Problems solved by technology

However, the slope cutting project changes the boundary conditions of the slope, which reduces the stability of the slope. When the cohesion of the soil is high, it is easy to cause the failure of the slip surface starting from the slope. The cohesion of the soil is small, and the slip is prone to occur failure from the top of the slope
However, if slope protection projects such as shotcrete slope protection, lattice frame vegetation slope protection, masonry retaining wall, and frame retaining wall are used, the manpower and material resources invested are large, and it is difficult to pay the treatment cost of many erosion ditches economically.

Embodiment 1

[0042] 1. After Zhaojiayao Village, Xuetian Township, Tuquan County, Xing'an League, Inner Mongolia, a 500-meter-long erosion ditch was selected, and the vertical ditch slope with a length of 100 meters was greened. The fish scale pits were dug along the ditch slope perpendicular to the trend of the erosion ditch. The length, width and height of the fish scale pits were 1.5 meters, 0.6 meters, and 0.5 meters. A total of 15 rows of fish scale pits were dug, with 30 fish scale pits in each row. Plant Pinus sylvestris sylvestris in the pit, and caragana on the stems of the pit. Set gabion valley squares in the erosion ditch. A total of 10 gabion valley squares are set up at a distance of 500 meters, with a distance of about 50 meters, depending on the direction of the erosion ditch and the conditions of the vertical slope, so as to ensure that the vertical slope of the erosion ditch does not collapse.

Abstract

A method for treating soil erosion gully by planting trees on gully slopes and water conservation project relates to a method for treating soil erosion gully by planting trees, wherein there are erosion gullies with relatively perfect water conservation measure on the slope surface within a water catchment range, such as water conservation forests on the slope surface, fish scale pits, river closure gullies and other water retaining works, and arranging check dams in the gullies to ensure that the vertical gullies and slopes of the erosion gullies do not collapse; secondly, selecting the sowing or planting time, performing punch point location on the vertical trench slope with the slope of 85-90 degrees, covering the soil with a sunshade net after sowing, supporting the sunshade net with the height of 20-40cm on the vertical wall. Water and fertilizer management is the same as that of conventional management in the seedling and growing stages of shrubs and trees, and a water-retainingagent can be applied appropriately under the condition of less precipitation. At that same time, the invention solves the problem of water demand for plant cultivation in erosion gullies in areas where water wagons are difficult to climb mountains, the growth of plants is ensured in water-lack areas, planting trees on upright gully slopes plays an important role in soil consolidation and prevention of slope collapse, it also reduces the flow rate of rainwater and the damage to grain mills to a certain extent.

Description

technical field [0001] The invention relates to a method for controlling soil erosion ditch, in particular to a method for controlling soil erosion ditch by planting trees on the slope of the ditch and assisting soil and water conservation projects. Background technique [0002] Soil erosion ditch is mainly formed by water force, wind force, freeze-thaw erosion. According to the first national water conservancy census, the Songliao Water Conservancy Committee of the Ministry of Water Resources conducted a comprehensive investigation of the gullies formed by soil erosion, especially gully erosion, in the black soil area of ​​Northeast China. Heilongjiang Province has the largest number of 115,500, Liaoning has the least number of 47,200, Inner Mongolia Autonomous Region and Jilin have 70,000 and 63,000 respectively. The total area of ​​erosion channels in the black soil region of Northeast China is 3648.42 km 2 , with a total length of 195,500 km and an average gully densit...
