Efficient saline-alkali soil repair agent

Abstract

The invention provides an efficient saline-alkali soil repair agent which is good in effect, short in time and free of pollution. The efficient saline-alkali soil repair agent is characterized by being prepared from calcium oxide, silicon dioxide, aluminium oxide, sulfur trioxide, ferric oxide, magnesium oxide, titanium dioxide, potassium oxide, manganese oxide, sodium oxide and water. Natural mineral substances serve as main raw materials. The efficient saline-alkali soil repair agent is green, environmentally friendly and free of pollution. The PH value of repaired soil can be kept neutral after the efficient saline-alkali soil repair agent is used, plant growth is not influenced, and secondary pollution to the surrounding can be avoided. The soiled repaired through the efficient saline-alkali soil repair agent is good in water-retaining property and fertilizer-retaining property. The efficient saline-alkali soil repair agent can be used for repairing sandy lands and arid lands. Repaired soil can not be dissolved in water before and after being repaired, water and soil loss can be prevented, malodor in soil can be closed, harmful substances can be solidified, and harmful substances can be prevented from flowing out and causing pollution to the surrounding. The efficient saline-alkali soil repair agent is low in cost and high in speed, soil repair can be completed within only one week, the repair effect is stable and durable, and an operation system is small and efficient.

Description

technical field [0001] The invention relates to the field of saline-alkali improvement, in particular to a high-efficiency saline-alkali restoration agent. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. From the perspective of soil structure, saline-alkali land is all compacted soil. The air permeability and water permeability of the soil are very poor, and the salt is mixed in In compacted soil, it is difficult to be separated, resulting in precipitation year by year, and the salt content is getting higher and higher. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares is in my country. Most of saline-alkali land in my country is flat, deep soil, suitable for machine farming and has potential fertility, which is a kind of precious land resources. Th...

Problems solved by technology

my country attaches great importance to the improvement of saline-alkali land. There are currently four main improvement methods, water conservancy improvement, agricultural technology improvement, biological improvement, and chemical improvement. Although these improvement methods have certain effects, they are costly and take a long time to improve. Generally, it takes 3 - It takes 5 years to see the effect; especially chemical improvement, which indirectly causes environmental pollution, and the improvement effect is not ideal
