specific Embodiment approach 1

[0016] Specific implementation mode one: a kind of flat ditch reclamation erosion ditch control method of the present embodiment is carried out according to the following steps:

[0017] 1. Slope cutting: carry out slope cutting on the slopes on both sides of the ditch, and at the same time, build terraces on the slopes. The width of the terraces is 200cm-500cm, and the height of the terraces is 100cm-120cm;

[0018] 2. Planting vegetation: plant economic forests on terraced fields, planting density: row spacing is 2m~4m, plant spacing is 2m~4m;

[0019] 3. Construction of drainage facilities: Dig drainage ditches on the terraced fields in the direction perpendicular to the ditches, then lay a layer of sand base in the drainage ditches, and then put the prefabricated U-shaped grooves into the drainage ditches as drainage ditches I In the channel, the setting density of the drainage ditch I is to set one along the channel no more than 10m, the width of the drainage ditch I is 2...

specific Embodiment approach 2

[0024] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the width of the terraced fields described in step 1 is 300cm-400cm. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0025] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that: the width of the terraced fields is 350 cm. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a method for controlling erosion gullies for land reclamation in flat gullies. The invention relates to a water and soil conservation engineering technology, in particular to a method for controlling erosion ditch for land reclamation. The purpose of the invention is to solve the problems of slope cutting and land occupation, low land utilization rate and no consideration of channel drainage in the current treatment method of erosion ditch. Methods: 1. Slope cutting; 2. Planting vegetation; 3. Building drainage facilities; 4. Building water storage facilities; 5. Building ditch bottom drainage facilities. The present invention changes the slope surface of the original barren ditch into a terraced field surface, which increases the stability of the slope. At the same time, economic forests are planted on the field surface, which can generate additional economic benefits, increase grain production, and increase farmers' income; supporting drainage facilities It can effectively divert the incoming water from the slope, fully reduce the erosion of the field surface by the incoming water on the slope, and enhance the stability of the slope; Rainwater is stored for use in field crop irrigation or spraying.

Description

technical field [0001] The invention relates to a water and soil conservation engineering technology, in particular to a method for controlling erosion ditch for land reclamation. Background technique [0002] my country is one of the countries with the most severe soil erosion in the world, and gully erosion accounts for a large proportion of soil erosion. The development of erosion gullies has led to the encroachment and cutting of good fields, and the fragmentation of large areas of land, the damage of roads, the reduction of arable land, the impact of machine farming operations, and the decline in grain production, leading to food supply crises, threatening national food security, and threatening people's life and production safety. . Therefore, the control of erosion gullies is an important measure to control soil erosion, ensure food security, protect the ecological environment, and benefit the country and the people. [0003] Erosion ditch control usually adopts mea...
