Acidic soil conditioner and preparation method thereof

Abstract

The invention provides an acidic soil conditioner. The soil conditioner is prepared from the following raw materials in parts by weight: 80-100 parts of livestock and poultry dropping, 30-50 parts of sulfur powder, 30-50 parts of aluminum sulfate, 20-40 parts of corn stalks, 20-40 parts of paddy stalks, 30-50 parts of humic acid, 20-40 parts of ferrous sulfate, 20-40 parts of sulfur, 20-40 parts of calcium carbonate, 20-40 parts of silicic acid, 15-30 parts of decomposed coal, 10-20 parts of oil shale and 10-20 parts of complex microbial inoculants. The finished product is prepared by pre-treatment, turning and stirring, temperature control and fermented treatment. The soil conditioner can be used for promoting moisture and nutrition absorption of plant roots, improving the granular structure performance of soil and regulating the pH value of soil. The soil conditioner breaks through the acting mode of a traditional soil conditioner, can be used for treating primary and secondary causes and radically improving the ecological environment of soil, and enables the oil to reach a healthy state.

Description

technical field [0001] The invention relates to the field of soil conditioning, in particular to an acidic soil conditioner and a preparation method. Background technique [0002] As mankind enters the 21st century, the development of science and technology has reached a new stage, which has greatly promoted the progress of social economy. On the other hand, the problems faced by mankind are still very prominent, such as climate change, land desertification, salinization, environmental pollution and so on. In developing countries, due to the increasing population and decreasing arable land, a large number of forests, grasslands, wetlands, etc. have been reclaimed as arable land for intensive management, destroying the original vegetation and soil structure, leading to land salinization. At the second international conference on sustainable development held in Johannesburg in September 2002, it was pointed out that 10 years after the first international conference on susta...

AI Technical Summary

Problems solved by technology

The pH value of the soil in saline-alkali land is generally above 8.0. Even if there are rich nutrients in the soil, its absorbability is very low.
