Carbon base fertilizer containing multiple beneficial bacteria and trace elements and preparation method thereof

Abstract

The invention provides a carbon base fertilizer containing multiple beneficial bacteria and trace elements. The carbon base fertilizer is a fertilizer innovatively combining a biomass carbon base withmultiple beneficial bacteria and trace elements, and the fertilizer comprises the following raw materials: the trace element carbon base, an original indigenous bacterial fertilizer, weathered lignite powder, chemical fertilizer and beneficial bacteria. In addition, the carbon base fertilizer containing the beneficial bacteria and the trace elements also comprises a soil remediation microbial inoculum and an organic fertilizer decomposing agent. The trace element carbon base can improve soil hardening, supplement the content of biomass and trace elements in the soil, balance the soil temperature and promote the growth of crops, improve the yield of crops and the quality of agricultural products and ensure the edible safety of agricultural products. The original indigenous bacterial fertilizer can better enrich beneficial bacteria in the soil, can provide a living environment for other later implanted beneficial bacteria to assist other beneficial bacteria to quickly adapt to the soilenvironment and can greatly improve the survival rate of other beneficial bacteria.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a charcoal-based fertilizer containing beneficial bacteria, trace elements and biomass and a preparation method thereof. Background technique [0002] For a long time, most of the cultivated land in my country has been using chemical fertilizers, especially in the Northeast and Central Plains, the main grain producing areas in my country, and the amount of chemical fertilizers has been increasing year by year. Long-term application of chemical fertilizers has wreaked havoc on farmland. Facts have proved that despite the increasing application of chemical fertilizers year by year, the yield of crops tends to decrease year by year, and the quality of agricultural products also decreases year by year. The lack or imbalance of trace elements and beneficial bacteria in the soil leads to the lack of trace elements in agricultural products. The lack of trace elements in ...

Problems solved by technology

However, the above-mentioned fertilizers are composed of a single organic fertilizer or a single beneficial bacterial fertilizer or a single trace element fertilizer, and the effect of using them alone is poor.

Especially due to soil compaction, acidification, pollution and other factors, the microbial activity in the beneficial bacteria fertilizer is poor, and the number of viable bacteria is far less than 200 million / g due to the restriction of the soil environment. The use not only increases the input cost of fertilizers, but also increases labor costs. The single use of the above-mentioned one or two fertilizers cannot achieve the purpose of soil improvement, soil restoration, and improvement of the yield and quality of agricultural products.
