Problems solved by technology

People living in hills and highlands open up wasteland and farm fields on steep slopes for agricultural production, which further leads to the formation of new erosion ditches; the excavation and filling of buildings such as dams and spillways disturb the original landform and destroy water and soil conservation facilities. , causing water and soil loss; the mining of stockyards, the stacking of waste residues, especially the random dumping of waste residues into rivers, affects flood drainage
At present, predecessors have done a lot of water and soil management in the Yellow River Basin, with some small achievements, but the condition of the river basin has not been fundamentally changed

Embodiment 1

[0033] A control method for the small watershed of the Yellow River, comprising the steps of:

[0034] (1) multiple holes are made on the hillside of the watershed, the depth of the hole is 27cm, and the diameter is 6cm, and the fallen leaves that are crushed are put into the bottom of the hole, and the depth of the fallen leaves is 18cm, and the elm trees are densely planted with elm seeds, and the elm wall is pruned into, used for keep water and soil;

[0035] (2) Make a plurality of holes at the bottom of the Shuichong ditch, the depth of the holes is 20cm, the distance between the holes is 22cm, and the elm branches are cut for water blocking;

[0036] (3) build dikes and dams at water gullies that need to be controlled, and deposit sand and soil. Described dikes and dams are barrel-shaped for elm branches to be woven into, and soil is filled in the buckets, and multiple buckets are connected with iron wires to form.

Embodiment 2

[0038] A control method for the small watershed of the Yellow River, comprising the steps of:

[0039] (1) multiple holes are made on the hillside of the watershed, the depth of the hole is 30cm, and the diameter is 5cm, and the fallen leaves that are crushed are put into the bottom of the hole, and the depth of the fallen leaves is 20cm, and the elm trees are densely planted with elm seeds, and the elm wall is pruned into, used for keep water and soil;

[0040] (2) Make multiple holes at the bottom of the Shuichong ditch, the depth of the holes is 25cm, the distance between the holes is 20cm, and the elm branches are cut for water blocking;

[0041] (3) build dikes and dams at water gullies that need to be controlled, and deposit sand and soil. Described dikes and dams are barrel-shaped for elm branches to be woven into, and soil is filled in the buckets, and multiple buckets are connected with iron wires to form.

Embodiment 3

[0043] A control method for the small watershed of the Yellow River, comprising the steps of:

[0044] (1) multiple holes are made on the hillside of the watershed, the depth of the hole is 33cm, and the diameter is 4cm, and the fallen leaves that are crushed are put into the bottom of the hole, and the depth of the fallen leaves is 22cm, and the elm trees are densely planted with elm seeds, and the elm wall is pruned into, used for keep water and soil;

[0045] (2) Make multiple holes at the bottom of the Shuichong ditch, the depth of the holes is 30cm, the distance between the holes is 18cm, and the elm branches are cut for water blocking;

[0046] (3) build dikes and dams at water gullies that need to be controlled, and deposit sand and soil. Described dikes and dams are barrel-shaped for elm branches to be woven into, and soil is filled in the buckets, and multiple buckets are connected with iron wires to form.

Abstract

The invention relates to a treatment method for a small watershed of the Yellow River, which comprises the following steps of: digging a plurality of holes or shallow ditches on a hillside of the watershed, and planting elms with elm seeds; punching a plurality of holes in the bottom of the water gully, and cutting elm branches for blocking water; a dam is constructed in the gully needing to be treated, and sandy soil is deposited. The elm branches have opposite branches, barbs can be formed after pruning, the elm branches are not prone to retreat after being inserted into the holes, the flexibility of the elm branches is very high, the elm branches are not prone to being broken, and the elm branches can be used for blocking water and reducing impact of the water; as the impact force of water is reduced, a dam can be constructed behind the elm branch forest for silting soil, according to the method, water and soil loss can be effectively reduced through small-hole elm planting afforestation, elm branch cutting water blocking and dam construction sandy soil silting, materials are convenient and easy to obtain, the price is low, the planted elm trees can be used for cutting water blocking and dam construction silting soil, and the method is suitable for popularization and application. Raw materials can be recycled, and elm seeds are easy to collect.

Description

technical field [0001] The invention belongs to the technical field of watershed control, and in particular relates to a control method for small watersheds of the Yellow River. Background technique [0002] At present, the soil erosion in the Yellow River Basin in my country is serious, mainly due to hydraulic erosion, which is mainly caused by the broken geological structure, severe loose soil texture, and the destruction of ecological vegetation, which has become the chief culprit of soil erosion. At present, the Yellow River Basin is dominated by water erosion, accompanied by gravity and wind erosion such as soil and sand sinking, collapses, and landslides, turning the original clear river into a turbid "sand river". [0003] At present, soil erosion in the Yellow River Basin is caused by the dual effects of natural factors and human factors, and the irrational planning and unreasonable development of natural resources by human beings, resulting in serious damage to soil...
