What are the agricultural regional types and production characteristics along Tonle Sap Lake?
Features:
(1) Small-scale agriculture. Rice production takes the family as the unit. Due to the shortage of arable land per capita, there is very little farmland cultivated by each household. The rice planting area of each household in southern China is generally less than 1 hectare.
(2) The output per unit area is high, but the commodity rate is low. 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, and restricted by traditional concepts and economic level, farmers keep a considerable part of the collected rice for their own use, while the rice sent to the market for sale is limited.
(3) The level of mechanization and technology is 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, the overall mechanization and scientific and technological level are still relatively low; The mechanization level of rice production in other Asian countries is still very low except Japan, which has made great progress in the mechanization of rice fields.
(4) The scale 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 the government needs to invest heavily and organize water conservancy projects.
