Description
Technical Field
The invention belongs to the technical field of soil pollution treatment, and particularly relates to an acidic soil conditioner and a preparation method thereof.
Background
The soil degradation refers to the process of soil property deterioration and productivity reduction caused by unreasonable utilization of soil by human beings, and mainly comprises the forms of soil erosion, soil acidification, alkalization, fertility reduction and the like. With the continuous development of economy, the productivity is severely limited by soil problems, and the problem of soil degradation is increasingly attracting attention of people.
The acid soil is a general term for low pH soil, and includes red soil, brick red soil, yellow soil, red soil, ashed soil, and the like. In acid soil areas, the rainfall is abundant, the leaching effect is strong, the saturation of the base is low, and the acidity is high. The acidic soil in China is mainly distributed in vast tropical and subtropical regions in the south of Yangtze river, Yunhuachuan and other regions, the pH value of most of the soil is less than 5.5, a large part of the soil is less than 5.0, even 4.5, in recent years, the acid rain settlement, the use of a large amount of ammonium nitrogen fertilizer and the like cause the soil to have a sharp acidification trend, the area of the acidic soil is enlarged, and the acidity of the soil is continuously increased.
The adverse effect of acid soil and soil acidification on agricultural production is mainly shown in the following aspects, the first is that hydrogen ions are directly poisoned, when the pH value is less than 4, the direct poisoning effect on plant growth can be generated, the number of roots is reduced, the roots are shortened and thickened, and in severe cases, the root tips are dead. After the overground part is seriously damaged in the root system, the growth of the plant is inhibited, and finally, the leaves wither until death. Secondly, the aluminum poisoning phenomenon is common on acid soil in both paddy fields and dry lands, the root system is the most sensitive part damaged by the aluminum poisoning, and when the concentration of soluble aluminum ions in a soil solution exceeds a certain limit, the aluminum poisoning symptom can appear: the growth of root systems is obviously hindered, the roots are short and small, are deformed and curled, are fragile and easy to break, and the growth of the overground parts of plants is inhibited immediately afterwards; thirdly, manganese poison, which is the first symptom of the toxicity of plant manganese on acid soil, appears on the overground part, and shows that leaves are green, tender leaves are yellow, and necrotic spots appear in severe cases. The old leaves poisoned by manganese often have black spots, and the black spots are proved to be the deposition of manganese dioxide through section observation and component analysis; fourthly, on acid soil, the effectiveness of soil nutrients is reduced, for example, the effectiveness of N, P, K, Ca, Mg and Mo is greatly reduced, and the effectiveness of various nutrients is higher when the pH value is about 6.5, so that the fertilizer is suitable for the growth of various crops.
In the process of implementing the embodiment of the invention, the inventor finds that at least the following defects exist in the background art:
the existing method for improving acid soil in production is to apply soil conditioner such as quicklime on the surface of soil and then mix the soil conditioner with plough layer soil, and the method has the following defects: if the quicklime is unevenly applied, the quicklime can directly contact plant spores to influence the rate of emergence or cannot emerge, and if the quicklime is directly contacted with plant roots, seedlings are burnt and roots are rotten; the solubility of quicklime is low, the mobility of the quicklime on a soil profile is slow, the soil hardening can be caused by applying the quicklime in a large amount or for a long time, and the crop yield reduction can be caused by the imbalance of elements such as calcium, potassium, magnesium and the like in the soil; excessive application of quicklime reduces the absolute soil moisture content, resulting in water shortage for plants, a phenomenon commonly known as lime "seedling burning"; in the initial stage of mixing quicklime into soil, the pH index of the soil can be rapidly increased, and the biological properties of the soil are destroyed.
In addition, the application of the current soil conditioner is basically carried out in a small quantity of multiple application modes, so that the agricultural production cost is undoubtedly increased, the popularization and the application in broad planting farmer groups are not facilitated, and the problem of soil acidification is difficult to fundamentally solve.

The biochar is a solid product generated by pyrolysis of biomass at a certain high temperature (under an oxygen-free or oxygen-deficient condition), has the characteristics of porosity, high carbon content, large specific surface area, alkaline property and the like, and has a certain improvement effect on acid soil. The physicochemical properties of the biochar directly determine the functions of the biochar, and the materials involved in the preparation process of the biochar and the preparation conditions such as time, temperature, oxygen content and the like directly determine the physicochemical properties of the biochar.
While natural polymer compounds such as starch and the like are generally used as soil conditioners, the common crop conditioners made of natural polymer compounds are easily decomposed by microorganisms in soil, release more cations and have great toxic effect on the soil; the application amount is large in the early stage, the cost is high, and the popularization is difficult in production.
Therefore, the inventor prepares the biomass charcoal by using the rice straws, and the alkaline porous biomass charcoal is obtained by mixing and modifying the biomass charcoal and carbonizing the biomass charcoal at the temperature of not less than 500 ℃.

The conditioner obtained in the embodiment of the invention can effectively improve the soil environment, has obvious effects on reducing the volume weight of soil, increasing the pH value, increasing the content of water-stable aggregates and the like, and has good adhesion of soil particles and improvement of the granular structure of the soil by observing the apparent appearance of the soil before and after planting and attaching fine particles in the soil to the surface of large particles. Compared with the comparative examples 1-2, the limestone group and the blank control group of the changed raw materials, the yield and the quality of the strawberry and the soil structure are greatly reduced, and the planting effect is not good.
It should be noted that the above-mentioned embodiments are only some of the preferred modes for implementing the invention, and not all of them. Obviously, all other embodiments obtained by persons of ordinary skill in the art based on the above-mentioned embodiments of the present invention without any creative effort shall fall within the protection scope of the present invention.
