What are the reasons for the Maya migration?

165438+ Every year1From October to May, Central America entered the dry season with little rain, and the Mayans began their pioneering season. They marched into the forest with axes made of stone. They set a fire in the forest, let the raging fire burn all the weeds, vines and dense hazel trees in the forest, then remove the residual wood after the fire and gradually open up a large field. At this time, with the arrival of June, the rainy season has come, and the Mayans have also started the sowing season. They first sharpened their long sticks with stone knives and axes, poked small holes in the blackened land with sharp sticks and poked them into chessboard-shaped blocks. Then they put a few seeds in each hole, covered the soil with their feet and stepped on it evenly. After counting the seed fields, I waited for the rain to come.

Due to the long-term cultivation of the old land, the fertility was insufficient, and the harvest began to decline. It was necessary to continuously reclaim new land, and the Mayans migrated with the transfer of land.
