect of the rice production industry. We will begin with an overview of the current mechanization level of rice production in China. We will discuss the challenges faced by the rice production industry and the need for whole process mechanization equipment. We will then move on to explore the various equipment used for whole process mechanization of rice production. Next, we will discuss the solution for whole process mechanization of rice production. This will include a detailed analysis of the economic benefits associated with the use of mechanized equipment for rice production. We will also explore the development trend and technology prospect of the rice production industry. Next, we will take a brief look at rice cultivation in Sri Lanka. This will help us understand how the use of mechanized equipment can be implemented in other countries and regions. By the end of this class, you will have a comprehensive understanding of the whole process mechanization of rice production, its economic benefits, and the future prospects of the industry.
