Problems solved by technology

When the wind blows, the topsoil, seeds, dead grass, and fallen leaves on the slope are blown away by the wind, which also causes seed and soil erosion. The sand and stone on the slope are exposed, and the plant growth is uneven and the coverage rate is low.

Embodiment Construction

[0010] Such as figure 1 , figure 2 As shown, the surface soil stripped from the open-pit mine was selected, and 80% of the soil and 20% of the fermented cow and sheep manure were prepared to make nutrient soil. The planting baskets made of plant branches were placed in a seedling cultivation ditch with a width of 50 cm and a depth of 50 cm. , the upper diameter of the planting basket is 35cm, the bottom diameter is 30cm, the height is 35cm, and the gap between the plant branches is 1cm. The bottom of the planting basket is filled with 15cm thick nutrient soil, and the saplings are planted in the basket. The distance between the planting baskets is 50cm, and the gap in the middle is tightly covered with surface soil. Water once within 24 hours, and then water 4-6 times in the first year. Water 3-4 times in the second year. Apricot, seabuckthorn, caragana, medlar and strange willow are cultivated for 3-6 months; elm, poplar and willow are cultivated for 6-12 months; spruce an...

Abstract

The invention discloses a slope forest planting method which is mainly used for reclaimation tree-planting on the slope of a waste disposal site of an open pit in arid regions. The method mainly comprises the following steps of: selecting surface soil peeled from the open pit and nutritional soil prepared from sheep and cow dung, putting the nutritional soil in a planting basket weaved by plant wickers, planting seedlings in and putting in a seedling cultivating ditch, then irrigating, transplanting into a slope planting cave together with the planting basket after various seedlings are watered and irrigated for 3 to 18 months, filling by surface soil, well trimming the seedlings, and preserving a water hole at the periphery, wherein the seedling survival ratio after three-year watering can reach more than 88 percent. The planting basket is weaved by plant wickers, which can become fertilizer after rotting and has no pollution to environment. The root system of a tree after growing upcan stabilize the soil, protect the slope and prevent soil erosion and water loss; branches and leaves at the crown can reduce the wind speed and runoff amount, prevent rain water from directly scouring the slope and protect the slope, therefore, the ecological environment of a plurality of tree and grass vegetation is formed.

Description

technical field [0001] The invention relates to a method for reclamation and afforestation, in particular to a method for reclamation and afforestation on slopes of open-pit mine dumps in arid areas. Background technique [0002] At present, known open-pit mine dump slope protection reclamation, greening and afforestation adopts the method of inserting branches into grids and setting up grids with grass to sow seeds. Due to the large space area of ​​the branch grid and the grass grid, the strong wind force on the high slope, and the serious loss of seeds and topsoil, the rainwater directly falls on the slope during rainfall or artificial irrigation. The grid cannot block the rainwater to generate runoff, and landslides are prone to occur and mudslides. When the wind blows, the topsoil, seeds, dead grass, and fallen leaves on the slope are blown away by the wind, which also causes seed and soil erosion. The sand and stone on the slope are exposed, and the plant growth is une...
