Carbon-sink-increasing planting method for rocky desertification comprehensive treatment of karst region

The invention provides a carbon-sink-increasing planting method for rocky desertification comprehensive treatment of the karst region. The carbon-sink-increasing planting method comprises the following steps: adopting a stereoscopic planting technology; planting an industrial crop with high growth suitability and high carbon sink benefit; adopting matched planting of forage grass and the industrial crop such as arbor and shrub; adopting a bunch planting and hole sowing technology to reduce soil carbon pool loss; planting a perennial plant to reduce soil carbon pool loss, and promote returning of sloping farmland into forest and grassland; adopting a fertilizing technique of slowly controlled release of fertilizers and soil testing, and planting legume forage, so as to reduce agricultural carbon emission caused by chemical fertilizer use. According to the method provided by the invention, based on rocky desertification comprehensive treatment and vegetation recovery, the carbon sequestration and carbon sink in
