The invention discloses a preparation technology of yak manure and plant fiber composite Tibetan paper, and relates to the technical field of composite Tibetan paper preparation, and the preparation technology comprises the following steps: screening dried yak manure, removing pebbles and hair impurities, soaking in clear water, and scrubbing to obtain a yak manure material; the yak manure material is placed in a high-temperature steam environment of 100 DEG C or above for continuous sterilization for 30 min, and then mechanical crushing treatment is performed to obtain short-fiber-shaped yak manure crude fiber pulp; the method comprises the following steps: cleaning radix euphorbiae lantu roots and / or branches and barks of daphne odora, and extracting plant long fibers by adopting a mode of combining soaking, beating and tearing, or cooking and treating the radix euphorbiae lantu roots or the branches and barks of daphne odora by adopting a mild alkaline method to obtain traditional plant long fiber pulp; the short-fiber-shaped yak manure crude fiber pulp and the traditional plant long fiber pulp are put into a pulp mixing pool according to the mass ratio of 40%-60%: 30%-50%, the mass ratio of the yak manure crude fiber pulp is preferably 70%-90%, and the aim that the raw materials basically come from the Qinghai-Tibet Plateau is achieved.

The invention relates to the technical field of food processing, in particular to a functional food composition for improving sleep and a preparation method thereof.The composition is mainly formed by mixing plant extracts with homology of medicine and food, soluble dietary fibers and a small amount of flavoring agent, and the plant extracts account for 30%-70%, the soluble dietary fibers account for 30%-70% and the flavoring agent accounts for 30%-70%. And 0-3% of a flavoring agent. The plant extract comprises 10-40% of a lily water extract; 10-40% of an aqueous extract of Herba Aristolochiae; 5-30% of a rose aqueous extract; and 20-60% of a water extract of daphne odora. The soluble dietary fiber is selected from one or more of pectin, algin, konjak and inulin. The natural and safe functional food is prepared by taking the lily aqueous extract, the carex decora aqueous extract, the rose aqueous extract, the aronia castanea aqueous extract, the algin, the pectin and the like as raw materials through the process steps of mixing, granulating, packaging and the like, and can regulate intestinal flora, regulate immune functions and improve sleep.

The preparation method disclosed by the invention is simple and easy to implement, relatively good in reproducibility and relatively high in purity.

This invention relates to the field of plant biotechnology, specifically a two-stage tissue culture regeneration method for Daphne odora based on sugar source regulation. This invention constructs a two-stage tissue culture regeneration system for Daphne odora using both sugar-containing and sugar-free methods. Through six coordinated steps—explant pretreatment, stepwise disinfection, callus induction, adventitious bud differentiation, sugar-free rooting enhancement, and hardening-off transplanting—it solves the technical problems of low germination rate in traditional Daphne odora propagation and poor survival rate after conventional tissue culture transplanting. It achieves stable induction, differentiation, and transplant survival of Daphne odora tissue culture seedlings, shortens the tissue culture propagation cycle, and ensures proper preservation of Daphne odora germplasm resources. This provides stable and feasible technical support for large-scale seedling production, germplasm resource protection, and the industrialized production of Daphne odora medicinal materials.

The invention discloses a tissue culture breeding method for stem tips of passiflora edulis. According to the method, the 6-BA and BEB ganoderan are added into the stem tip axillary bud induction culture medium, so that the axillary buds of the passiflora edulis explant can rapidly germinate, and the germination rate reaches 81% or above. The concentration of ferric salt and the concentration of organic matter in a common MS culture medium are halved respectively, meanwhile, the concentration of microelements is increased by one time, an improved MS culture medium is prepared, then 6-BA and BEB ganoderan are added, and then one-step completion of rapid bud proliferation and seedling elongation is achieved; single buds are cut and inoculated into a rooting induction culture medium, and root systems are gradually formed after 12 days of induction. And after being cultured for 110 days, the seedlings still keep good growth vigor. According to the rapid propagation technology, tissue culture rooting seedlings can be obtained only through three culture stages, the period of a passiflora edulis regeneration system is effectively shortened, and technical support is provided for storing and producing a large number of passiflora edulis seedlings in a short time.
