The invention belongs to the technical field of microorganisms, and discloses an amorphophallus bulbifer southern blight infection influence analysis method based on metabonomics and microbiomics. Conjoint analysis shows that core florae (such as Streptomyces, Penicillium and Bauldia) are in significant positive correlation with phenylpropanoids and glutathione (succinic acid, coniferyl alcohol and glutamic acid), succinic acid is in positive correlation with Kribbella and Terrimonas, 2 ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', 2' ', the 3, 3 '-cycle CMP is negatively correlated with pathogen-related bacteria, which indicates that the metabolite regulates and controls the abundance of specific bacteria through positive / negative feedback so as to drive the microecological balance of rhizosphere, and a collaborative defense strategy that plants recruit beneficial microorganisms and inhibit pathogenic bacteria through metabolism reprogramming is disclosed.

The invention belongs to the technical field of amorphophallus bulbifer cultivation, and discloses an amorphophallus bulbifer deep ditch soil moisture conservation cultivation method capable of promoting early sowing and stable yield, which comprises the following steps: selecting a land with high fertility and good fertilizer and water conditions; reasonable close planting is conducted, the seed balls of the amorphophallus bulbifer range from 150 g to 200 g, the line spacing is 90 cm, the plant spacing is 35-40 cm, and in other words, 3200-3500 plants are planted per mu; planting amorphophallus bulbifer corms in the middle positions in the ditches, covering the amorphophallus bulbifer corms with soil with the thickness of 5cm, and laying straw to maintain humidity and provide a suitable growth environment. The amorphophallus bulbifer deep-ditch soil moisture conservation cultivation method for promoting early sowing and stable yield is used for promoting early sowing of the amorphophallus bulbifer, resisting drought and keeping the stability of the soil moisture content, later-stage ridging and farming operation are facilitated, the amorphophallus bulbifer can be sown 30 days earlier, and seedlings emerge 15 days earlier. Through the steps, the yield and quality of the ginger can be effectively improved. Compared with a traditional pond hole digging planting mode, the yield can be increased by 15%-20%.

This invention belongs to the field of plant rhizosphere research and discloses a method for determining the regulatory effect of exogenous selenium application on the rhizosphere microecology of Amorphophallus bulbifera. The method includes: experimental design and sample collection; soil microbial DNA extraction and amplicon sequencing; and quality control and analysis of the microbiome data. This invention utilizes Illumina MiSeq high-throughput sequencing technology to analyze the changes in the composition and diversity of rhizosphere soil bacteria communities in Amorphophallus bulbifera under exogenous selenium treatment, and further analyzes the functions of related communities through PICRUSt functional prediction analysis. The conclusions are as follows: exogenous selenium treatment induces significant changes in the rhizosphere soil bacterial community of Amorphophallus bulbifera, which is beneficial for creating a stable and more diverse rhizosphere microbial community structure.
