Embodiment 1

[0020] Slope farmland improvement method, the improvement method includes the following steps:

[0021] (1) First push the mellow soil on the ground to one side, smooth and compact the subsoil of the sloping ground by machinery, and treat the sloping ground into a terraced shape with the same compactness;

[0022] (2) Adjust the height difference between adjacent ridges according to the size of the slope of the slope;

[0023] Among them, the height difference between adjacent ridges is 60cm;

[0024] (3) Backfill 20cm of the mellow soil in step (1) on the compacted subsoil.

Embodiment 2

[0026] Slope farmland improvement method, the improvement method includes the following steps:

[0027] (1) First push the mellow soil on the ground to one side, smooth and compact the subsoil of the sloping ground by machinery, and treat the sloping ground into a terraced shape with the same compactness;

[0028] (2) Adjust the height difference between adjacent ridges according to the size of the slope of the slope;

[0029] Among them, the height difference between adjacent terraces is 80cm;

[0030] (3) Backfill 40cm of the mellow soil in step (1) on the compacted subsoil.

Embodiment 3

[0032] Slope farmland improvement method, the improvement method includes the following steps:

[0033] (1) First push the mellow soil on the ground to one side, smooth and compact the subsoil of the sloping ground by machinery, and treat the sloping ground into a terraced shape with the same compactness;

[0034] (2) Adjust the height difference between adjacent ridges according to the size of the slope of the slope;

[0035] Among them, the height difference between adjacent ridges is 100cm;

[0036] (3) Backfill 30cm of mellow soil in step (1) on the compacted subsoil.

Abstract

The invention relates to the technical field of slope farmland improvement, in particular to an improvement method for slope farmland. The improvement method comprises the steps that firstly, mellow soil on the ground is pushed to one side, and slope land undersoil is mechanically treated to be smooth and compact, wherein the compactness needs to be consistent, and the slope land is treated into aterrace shape; secondly, according to the gradient of the slope land, the height difference between every adjacent ridges is adjusted to be 60-100 cm, and the compact undersoil is backfilled with mellow soil with the thickness of 20-40 cm. The improvement method for the slope farmland can effectively overcome the defects of large time consumption and poor improvement effect of existing improvement methods for slope farmland.

Description

Technical field [0001] The invention relates to the technical field of slope farmland improvement, in particular to a method for slope farmland improvement. Background technique [0002] Sloping farmland refers to dry land distributed on hillsides with poor ground flatness, serious loss of water, soil, and fertilizer, and low crop yields. The concept of the main feature "slope land" generally refers to the landform type between 6 and 25° (mostly called slope farmland after reclamation). The existence of sloping farmland seriously restricts the substantial increase in dryland crop yields. Nowadays, when improving slope land in many places, bulldozers are used directly. Raw soil and mature soil are mixed together. In this way, the treated land needs to be processed for 1-2 years before planting, and a large amount of agricultural fertilizer is required; After the land is transformed in the same year, crops can be produced in the same year, reducing excessive agricultural fertiliz...
