Problems solved by technology

However, due to the steepness and high height of the field ridges, it is difficult to use them, and the gravity erosion caused by them is the main reason for the collapse of field ridges and the destruction of terraced fields.

Embodiment Construction

[0013] Attached below figure 1 The present invention is described in further detail with specific implementation process:

[0014] The slope land preparation and afforestation method of the present invention, at first, push out wide strip terraced field 1 on slope with bulldozer, when the height of terraced field exceeds 3m, build narrow strip terraced field 2, and according to the situation of slope slope, step by step according to terraced field height 2-3m Wide terraces 1 or narrow terraces 2 are built according to the standard, thus forming one wide terrace 1 and one narrow terrace 2, or a mixed terrace between one wide terrace 1 and multiple narrow terraces 2, wherein the narrow terraces The width of 2 is 3-4m, meanwhile, the field surface of wide terraced field 1 or narrow terraced field 2 kept inclining 3-5° inwardly; then, build high side 3 on the outer edge of terraced field, and artificially tamp to form 50×50cm Finally, economic tree species are planted in the terr...

Abstract

The invention discloses a wide and narrow terrace field mixture slope surface soil preparation and forestation method. The method induces the step of building a wide-strip terrace field by bulldozing a hillside field through a bulldozer, building a narrow-strip terrace field when the height of the wide-strip terrace field is larger than 2-3m, sequentially building a wide-strip terrace field or a narrow-strip terrace field with the height criterion of 2-3m, then building high ridges at the outer edges of the terrace fields to form 50*50cm water-retaining ridges through manual punning, and at last, planting economic trees or crops in the terrace fields to complete the process of wide and narrow terrace field mixture slope surface soil preparation and forestation. The method can effectively reduce water and soil loss of hillside orchards and eliminate and reduce ridge collapse caused by gravitational erosion, and further has the advantages of being obvious in improvement effect, strong in practicality, simple and especially suitable for being popularized and used in economic forest construction and agricultural production in earthy mountainous areas with thick soil layers.

Description

technical field [0001] The invention relates to a slope land preparation and afforestation method, in particular to a method for slope land preparation and afforestation and slope protection by using a mixture of wide and narrow terraces, and belongs to the field of engineering afforestation. Background technique [0002] Mountain orchard is one of the main measures for the development of mountainous agricultural economy, and it is also a main channel for the broad masses of farmers to make a fortune. [0003] Affected by slope conditions, early technologies mostly used narrow terraces and narrow terraces separated from slopes and reversed slopes to prevent soil erosion. Tiao terraces mainly rely on manual work, with a low degree of mechanization and low engineering efficiency. Under the impact of urbanization, the insufficient supply of rural labor force directly affects the development and construction of mountain orchards. After the 1990s, in order to effectively prevent...
