Embodiment 1

[0015] (1) Soil preparation: Aiming at the characteristics of shallow soil, low fertility, and low water storage function in rocky desertification areas, A. rostralis was selected as the species for vegetation restoration on rocky surfaces. First remove the weeds, and then prepare the ground in a hole shape, with a size of about 15cm×15cm×20cm. The surrounding shrub vegetation was not damaged during site preparation, and the forest and grass vegetation around the planting hole was protected as much as possible, forming a belt-like distribution with the original shrub vegetation;

[0016] (2) Sowing: choose mature, plump seeds, adopt the mode of on-demand sowing, one hole and one grain, cover with original soil after sowing, and do not fertilize when sowing;

[0017] (3) Moisture management: Water enough water when sowing, supplement the soil moisture according to the weather conditions one week after sowing, and perform water management according to the water content of the so...

Embodiment 2

[0020] (1) Soil preparation: From February to May, after clearing weeds, use hole-like soil preparation with a size of about 15cm×15cm×20cm. The surrounding shrub vegetation was not destroyed during site preparation, and the original forest and grass vegetation around the planting hole was well protected;

[0021] (2) Sowing: Select mature and plump seeds, adopt the method of on-demand sowing, one seed per hole, and cover with original soil after sowing. Sow seeds immediately after soil preparation, without applying base fertilizer;

[0022] (3) Moisture management: Water enough water when sowing, replenish soil moisture according to the weather conditions one week after sowing, and then do not replenish water;

[0023] (4) Pruning: According to the creeping situation, pruning is performed irregularly, and the coverage rate is controlled at about 90%, so that it can obtain sufficient water, nutrients and light resources.

[0024] Embodiment 1~embodiment 2 is according to the...

Abstract

The invention provides a method of ecological restoration of rocky desertification by means of caesalpinia minax. The method comprises following steps: hole-shaped land preparing, during land preparing, original forest grass vegetation around planting holes is well protected; from February to May, performing spot sowing, sowing is performed as land preparing, wherein sowing with 1 to 2 seeds per hole, and covering with original soil after sowing; watering enough during sowing, supplementing soil and water one week after sowing, performing water management according to the soil water content condition in later stage; irregularly performing trimming according to the crawling condition and performing continuous tending and managing, wherein the scope of trimming is determined according to the crawling area; controlling the coverage larger than 90%. The invention is used to solve the problem that the existing rocky desertification control method is slow and the stamina is insufficient. The present invention belongs to the field of ecological management.

Description

technical field [0001] The invention relates to a rocky desertification ecological restoration method, which belongs to the field of rocky desertification ecological control. Background technique [0002] Karst rocky desertification in Southwest China, desertification in Northwest China, and soil erosion in the Loess Plateau are listed as the three major ecological disasters in my country. Karst rocky desertification refers to the disturbance and destruction of human activities in the natural environment background of strong karst development in subtropical regions, resulting in severe water and soil damage. Erosion, large-scale exposure of bedrock, and severe decline in productivity are land degradation phenomena. By the end of 2011, the total area of ​​rocky desertification land in karst areas was 1200.2hm 2 , accounting for 26.5% of the karst land area and 11.2% of the regional land area. The problem of rocky desertification is one of the most significant ecological envi...
