Methods for preparing and applying bioactive fertilizer with grass carbon as raw material

Abstract

The invention discloses methods for preparing and applying a bioactive fertilizer with grass carbon as a raw material. The preparation method is characterized by taking active ingredients including grass carbon and vermiculite as main raw materials, mixing grass carbon with vermiculite in a volume ratio of 1:2, then mixing the mixture with an MMN liquid medium, culturing the materials at a constant temperature of 25 DEG C for 15 days, and then mixing the materials with bioactive carbon, bioorganic fertilizers, a water-retaining agent and bioactive growth promoting ingredients uniformly under aseptic conditions, thus obtaining a solid biological mycorrhiza preparation. Compared with existing biofertilizers, the bioactive fertilizer disclosed by the invention can obviously improve various nutrient element absorbability of plant root systems, promote growth of seedlings, simultaneously improve the tolerance of plants to environments such as drought, saline and alkaline environments, infertility and the like and the capacities of the plants in resisting soil-borne diseases and pests, activate beneficial microorganisms in rhizosphere soil, enhance photosynthesis, improve the carbon fixation capacity of the plants, optimize the quality of the seedlings and increase the market value.

Description

technical field [0001] The invention relates to an active chemical fertilizer and an application method thereof, in particular to a preparation method of bioactive fertilizer using grass carbon as a raw material and a fertilizer application method. Background technique [0002] Mycorrhizal fertilizer is a new type of high-efficiency, non-toxic, green and non-polluting biological fertilizer, which can meet the production of agricultural and forestry products and protect the ecology, and has broad market prospects. [0003] Since the German plant pathologist Frank coined the term mycorrhizae in 1885, the research on mycorrhizae has a history of more than 100 years. Mycorrhizal fungi have a huge mycelium system, and are closely connected with plant roots to form mycorrhizae. They are the most widely distributed and most important type of symbiont in the biological world. Energy, information exchange and transmission are of great significance. At the same time, it has far-reac...

Problems solved by technology

Foreign bacterial fertilizer technology is relatively mature and has been promoted and applied in many fields. However, the soil conditions and commonly used greening tree species in foreign countries are very different from those in my country. etc., and whether it will cause environmental problems such as ecological invasion is also unknown

In addition, it is expensive and difficult to promote in my country's landscaping

[0008] The Pt mycorrhizal agent developed by the Chinese Academy of Forestry—Zhijianbao has a single species, and the effective bacteria are mainly puffballs. The scope of application is narrow, and it cannot meet the huge demand for landscaping.
