Agriculture and forestry composite treating method for channels

Abstract

The invention discloses an agriculture and forestry composite treating method for channels. The agriculture and forestry composite treating method includes: building horizontal platforms along the channels by a bulldozer, building dam-girder-like high water-retaining side ridges on the outer sides of the platforms, building gentle ridge slopes at an angle of 40-45 degrees outside the high water-retaining side ridges, building counter-slope steps on the ridge slopes every 2-3 meters, building high side slopes at outer edges of the counter-slope steps, and finally planting economic trees, crops, fast-growing trees, forage grass and the like on the horizontal platforms, the counter-slope steps and the gentle ridge slopes respectively to complete comprehensive treatment of the channels. By the aid of the agriculture and forestry composite treating method, horizontal platforms can be quickly formed along the channels, economic benefit and water and soil conservation effect are obvious, landscape ecology of ridge slope surfaces is enriched, and development of ecological economy of the channels is promoted. The agriculture and forestry composite treating method is strong in practicality, simple and particularly suitable for being popularized and used in comprehensive treatment of small-watershed channels in wide soil mountain areas.

Description

technical field [0001] The invention relates to a method for comprehensive management of ditches, in particular to a method for water and soil conservation by utilizing ditches for land reclamation. Background technique [0002] Gullies are places where surface water gathers and meets. Small watershed gullies are a landform form of gully erosion. Gullies continue to collapse under the action of severe water erosion and gravity, forming the land type with the most serious water and soil erosion in vast hilly and gully areas. The most difficult area for soil and water conservation. Gully erosion mostly occurs in the soil mountainous areas of our country, especially in the loess hilly gully area where high-density small gullies are distributed. The harm caused by gully erosion mainly includes: destroying land resources, destroying basic farmland and other facilities, exacerbating natural disasters of flood, drought, and mudslides, deteriorating the local living environment, th...

Problems solved by technology

[0003] In order to reduce the damage of gully erosion and improve the surface landscape, scientists have carried out a series of research work, such as: building check dams, valley squares, small bird's nests and other projects in the ditch, raising the base level of the ditch, and preventing the formation of upstream slopes The confluence scoured the collapsed slope; afforestation and grass planting on both sides of the ditch to reduce soil erosion on the slope have played a certain role in prevention and control, increasing agricultural land and reducing soil erosion, but the construction of the dam is huge. The cost exceeds the economic input capacity of local farmers, and related projects have to rely on the power of the government to promote. Moreover, the dam has a long time of siltation, a large area, and high maintenance costs for flood drainage and waterlogging, which cannot meet the urgent needs of local residents for cultivated land. It is also not suitable for joint use by multiple farmers with a family as the unit, and the management and utilization effects are poor
