Device for planting arbors in rocky desertification regions and preparation and planting method thereof

Abstract

The invention provides a device for planting arbors in rocky desertification regions and preparation and planting method thereof. The planting device includes a basal disc parent body, an evaporation-proof cover, moisture absorption roots, and a water storage layer; the basal disc parent body is a circular column obtained by compression forming of water retention nutrient soil; the evaporation-proof cover is formed by combining two half circular discs through a buckle, the centre of the evaporation-proof cover is provided with a growth hole, and the bottom of the evaporation-proof cover is provided with a plurality of water collection holes and funnels; each moisture absorption root is cylindrical bar-shaped; the water storage layer is formed by nutrient soil covered by high water absorbing fibers; the basal disc parent body is positioned in a rock hole dug in a rock, the evaporation-proof cover covers an upper part of the basal disc parent body, the water storage layer is positioned on the bottom of the basal disc parent body, and a plurality of the moisture absorption roots are positioned on the bottom of the water storage layer and contact the water storage layer. According to the invention, the beneficial technical effects are that the good moisture and nutrient substances are provided for early survival and growth of tree seedlings, so that the tree seedlings can take root and survive easily, and the roots of the trees can grow downward along the moisture absorption roots; and the structure is simple, and the operation is convenient.

Description

field of invention [0001] The invention relates to arbor planting technology in a rocky desertification area, in particular to an arbor planting device and a preparation and planting method in a rocky desertification area. Background technique [0002] Rocky desertification refers to the continuous degradation and loss of vegetation due to human disturbance under the tropical and subtropical humid and semi-humid climate conditions and the natural background of karst development, resulting in the loss of water and soil resources, the decline of land productivity, and the large area of ​​bedrock exposed to the body. The surface presents a land degradation process similar to a desert landscape. For a long time, the natural vegetation in the rocky desertification area has been continuously destroyed, and a large area of ​​steep slopes has been reclaimed, resulting in the exposed surface. In addition, the soil layer in the karst rocky mountainous area is thin, the bedrock is expo...
