Rapid cultivation method of desertified sand land vegetation

Abstract

The invention discloses a rapid cultivation method of desertified sand land vegetation. The method comprises the steps as follows: a premixed material is prepared; conical cultivating pots are prepared from the premixed material; gauze screens are prepared, and yarns are uniformly spaced on the gauze screens and extend from the gauze screens; conical water bags are prepared; the yarns extend into the conical cultivating pots; the conical water bags fill the conical cultivating pots, and the yarns are compressed; the conical cultivating pots are filled with cultivating soil, and then openings of the conical cultivating pots are sealed with pug; the conical cultivating pots fixed on the gauze screens are dried; the gauze screens fixedly provided with the conical cultivating pots are spread in rows on barren earth surface; after 80-110 days, the cultivating soil is uniformly spread on the gauze screens; and planting holes are dug among the gauze screens in rows, and drought-control shrubs are planted in the planting holes. With the adoption of the rapid cultivation method of the desertified sand land vegetation, the vegetation with a higher cover degree can be formed on the target earth surface within one growing season, a satisfied vegetation cover effect is realized, 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 method for rapidly growing vegetation in desertified sandy 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 sandfi...

[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.
