The special fertilizer is prepared from biogas residue obtained after aerobic fermentation, auxiliary materials and a compound microbial flora, wherein the auxiliary materials comprise potassium fulvate, sodium humate and amino acid powder; the compound microbial flora is formed by lactic acid bacteria, bacillus subtilis and paenibacillus polymyxa; the ratio of the viable count of the lactic acid bacteria to the viable count of the bacillus subtilis to the viable count of the paenibacillus polymyxa is equal to 1.2 to 2.8 to 1;the adding amount of the compound microbial flora accounts for 1.4% of the total mass of the special fertilizer; the total adding amount of the potassium fulvate, the sodium humate and the amino acidpowder accounts for 30% of the total mass of the special fertilizer, and the mass ratio of the potassium fulvate to the sodium humate to the amino acid powder is equal 1 to 1 to 1. The invention alsoprovides a processing method of the special fertilizer for rice-shrimp farming and application of the special fertilizer in rice in the periods of 'breeding shrimp before rice cultivation' and 'breeding shrimp after rice cultivation' in a 'one-rice and three-shrimp' planting mode. The special fertilizer provided by the invention has the advantages of being low in production cost and excellent ineconomic benefit, protecting the ecological environment and the like, and has a great significance for promoting the development of the 'one-rice and three-shrimp' mode.

The invention discloses a set of genes used for bladder cancer detection and application. The set of genes used for bladder cancer detection comprise the following 32 genes: a CA9 gene, a CDK1 gene, aCTSE gene, a DMBT1 gene, an ERBB2 gene, an HOXA13 gene, an IGF2 gene, a CXCR2 gene, an MAGEA3 gene, an MDK gene, an MMP1 gene, an MMP12 gene, a RBP2 gene, a CCL18 gene, an SNAI2 gene, a VEGFA gene, an MFAP5 gene, an SGK2 gene, a WFDC2 gene, a POSTN gene, an NPFFR2 gene, an ANXA10 gene, a CTAG2 gene, a ZDHHC2 gene, a KRT20 gene, a PPP1R14D gene, an FGD3 gene, an AHNAK2 gene, an SEMA3D gene, a ZNF707 gene, a LOC100652931 gene and an LINC00565 gene. High accuracy and objective result interpretation by adopting a detection kit of the set of genes for bladder cancer detection are proven clinically; meanwhile, as non-invasive detection, compared with existing cystoscopy, the detection kit has the advantage that the compliance of a patient is greatly improved, and the detection kit has importantclinical significance to early detection and postoperation monitoring of bladder cancer.
