Description
Technical Field
The invention relates to the technical field of agricultural soil, in particular to a soil conditioner and a preparation method thereof.
Background
Soil in southern areas of China is mostly acid soil, due to the fact that farmers use fertilization habits to apply nitrogen fertilizers partially and pay no attention to balanced fertilization, long-term unreasonable fertilization measures such as less organic fertilizer application and the like cause soil hardening and soil fertility reduction, in recent years, acid rain settlement, large amount of ammonium nitrogen fertilizers and the like cause the soil to be in a sharp acidification trend, the acid soil area is enlarged, the soil is further acidified, soil ecology is damaged, and therefore the problems of low crop yield, poor quality of agricultural products, low fertilizer utilization rate and the like are caused. In addition, acid soil areas in south China including acid soil areas such as red soil, brick red soil, yellow soil, red soil and ashed soil have abundant rainfall, strong leaching effect, low base saturation and serious soil nutrient loss, the requirement of crops on nutrients can be met only by increasing fertilizer input, and the soil structure can be improved by applying the soil conditioner, the mineral nutrients in the soil are activated, the soil fertility level is improved, and the absorption and utilization of the nutrients by the crops are promoted.
The seaweed processing industry in coastal areas of China comprises various industries such as seaweed processing food, medicines, chemicals and the like, and a large amount of seaweed residues, which are wastes after seaweed processing, are accumulated and are not effectively treated. The seaweed residues are rich in certain seaweed functional active substances, have a stimulating effect on the growth of crops, can be used as a culture medium of microorganisms to propagate beneficial soil microorganisms, are prepared into a beneficial soil microorganism microbial agent and added into a fertilizer for application, are beneficial to improving the soil microbial community structure, and promote the growth of the root system of the crops and the absorption of nutrients.
In south China, dry lands such as Guangdong, Guangxi and Yunnan have more sugarcane and sweet corn, a large amount of wastes such as sugarcane leaves, sugarcane tips and corn stalks are left after harvesting, farmers are usually used to directly burn the wastes on the spot to cause a large amount of air pollution, and the direct stack retting without burning needs to occupy a large amount of space and is difficult to decompose. Therefore, how to effectively recycle the sugarcane and corn wastes is always a problem. The carbonization of the wastes to prepare the biochar applied to the soil is a good soil regulation mode, which is beneficial to improving the soil and improving the nutrient absorption of crops.
The invention fully utilizes the seaweed residues, the sugarcane and the corn wastes and the like for processing, simultaneously fully utilizes the sugar mill waste, namely the filter mud, and processes and prepares the soil conditioner, thereby being used as a soil conditioner for realizing circular agriculture, being beneficial to protecting the ecological environment and reducing the resource waste.
