The invention discloses temperature response type high-temperature-resistant release paper and a preparation method thereof. The release paper comprises a first release layer, a resin isolation layer, a base material layer, a resin punching layer, a temperature-sensitive layer and a second release layer which are sequentially stacked. The PNIPAAm temperature-sensitive layer is additionally arranged on the outer side of the perforated resin isolation layer, when the temperature-sensitive layer is lower than LCST (lowest critical compatibility temperature), molecular chains of the PNIPAAm temperature-sensitive layer are in a stretched state and are large in size, the perforated holes can be blocked, and water circulation can be prevented, when the temperature is higher than LCST, the molecular chains of PNIPAAm are in a contracted state and are small in size, and the perforated holes can be blocked by the PNIPAAm temperature-sensitive layer. Moisture can freely enter and exit through the exhaust holes, so that the use of the release paper is not influenced, and higher temperature can be resisted; the method can solve the problem that the water content of the paper is greatly changed due to the fact that the perforated release paper is influenced by external humidity.

A special cultivation device for selenium-enriched sprouts, belonging to the technical field of soilless cultivation devices, addresses the problems of excessive roots extending beyond the basket during hydroponics, which can easily disperse nutrients and impair water circulation, affecting the normal growth of seedlings inside the basket. Furthermore, roots can clog the gaps in the seedling tubes, also hindering seedling growth and development. The invention includes a main frame and a water supply tank fixed in the middle of the main frame's surface. Several sets of hydroponic tubes are equidistantly and parallelly fixed above the main frame. This invention can cut off excessively grown roots extending beyond the seedling basket, keeping the main growing roots inside the basket. This ensures the distribution of nutrients for sprout growth and prevents excessive root growth from obstructing the effective flow of water within the hydroponic tubes. It also prevents outward-extending roots from entangled with the roots of adjacent seedling baskets, thus avoiding damage to the sprouts during subsequent trimming.
