Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of the existing low mountain and hilly area reclaimed along the slope of the mountain, because the soil layer is thin (<30cm), the slope is relatively large (more than 5 °), water and soil loss causes the water stress of the cultivated land to increase, the topsoil is peeled off, and the ditch is eroded. It can damage the farmland, restrict the operation of agricultural machinery, cause the productivity of the farmland to drop, and even make it difficult to continue farming, and provide a method of water and soil conservation with double ridges

specific Embodiment approach 1

[0053] Specific implementation mode one: combine figure 1 , a method for water and soil conservation with double ridges in this embodiment, specifically completed according to the following steps:

[0054] 1. Determination of the specifications of the double ridge belt: build two ridges to ensure parallelism, and the sections of the two ridges are the same, the top width of the ridge is a, the unit is m, the bottom width of the ridge is A, the unit is m, the height of the ridge is H, the unit m, distance B between two ridges, unit m;

[0055] The ridge top width a=0.5m described in step one; the bottom width A=1.7m of the ridge described in step one; the ridge height H=0.6m described in step one; the ridge height H=0.6m described in step one; The distance between two ridges B=1m;

[0056] 2. Ridge line setting: at the highest point in the middle of the sloping farmland, set the first line according to the ratio of 1 / 200 to 1 / 300, take the big bend as the trend, and the small...

specific Embodiment approach 2

[0097] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the seedlings described in the step five are cypress, Aralia longifolia, raspberry, Acanthopanax short stems, black currant, wolfberry, hazelnut or Amorpha. Others are the same as in the first embodiment.

[0098] When the seedlings are Acanthopanax short stems, the planting distance is 0.5m.

[0099] When the seedlings are black currants, the planting distance is 0.5m.

[0100] When the seedlings are hazelnuts, the planting distance is 1.5m.

[0101] When the seedlings are Aralia changbai, the planting distance is 1.0m.

[0102] When the seedlings are cypresses, the planting distance is 0.4m×0.4m.

[0103] When the seedlings are Amorpha fruticosa, the planting distance is 0.2m×0.2m.

[0104] When the seedlings are raspberries, the planting distance is 1.0m.

specific Embodiment approach 3

[0105]Specific implementation mode three: the difference between this implementation mode and specific implementation mode one or two is: in step 4, after the annual autumn harvest or before spring field preparation and sowing, use an excavator to set the spacing B of two ridges in step 1 to build parallel Ridge. Others are the same as in the first or second embodiment.

[0106] Adopt the following examples to verify the beneficial effects of the present invention:

Abstract

The invention relates to a double-ridge area water and soil conservation method, and relates to the technical field of agricultural production. The invention specifically relates to a slope surface soil erosion control water and soil conservation method. In existing slope farmlands reclaimed along hills in low mountain and hilly areas, soil layers are thin, and soil erosion made farmland water stress severer. Topsoil is stripped, and erosion gullies damage the farmlands. Agricultural machine operation is restricted, such that farmland productivity is reduced, or even it is difficult to continue farming. The invention aims at solving the above problems. The method has the following steps: 1, a double-ridge area specification is determined; 2, ridge area route is set out; 3, double-ridge area spacing is determined; 4, the double-ridge area is built; and 5, double-ridge area plants are planted. The double-ridge area water and soil conservation method provided by the invention is suitable for soil erosion control in low mountain and hilly area slope farmlands with severe soil erosion problems.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a water and soil conservation method for preventing and controlling slope surface water and soil loss. Background technique [0002] Soil erosion is one of the major disasters in the world. It destroys land resources, causes productivity decline and siltation; consumes limited water resources, causes disasters such as drought and flood, causes deterioration of ecological environment, and seriously threatens human survival and development. issues of general concern. The problem of soil erosion exists to varying degrees in both developing and developed countries, and it tends to continue to deteriorate. According to the estimates of the Food and Agriculture Organization of the United Nations, the area of ​​land with soil erosion in the world is as high as 25 million square kilometers. 2 , accounts for 16.7% of the total land area, and loses 26 billion ...
