(7) An ecological restoration process for a mining area. After the acanthus pungens grow normally, the ecological restoration engineering of the relevant mining area can be developed, and the ecological restoration engineering can be basically divided into 3 types:
A. gentle bare mine areas. The general mining area still has a soil layer, but is mostly an exposed area, and is seriously polluted by different types of soil and water loss is serious. In the area of the backward mountain of the environmental protection engineering academy of Guangdong, the gentle bare mine area environment is simulated, and the environment is about every 1-2 m21 plant is planted, the depth of a planting groove is 20-30 cm, the width of the planting groove is 30-40 cm, a base fertilizer formed by mixing dry chicken manure and plant ash is paved at the bottom in a volume ratio of 1:1, and the thickness of the base fertilizer is about 3 cm. Transplanting the acanthus spinosus linn matrix in the plastic flowerpot to a planting groove, and filling the planting groove with local soil. And slightly compacting after water is poured. Then local soil is paved to form a small hill shape. The water supply is guaranteed according to seasons, temperature and weather 1 month before planting. After the growth, the bur vine grows rapidly, and meanwhile, the seed is a wood vine, a composite greening layer with a certain thickness can be formed rapidly, and the water and soil loss is effectively controlled.
B. Exposed side slopes (below 45 degrees) of the mine. The exposed slope area generally has a thin soil layer, more rock blocks and heavier water and soil loss. In the slope region of the famous abandoned mine in the south sea area of the Foshan city, planting grooves with different lengths are dug at intervals of 4-5m according to the actual situation, and the depth is about 40 cm. The downhill part of the planting groove with a steep part can use oblique upward wood, cement blocks and the like as a support, and steel nails are driven under the support, wherein the depth of the steel nails is 20-30 cm. And paving a base fertilizer mixed by dry chicken manure and plant ash with a bedding volume ratio of 1:1 in the planting groove according to the actual depth. Transplanting the acanthus spinosus linn matrix in the plastic flowerpot to a planting groove, and filling the planting groove with local soil. And slightly compacting after water is poured. The water supply is guaranteed according to seasons, temperature and weather 1 month before planting, and a water spraying vehicle can be used for remotely supplementing water.
C. The bare steep slope of the mine and the rock wall area (more than 45 degrees). The abrupt slope is generally a rock, less soil layers are formed, water and soil loss is heavy, and the pivot points on which the vine can climb are few. The rock wall area is difficult for ecological restoration and almost has no soil layer. In the side slope area of the unknown abandoned mine in the south sea area of the Foshan city, the specific ecological restoration engineering is divided into three major steps.
a. And a climbing net structure is erected between the steep slope area and the rock wall area. Paving a thin steel cable from top to bottom every 2-3 m; and fixing the steel nails by using the steel nails every 1-2 m high. The transverse fixing is carried out by using a thinner steel rope to form a net structure together.
b. A cultivation area. In the soil area close to the steep slope and the bottom of the rock wall, the soil in the area is primarily improved, and the soil is loosened by using a small excavator, and the soil can be excavated to about 5000m in one day2And pouring the culture mixed substrate into the mixture. And digging out a planting groove with the depth of 30-40 cm after leveling. Paving a base fertilizer prepared by mixing dry chicken manure and plant ash in a bedding volume ratio of 1: 1. Transplanting the acanthus spinosus linn matrix in the plastic flowerpot to a planting groove, wherein the density is 1-1.5 m per plant, and filling the planting groove with a mixed culture matrix. Pouring water, and filling the mixed matrix into a small hill. And planting in planting grooves at the positions 2-3 m away from the edges at the tops of the steep slopes and the rock walls, so that the planting grooves can be planted upwards and downwards at the same time. Combining the hybrid acanthus pungens with the vine such as the big flower crow (Thunbergia grandiflora) in the proportion of acanthus pungens: big flower crow mouth: all-grass of littleleaf climbing fern is 3:1: 1.
c. Management techniques. In the management, because the acanthus pungens have obvious climbing habit, and can form firm wooden liana structural layer, have fine steadiness. The vine structural layer is reinforced, the wooden vine can be tied to the climbing net by using plastic restraint belts in management, fertilizer mainly containing nitrogen fertilizer is reasonably applied, and the vine structural layer is trimmed and tied together to form an upward climbing trend. In the actual planting, no obvious plant diseases and insect pests are seen, the stress resistance is strong, the growth speed is high, and a covering layer can be well formed under normal management and protection.
(8) And (4) overall effect. By 6 months in 2017, the spiny vines planted in unknown abandoned mines in the southern sea areas of Guangdong environmental protection engineering academy of industry and the Fushan City have good growth vigor and no obvious plant diseases and insect pests, and very good vegetation cover layers are formed in gentle areas and gentle slope areas, so that the excellent greening and ecological restoration effects are achieved. The steep slope area also begins to climb up the climbing net and form a covered vegetation layer at the bottom. The roxburgh anoectochilus terminal bud, the tulip hyacinths and the small-leaf climbing fern sand at the tops of the steep slopes are good in growth, wherein the tulip hyacinths are partially suspended below the steep slopes to form a certain ecological restoration landscape. The overall engineering evaluation is high (see FIGS. 1-2).
