Method for preparing AMF (Arbuscular Mycorrhizal Fungus) capsule fungicide

Abstract

The invention provides a method for preparing AMF (Arbuscular Mycorrhizal Fungus) capsule fungicide. The method is characterized in that sodium alga acid is used as a basic carrier, a mixture is obtained by matching and mixing multiple fillers such as chitosan, gelatin, glycerol, rice, peat, coal cinder and malt sprout in the basic carrier, a fungicide mixture can be obtained by embedding the fungicide in the mixture after the mixture is sterilized, a spherical object can be prepared by dripping the fungicide mixture into calcium chloride solution in a physical extrusion way, and the AMF capsule fungicide can be obtained after the spherical object is solidified and cleaned. According to the method disclosed by the invention, spores, mycorrhiza and hypha of inner glomus intraradices fungus are embedded in the sodium alga acid, a complete infection process can be completed when the spores, the mycorrhiza and the hypha are seeded in unpasteurized soil, and the infection rate can be increased with the prolonging of the infection time. The method disclosed by the invention has the advantages of simpleness, low cost and low toxicity; an embedding material of the AMF capsule fungicide prepared by the invention can be easily decomposed by microorganism, the preservation time is longer, and the AMF capsule fungicide can be simultaneously and directly seeded in a big field.

Description

technical field [0001] The invention belongs to the technical field of capsule inoculum preparation, and in particular relates to a preparation method of arbuscular mycorrhizal fungus capsule inoculum. Background technique [0002] Arbuscular mycorrhizal fungus (Arbuscular mycorrhizalfungus, arbuscular mycorrhizal fungus) is an endophytic mycorrhizal fungus widely present in soil, and it can form a symbiotic system with 80% of the plants on the earth. Studies have shown that arbuscular mycorrhizal fungi can improve water metabolism in plants, improve drought and saline-alkali resistance; enhance plant disease resistance; promote plants' absorption and utilization of various mineral elements, thereby promoting growth and improving quality. Arbuscular mycorrhizal fungi, on the other hand, use carbohydrates provided by the host plant for their growth and reproduction. Arbuscular mycorrhizal fungi are obligate symbiotic fungi and cannot synthesize DNA by themselves. Therefore, ...

Problems solved by technology

Arbuscular mycorrhizal fungi are obligate symbiotic fungi and cannot synthesize DNA by themselves. Therefore, it has not been possible to carry out pure culture and industrial fermentation like exophytic fungi. It can only rely on plant roots to reproduce and grow with them

[0003] Liquid bacterial agents are easy to produce, low in cost, and easy to use, but difficult to transport, which is not conducive to the growth and reproduction of fungi, and the storage time should not be too long

Solid bacterial agent is produced on the basis of liquid bacterial agent by adding appropriate substances and strains. It is simple to make, convenient to transport and store, and the disadvantage is that the bacterial content of the same quality and volume is lower than that of liquid bacterial agent

Powder is an inoculum made by mixing spores into fillers. It is more convenient to store, transport and use, but there are only spores in the inoculum, and poor germination of spores will affect the use effect of the inoculum
