气候高温多雨，地形平原广阔、土壤肥沃、水源充足以及交通便利和劳动力资源

The climate is hot and rainy, with vast terrain and plains, fertile soil, adequate water sources, convenient transportation and abundant labor resources are favorable factors. <br>Because climatic conditions should be the most basic among the many natural conditions, tropical cash crops will definitely not be grown in non-tropical areas. <br>As the main tropical economic crops in Southeast Asia, oil palm, rubber, cinchona, etc. are suitable for planting in plain areas-and some such as tea trees are suitable for mountainous areas with good drainage conditions, but they are not the main crops in Southeast Asia. <br>Among these natural conditions, the investment cost of climate and topography transformation is too large (————-climate transformation is commonly used in greenhouses, and terrain is commonly used in terraces), which has become the first choice for growing tropical cash crops. Soil improvement is easier, and Southeast Asia, which is wet and rainy, has superior water conditions.
