natural cause
climate
Mainly distributed in tropical, subtropical and temperate monsoon climate zones, with high temperature all year round or in summer; Most of them are concentrated in areas with annual precipitation above 800 mm, with abundant precipitation, sufficient water and heat resources and convenient irrigation.
zone
Mainly distributed in river alluvial plains, deltas and basin hills, with flat terrain.
land
The soil is deep and fertile.
Socio-economic factors
Labor force
The production process of rice planting is complex, labor-intensive and requires a lot of labor. East Asia, Southeast Asia and South Asia are densely populated and rich in labor.
Cultivated land per capita
The main rice planting industries in Asia are densely populated, with less arable land per capita and high rice yield per unit area. Planting rice can alleviate the population's pressure on land and demand for food.
Production habit
Rice planting in East Asia, Southeast Asia and South Asia has a long history and rich traditional experience.
partial eclipse
Rice is the main food that local people like.
trait
1, small-scale farming. Rice production in monsoon paddy field is based on family. Due to the shortage of cultivated land per capita, every household has little cultivated land. The paddy field cultivated by every household in southern China is generally less than 1 hectare.
2. High yield per unit area. Farmers intensively cultivate in the fields, which makes the yield of rice per unit area higher. However, due to the small scale of production, the total output of rice per household is not large.
3. The commodity rate is low. Restricted by traditional ideas and economic level, farmers keep a considerable part of the collected rice for their own use, but the rice sent to the market for sale is very limited.
4. The level of mechanization and science and technology is relatively low. Farmers generally engage in manual labor. Although electric irrigation threshing has developed rapidly in recent twenty years and the use of chemical fertilizers and pesticides has gradually increased, on the whole, the mechanization level and scientific and technological level of monsoon paddy field agriculture are still relatively low.
5. The amount of water conservancy projects is large. Irrigation is the basis of rice production. Frequent floods and droughts in monsoon region pose a great threat to rice production. Small-scale farmers are unable to build water conservancy projects, so they need a lot of government investment to organize water conservancy projects.
The above is for reference only, I hope it will help you.
