In the northeast, why can't we develop agricultural mechanization like the United States?

The comprehensive mechanization level of main crops in Heilongjiang Province has reached 96.8%, ranking first in the country. At present, in the process of field operation, the level of mechanical tillage has exceeded 99.2%, and the degree of mechanical sowing and mechanization has exceeded 97.5% and 88.5%. In 20 17, the total power of agricultural machinery in Heilongjiang province was 58138,000 kilowatts, and the number of tractors reached165,000, including 36,000 tractors with horsepower above 10. The structure of agricultural machinery and equipment has been continuously optimized, and high-standard agricultural mechanization operations have achieved 100% remote automatic detection. The rapid development of agricultural mechanization has played an important role in increasing agricultural production and farmers' income in Heilongjiang Province.

Not only because of the high degree of mechanization, but also because of the modern mechanical agriculture of American agriculture. American agricultural machinery is not only numerous and varied, but also many technologies are being patented. Agricultural machinery is equipped with GPS and satellite positioning system, and some farms have formed a "computer comprehensive adaptive production" mode that integrates mayor/market information and production parameter information (climate, soil, seeds, agricultural machinery, chemical fertilizer, pesticides, energy, etc.). ), capital information and labor information. In the process of crop growth, according to the change of microclimate in different regions, adaptive fountains, fertilizers and drugs are applied to ensure good growth conditions, so that agricultural production can form a virtuous circle, minimize risks and maximize profits.

American farmers are very skilled in agricultural machinery. Many agricultural machinery are bought, modified and even designed by farmers themselves. Most American pilots don't want to work in airlines, preferring to fly agricultural planes. Doing farm work is not decent or even cool. We usually think that we can't develop large-scale farms in China, mainly because of our terrain and the reality of few people. If we study geography, we know that the terrain in China is complicated. About 66% of cultivated land in mountainous areas, hills and plateaus is distributed in mountainous areas, hills and plateaus, and only about 34% of cultivated land is distributed in plains and basins.

The first-class cultivated land area only accounts for 4 1.33% of the total cultivated land area, and the distribution is still uneven. Most of the cultivated land is concentrated in the eastern region, and there is actually not much cultivated land suitable for large-scale planting. Therefore, mechanized large farms cannot be popularized in most areas of China. More people can understand this better. At present, China's population is1400 million, including 750 million in agricultural registered permanent residence, and about 650 million people are actually engaged in agricultural production. With so many farmers, how much arable land does our country have? The total cultivated land area in China is 65.438+0.82574 billion mu, and the per capita cultivated land area is less than 654.38+0.35 mu, which is less than 40% of the world average. This figure is 9 acres in the United States. This kind of national politics determines that it is impossible for us to develop large farms like the United States.
