Collocation method for hedgerows in moderate-intense rocky desertification environment in karst area

Abstract

The invention discloses a collocation method for hedgerows in a moderate-intense rocky desertification environment in a karst area. The collocation method comprises planting processes of hedgerow selection, ridge height measurement of a sloping farmland, soil preparation, sowing and pruning, and forms a hedgerow collocation manner of interplanting different varieties of economic crops and high-quality forage on a rock ridge, a ridge slope and a ridge foot of the land in a karst rocky desertification area. According to the invention, through the hedgerow collocation manner of interplanting different varieties of economic crops and high-quality forage on the rock ridge, the ridge slope and the ridge foot of the land in the karst rocky desertification area, only a small land area is occupied; crops can be planted among ridges; planting of the hedgerows on rock ridges can significantly improve physicochemical properties of soil; water and soil loss is reduced; rocky desertification is treated; meanwhile, economic income and environmental awareness of local farmers are significantly improved; and the collocation method is more easily to be accepted by farmers in a mountainous area with more population and little land.

Description

technical field [0001] The invention belongs to the technical field of rocky desertification control in karst areas, and relates to a method for rationally utilizing ridges of sloping cultivated land in karst plateaus, in particular to a method for configuring hedgerows in medium-intensity rocky desertification environments in karst areas. Background technique [0002] At present, the methods of water and soil conservation in karst areas include the conversion of slopes to terraces that require a large investment of funds, time, and labor, large-scale conversion of farmland to forests and grasslands, and conversion of slopes to leveling projects within a certain range. However, these measures involve funds, It requires a lot of manpower and time, and it may not be recyclable, and the economic benefits are not significant, and it may even affect the amount and development of local cultivated land. The use of plant hedges to prevent and control water and soil erosion is simple...

Problems solved by technology

However, the current research on hedgerows is mainly concentrated in the Three Gorges Reservoir area with thicker soil and higher fertility, the dry-hot valley area of ​​the Jinsha River, the Loess Plateau area, and the southern red soil area, while there are fewer studies on hedgerows in karst rocky desertification areas. , how to rationally arrange hedgerows on sloping farmland with different environmental conditions of rocky desertification, make full use of the rocky ridges that cannot grow crops, increase the land utilization rate, and at the same time strengthen the stability of sloping farmland ridges, prevent soil erosion, increase Farmers' economic income, control of rocky desertification
