Cactus, pitaya and zanthoxylum bungeanum matched planting method in karst stony desertification region

Abstract

The invention discloses a cactus, pitaya and zanthoxylum bungeanum matched planting method in a karst stony desertification region. The method comprises steps as follows: land separation and land preparation: sandy soil in a karst moderate stony desertification plateau canyon area at altitude of 600-700 m and slope of 30-50 degrees is selected, and plots in a terrace type line shape along the slope contour lines are obtained by preparation; seed selection and planting: cactus and pitaya stems and leaves at the young stage and injury-free and disease-free zanthoxylum bungeanum seedlings are selected as seedlings; two rows of crops are planted on each step of ridge, cactus is planted outside, and the pitaya and the zanthoxylum bungeanum are inter-planted inside; water and fertilizer application; the crops are watered sufficiently during planting, and water is supplemented when the soil water content is lower than 40% at the growth stage; field management: complementary planting of seedlings, weed control, pruning and pest control are performed at regular time; harvesting. According to the method, the problems of low land space utilization rate, poor ecological restoration effect, poor economic benefits of farmers in the stony desertification region due to the fact that karst stony desertification region treatment mainly depends on planting of lawns or single economic plants are solved.

Description

technical field [0001] The invention relates to the field of ecological management of rocky desertification, in particular to a method for planting cactus, dragon fruit and Chinese prickly ash in a karst rocky desertification plateau canyon area. Background technique [0002] The vegetation in the rocky desertification area is severely damaged, the bedrock is exposed, the soil is barren, and the surface presents a landscape similar to desertification. According to the "China·Karst Region Rocky Desertification Bulletin" issued by the State Forestry Administration and Grassland Bureau in 2018, as of 2016, the area of ​​karst rocky desertification in my country was 10.07 million hectares, accounting for 22.3% of the karst area, involving Yunnan, Guizhou, Sichuan and Chongqing in Southwest China. Since the eight provinces and cities are located in the upper reaches of important water systems such as the Yangtze River and the Pearl River, the ecological location of the rocky deser...
