Appropriate land consolidation method in hilly and mountainous areas

Abstract

The present invention belongs to the technical field of land, and specifically discloses a method for land improvement in hilly and mountainous areas, including the following steps: slope measurement; land property classification according to the slope, which is divided into horizontal fields, gentle slope fields, steep slope fields and terraces field; gravel cleaning, demolition of field ridges and ditches; construction of passages; field layout, dividing its length and width according to the nature of the field; digging pits and turning soil; fertilization. The purpose of the present invention is to provide a kind of regulation method that can make the land in hilly and mountainous areas adapt to large and medium-sized mechanized planting.

Description

technical field [0001] The invention belongs to the technical field of land, and specifically discloses a method for machine-based improvement of land in hilly and mountainous areas. Background technique [0002] Chongqing is a typical hilly area with complex terrain, high mountains and steep slopes. The city's cultivated land generally has problems such as small plots, steep slopes, scattered, and unsuitable infrastructure. Among the city's 36.576 million mu of cultivated land, hilly land accounts for 98%; sloping cultivated land with a slope of more than 15° accounts for 47.1% of the cultivated land area, and sloping cultivated land with a slope of more than 25° that is not suitable for cultivation accounts for 14.7% of the cultivated land area; a single piece of cultivated land More than 80% have an area of ​​less than 1 mu, the per capita cultivated land area is 1.12 mu, 60% have cultivated land scattered in more than 3 places per household, and the average cultivated l...

Problems solved by technology

Among the city's 36.576 million mu of cultivated land, hilly land accounts for 98%; sloping cultivated land with a slope of more than 15° accounts for 47.1% of the cultivated land area, and sloping cultivated land with a slope of more than 25° that is not suitable for cultivation accounts for 14.7% of the cultivated land area; a single piece of cultivated land More than 80% have an area of ​​less than 1 mu, the per capita cultivated land area is 1.12 mu, 60% have cultivated land scattered in more than 3 places per household, and the average cultivated land scale of each household is less than 5 mu; Difficult access to local agricultural machinery

However, the use of small equipment such as micro-tillers has low efficiency, low output, and extremely labor-intensive labor, and the benefits are very limited.

In order to solve this problem, Japan and other places have proposed land rectification methods to adapt the land to modern large-scale machinery and equipment. However, because the land terrain is very different, it cannot be directly used for reference. New rectification methods need to be proposed for the hilly and mountainous terrain. method
