Embodiment

[0027] Embodiment: The present invention uses branches and fallen leaves as raw materials, and the branches and fallen leaves are discarded branches or fallen leaves of broad-leaved tree species. Do not choose pines and cypresses with volatile odors. The present embodiment takes poplar branches and fallen leaves as an example, a fungus Root bio-fertilizer and preparation method, comprising the following steps,

[0028] ①Sieve the vermiculite, take the part with a particle size greater than 1mm, and set aside;

[0029] ②Crush poplar branches and fallen leaves, sieve, and take the part with a particle size of 1mm-10mm for subsequent use;

[0030] ③Put the sieved vermiculite and crushed poplar branches into an autoclave to sterilize, cook at 121°C for 2 hours, spread out the materials after cooking, and let them cool in the air;

[0031] ④Mix the cooled vermiculite and crushed poplar branches in a ratio of 1:1-2 by volume, and mix them into MMN liquid culture medium, and the rat...

Abstract

The invention discloses a biofertilizer for mycorrhizae and a preparation method. The preparation method comprises the following steps: (1) sieving vermiculite; (2) grinding branches and fallen leaves, and sieving the powder; (3) sterilizing the sieved vermiculite and the ground branches; (4) proportionally mixing cooled vermiculite with cooled ground branches, and mixing the mixture with an MMN liquid medium; (5) filling the MMN liquid medium into a polyethylene culture bag; (6) inoculating various ectomycorrhizal fungi; (7) carrying out light-tight culture in a greenhouse or an incubator; (8) mixing with biological activated carbon, organic fertilizers, a biological water-retaining agent and bioactive growth promoting components; (9) packaging and storing. Compared with existing biofertilizers, the biofertilizer 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, in particular to a mycorrhizal biological fertilizer and a preparation method thereof. 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 economic, social and ecological significance for maintaining ecological balanc...
