On a global scale, why is the traditional grain planting industry in tropical areas underdeveloped?

Tropical aquaculture of aquatic animals and plants on the beach is also of great economic value. Sea salt, seaweed, shellfish and fish are not necessarily worse than the income from growing food. The technical content is also quite high. It is not suitable for planting rice, millet, corn, millet and other food crops. In the market, the prices of many of our agricultural products are upside down with those of international agricultural products, and the prices of many imported agricultural products are cheaper than those of similar domestic products, which leads to the weak position and backwardness of domestic agricultural products in the market competition.

The annual solar radiation difference in tropical areas near the equator is positive, which makes the tropical climate mostly high temperature, including tropical rain forest climate, tropical grassland climate, tropical monsoon climate and tropical desert climate. Tropical grassland climate-suitable for the development of animal husbandry; Sufficient light and hot water can reasonably develop planting, but the characteristics of dry and wet seasons are easy to bring drought and flood disasters. I think the natural resistance is too great (that is, the natural resistance is too great), especially the resistance of the tropical region to the cultural process. We know that the higher the reasonable human and cultural process, the better the development of this region. Therefore, the development of tropical areas lags behind the huge resistance within the tropical rain forest, and the process of developing human beings is not easy. Therefore, agriculture, as the cornerstone of development, has no good development place, so most tropical areas are short of food, and fruits have higher economic benefits. Needless to say, everyone knows that the current grain market is very stable, and it depends on it. But fruit is different, it has high economic benefits and strong liquidity.

It is also true that the fruit industry in Guangxi has developed rapidly and ranked higher and higher in the country. According to the statistics of the fruit department, in 20 18, the fruit area in Guangxi reached170,000 mu, and the total output195,000 tons was close to 20 million tons. In my hometown, the large-scale planting of fruits is not only strongly guided and supported by the local government, but more importantly, the local government will do everything possible to attract merchants to buy fruits and do a good job in local fruit sales channels.
