Embodiment 1

[0023] (a) Keep a section of hillside in the original state between two adjacent fields with a width of 2m and a depth of 1m, which is called a slope separation, and excavate a trench with a width of 1.5m and a depth of 1m;

[0024] (b) Clear the topsoil and weathered matter from the slope and trench to one side of the separated slope, and clear the gneiss rock blocks at the bottom of the trench to the other side of the separated slope, to be backfilled;

[0025] (c) Mix the slope topsoil or foreign soil to be backfilled into the 10cm thick decomposed high-quality organic fertilizer to backfill the trench;

[0026] (d) Use the original hillside with a width of 2m in the middle of the two ditches as the outer field ridge, and trim the field surface to make it a high-outside low-back slope, and maintain a gradient of 3‰ along the contour line in one direction.

[0027] (e) Build ridges with a height of 30 cm on the outer edge of the terraces to retain water and surface runoff, a...

Embodiment 2

[0029] (a) Keep a section of hillside in the original state between two adjacent fields with a width of 2m and a depth of 1.2m, which is called the slope separation, and excavate a trench with a width of 1.5m and a depth of 1m on the slope;

[0030] (b) Clear the topsoil and weathered matter from the slope and trench to one side of the separated slope, and clear the gneiss rock blocks at the bottom of the trench to the other side of the separated slope, to be backfilled;

[0031] (c) Mix the slope topsoil or foreign soil to be backfilled into the 10cm thick decomposed high-quality organic fertilizer to backfill the trench;

[0032] (d) Use the original hillside with a width of 2m in the middle of the two trenches as the outer field ridge, and trim the field surface so that it is in a state of high outside, low and small reverse slope, and maintain a gradient of 5‰ along the contour line in one direction.

[0033] (e) Build ridges with a height of 30 cm on the outer edge of the...

Embodiment 3

[0035] (a) Keep a section of hillside in the original state between two adjacent fields with a width of 2m and a depth of 1.1m, which is called a slope separation, and excavate a trench with a width of 1.5m and a depth of 1m;

[0036] (b) Clear the topsoil and weathered matter from the slope and trench to one side of the separated slope, and clear the gneiss rock blocks at the bottom of the trench to the other side of the separated slope, to be backfilled;

[0037] (c) Mix the slope topsoil or foreign soil to be backfilled into the 10cm thick decomposed high-quality organic fertilizer to backfill the trench;

[0038] (d) Use the original hillside with a width of 2m in the middle of the two trenches as the outer field ridge, and trim the field surface so that it is in a state of high outside and low and small reverse slope, and maintain a gradient of 4‰ along the contour line in one direction.

[0039] (e) Build ridges with a height of 30 cm on the outer edge of the terraces to...

Abstract

The invention discloses a separated slope trench-shaped terrace soil preparation method applied to mountainous regions. A segment of mountain slopes in an original state is reserved between adjacent fields with the width of 2m and soil preparation depth of 1-1.2m, grooves with the width of 1.5m and the depth of 1m are excavated on slope surfaces, and then slope surface soil or local soil is mixed to rotten ripe high quality organic fertilizers with the thickness of 10cm for backfill. A mountain slope original state slope surface with the width of 2m is reserved between two grooves to serve as a ridge. A built field surface is a terrace in a counter-slope state, and the other side of the terrace is high and the inner side of the terrace is low. Another ridge with the height of 30cm is built on the outer edge of the terrace to block and store water and field surface runoff. The whole field surface faces to a direction along a contour line and mains a gradient of 3%.-5% longitudinally. Through using of the method, surface soil and weathered materials on mountainous region surfaces can be centralized and used, the problems of local soil an natural water storage are solved, and thus needs of planting of trees on the mountainous regions are met.

Description

technical field [0001] The present invention relates to a mountain land preparation method, more specifically, relates to a method for land preparation of slope-separated and ditch-shaped terraced fields suitable for mountains Background technique [0002] Slope-separated terraces are to build a horizontal terrace at a certain distance along the original natural slope, and keep a certain width of the original hillside vegetation between the terraces and terraces, so that the runoff from the original slope enters the horizontal field, increasing soil moisture to promote crop growth. Suitable for mountainous areas with insufficient labor force. The terraced fields can be planted with field crops, fruit trees, grass and green manure. [0003] The total area of ​​gneiss mountain land in Taihang Mountains is 1.187 million hectares, of which 120,000 hectares (1.8 million mu) of cultivated land, 133,000 hectares (2 million mu) of forest land, 9,000 hectares (135,000 mu) of garden ...
