Problems solved by technology

[0004] At present, the control method of rocky desertification is mainly to plant foreign soil to control sand, but because foreign soil is easily carried away by wind and sand, or washed by rain, water and soil are easy to lose, it is often difficult to succeed, and the cost is high, so it has not been widely used.

Embodiment 1

[0044] A rocky desertification control method, comprising the following steps:

[0045] S1. Terrain finishing

[0046] Clean up scattered stones, and excavate and backfill local uneven areas.

[0047] S2. Soil improvement

[0048] Lay a layer of isolation layer on the leveled ground; then fill the isolation layer with a soil improvement layer; and finally lay a guest soil layer.

[0049] The isolation layer includes a gravel layer, a straw layer and a rocky desertification soil layer from bottom to top. The thickness of the isolation layer is 10cm.

[0050] The soil improvement layer is formed by mixing the improvement agent and soil. The percentage by weight of the modifier in the soil modification layer is 15%. The soil improvement layer is 20cm.

[0051] The rocky desertification soil is used as the soil in the soil improvement layer, specifically, the rocky desertification soil is uniformly mixed with straw, animal manure, fungal residue and microbial agent to be use...

Embodiment 2

[0068] A rocky desertification control method, comprising the following steps:

[0069] S1. Terrain finishing

[0070] Clean up scattered stones, and excavate and backfill local uneven areas. Expand the rock pits naturally formed in rocky desertification areas to form planting pits not smaller than 60cm×70cm×60cm.

[0071] S2. Soil improvement

[0072] Lay a layer of isolation layer on the leveled ground; then fill the isolation layer with a soil improvement layer; and finally lay a guest soil layer.

[0073] The soil improvement layer is formed by mixing the improvement agent and soil. The isolation layer includes a gravel layer, a straw layer and a rocky desertification soil layer from bottom to top. The thickness of the isolation layer is 20cm. The percentage by weight of the modifier in the soil modification layer is 20%. The soil improvement layer is 20cm.

[0074] The rocky desertification soil is used as the soil in the soil improvement layer, specifically, the r...

Embodiment 3

[0091] A rocky desertification control method, comprising the following steps:

[0092] S1. Terrain finishing

[0093] Clean up scattered stones, and excavate and backfill local uneven areas. Expand the rock pits naturally formed in rocky desertification areas to form planting pits not less than 60cm×50cm×70cm.

[0094] S2. Soil improvement

[0095] Lay a layer of isolation layer on the leveled ground; then fill the isolation layer with a soil improvement layer; and finally lay a guest soil layer.

[0096] The isolation layer includes a gravel layer, a straw layer and a rocky desertification soil layer from bottom to top. The thickness of the isolation layer is 10cm.

[0097] The soil improvement layer is formed by mixing the improvement agent and soil. The percentage by weight of the modifier in the soil modification layer is 30%. The thickness of the soil improvement layer is 25cm.

[0098] The rocky desertification soil is used as the soil in the soil improvement lay...

Abstract

The invention provides a stony desertification treatment method, and relates to the technical field of ecology. The method includes the following steps of arranging the terrain, improving soil and planting crops. By means of the treatment method, a stony desertification region is flattened, a planting structure is reestablished, and an isolation layer is laid on the flattened ground; a soil improving layer is laid on the isolation layer; finally, an out-soil layer is laid. The isolation layer, the soil improving layer and the out-soil layer together have effects of water retention and water and soil loss reduction, plant growth is promoted on the premise of improving soil, the ecological environment is further improved, and the further deterioration of stony desertification is prevented.

Description

technical field [0001] The invention relates to the field of ecological technology, in particular to a rocky desertification control method. Background technique [0002] Karst landforms are widely distributed in Guangxi. The area of ​​karst areas in the whole region is 125 million mu, accounting for 35.2% of the region's land area, involving 779 townships (forest farms) in 76 counties (cities, districts) in 10 cities. In the land area of ​​karst areas, rocky desertification land reaches 35.68 million mu, ranking third in the country, second only to Yunnan and Guizhou. The population of the karst area is more than 12 million, accounting for about a quarter of the total population of Guangxi. Due to the severe rocky desertification, the local economic and social development is very lagging behind. More than 90% of the poor population in Guangxi are distributed in rocky desertification areas. [0003] With the passage of time, the degree and area of ​​"rocky desertification"...
