title: Farmland soil treated with silkworm sand for 1.5 years
design: Multiple samples were sequenced in parallel using Illumina NovaSeq 6000, and the sequence in each sample introduced an Index tag sequence indicating the source information of the sample. The data of each sample is distinguished according to the Index sequence, and the extracted data is saved in fastq format, and each sample has two files, fq1 and fq13.
