There are 14,200 hectares of dry land in Guangxi, accounting for 36.6% of the total arable land, while 70% of dry land is concentrated in the mountainous counties of Baise, Nanning, Hechi and Liuzhou.

With less fertilizer, extensive farming and more pests and diseases, the output and output of dry land crops are very low. In order to change this situation, the Department of Agronomy, Department of Farming, Department of Agriculture, Animal Husbandry and Fisheries Department and brother unit jointly established a dryland collaborative research group, in Jingxi, both
