Plants growing in this kind of habitat only use a small part of the rainwater stored in the bottom seal or transverse fissure to survive, and there are very few plants that can adapt to the water environment characteristics of this kind of habitat. greatly reduced abundance

Embodiment 1

[0041] This embodiment provides a method for afforesting stone habitats in southwest karst areas, the method comprising the steps of:

[0042] Randomly select a stone habitat in the southwest karst area to be afforested.

[0043] 1) Soak the seeds of the red-backed mountain hemp stalk at room temperature of 26°C for 5 hours, take out the seeds, and use 50g / m 2 Sow the seeds on the well-arranged seedbed at a certain density, cover the soil with 1cm after sowing, cultivate at room temperature, and keep the soil moist; when the seedling height of the red-backed mountain hemp stalk is 8-10cm, transplant it into the nutrient bowl to continue the cultivation, and the nutrients in the nutrient bowl are for the guests. 3kg of soil, 1.5kg of peat soil and 0.5kg of decomposed organic fertilizer;

[0044] 2) in step 1) in the nutrition pot, the seedling height is 60-80cm red-backed mountain hemp stalk, the loropetalum 40-60cm seedling height, the round-leaf Chinese tallow tree with the ...

Abstract

The invention provides a greening method for a southwest Karst region rocky habitat. The method comprises the following steps: planting Alchornea trewioides, plants in a secondary forest, Bermuda grass and Miscanthus floridulus in the southwest Karst region rocky habitat, wherein the plants in the secondary forest are preferably selected from Loropetalum chinense, Sapium rotundifolium and Radermachera sinica. The method is capable of, through introducing three types of grass, shrub and arbor plants, greening the rocky mountain, effectively improving the greening rate, accelerating and promoting the forward succession of the habitat, and bringing the economic benefit to local residents.

Description

technical field [0001] The invention relates to the field of ecological and environmental protection science and technology, and more specifically relates to a greening method for rocky habitats in southwest karst areas. Background technique [0002] The karst area in Southwest China (about 550,000 km 2 ) is the area with the largest karst area, the widest distribution and the most types in the world. The southwest karst area is located in the middle and upper reaches of the Pearl River, and its rocky desertification problem will directly affect the ecological security of the Pearl River Basin, and the key to rocky desertification control is the restoration and reconstruction of vegetation. The intensification of rocky desertification leads to almost complete loss of soil and extreme degradation of vegetation, which eventually leads to the exposure of bedrock and the formation of stony habitats. This kind of habitat basically has no visible soil cover, and its underlying s...
