The scale is one of the important ways of industrial modernization, and it is questionable whether China's agricultural development is suitable for large-scale agricultural production models. For many years, large-scale farm production methods in the United States have proven that intensive agricultural production will cause degradation of the agricultural ecological environment and biodiversity. It is destroyed, which in turn affects food security. At present, China's per capita arable land area is only 1.52 acres, which is only the world average level, which is far lower than the U. S. per capita level, so the US ranch model is not necessarily suitable for China's development. At the same time, China's agricultural modernization started late. Compared to developed countries such as the United States, there is still a certain gap in agricultural technology and management methods. The "steps" of modernization have suddenly taken too much, and it is likely to cause a disconnection between the upper and lower levels. What this text is most likely to say next is:. ['Agricultural reform should not be rushed, but steadily.', 'Development of large-scale agricultural production models should draw lessons from abroad.', 'The scale of agricultural production should be tailored to suit local conditions.', 'Disconnection of production links is the bottleneck of large-scale agricultural development.']
