Abstract

The invention provides an acidic soil conditioner, and a preparation method and application thereof. The acidic soil conditioner comprises the following components in part by weight: 4 to 8 parts of composite bacterial agent, 80 to 90 parts of acid adjusting factor, 3 to 7 parts of chelate and 2 to 6 parts of organic matter. The acidic soil conditioner adjusts the pH value of soil, promotes formation of soil aggregate structures, improves the physical property of the soil, creates a good ecological environment for the growth of plants, increases organic matters, calcium, magnesium and silicon and the activities thereof, promotes healthy growth of crops, enhances stress resistance and prevents diseases and pests. By adoption of the composite bacterial agent, the constitution of a microflora of the soil can be improved, the microbial activity of the rhizosphere of the crops is enhanced, mineralization of organic pollutants is accelerated, growth of the plants is promoted, and absorption of degradation products and bioremediation of the polluted soil are accelerated. The acidic soil conditioner has no toxicity, residues and pollution, accords with the development tendency of organic pollution-free agriculture and has great popularization and application values.

Description

technical field [0001] The invention relates to the field of microbial soil conditioning and restoration, in particular to an acidic soil conditioner and its preparation method and application. Background technique [0002] According to Hunan Province's longitudinal comparative analysis of the pH values ​​of 13,000 soil samples corresponding to the second soil survey in the early 1980s, the average pH value of the cultivated land in the province dropped from 6.46 to 6.02, a drop of 0.44 units, equivalent to soil Acid content (H + ) increased by 1.94 times on the original basis. The area of ​​extremely acidic cultivated land with a pH value < 4.5 increased from 261,800 mu to 538,800 mu, an increase of 105.81%; 196.70%, indicating that the trend of soil acidification is obvious. The so-called soil acidification refers to the process in which the base ions in the soil are leached or taken away by crops, and the concentration of hydrogen ions increases and the acidity incr...
