Drought resisting and forest planting method for karst region difficult site

Abstract

The invention discloses a drought resisting and forest planting method for a karst region difficult site and relates to the technical field of drought resisting and forest planting. The drought resisting and forest planting method includes the following steps that (1), places for planting trees are selected; (2), the specification and method of soil preparation are performed; (3), a water collection hopper is constructed; (4), rooting water: after nursery stocks are planted, the rooting water is watered sufficiently; (5), forest planting tree species and the age of the nursery stocks: the forest planting tree species comprise cipressus duclouxiana, weeping cypresses, privet, black locusts, nuts, roxburgh rose, peppers, amur honeysuckle and others, and the age of the nursery stocks is one year. The method is simple, easy to operate, low in cost and free of soil pollution and rapidly brought into effect, and has very important and profound significance for accelerating vegetation recovery and vegetation reconstruction in a karst stony desertification environment and for improving the ecological environment. The method is easy and practical to operate, low in cost and high in pertinence, not only does not damage the environment, but also does not affect normal growth of the trees, and is particularly suitable for being popularized and used for forest planting in the difficult site region of the karst stony desertification environment.

Description

Technical field: [0001] The invention relates to a drought-resistant afforestation method on a difficult site in a karst area, and belongs to the technical field of drought-resistant afforestation. Background technique: [0002] Southwest my country's karst region is located in the center of East Asia, one of the world's three largest contiguous karst development regions, with an area of ​​about 540,000 km 2 . At present, more than 100 million people and 48 ethnic minorities live in it. The poor population is relatively concentrated, and the contradiction between people and land is very prominent. Once the slope vegetation is destroyed, the soil erosion will intensify, resulting in the loss of all thin soil layers, resulting in serious rocky desertification. Nutrient regulation and storage capacity decreased rapidly. Rocky desertification has become a major ecological problem that restricts regional economic and social development in Southwest my country's karst region, an...

Problems solved by technology

However, the abnormal water-scarce surface environment in the karst area and the frequent occurrence of extreme drought in the southwest have seriously affected the afforestation in this area, resulting in a greatly reduced effect of rocky desertification control and a lack of sustainability.

For severe rocky desertification areas with severe soil degradation, exposed bedrock, very difficult site conditions, and extreme water shortage, conventional afforestation techniques are difficult to carry out vegetation restoration in this area. It is urgent to develop a drought-resistant plant suitable for difficult sites in karst areas. Afforestation method
