The transparent planting box comprises a box body and supporting rods, the supporting rods are fixedly installed in the box body, a plurality of sets of supporting rods are arranged, a bottom groove is connected to the bottom face of the box body in a sleeved mode, and handle bolts are connected to the surfaces of the two sides of the bottom groove in a penetrating and threaded mode. The root system display box has the advantages that the transparent box body and the transparent supporting rod are adopted, the whole box body is flat, root systems can be fully displayed, a user can conveniently observe the condition of the root systems close to the edge of the box body in the growth process, meanwhile, the user can take down the bottom groove by rotating the handle bolt, and the operation is convenient. After the device and the plants in the box body are soaked in water together and the planting soil is washed away, the whole root system can be completely presented, the transparent supporting rod located in the box body plays a role in supporting and fixing the root system and supporting the root system, the root system is prevented from being folded when no planting soil exists, the growth condition of the root system is further conveniently observed, and the observation efficiency is improved. And the use effect is improved.

The invention discloses an application of pseudomonas paraxanthohuensis in biological nitrogen removal and sewage treatment. The invention belongs to the technical field of biology, and particularly relates to application of pseudomonas paraxanthoceras in biological denitrification and sewage treatment. The pseudomonas paraxanthomonas disclosed by the invention can be applied to the following aspects: (a1) biological nitrogen removal; (a2) preparing a biological denitrification product; (a3) sewage treatment; and (a4) preparing a product for sewage treatment. As a heterotrophic bacterium, the strain 1.15632 disclosed by the invention has the capability of converting ammonia into nitrogen under an aerobic condition, and also has good ammonia nitrogen and total nitrogen removal capability. The pseudomonas paraxanthoceras shows great application potential in the aspects of improving the sewage treatment effect, reducing the cost and energy consumption and the like.

This invention provides a method for cultivating grafted kiwifruit seedlings with two root systems, comprising the following steps: S1, Rootstock acquisition: Select one one-year-old *Actinidia cuspidatum* and one *Actinidia deliciosa* seedling as rootstocks, and prune the main roots of both rootstocks to a length of 10-15 cm, retaining 4-5 cm of stem; S2, Scion acquisition: Select branches of the *Actinidia deliciosa* variety as scions, with a length of 8-12 cm. Seal the upper end with wax or wound healing agent, and smooth the lower end with a flat cut; S3, Grafting: Using bark grafting or cleft grafting, graft the two rootstocks in opposite directions onto the lower end of the same scion, and wrap the grafting area with grafting film to form a grafted kiwifruit seedling. The grafted seedlings cultivated by this invention have two sets of root systems, one for *Actinidia cuspidatum* and one for *Actinidia deliciosa*, thus exhibiting strong resistance to waterlogging, drought, and pests and diseases, and absorbing nutrients comprehensively, resulting in high-quality and high-yield fruit with significant economic benefits.

The application provides an electrolyte and a secondary battery, a battery module, a battery pack and a power utilization device, wherein the electrolyte comprises: a film-forming additive, the film-forming additive contains a nitrate group in a chemical structure. By adding the film-forming additive containing the nitrate group in the chemical structure in the electrolyte, the nitrate group with high reduction reaction activity can participate in the formation of a sodium ion solvation sheath layer, a sodium metal surface is formed to be rich in NaN x O y and Na3N, and an SEI layer with high conductivity and high mechanical strength, reducing or even avoiding the growth of sodium dendrites. At the same time, the nitrate group has the function of adjusting the sodium metal deposition morphology, which can further reduce or even avoid the formation of sodium dendrites.
