The invention discloses a bifunctional adsorbent of N-TiO2 silkworm-excrement porous carbon and a preparation method of the bifunctional adsorbent of the N-TiO2 silkworm-excrement porous carbon. The preparation method comprises the following steps: (1) firstly mixing and putting silkworm excrement and ZnCl2 in a high-temperature tube furnace, introducing a protective gas to purge, then heating to 300 to 700 DEG C to obtain silkworm-excrement porous carbon (SPC) through reaction; (2) adding butyl titanate to a selective alcohol solvent, drop by drop adding to an aqueous suspension containing the silkworm-excrement porous carbon, enabling the butyl titanate hydrolyzed to generate amorphous TiO2, thus obtaining an A-TiO2/silkworm-excrement porous carbon material; (3) carrying out surface modification on the material through a plasma radiation way to obtain an N doped A-TiO2 silkworm-excrement porous carbon material; (4) calcining the material at the temperature of 180 to 500 DEG C, finally obtaining an N-TiO2/SPC bifunctional adsorption material. The bifunctional adsorption material disclosed by the invention is applied to synchronous adsorption and catalytic degradation of VOCs of aldehydes and benzene series.

The invention discloses pine wood nematode-killing Bacillus cereus, which is classified and named as Bacillus cereus NJSZ-13, and preserved in China type culture collection center, the preservation number is CCTCCM2016660, the preservation date is November 20, 2016, and the preservation address is Wuhan University in Wuhan in China. The Bacillus cereus NJSZ-13 isolated from bodies of pine trees has better competitive ability and colonization ability, and sterile fermentation broth and bacteria aqueous suspension of the Bacillus cereus NJSZ-13 both have strong nematicidal activity on pine wood nematodes. By experiments, 36h after the treatment, the killing rate of the sterile fermentation broth on the pine wood nematodes can reach 100%, bodies of the pine wood nematodes can be digested, 48h after the treatment, the killing rate of the bacteria aqueous suspension on the pine wood nematodes can reach 86.5%, and the pine wood nematode-killing Bacillus cereus has good practicability.
