Abstract

The invention relates to the technical field of soil improvement, and concretely discloses a saline-alkaline land soil conditioner, and a preparation method and an application thereof. Raw materials of the conditioner comprise 400-600 parts of a biomass decomposed material, 150-242 parts of a pyroligneous liquor, 200-300 parts of charcoal powder, 4-10 parts of urea and 2-10 parts of a microbial agent. All the components are synergistically combined, so the conditioner contains abundant organic matters, provides favorable conditions for crop growth, can improve the physical and chemical properties of the soil and slowly release nutrients, improves the fertilizer utilization rate and the water holding capacity of the soil, effectively reduces the pH value of the soil and the salt content ina soil solution, delays accumulation of salt in the surface soil, and has a good improvement effect on saline-alkaline land soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for saline-alkali land, a preparation method and an application thereof. 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. Soil salinization is a prominent ecological environmental problem in the world's dry farming areas. According to incomplete statistics, the area of ​​saline-alkali land in the world has reached 1 billion hectares, of which my country has 99.14 million hectares, ranking third in the world. According to the research, when the soil is at the level of moderate saline soil (salt content between 0.3% and 1.0%), the yield of crops will be reduced by about 95%, and the planting situation in severely saline-alkali land is even more severe. For example, in the area of ​​Hetao Plain in Inner Mongolia, the average annual death ra...
