Description

Silicon-calcium-magnesium-sulfur matrix composite biological enzyme fertilizer mate and preparation method and application thereof Technical Field The invention belongs to the technical field of agricultural fertilizers, and particularly relates to a silicon-calcium-magnesium-sulfur matrix composite biological enzyme fertilizer mate, a preparation method and application thereof. Background With the rapid development of modern agriculture, chemical fertilizers are increasingly widely applied in agricultural production. The fertilizer can rapidly provide the crops with the required nutrient elements, and the crop yield is obviously improved. However, a series of problems are caused by the long-term large-scale use of chemical fertilizers, on one hand, the utilization rate of the chemical fertilizers is generally low, a large amount of nutrients are lost through volatilization, leaching, fixation and other ways, not only are resource waste caused, but also environmental problems such as soil and water pollution are caused, on the other hand, the single dependence on the chemical fertilizers can cause soil degradation problems such as soil organic matter reduction, structural damage, weakening of water and fertilizer retaining capacity, soil hardening, acidification and the like, and further the crop growth and the quality of agricultural products are influenced. Silicon, calcium, magnesium and sulfur are medium elements necessary for crop growth, silicon can enhance crop disease and pest resistance and lodging resistance, improve photosynthesis efficiency, calcium is an important constituent of cell walls and participates in cell division and growth, magnesium is a core element of chlorophyll and directly influences photosynthesis, sulfur is a constituent element of protein and enzyme and participates in various physiological metabolic processes. The silicon, calcium, magnesium and sulfur elements not only directly participate in the growth and development of crops, but also can improve the physicochemical properties of soil and the water and fertilizer retaining capacity of the soil. The biological enzyme is a kind of bioactive substances with catalytic function, and can promote organic matter decomposition, nutrient transformation and improve the micro-ecological environment of the soil in the soil. Research shows that the application of the exogenous enzyme preparation can accelerate the nutrient circulation of soil, improve the nutrient availability, promote the root growth and enhance the nutrient absorption and utilization of crops. At present, the synergistic products on the market are focused on a single carrier or a single functional component, the exogenous enzyme preparation is easy to be inactivated by the influences of factors such as temperature, moisture, salinity, pH and the like in the processes of storage, transportation and mixing with chemical fertilizers, and is easy to be leached and migrated in soil, so that the synergistic products have short duration of action and low utilization efficiency, and lack a fertilizer synergistic product which can simultaneously exert the nutrition functions, the soil improvement functions and the biological synergistic functions of medium and trace elements, and is convenient to use in combination with chemical fertilizers and moderate in cost. Therefore, the person skilled in the art is desirous of developing a fertilizer synergistic product which can combine the carrier slow release/fertilizer retention and soil moisture retention and enzymatic conversion synergistic, and promote the sustainable development of agriculture.
