This invention relates to a strain of *Verticillium chlamydosporium*, its culture method, and its applications, belonging to the field of microbial technology. The *Verticillium chlamydosporium* Vc-GXWFY-01 was deposited on April 12, 2023, at the China General Microbiological Culture Collection Center (CGMCC), located at No. 3, Courtyard 1, Beichen West Road, Chaoyang District, Beijing, Institute of Microbiology, Chinese Academy of Sciences, with accession number CGMCC NO.40400. This strain has a high spore yield and exhibits significant functions in controlling nematodes in agricultural and forestry crops and promoting crop growth. Its control effect on root-knot nematodes reaches 50-87%, increasing crop yield and significantly improving economic benefits. The solid-state fermentation medium of this invention ensures sufficient organic matter for the strain while also increasing aeration within the medium, greatly enhancing the production of *Verticillium chlamydosporium* and the number of chlamydosporin spores, producing up to 9.4 × 10⁻⁶ spores. 7 ~2.2×10 8 The number of conidia is 2.7 × 10⁶ / g. 9 ~2.9×10 9 per g.

This invention relates to the field of heat exchange cabinet technology, and discloses an underground energy-saving heat exchange cabinet with adjustable ventilation pipe density. The cabinet includes a cabinet body with balance supports on both sides of its outer wall to maintain balance. The interior of the cabinet consists of two independent chambers: an equipment chamber and a heat exchange chamber. Inside the heat exchange chamber is a heat exchange seat, which comprises three independent processing chambers, arranged sequentially from front to back: a phase change chamber, a hot air chamber, and a cold air chamber. By adding and setting an energy-saving exchange mechanism, during operation, this mechanism not only constructs a curved flow channel through baffles and annular channels to slow down airflow velocity and promote sufficient heat exchange between the hot and cold air chambers, thus improving heat exchange efficiency, but it can also utilize phase change energy storage material blocks to recover residual heat from the hot air. This stored latent heat is released to heat the circulating air when temperatures drop sharply at night, preventing equipment malfunctions due to low temperatures.
