Embodiment 1

[0034] Growing dry elms on rocky barren hills:

[0035] Step 1: Diamond drilling: use a percussion drill to drill a hole 1m deep on the rock in the selected area;

[0036] Step 2: Partial blasting: place 400g of explosives at a distance of 0.9m for blasting; this process will not only form a tree pit, but also cause moderate cracks in the rock, which is conducive to the root growth of transplanted elm seedlings;

[0037] Step 3: Knocking stones and planing pits: Since the diameter at breast height of the transplanted elm seedlings is less than 5cm, according to the diameter of the transplanted elm trees, manually plan the blasted stone pits into a rule of 0.6m in diameter and 0.6m in depth standard circular tree pit;

[0038] Step 4: Move the soil to support: transplant the dry elm on the southern slope of Daqing Mountain in Baotou City, and prepare the nutrient mixture according to its growth needs and the current situation that the Daqingshan rock layer is exposed and the s...

Embodiment 2

[0045] Planting arborvitae on rocky barren hills:

[0046] Step 1: Diamond drilling: use a percussion drill to drill a 1.5m deep hole on the rock in the selected area;

[0047] Step 2: Partial blasting: put 800g of explosives into 1.2m for blasting; this process not only forms a tree pit, but also creates moderate cracks in the rock, which is conducive to the root growth of the transplanted arborvitae seedlings;

[0048] Step 3: Knocking stones and planing pits: Since the diameter of the transplanted Arborvitae seedlings is 5cm

[0049] Step 4: Move the soil to support: transplant the dry elm on the southern slope of Daqing Mountain in Baotou City, and prepare the nutrient mixture according to its growth needs and the current situation that the Daqingshan rock layer is exposed and the soil thi...

Embodiment 3

[0056] To grow almonds on stony hills:

[0057] Step 1: Diamond drilling: use a percussion drill to drill a hole 1m deep on the rock in the selected area;

[0058] Step 2: Partial blasting: put 400g of explosives into the 0.9m place for blasting; this process will not only form a tree pit, but also make moderate cracks in the rock, which is conducive to the root growth of the transplanted almond tree seedlings;

[0059] Step 3: Knocking stone pits: Since the diameter at breast height of the transplanted almond seedlings is less than 5cm, according to the diameter of the transplanted almonds, manually plan the blasted stone pits into a rule with a diameter of 0.6m and a depth of 0.6m. standard circular tree pit;

[0060] Step 4: Move the soil to support: Transplant the dry elm on the southern slope of Daqing Mountain in Baotou City. According to its growth needs and the current situation that the Daqing Mountain rock layer is exposed and the thickness of the soil layer is less...

Abstract

The invention provides a rocky hill afforestation method, comprising the steps of digging tree holes in a rocky barren hill land, filling the tree holes with soil and water required by plantlets to grow, transplanting plantlets to the tree holes, and managing the transplanted plantlets. By using the rocky barren hill afforestation method, survival rate of the transplanted plantlets can be effectively increased and may be increased to 95%.

Description

technical field [0001] The invention relates to the technical field of forestry afforestation, in particular to a method for afforestation of rocky barren hills. Background technique [0002] Rocky barren hills refer to barren hills where limestone, andesite, hornporphyry, etc. are developed, and the site conditions are poor, the soil layer thickness is 5-20 cm, and the soil is barren. Poor, forming small old trees. [0003] Rocky barren hills, because of their thin soil layer, poor soil, and lack of water resources, make the survival rate of transplanted tree species low, which has become the main factor affecting the ecological construction effect of barren hills. There is no effective solution to the problem of ecological afforestation in rocky barren hills and thin soil areas. [0004] Due to poor site conditions, difficult afforestation and high investment costs, rocky barren hills have been regarded as unsuitable forest land for a long time and have not been included...
