(2) The central plains of the United States have a temperate continental climate; Agricultural products in southeast Asian monsoon paddy fields are mainly self-sufficient; The agricultural science and technology level of American commodity grain is high; Southeast Asia monsoon paddy field agriculture is family-based and managed by small farmers.
So the answer is:
(1) tropical monsoon climate, high temperature and rainy, suitable for rice growth; Chao phraya plain, low and flat, is conducive to farming; Deep soil layer and fertile soil; Close to Chao Phraya River, there are abundant irrigation water sources.
(2)
Climatic products are mainly used in the operation of science and technology. American commodity grain agriculture (temperate continental climate) commodity agriculture (high level of science and technology) family farm, large-scale southeast Asian monsoon paddy field agriculture tropical monsoon climate (subsistence agriculture) rely on traditional experience (small-scale peasant management)
