Problems solved by technology

The slope of the terrace wall is one of the most exposed areas in the regional economic orchard. In addition, the newly built terraced fields are sparsely covered with vegetation and the surface is exposed. If no measures are taken, it will cause serious soil loss.
However, due to site conditions and economic constraints, it is difficult to restore vegetation on terrace walls in some areas, which intensifies water erosion on terrace walls and slopes, and increases the activity of gravity erosion

Embodiment 1

[0044] The present embodiment provides a kind of terraced field soil fixing method, comprising:

[0045] In April of that year, paspalum broadleaf was planted on the ridge of terraced fields. The dosage of seeds is 2.5g / m 2 , and the rest are planted and cultivated according to the specific operations in the above step S2.

[0046] The biological seed coat inoculation was carried out 3 months after planting Paspalum broadleaf. The specific operation of biological seed coat inoculation is as follows:

[0047] Collect well-grown biological crusts in the field, use a small shovel to carefully scoop out the surface layer of 10-20mm thick biological crusts, dry the collected samples in the shade indoors, and then separate them from impurities and soil, and use a plant grinder to crush them , Select a piece of bare land near the terraced fields, take the soil in the 0-10cm soil layer, air-dry it indoors and pass it through a 1mm sieve to obtain fine soil. Take NPK mixed fertiliz...

Embodiment 2

[0054] The present embodiment provides a kind of terraced field soil fixing method, comprising:

[0055] In April of that year, paspalum broadleaf was planted on the ridge of terraced fields. The dosage of seeds is 2.7g / m 2 , and the rest are planted and cultivated according to the specific operations in the above step S2.

[0056] The biological seed coat inoculation was carried out 3 months after planting Paspalum broadleaf. The specific operation of biological seed coat inoculation is as follows:

[0057] Collect well-grown biological crusts in the field, use a small shovel to carefully scoop out the surface layer of 10-20mm thick biological crusts, dry the collected samples in the shade indoors, and then separate them from impurities and soil, and use a plant grinder to crush them , Select a piece of bare land near the terraced fields, take the soil in the 0-10cm soil layer, air-dry it indoors and pass it through a 1mm sieve to obtain fine soil.

Embodiment 3

[0064] The present embodiment provides a kind of terraced field soil fixing method, comprising:

[0065] In May of that year, paspalum broadleaf was planted on the ridge of terraced fields. The dosage of seeds is 2.3g / m 2 , and the rest are planted and cultivated according to the specific operations in the above step S2.

[0066] The biological seed coat inoculation was carried out 3 months after planting Paspalum broadleaf. The specific operation of biological seed coat inoculation is as follows:

[0067] Collect well-grown biological crusts in the field, use a small shovel to carefully scoop out the surface layer of 10-20mm thick biological crusts, dry the collected samples in the shade indoors, and then separate them from impurities and soil, and use a plant grinder to crush them , Select a piece of bare land near the terraced fields, take the soil in the 0-10cm soil layer, air-dry it indoors and pass it through a 1mm sieve to obtain fine soil.

Abstract

The invention relates to the technical field of agriculture and forestry and provides a terrace soil fixing method. The method includes: planting melastoma dodecandrum lour in the surface of a terrace; planting herbal plants with developed root systems on ridges of the terrace; when the herbal plants grow to be grass excellent 30cm in height, inoculating biological crust on the surface of a terrace wall. A terrace ecological slope protection structure is obtained after adopting the method for soil fixing, the terrace after soil fixing through the method is less prone to water and soil loss, and the method is good in protection effect on the terrace wall, the terrace surface and the ridges, suitable for commercial fruit forestry terraces and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry, in particular to a soil fixing method for terraced fields and an ecological slope protection structure for terraced fields. Background technique [0002] At present, the economic fruit forest in the southern hilly area is one of the main measures for the development of regional agricultural economy, and it is also an important channel for the peasants to make a fortune. Among them, the transformation of slope land into narrow terraced fields (reversed slope terraced fields) is one of the main technologies for water and soil conservation in the southern hilly area. . Due to limited site conditions, densely populated areas, and prominent human-land conflicts, the width of terraced fields is much smaller than that in arid and semi-arid areas in China, and in order to increase the width of fields, the outer slopes / step walls of terraced fields are relatively steep. The terraced wall...
