Biological active fertilizer taking branch and fallen leaf of poplar as raw materials and application method thereof

Abstract

The invention discloses a biological active fertilizer taking the branches and fallen leaves of poplar as raw materials and an application method thereof. The effective component of the biological active fertilizer takes the branches and fallen leaf crushed substances of the poplar and vermiculite as main raw materials. The preparation method comprises the following steps of: mixing the branches and fallen leaf crushed substances of the poplar and the vermiculite according to the volume ratio of 2:1, and then mixing into MMN liquid culture medium; inoculating multiple ectomycorrhizal fungus, and then uniformly mixing with biological active carbon, a biological organic fertilizer, a water retention agent and a biological active growth-promoting component under an aseptic condition to obtain a solid biological mycorrhiza formulation. Compared with the traditional biological fertilizer, the biological active fertilizer disclosed by the invention can obviously enhance the absorption of multiple nutrient elements of a plant root system, promote the growth of a seedling, enhance the tolerance and soil-borne diseases and insect pests resistant capacity of a plant on a drought environment, a saline-alkali environment, an impoverished environment, and the like, activate the beneficial microbes contained in rhizosphere soil, enhance the photosynthesis, enhance the carbon sequestration capacity of the plant, optimize the seedling quality 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 bioactive fertilizer and an application method using poplar branches and fallen leaves as raw materials. 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-reaching economi...
