Any soil suitable for the growth of wheat, corn and other major dry grain crops can be planted. There is no need for water layer management during the whole growth period, and the amount of irrigation is only 10% of that of rice. Upland rice is more tolerant to drought and barren than rice, and has the characteristics of water saving with less input and more output. I. the general situation of upland rice production in the world at present, there are 18 million hectares of upland rice planting area in the world.
