Top1. Introduction
China is a big agricultural country, and its cultivated land accounts for about 10% of the world's cultivated land, providing about 30% of the world's food. In the course of more than 20 years, China has gradually entered the stage of modernization. Facing the growth of population and the acceleration of globalization, the modernization of agriculture is essential. To improve the international competitiveness of agriculture and give priority to the development of rural economy is the main task of China at this stage. China should attach importance to the development and research of high and new technology, better realize the goal of agricultural modernization and improve the competitiveness.
The development of agriculture in foreign countries has mainly experienced three stages: 1970s, 1980s and 1990s.Before the 1980s, it mainly focused on the collection of agricultural data and the expansion of agricultural information database. Since the 1990s, the focus has shifted to the processing and application of information, and the development of agriculture through the use of information systems. The agricultural development of European and American countries is relatively rapid and has entered the stage of industrialization. Most family farms, rural growers and farms in the United States are equipped with electronic equipment. Through the network platform to obtain the latest agricultural policy, machinery and equipment, weather forecast and other information. You can also sell or purchase raw materials of crops through the network platform. You can know the latest market price and supply-demand relationship at home. Improve agricultural production efficiency (Heng, Z. 2020).The United States has formed a three-level agricultural information platform composed of States, regions and countries. All departments work together to provide farmers with efficient and accurate data to facilitate agricultural production. For example, the U.S. Department of agriculture has established an agricultural information dissemination system, which receives agricultural information and publishes market price and agricultural technology data on time. The data are collected through the Agricultural Statistics Bureau and then transmitted to farmers by computer transmission system (Qiang, Y. Caixia, G et al 2018). Japan's agricultural development is relatively backward, in the 1960s chose the computer agricultural technology reform, since then agriculture has been rapid development. Through computer technology to promote the development of agriculture, improve the enthusiasm of farmers in production, further stimulate the progress of Agricultural Technology (Wei, Y., Wang, X, et al 2018).We should speed up the process of agricultural development through information collection system and communication system. Japan has set up a special agricultural information system to disseminate new technologies, products and policies on agriculture, so as to achieve information popularization and resource sharing. Propaganda and education should be carried out in all aspects of production to promote the development of industrial chain and promote the progress of new agricultural economy. The level of machine income has also increased steadily, reaching about 20%.China's agricultural equipment has been developing rapidly. Taking Zhejiang Province as an example, the agricultural facilities in the province are basically complete in the early 21st century. According to incomplete statistics, there are about 68.25 million agricultural tractors, including large and medium-sized and small-sized ones, about 180000 transport equipment and about 1400 harvesters. In terms of crop production, there are 7.6 million tea processing machines and about 350 grain drying machines, with a total of 4.23 million tons of dried grains. In terms of agricultural sowing, there are 195 mechanized rice transplanters, 400000 irrigation machines and 20000 spraying machines. At the beginning of the 21st century. By the end of the 20th century, more than 8.5 million mu of agricultural machinery had been used in the province. In addition, crop cultivation and mechanical facilities have also formed a certain scale. There are mainly two kinds of cultivation facilities, namely, plastic multi span greenhouse and plastic simple greenhouse, occupying more than 2 million and 600 000 square meters respectively in the province, and there are more than 200 greenhouse mechanical facilities (Li, C., Tang, Y. et al 2020).In recent years, the level of Agricultural Mechanization in China is developing continuously, but it is still far behind the technical level of developed countries. It will take a long time to catch up with the development pace of developed countries(Duau, J., Zhang, L. et al 2018).
