Soil conditioner plays an important role in improving obstacle soil.

Soil acidification has become an important factor affecting agricultural production and ecological environment. Soil acidification begins with active protons (H+). Due to the instability of the nature of hydrogen clay, when the hydrogen ions adsorbed on the surface of soil organomineral-mineral complexes or aluminosilicate clay minerals reach a certain limit, the lattice structure of these particles will be destroyed, and the aluminum-oxygen octahedra will disintegrate, so that aluminum ions will break away from the octahedral lattice and transform into exchangeable aluminum ions. The hydrolysis of exchangeable aluminum in soil makes soil show acidity characteristics. According to the degree of hydrolysis, one hydrolysis of Al3+ can produce 1~3 hydrogen ions. Weathering of primary and secondary minerals containing aluminum in acidic soils also accelerates the release of large amounts of aluminum ions, forming aluminum compounds that can be absorbed by plants. Excessive absorption of aluminum by plants will not only reduce the quality of crop products, but also greatly affect the growth of plants, especially plant roots, and even lead to plant poisoning death. Acidification can also enhance the fixation of phosphate and molybdate in soil, reduce the availability of phosphorus and molybdenum in soil, and affect the normal growth and development of plants.

Soil salinization (alkalization) refers to the process in which the salt in the bottom soil or groundwater rises to the surface with capillary water and accumulates in the surface soil after evaporation of water. Soil salinization not only destroys soil structure, but also adversely affects crop growth and soil microbial activity. Because salt accumulates in the surface soil, it increases the osmotic pressure of soil solution, reduces the osmotic pressure difference with crop roots, and then affects the normal absorption of water and nutrients by crops.

Soil drought has become a common condition in certain areas or in certain crop-growing areas. China's arid areas account for 30.8% of the country's land area, concentrated in the northwest, with the largest area of **, the total amount of agricultural water consumption of ** is 77.8 billion m3, accounting for 90% of the total water consumption. Drought can further deteriorate the ecological environment and easily trigger other natural disasters.

Soil biological barrier is a phenomenon in natural or farmland ecosystem that plant-soil interaction causes soil biological population to change adversely to the growth and development of a plant. Continuous cropping obstacle is one of the main manifestations of soil biological obstacle. Continuous cropping increased harmful microorganisms in soil, caused serious soil-borne diseases and insect pests, and caused changes in the population and quantity of soil microorganisms. In addition, there are certain interactions between soil biological barrier factors and soil physical and chemical properties. Continuous cropping obstacles can reduce the yield and quality of peanut, tobacco and vegetables, and reduce economic benefits.

The application of soil conditioner is one of the main measures to restore degraded soil

1, improve soil quality, so that acidification, salinization, hardening, excessive fertilization of soil vitality.

2, improve soil continuous cropping obstacles, provide suitable soil environment for growth, conducive to soil virtuous cycle.

3. Improve crop yield, improve quality, reduce flower and fruit drop, improve seed setting rate, harvest early and prolong picking period, increase fruit nutrition level, and have good commodity quality.

4. Prevent diseases and insect pests and pathogens from harming plants, and enhance disease resistance, antibacterial and stress resistance.

5, decomposition of soil, plant fertilizer, pesticide residues, passivation of heavy metals on environmental pollution.

6. Improve soil water retention and soil adsorption performance.
