This invention discloses a method for promoting somatic embryogenesis and maturation in Cryptomeria japonica, belonging to the field of somatic embryogenesis technology. The method involves using immature seed embryos as explants to induce embryogenic callus; transferring the proliferated embryogenic callus to a somatic embryogenesis induction medium for further culture to obtain somatic embryos; transferring the somatic embryos to a somatic embryogenesis maturation medium for dark culture to obtain mature cotyledonary embryos; transferring the mature cotyledonary embryos to a somatic embryogenesis basal medium for light culture to obtain somatic embryonic seedlings; and hardening off the seedlings before transplanting to obtain regenerated plants. The results of this application show that embryogenic callus can be stably obtained from different families, with high somatic embryogenesis maturation capacity and rate, enabling the cultivation of a large number of high-quality seedlings with stable genetic traits in a short time; avoiding the phenotypic segregation problem caused by gene recombination during seed propagation, and ensuring that offspring plants inherit the superior characteristics of the parents.

The invention relates to a fish protein-containing organic water-soluble fertilizer and a preparation method thereof, and belongs to the technical field of fertilizers, the fish protein-containing organic water-soluble fertilizer comprises the following raw materials: fish protein hydrolysate, a composite extract, a nitrogen-phosphorus-potassium composite material and a trace element composite material. The fish protein hydrolysate is prepared by performing enzymolysis on deep-sea fish processing leftovers, adding phyllanthus emblica and sophora alopecuroide, and performing co-fermentation; the compound extract comprises a pinus armandii extract, a cryptomeria fortunei extract and a red clover extract. The fish protein-containing organic water-soluble fertilizer prepared by the invention can accelerate the decomposition and conversion of organic matters in fish protein, provides richer available nutrients for crops, fundamentally improves the utilization efficiency of the fertilizer, and also can effectively promote the development of root systems and promote the growth of plants.

The utility model discloses a device for improving the germination rate of cryptomeria japonica seeds and raising seedlings, comprising: a germination box, a light-shielding top cover detachably connected to the top end of the germination box; a heat preservation mechanism, the heat preservation mechanism comprising four groups of heat preservation water tanks, the outer wall of the heat preservation water tank being detachably connected with a heat preservation pad; a seedling bed, the seedling bed comprising a water storage tank fixed to the bottom of the germination box, the top of the water storage tank being fixedly connected with a perforated plate, and the top surface of the perforated plate being paved with a sponge; a humidifying mechanism, the humidifying mechanism being arranged on the bottom surface of the light-shielding top cover, the humidifying mechanism and the heat preservation water tank being fixedly communicated through a connecting pipe, and a water pump being installed on the connecting pipe; a temperature and humidity monitoring mechanism, the temperature and humidity monitoring mechanism being electrically connected with a host computer; a visual monitoring assembly, the visual monitoring assembly being installed in the germination box. The utility model connects the heat preservation mechanism and the humidifying mechanism, uses constant-temperature water heating, and the humidifying mechanism directly extracts the water of the heat preservation water tank for atomization, so as to avoid the influence of water mist on the temperature in the germination box.

The application provides a composition with oil control and acne removal, barrier repair effects and application thereof, and belongs to the field of cosmetics.The composition is composed of Sabina vulgaris leaf extract, Hibiscus sabdariffa flower extract, paeonol and Cryptomeria fortunei bud extract.The Sabina vulgaris leaf extract has the effects of balancing oil secretion and shrinking pores;the Hibiscus sabdariffa flower extract is rich in organic acids and anthocyanins, has the effects of dissolving pore plugs, controlling oil, resisting inflammation, smoothing acne skin and has the effects of moisturizing and removing redness;the paeonol has natural antiseptic effects on gram-positive bacteria and part of gram-negative bacteria, has the effects of acne removal, sterilization, inflammation reduction and whitening;the Cryptomeria fortunei bud extract can promote skin tissue structure regeneration and strengthen skin barrier.The composition effectively regulates excessive secretion of sebaceous gland oil and acne skin specific proteins through the synergistic effect of various components, promotes the health of acne skin, simultaneously repairs the skin barrier and enhances the self-protection ability of the skin.
