Method for afforestation seeding under condition of difficult land cultivating

Abstract

The invention discloses a method for afforestation seeding under the condition of difficult land cultivating. The method comprises the following steps: firstly, selecting drought-enduring and infertile-resisting plant seeds, then mixing loess soil and an organic fertilizer to prepare nutrient soil, subsequently, disinfecting, soaking and drying the plant seeds in shade and then mixing the plant seeds with the nutrient soil, covering a layer of nutrient soil on the surface of the plant seed to prepare a seed nutrition cover, conducting land preparation and excavation on barren mountains and slopping fields with gangues and mineral waste residues at intervals, mixing the seed nutrition cover and a water retaining agent and the planting the mixture in a hole, and covering soil on the hole. In the invention, as the plant seed is drought-enduring and infertile-resisting, and the water retaining agent can absorb a large amount of water in rainy days, release water slowly in sunny days, and can sufficiently guarantee the water needed by sprouting of the plant seeds and the growth of seedlings, so that the plant seeds can obtain enough water and nutrition, the seed sprouting rate is improved, and the seedling survival rate is improved. According to the method for afforestation seeding, the operation is simple, the afforestation cost is low, the survival rate is high, and the average survival rate is more than 83.3%.

Description

technical field [0001] The invention relates to a method for afforestation on barren hills and slopes under difficult conditions caused by mining, natural disasters and the like. Background technique [0002] Due to human activities such as mining and quarrying and natural disasters such as mudslides, the forest land was destroyed, resulting in a large amount of gangue and slag directly piled up in the mining area, forming a large area of ​​barren hills and slopes. If these barren hills and slopes are not comprehensively treated in a timely manner, the balance of water and soil will be damaged, leading to serious erosion of soil and water, and will have a bad impact on the environment. At present, no effective method has been found for greening treatment under these difficult conditions. In view of the increasingly prominent problems of environmental pollution and ecological damage caused by mining, a large number of abandoned mines need comprehensive greening and restoratio...

Problems solved by technology

If these barren hills and slopes are not comprehensively treated in a timely manner, the balance of water and soil will be damaged, leading to serious erosion of soil and water, and will have a bad impact on the environment. At present, no effective method has been found for greening treatment under these difficult conditions.

In view of the increasingly prominent problems of environmental pollution and ecological damage caused by mining, a large number of abandoned mines need comprehensive greening and restoration of forest ecosystems, and there is no systematic research on how to restore mine vegetation in a short period of time and at low cost

In the patent search of the National Patent Office, patent CN101543178A announced a sandy land environment-friendly drought-resistant afforestation method, which uses planting pits covered with degradable plastic film, nutrient solution drip irrigation, crop straw water retention and other measures to improve the survival rate of afforestation; patent CN1615683A published Saline-alkali land afforestation method, this patent improves the survival rate of afforestation through soil improvement, soil afforestation, large seedling afforestation, deep pit shallow burial, high water pressure salt, etc. Although these two patents have practical value, they are costly and in The survival rate of planting afforestation on barren hills and slopes where a large amount of gangue and slag are accumulated is very low
