Description

Technical Field

[0001] This utility model relates to the field of low-efficiency forest transformation technology, specifically, to a low-efficiency forest transformation structure. Background Technology

[0002] Forests are a precious resource in my country, playing an indispensable role in maintaining ecosystem stability and improving the ecological environment. With my country's increasing emphasis on forest resources, improving forest quality and promoting the sustainable use of resources have become hot topics. However, the ecological, economic, and social benefits generated by low-efficiency forests cannot meet current needs. Artificial transformation of low-efficiency forests aims to create multi-layered, uneven-aged, and seed-grown mixed forests, thereby enhancing forest productivity, improving stand structure, increasing stand quality, and fully realizing the ecological, economic, and social benefits of forest stands.

[0003] Therefore, it is urgent to improve forest productivity through scientific transformation of low-efficiency forests in order to ensure the sustainable use of forest resources. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a low-efficiency forest transformation structure that, through reasonable planting and water storage structure, makes full use of soil, sunlight, rainwater and fallen leaves to increase tree growth, increase forest stock, protect forest biodiversity, conserve soil and water resources, promote carbon sequestration and maintain ecosystem stability.

[0005] This utility model provides a structure for transforming inefficient forests, including horizontal steps and slope steps, wherein:

[0006] At least one horizontal ditch is provided on the horizontal step, which divides the horizontal step into several tree planting areas. Several planting pits are provided in the tree planting areas, and trees are planted in the planting pits. Arc-shaped pits are provided around the planting pits, and a set of water storage pits and a set of infiltration holes are provided around the arc-shaped pits. Water retaining walls are provided at the edges of the horizontal step. The horizontal step is connected to the planting pits through a water supply pipe, and the water supply pipe is inclined downward towards the planting pit. The bottom of the water storage pit is connected to the infiltration holes through a seepage pipe, and the seepage pipe is inclined downward towards the infiltration hole.

[0007] The slope terraces are shrub planting areas, and there are several fish-scale pits in the shrub planting areas, where shrubs are planted.

[0008] Preferably, the arc-shaped pit is provided with a manure layer and a humus layer from bottom to top.

[0009] Preferably, the infiltration hole is provided with a layer of dead branches, and the top of the infiltration hole is provided with a sealing layer.

[0010] Preferably, the depth of the arc-shaped pit is 40cm.

[0011] Preferably, the water storage pit has a depth of 30cm, a width of 30cm, and a length of 60m.

[0012] Preferably, the infiltration hole is located 100cm from the base of the tree root, with a depth of 40-80cm and a diameter of 9-15cm.

[0013] Preferably, the width of the retaining wall is 30cm and the height is 20cm.

[0014] The working principle of this utility model is as follows: This utility model's low-efficiency forest transformation structure employs a mixed planting method, planting both arbor species (such as apricot and spruce) and shrub species (such as peach and lilac), with a row spacing of 4-6 meters and a plant spacing of 3-5 meters. Specifically, shrubs are planted on slope terraces using a fish-scale pit planting method, while on horizontal terraces, rainwater is collected through horizontal ditches. Planting pits with a depth of 50 cm and a diameter of 50 cm are excavated to plant arbor species, promoting tree survival. Simultaneously, a 30 cm wide and 20 cm high retaining wall is constructed at the edge of the horizontal terraces. Finally, the horizontal ditches are 1 meter wide. Under the existing terrain conditions of the horizontal terraces, these ditches are narrowed on-site, saving afforestation costs while effectively collecting rainwater. Secondly, a deep burial method using litter is adopted. A 40cm deep arc-shaped pit is dug near the root system, and a layer of manure is filled into the pit. The litter near the sample trees is then buried deep into the soil to form a humus layer, increasing nutrients around the deeper soil layers and improving the soil's physical structure. As the litter gradually decomposes, the deep soil structure improves, increasing soil nutrients and promoting tree growth. This measure has a long-lasting effect. Additionally, rainwater harvesting is used to increase soil moisture around the tree roots. A 30cm deep, 30cm wide, and 60m long water storage pit is dug near the roots. About 100cm from the base of the tree roots, two infiltration holes, 40-80cm deep and 9-15cm in diameter, are drilled on the lower-lying areas on both sides of the tree. Rainwater is collected in the water storage pit and then replenished to the tree roots through the infiltration holes, improving rainwater utilization efficiency and promoting tree growth. This method collects rainwater, allowing it to directly replenish the deeper soil layers and reducing ineffective evaporation from the surface soil. For branches at the base of the main trunk that affect thickening and height growth, as well as weak or withered branches, artificial tending can be carried out using pruning shears and saws. The artificially tended branches are cut into sections of a certain length and placed into the infiltration holes on both sides of the trees to form a layer of dead branches. As the dead branches and fallen leaves decompose, nutrients in the deeper soil layers can be directly increased. At the same time, the dead branch layer directly blocks the infiltration holes, reducing ineffective evaporation from the soil within the infiltration holes. Forest waste can also be directly converted on-site.

[0015] The beneficial effects of this utility model are as follows: This utility model's low-efficiency forest transformation structure fully utilizes soil and sunlight through reasonable planting on horizontal and slope terraces. Furthermore, the installation of horizontal ditches and fish-scale pits for water storage effectively collects rainwater, improving the utilization rate of mountain rainwater. Additionally, the design of water storage pits and infiltration holes promotes rainwater penetration into tree roots, fostering plant growth. An arc-shaped retaining wall is also installed to deeply bury litter near the sample trees in the soil. As the litter gradually decomposes, the deep soil structure is improved, soil nutrients increase, and thus forest growth is promoted. Therefore, this structure can fully utilize soil, sunlight, rainwater, and fallen leaves, increasing forest growth, increasing forest stock, protecting forest biodiversity, conserving water and soil, promoting carbon sequestration, and maintaining ecosystem stability.
