Desertification Control


Structural soil improvement technology Pioneer plant enclosure creation technology





Biological management techniques: forestry and grass planting to maintain water and soil; forest belt creation to prevent wind and sand; small watershed management to protect the shore and preserve the beach.

Engineering management techniques: mixed spray vegetation technology, plant mat plant blanket technology, etc.


Plant breeding technology determines the survival rate and growth development of plants. It mainly includes tree species treatment and selection techniques, plant breeding techniques.

Establish artificial isolation zone, artificial control combined with biological and chemical control.


Spraying technology Biological sand barrier technology





Special spraying equipment is used to spray homemade substrates, nutrient solution and seeds evenly respectively. Mainly sowing sandy plants, which are characterized by low water transpiration, well-developed mechanical and transporting tissues, can resist wind attacks and transport water and nutrients to the much-needed organs as soon as possible, and often maintain high osmotic pressure in their cells, which have a strong ability to continuously absorb water, making the plants less prone to water loss and able to adapt to the environment of drought and little rain.

Set up plant mats sand barriers, "plant mats" in the growth of plants to fix sand. Plant blanket cover grows woody, herbaceous or forestry economic plants. Plant mat of trees on the flowing dunes tied into a wind-blocking wall to weaken the wind erosion, while having the effect of intercepting rainfall, can absorb ecological water, with anti-transpiration system, improve the water content of the sand layer, conducive to the growth of sand plants. It has better sand fixation effect and good water retention capacity.


Saline Land Treatment


The development and management of saline land should be tailored to local conditions, according to the causes of saline soil, characteristics, use purposes and combined with the local climate, economic and other conditions, in a certain area of the saline land for integrated planning, comprehensive management.


Deep Tillage and Deep Pine

Loosens topsoil, enhances water permeability and air permeability, and stops the rise of water and salt.

Preventing soil slumping, improving soil agglomeration structure, and

Retain water and fertilizer and reduce salt hazard.


Regional drainage

With storage as the main focus, the distribution of salt in the soil is changed through cyclic salt pressure to achieve the goal of transferring salt to deeper layers and reducing the salt content of the cultivated layer, while ensuring sufficient water resources within the soil through proper water storage to reduce pollution of downstream water bodies and achieve ecological goals.


Plant mat guest soil pressure alkali

Plant mats containing guest soil, organic fertilizer, sand, base material and salt-tolerant plant seeds are laid in the treatment area to improve the soil through the patented plant mat technology.

Guest soil-improves the physical properties of saline land so that the saline in the original soil can no longer be brought to the surface soil by the action of capillary water, and has the effect of salt suppression, salt drenching, alkali pressure and increasing soil fertility.

Organic fertilizer - increase the humus of the soil is conducive to the formation of granular structure, improve the aeration, water permeability and nutrient status of saline land, and the organic acid produced by the decomposition of organic matter can also neutralize the alkalinity of the soil.

Bottom layer of sand and alkali pressure-lower capacity, increase porosity and soil water content, regulate soil water, fertilizer, gas and heat, decrease soil pH and conductivity, and reduce soil salt return. It creates a good ecological environment for plants to grow on saline soil.

Salt-tolerant plant seeds-salt-tolerant plants grow by absorbing the substrate in the plant mats, which can weaken the evaporation of surface water. In addition, plants turned into the soil can increase the organic matter content and produce various organic acids, which play a certain neutralizing effect on soil alkalinity.

Plant mat - Plant mat surface material can gather salt and block salt to achieve the effect of inhibiting the return of salt to the soil, thus effectively preventing the accumulation of salt to the surface.


Irrigation and salt washing

The use of natural precipitation or artificial large water irrigation can prompt some salinity to penetrate downward along the soil pores and cracks, bringing the salts of the topsoil to the bottom layer with the water. After irrigation, the topsoil can be stirred to increase the dissolution of salts as a way to improve the desalination rate.
