The invention relates to the technical field of plant seed storage, and discloses a method for storing Magnoliaceae seeds. The method comprises the following steps: selecting an open earthen jar with the height of 50-80cm and without holes in the side wall; impurities in the new river sand with the particle size of 0.5-1 mm are screened out, and the new river sand is adjusted to be slightly wet and the surface of the new river sand is white; magnoliaceae seeds and sand are laid in a layered mode according to the volume ratio of 1: (5-10), 5-15 layers are formed, and the uppermost sand layer is 5-8 cm; the sand is placed in a shady, cool and ventilated indoor environment with the temperature of 0-28 DEG C, 5-10 mL / 100 cm of mist is sprayed to supplement water when the sand is dry, and the sand is kept in the state that the sand is slightly moist and the surface of the sand is white; low temperature, disinfection and any chemical agent are not needed in the whole process. The germination rate is stabilized at about 85% after 3-7 months. According to the method, electric energy is not needed, labor is reduced by 50%, the cost is only 1 / 5-1 / 3 of that of traditional low-temperature wet sand storage, materials can be recycled, ecological safety is achieved, operation is extremely easy, and the method is suitable for large-scale safe storage of Magnoliaceae seeds in south-north multi-climate areas.

The invention belongs to the technical field of plant cultivation methods, and particularly discloses a cultivation method for clustered container seedlings of Magnoliaceae plants, which comprises the following steps: selecting a natural plant type dwarf Magnoliaceae plant cultivated variety or stock seed for cutting seedling: from June to July, taking robust current-year twigs without plant diseases and insect pests, processing the twigs into cuttings, and cutting the cuttings into seedlings; soaking the seedlings in a bactericide solution, then quickly dipping the seedlings in a rooting agent solution, spraying water immediately for field planting after cuttage is implemented, and obtaining cutting seedlings after cultivation; root system treatment: after 60-70 days, taking out the obtained cutting seedlings with roots, selecting a plurality of seedlings with vigorous root systems, crossing the root systems, wrapping with a wrapping substrate, pinching, and then placing in a seedling culture bag to form clustered seedlings; planting the obtained clustered seedlings in a tree planting bag, placing the tree planting bag in a container seedling area, performing shading treatment, and then recovering normal illumination for cultivation; after potting and field planting, container seedlings are outplanted.

The invention relates to an application of illicium henryi or an extract of the illicium henryi in preparation of a medicine for resisting porcine epidemic diarrhea viruses. The illicium henryi is a Magnoliaceae plant, namely, Illicium lanceolatum A.C.Smith. The invention further relates to a preparation method of the illicium henryi and the extract of the illicium henryi. Researches show that the illicium henryi extract can effectively and directly kill viruses, block the viruses from entering cells, inhibit the viruses from being copied in the cells and play a role in resisting the porcine epidemic diarrhea viruses, and can be applied to preparation of the medicine for resisting the porcine epidemic diarrhea viruses.
