Description
Technical Field
The invention relates to the field of soil improvement, in particular to an acid soil conditioner and a preparation method thereof.
Background
The soil improvement is a process of adopting corresponding physical, biological or chemical measures aiming at the bad texture and structure of soil, improving the soil property, improving the soil fertility, increasing the crop yield and improving the soil environment for human survival. Soil acidification is a manifestation of soil degradation, and refers to a natural phenomenon in which soil acidification is increased and becomes strongly acidic or very strong. The low pH value of the soil can affect the physicochemical property of the soil, thereby indirectly affecting the growth and development of plants. Soil peracid causes soil hardening, sticky and heavy texture, soil structure is damaged, air permeability is poor, soil biological diversity is changed after soil acidification, effectiveness of nutrients in soil is reduced, cations are lost, and nutrient elements such as phosphorus, potassium, calcium, magnesium, molybdenum, boron and the like are deficient, so that soil nutrient imbalance and fertility are reduced. And the reduction of the pH value of the soil can activate toxic heavy metal elements to poison crops, so that the growth and development of the crops are poor, the yield of the crops is reduced, the quality of products is reduced, and the potential threat of the heavy metal elements to agricultural production and ecological environment is increased. In the prior art, although various acid soil conditioners exist, the improvement effect is poor, the application amount is large, and the fertilizer efficiency is reduced when the acid soil conditioners are applied together with chemical fertilizers.
