Embodiment Construction

[0011] see figure 1 The improvement of the desert is first implemented in the border areas of the desert. First, use a bulldozer to clean up the surface sand layer to a depth of about 1.1m underground, then level the bottom sand layer 7 at the bottom of the land, and use a ramming machine to properly add water to ram it, every 50m It is a width unit, the two sides are slightly higher, and the middle is slightly lower. Dig a ditch with a width of 1 meter and a depth of about 0.3 meters in the middle of the bottom sandy soil 7. After digging, fill the gravel in the ditch as the drainage ditch 6, and then The upper part of the sandy soil 7 zone is paved with a 0.15m thick clay layer 5, and the planting soil layer 4 is filled above the clay layer 5. The thickness of the planting soil layer 4 remains at about 1.0m, and the crops 2 are planted on the planting soil layer. The water in the layer evaporates too fast, and it is necessary to cover with mulch, or build a greenhouse 1 for ...

Abstract

The invention discloses an earth surface planting desert reforming technology, which aims to provide a technology which can improve the soil texture of the desert, prevent and fix sands, and gradually reform a desertified land into a land with good-quality soil. The invention has the technical scheme that the technology is implemented at the edge part of the desert area to be reformed, the surface layer of sandy soil is cleared up, the lower bottom layer sand is appropriately added with water for tamping, a clay layer with the thickness of 0.15 m is filled on the bottom layer sandy soil, a planting soil layer with the thickness of 1.0 m is filled on the clay layer, plants are planted on the planting soil layer, and a mulching film is paved or a greenhouse is constructed on the earth surface so as to reduce quick water evaporation.

Description

technical field [0001] The invention relates to a technology for improving deserts, in particular to a technology for improving deserts by planting on the ground. Background technique [0002] The total area of ​​desertified and wind-sandified land in China is 17.85% of the total land area. Among them, the area of ​​desert is 483,200 square kilometers, the area of ​​Gobi is 710,700 square kilometers, the area of ​​wind-eroded mounds and desertification area is 434,200 square kilometers. They are mainly distributed in 7 provinces including Xinjiang, Qinghai, Gansu, Inner Mongolia, Shaanxi, Jilin and Heilongjiang, which shows that the problem of desertification in our country is very serious. Although we know that our country is the country with the largest afforestation area in the world, even so, the perfect country is also one of the countries with the most serious land desertification in the world. The area of ​​land desertification is in a continuous growth trend, and th...
