The similarities between the two countries' corn belts are as follows: the agricultural geographical types of China corn belt and American corn belt are the same, both of which are commodity grain agriculture with large production scale, high mechanization and high commercialization; Both places have superior natural conditions suitable for agricultural development, with flat terrain, fertile soil, high temperature and rainy summer, suitable for corn planting K; The planting structure of the two places is mainly corn, and the proportion of corn area is above 50%; The yield of corn is very high.
Difference: Different management modes. Farms in China's corn belt are large state-owned farms, while farms in the United States are generally family-run. The degree of regional specialization, management specialization and modernization of American corn belt is higher than that of China. In addition, the latitude of corn in China is relatively high, the natural conditions are relatively poor, and the yield per unit area is relatively low, which is mainly related to the monsoon climate. )
In the answer:
1 yes, the American corn belt is 37 N ~ 45 N and 42 N ~ 46 N
That's right. See the lesson plan.
3 No, specialization is not as high as that of the United States, but intensification lacks data support.
It must be wrong. There are floods and droughts in the northeast, and there are more dry fields.
