Abstract

A method for promoting growth of Datian sugarcanes by using arbuscular mycorrhizal fungal inoculant uses river sands, perlite, loam and peat soil to serve as culture substrates, uses corns as a host plant to breed arbuscular mycorrhizal fungal spores, collects the culture substrates and plant root systems to serve as the arbuscular mycorrhizal fungal inoculant to be applied to production of the Datian sugarcanes after cultivating for 4-5 months. The arbuscular mycorrhizal fungal inoculant produced by the method serves as an inoculum of the Datian sugarcanes, promotes absorption of nutrient and moisture in the soil of the sugarcanes, improves drought resistance of the sugarcanes, and improves production volume by more than 10%.

Description

technical field [0001] The invention relates to a method for promoting the growth of field sugarcane with arbuscular mycorrhizal fungus. Background technique [0002] Arbuscular mycorrhiza (AM) is a mutualistic symbiont formed by Glomeromycota fungi and plant roots. This type of fungus is named for its ability to form a typical arbuscules structure in plant root cells - arbuscular Mycorrhizal fungi (Arbuscular Mycorrhizal Fungi, hereinafter referred to as AM fungi), more than 80% of terrestrial plants (including mosses, ferns, gymnosperms and angiosperms) can form arbuscular mycorrhizae, which is the most common fungus in nature root type. After the symbiosis of AM fungi and plant roots, it can promote the host plant's absorption and utilization of water and soil mineral elements, especially phosphorus, improve the utilization rate of nutrients, regulate the metabolic activities of the host, enhance drought resistance, promote plant growth, and increase crop yield and qual...
