Soil conditioner and preparation method thereof

Abstract

The invention discloses a soil conditioner and a preparation method of the soil conditioner, and belongs to the soil field. The soil conditioner is obtained by roasting at least one type of marine organism shells used as raw materials at 800-1200 DEG C. The marine organism shells are optimally oyster shells. The soil conditioner prepared through the preparation method has super strong adsorption and regulation capabilities, improves the physical and chemical properties of soil, and enables the soil to form a good granular structure; the effectiveness of macroelements and microelements is improved, therefore, the fertilizer rate is reduced, and crop output can be increased remarkably; the activity of toxic substance in the soil can be passivated remarkably, so that the phenomenon that aluminum ions cause a crop root system to be poisoned, rotted and dead is greatly reduced, and the capability of crops for stress resistance and resistance to diseases and pests is enhanced; physiological diseases of various crops can be effectively prevented and treated, beneficial cenobium in the soil can multiply at a high speed, and therefore the ecological restoration function of the soil is achieved.

Description

technical field [0001] The invention relates to the field of soil technology, in particular to a soil conditioner and a preparation method thereof. Background technique [0002] The impact of natural conditions, long-term high-intensity cultivation and large-scale application of quick-acting fertilizers lead to soil structure deterioration (such as soil compaction, desertification, etc.), nutrient imbalance, and soil fertility decline. In addition, these factors also cause serious soil acidification, which seriously affects the effectiveness of fertilizers (that is, no matter what fertilizer is applied, for example, there is still phosphorus deficiency after applying phosphorus fertilizer, and potassium deficiency after applying potassium fertilizer). Secondly, heavy metal pollution in soil is becoming more and more serious. Heavy metals such as cadmium and mercury will enter crops and affect human health. [0003] Faced with the serious deterioration of this soil, people h...

Problems solved by technology

But this soil conditioner also has following shortcoming: the one, above-mentioned effect is limited, just improved to a certain extent, also has the space for further improvement, the 2nd, the composition of this soil conditioner is more complicated, the acquisition of raw material Relatively difficult, high cost, not conducive to large-scale application and promotion

[0004] In addition, in the coastal area, after a large amount of marine biological soft bodies are used, a large number of marine biological shells are left, such as shells, clam shells, oyster shells, etc., especially oyster shells. Currently, no marine biological shells such as oyster shells have been found. Appropriate utilization methods have caused serious environmental pollution
