Fast expanding propagation method for mycorrhiza fungus strain

Abstract

The invention discloses a fast expanding propagation method for a mycorrhiza fungus strain. The method comprises the steps of matrix preparing, strain inoculating, host sowing, culturing managing as well as harvesting and preserving. Needed materials of the method are common, the operation process is simple, timesaving and laborsaving, the expanding-propagated strain can achieve the effect, which can be achieved in five months by the conventional expanding propagation technology, in just three months, and compared with that of the conventional expanding propagation technology, time of the expanded propagation technology is shortened by two or even thee months; the fast expanding propagation method can be widely applied in the fields of biological control, ecological environment protection and modernized high-tech agriculture while the strain fungus expanding-propagated by the invention can be used for a test.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a method for quickly and efficiently multiplying mycorrhizal fungi by soil beneficial microorganisms. Background technique [0002] At present, the conventional mycorrhizal fungus propagation technology has the following disadvantages: (1) it takes 4-5 months to complete a propagation cycle, which takes a long time; (2) the substrate used for propagation is mainly sandstone, which holds water Poor performance, it needs to be watered every 2-3 days, which is time-consuming and water-consuming; (3) The substrate is easily polluted by bacteria exposed to the air during the propagation process, resulting in a decrease in the purity of the strains and even failure in propagation. Contents of the invention [0003] In order to quickly and efficiently propagate mycorrhizal fungi and meet the needs of experiments and practical use, the invention provides a time-saving, labor-s...
