Guide: the United States is one of the countries with the most developed agriculture and the most advanced technology in the world. Highly developed capitalist commodity production prompted the United States to take the lead in the world in the 1940s and realize the mechanization of grain production at the earliest. In the late 1960s, the mechanization level of grain production was even higher, reaching the goal of land cultivation and consolidation

the United States is one of the countries with the most developed agriculture and the most advanced technology in the world. Highly developed capitalist commodity production prompted the United States to take the lead in the world in the 1940s and realize the mechanization of grain production at the earliest. In the late 1960s, the mechanization level of grain production was even higher, reaching the mechanization of the whole process from land ploughing, land preparation, sowing, field management, harvesting, drying and so on; In the early 1970s, the mechanization of cotton, sugar beet and other cash crops from planting to harvesting was completed. At present, it still maintains the world's advanced level in planting, industrialized livestock and poultry breeding, facility agriculture, agricultural product processing and other aspects. A high level of mechanization and scientific and effective management have greatly improved agricultural labor productivity. In 1987, the per capita output value of agricultural labor in the United States reached US $55300, which was four times that of many other developed countries in Ningbo at that time, ranking first in the world. Agricultural mechanization has effectively promoted the rapid development of (2) the local stress-strain method of American agriculture, which is mainly used to calculate the low cycle fatigue life dominated by plastic deformation, and also made the United States become the world's largest exporter of agricultural products

the agricultural machinery produced by large multinational agricultural machinery companies such as John Deere company, case vanguard company and Ford company (tractor) in the United States has high productivity, advanced performance, high degree of standardization, serialization and generalization, good manufacturing quality, reliable use, convenience and comfort, which is the world's advanced level. It is widely used in China and the world and is very popular with users

in order to protect the agricultural ecological environment, realize the sustainable development of agriculture, make the most effective use of and save agricultural resources, improve agricultural labor productivity and commodity rate of agricultural products, and maintain the competitiveness of agriculture in the world, the United States pays special attention to the development of agriculture and agricultural modernization. American industries such as machinery, fertilizer, aerospace and so on have provided a large number of agricultural machinery, fertilizer, agricultural aircraft and other advanced means of production and equipment for agriculture, making agriculture a major export industry for decades. The United States attaches great importance to the promotion and use of agricultural conservation tillage technology and machinery. The price advantage is no longer through long-term efforts. At present, the proportion of conservation tillage (calculated according to the standard of 30% crop residue coverage) has reached 30%-40% for soybeans and 25% for corn. The actual surface crop residue coverage is less than 30%, and the cultivated area close to the standard is much larger than the above number. In order to meet the needs of agricultural protective farming technology, agricultural machinery manufacturers such as John Deere company and case world company in the United States have provided agriculture with a large number of agricultural machinery with less tillage and no tillage for protective tillage

in recent years, the United States has begun to adopt high and new technologies such as satellite global positioning system monitoring operations on agricultural equipment such as grain combine harvesters, spray, seeders, etc. Agriculture has shown a trend towards precision agriculture
