Abstract

The invention provides an acidic soil conditioner, a preparation method and application thereof. The acidic soil conditioner is formed by compounding of industrial waste, mineral raw materials and anSE functional material in certain proportion. The SE functional material comprises a glucoamylase treatment substance and amino acid biochar, as well as one or more of alginic acid, polyaspartic acid,polyglutamic acid and potassium fulvate. The acidic soil conditioner provided by the invention can effectively adjust the soil pH value, neutralize free acid, passivate activated aluminum, and solvethe problems of "acidity and toxicity" of soil; being rich in humic acid and organic matters, the acidic soil conditioner can effectively improve soil, restore the granular structure, increase the content of organic matters, and improve the water retention, fertility increasing and breathability of soil; the acidic soil conditioner can improve the rhizosphere soil microenvironment, enhance root activity, and promote nutrient uptake and utilization, also can improve the crop stress resistance and effectively prevent crop premature senescence, thus being a conditioner having the efficacy of improving soil and promoting crop growth.

Description

technical field

[0001] The invention relates to the technical field of soil improvement and fertilizers, and more specifically relates to an acidic soil conditioner and its preparation method and application. Background technique

[0002] Acidic soil is soil with a pH of less than 7. The acidic soil in my country is mainly distributed in the vast tropical and subtropical regions south of the Yangtze River, with an area of ​​about 2.04×10 8 hectare. Among them, the pH value of most soils is less than 5, and some are even as low as below 4.5. What's more serious is that the area of ​​acidic soil is still expanding, and the acidity of soil is also rising. Soil acidification will lead to a series of soil physical, chemical, and biological environmental changes, such as the destruction of good soil structure, compaction, changes in microbial population structure, and the activation of toxic metal elements such as aluminum and manganese. The soil buffer performance will decreas...
