This invention discloses a slow-release granule formulation of sodium alginate-biochar loaded with thiamethoxam, its preparation method, and its application. The slow-release granule uses biochar as the adsorbent carrier to adsorb thiamethoxam and sodium alginate as the encapsulating material, which is then cross-linked and solidified by dripping calcium chloride solution. The mass ratio of biochar to thiamethoxam is (10~30):1, the mass-to-volume ratio of sodium alginate to water is 1.5~2.0 g:100 mL, and the concentration of the calcium chloride solution is 1.5%~3.0%. The prepared slow-release granule has a cumulative release time of over 90 hours in distilled water, with no obvious burst release phenomenon. Pot experiments show that it maintains a continuous control effect on eggplant thrips for 7 days after application, which is superior to conventional spraying treatment. This invention has a simple preparation process, is environmentally friendly, and has excellent slow-release performance, making it suitable for green control of agricultural pests.

The application relates to the technical field of fertilizing equipment, and discloses a forestry seedling raising fertilizing equipment which comprises a water inlet pipe and a water outlet pipe, a shell is arranged on one side of the water inlet pipe, a connecting block is arranged in the shell, two cavities are respectively formed in the connecting block, one end of the water inlet pipe penetrates through the shell and is communicated with one of the cavities, corrugated pipes are fixedly connected to the side walls of the shell, and through holes communicated with the two corrugated pipes are formed in the cavity inner walls. The application does not operate by water pressure driving the piston, and the wear of the piston does not need to be considered during operation, so that when the device is used, the problem of regular maintenance caused by the wear of the non-wear-resistant parts does not occur, the device is not afraid of containing small impurities in water when being used, so that a filter does not need to be arranged in front of the device, the cost can be reduced, the trouble of regularly cleaning the filter is saved, and the practicability of the device is enhanced.

The invention discloses a residual ammonia water self-circulation ammonia distillation system and a process method thereof, and belongs to the technical field of ammonia water treatment. The residual ammonia water self-circulation ammonia distillation system comprises an ammonia water supply system, a deacidification system, an ammonia distillation circulation system and an ammonia water generation system which are communicated in sequence, the ammonia distillation circulation system is communicated with the ammonia water supply system, and the ammonia water generation system is communicated with the deacidification system. According to the technical scheme, the system is utilized, the technological method of residual ammonia water self-circulation ammonia distillation is achieved, the energy-saving efficiency is improved, the production cost is reduced, and recycling of ammonia is achieved.
