2results about How to "Avoid excessive dehydration" patented technology

This invention discloses a dry heat treatment method for tomato seeds to enhance seed vigor and extend storage life, relating to the field of tomato seed storage technology. The method includes: selecting mature, plump, and undamaged commercial tomato seeds with consistent maturity and maintaining appropriate moisture content; placing the pre-treated seeds in a single layer on a tray and placing it in a dry heat treatment device, performing dry heat treatment sequentially according to a preset program; comparing the germination indicators of dry heat-treated and untreated seeds to determine the effect of the dry heat treatment; and sealing and storing tomato seeds with qualified germination rates. This invention, through precisely controlled stepwise heating and high-temperature constant-temperature sterilization, effectively activates the seed's internal repair enzyme system while inhibiting metabolic processes that lead to seed deterioration, avoiding physical or physiological damage to the seeds caused by high-temperature treatment, and effectively preventing seed coat cracking, radicle burn, or excessive dehydration.

The utility model relates to the technical field of agriculture, and particularly discloses a pepper seed storage device integrating moisture detection and regulation and control functions. Comprising a shell, an inner container, a vacuumizing assembly and a detachable heating cover. The inner container is provided with a storage cavity and is divided into a plurality of independent cavities through layer partition plates, and a seed tray and a temperature and humidity sensor are arranged in each cavity. The vacuumizing assembly is connected with the storage cavity and used for regulating and controlling the humidity; a heating wire is arranged in the heating cover, so that the seeds can be locally heated and dehumidified. The device supports transverse or longitudinal layered layout, and the heating cover can be arranged on the top or on the side to meet different storage requirements. Through real-time monitoring and independent regulation and control, accurate temperature and humidity management is realized, seed mildew or dehydration damage caused by regulation and control lag in a traditional storage mode is avoided, meanwhile, energy consumption is reduced, and the seed storage period is prolonged. The pepper seed storage device is simple in structure, convenient to operate and suitable for long-term efficient storage of pepper seeds.
