Compound microorganism fertilizer suitable for leguminous plants

Abstract

The invention discloses a compound microorganism fertilizer suitable for leguminous plants. The compound microorganism fertilizer is prepared from, by mass, humic acid, yeast powder, purple non-sulfurphotosynthetic bacteria, organophosphorus bacteria, potassium sulphate and calcium superphosphate. According to the compound microorganism fertilizer, the soil fertility can be improved, and throughthe synergistic effect between nitrogen-fixing bacteria and purple non-sulfur photosynthetic bacteria in the leguminous plants, the dinitrogenase activity of root nodules and the soil nitrogen fixingstrength can be improved; besides, the nitrogen-fixing bacteria can promote the phosphorus-dissolving capability of the organophosphorus bacteria, and formation of water-soluble phosphorus in soil isfacilitated; long-term improvement of the soil can be achieved, through the synergistic effect between the nitrogen-fixing bacteria and purple non-sulfur photosynthetic bacteria in the leguminous plants, increase of other soil microorganisms can be promoted, the microorganism environment in the soil is improved, and durable fertilizer efficiency is generated; the infection of pest diseases can belowered, and through the synergistic effect between the nitrogen-fixing bacteria and purple non-sulfur photosynthetic bacteria in the leguminous plants, the infection of soybean cyst nematode diseasesis alleviated.

Description

technical field [0001] The invention relates to a compound microbial fertilizer, in particular to a compound microbial fertilizer suitable for leguminous plants. Background technique [0002] Leguminosae is a family of dicotyledonous plants and Rosaceae, belonging to trees, shrubs, subshrubs or herbs. Legumes have important economic significance and occupy a large proportion of economic crops; the roots of legumes There are often root nodules formed in symbiosis with rhizobia, which have positive significance for plant growth and soil fertility. [0003] Microbial fertilizer refers to a type of fertilizer product that uses the life activities of microorganisms as the core to enable crops to obtain specific fertilizer effects. At present, microorganisms are often used in combination with organic and inorganic substances to achieve the best results. [0004] Chinese Invention Patent Specification CN107337549A discloses a biomass functional fertilizer that enhances leguminous ...

Problems solved by technology

[0004] Chinese invention patent specification CN107337549A discloses a biomass functional fertilizer that enhances leguminous crops-rhizobia mutualism and its application. It improves soil physical and chemical properties through the combination of rhizobia and organic and inorganic nutrients, and artificially improves The number of rhizobia, however, the effect of improving the soil through organic and inorganic nutrients cannot be maintained for a long time, and artificially increasing the number of rhizobia, the rhizobia will soon reach saturation, and the number of bacteria is single, which does not improve the fertilizer efficiency of legumes. obvious
