Description
Technical Field
The invention relates to the field of greening, in particular to a planting method of an ecological arbor with an eroded landform.
Background
China is a multi-mountain country, and the mountain area accounts for 2/3 of the territorial area; and is the country with the widest distribution of loess in the world. The topography of hilly and loess areas fluctuates. Loess or loose weathering hulls are highly susceptible to erosion in the absence of vegetation protection. Most areas belong to monsoon climate, the precipitation is concentrated, the precipitation in rainy season is 60% -80% of annual precipitation, and rainstorm is increased. The geological and geomorphic conditions and climatic conditions which are easy to cause water and soil loss are the main reasons for causing water and soil loss in China.
The scientific publishing company 'concise water conservancy and hydropower dictionary' in 1981 proposes that the water and soil loss refers to the phenomenon that the earth surface soil, the matrix and the rock are subjected to external forces such as water power, wind power, gravity, freeze thawing and the like, so that the earth surface soil, the matrix and the rock are subjected to various damage, movement and accumulation processes and the loss of water. This is a generalized loss of water and soil. The narrow definition of water and soil erosion refers to the phenomenon of hydraulic erosion. This is somewhat similar to the soil erosion described above, so the term "water and soil erosion" is often used equally to refer to "soil erosion".
In northern areas of China, the erosion phenomenon is particularly serious, so that the earth surfaces of many mountain areas are gravels and lack of soil. The surface soil of many hilly areas is a broken stone soil layer, the water and soil loss is serious, the water retention is poor, the nutrient is less, and the climate characteristics mainly show that the seedlings are dry and rainy, so that the seedlings lack the water required by growth and die when being planted in the environment.
In the prior art, the condition of water shortage of the nursery stock is relieved only by adding a water-retaining agent or increasing artificial irrigation, and the effect is not ideal. After the seedlings are planted, water on the surface of a planting soil layer is quickly evaporated, and water is accumulated at the bottom of a planting pit to cause the root rot of the seedlings. The problem of the survival rate of the nursery stock in the water and soil loss area can not be solved.

Further, the material for preventing water loss may be bentonite waterproof blanket or HDPE high-density impermeable film.
Furthermore, the thickness of the filter layer is 120-180 mm, and the filter layer is composed of 3 parts of sand and 1 part of gravel.
Furthermore, the water collecting device is formed by arranging and stacking 2-3 discarded plastic baskets of the transportation place and the grass flower to fill the water storage pit, the height of the water collecting device is not more than that of the water storage pit, the root control device which is removed when the nursery stock is transplanted is placed at the top, the root control device and the plastic baskets are fixed by galvanized iron wires, and the funnel-shaped tip of the root control device faces downwards.
Further, a PVC water supply pipe with the pipe diameter of the water storage pipe being 180-220 mm is vertically inserted into the planting soil, 5-10mm capillary holes are formed in the bottom of the water storage pipe, waste medical droppers which are disinfected at high temperature and are pollution-free are inserted, and water is supplied to the root of the nursery stock in a drip irrigation mode; the water storage pipe is exposed out of the surface of the planting soil to prevent water from overflowing; a small hole of 100mm is arranged at the joint of the water storage pipe and the water diversion pipe, so that the water diversion pipe is connected with the water storage pipe.
Furthermore, the exhaust pipe and the water conduit adopt PVC pipes with the pipe diameter of 100 mm.
Compared with the prior art, the invention has the following beneficial effects: according to the planting method, the water storage pit water collecting device and the water-retaining planting layer are arranged, so that water required by plant growth is effectively collected and retained, and the seedling planting survival rate in arid hilly areas is effectively improved. The exhaust pipe which can be manually intervened is buried, so that the phenomenon that roots of plants are accumulated with water and rotten can be effectively prevented in rainy seasons. Has good elasticity when adapting to environmental change, stores and preserves water when raining, and releases and utilizes the stored water when drought. The survival rate of the nursery stock in an erosion landform environment can be well improved.
