Windproof and sand-fixing greening and planting method on barren land

Abstract

The invention discloses a greening and planting method for wind prevention and sand fixation on a barren ground surface. The greening and planting method comprises the following steps: preparing a premix; preparing conical cultivation basins from the premix; preparing gauzes, and uniformly extending yarns from the gauzes at intervals; preparing conical water bags; extending the yarns into the conical cultivation basins; filling the conical cultivation basins with the conical water bags, and impacting the yarns; filling the conical cultivation basins with cultivation soil, and then, sealing openings of the conical cultivation basins by using a pug; drying the conical cultivation basins fixedly arranged on the gauzes; unfolding and spreading the gauzes fixedly provided with the conical cultivation basins on the barren ground surface by column; after 3-4 months, uniformly spreading cultivation soil on the gauzes; and digging planting holes among the gauzes arranged by column, and implanting drought-resistant shrubs. By using the greening and planting method, vegetations with relatively high cover degrees can be formed on a target ground surface within one growing reason, so that a satisfied vegetation cover effect is achieved; in addition, the survival rate of the shrubs is high, the forest establishment time is short, and the forest establishment effect is good.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a windbreak and sand-fixing greening and planting method for barren land. Background technique [0002] At present, how to prevent the land from being desertified generally adopts the method of planting shelter forests, that is, planting drought-resistant turf, shrubs, trees, etc. in the mobile sand dune area. However, the existing way of building a shelterbelt takes a long time to form a shelterbelt. The main reasons are: first, the plants of shrubs and trees are low in seedling stage, and the gap between plants is large. Second, the sandy soil in the mobile sand dune area is always in a state of flow, and it is easy to blow down or bury the planted shrubs and tree seedlings, which makes the survival rate of the shrubs and trees low. It usually takes more than ten years to form a shelterbelt that can prevent wind and sand fixation. Therefore, the existing windbreak and...

[0002] At present, how to prevent the land from being desertified generally adopts the method of planting shelter forests, that is, planting drought-resistant turf, shrubs, trees, etc. in the mobile sand dune area. However, the existing way of building a shelterbelt takes a long time to form a shelterbelt. The main reasons are: first, the plants of shrubs and trees are low in seedling stage, and the gap between plants is large. Second, the sandy soil in the mobile sand dune area is always in a state of flow, and it is easy to blow down or bury the planted shrubs and tree seedlings, which makes the survival rate of the shrubs and trees low. It usually takes more than ten years to form a shelter forest that can prevent wind and sand fixation. Therefore, the existing windbreak and sand fixation greening planting technology takes a long time to form a shelter forest, which cannot effectively prevent land from being desertified, and the effect of sand control is poor.
