This invention discloses a cultivation substrate for promoting the growth of Acanthopanax senticosus seedlings and its application, belonging to the field of plant cultivation technology. The cultivation substrate for promoting the growth of Acanthopanax senticosus seedlings provided by this invention uses perlite and peat as a framework to construct a loose, breathable, water-retaining, and fertilizer-retaining physical structure. By adding Bacillus proteolyticus bacterial solution, its growth-promoting, antagonistic, and organic matter-decomposing effects are utilized to improve the rhizosphere microecology. Combined with controlled-release fertilizer, precise nutrient supply is achieved. These three elements synergistically optimize the water, fertilizer, air, and heat environment and microbial community in the rhizosphere of Acanthopanax senticosus seedlings, promoting nutrient absorption and metabolism, effectively improving photosynthetic efficiency and antioxidant enzyme (SOD, POD) activity; and significantly promoting the accumulation of medicinal components. The yield of eleutheroside E in the roots can reach 13.93 times that of the control group, and the yield of syringin in the leaves can reach 2279.82 μg, providing an efficient solution for cultivating high-quality, robust seedlings.

The invention relates to the technical field of edible mushrooms, in particular to a lepista nuda new strain and a cultivation method and application thereof, and the lepista nuda ZDX-1 is obtained by collecting wild resources in Qingcheng County in Qingyang City of Gansu Province, domesticating and cultivating the wild resources and then systematically screening the wild resources. The diameter of pileus is 3-6 cm, the pileus is hemispherical in the early stage, gradually flattened after maturing, smooth in surface, free of flakes, dark purple brown, uniform in color and luster, and not prone to fading. The pleats grow straightly to be bent and are densely arranged, and the color is gradually changed into taupe from light purple. The stipe is cylindrical, upright or slightly bent, the length is 6-10cm, the thickness is 0.8-2cm, the base part is slightly expanded, the color of the stipe is similar to that of a pileus, and the stipe is solid inside and compact in meat quality. According to hyphae of the ZDX-1, bacterial colonies are round, the edges are neat, aerial hyphae are developed, thick and strong, white to light purple and extend towards the periphery in a radial mode, and the hyphae grow compactly. The growth vigor of the culture medium taking glucose as a carbon source and the culture medium taking peptone as a nitrogen source is good on the culture medium with the pH value of 7; the hyphae are observed under microscopic conditions, and the hyphae are relatively dense, have a lock-like joint phenomenon, are not isolated, have coiled conidiophores, can generate a large number of spores, and can be applied to various fields of food preparation.

The invention relates to the technical field of sterile propagation of forest trees, in particular to a method for obtaining syringa oblata aseptic seedlings, which comprises a syringa oblata seed disinfection method and a syringa oblata aseptic seedling cultivation method. The method comprises the following steps: performing soaking and flushing pretreatment on lilac seeds by using tap water, then sequentially disinfecting by using 75% alcohol and a sodium hypochlorite solution with a specific concentration, and inoculating the disinfected seeds to a seed germination culture medium; and after the seeds germinate to form seedlings, further carrying out subculture to finally obtain sterile tissue culture seedlings. The method has the advantages of being high in seed germination rate, high in seedling propagation rate and the like, an effective technical approach is provided for propagation and industrialized seedling production of high-quality syringa oblata aseptic seedlings, and an important reference basis is provided for large-scale propagation of aseptic seedlings of other oleaceae plants; and a basis is provided for improvement of a lilac genetic transformation system and deep research on a molecular gene level.

The invention belongs to the technical field of under-forest planting, and particularly relates to an ecological cultivation method for intercropping cortex acanthopanacis under a Chinese fir forest, and the method comprises the steps: collecting under-forest long-term ecological factors and growth historical data, constructing an improved GWO optimized LSTM prediction model, predicting the ecological factors and cortex acanthopanacis growth indexes in the future 7 days, comparing the most suitable ecological factor range, and determining the growth index of cortex acanthopanacis. When the difference value exceeds the limit, the under-forest ecological environment is regulated and controlled in real time through cultivation measures such as optimizing the opening degree of the sunshade net through WOA. According to the cultivation method, the growth indexes such as the diameter at breast height and the height of the cedarwood and the root thickness, the root bark thickness and the syringin content of the cortex acanthopanacis can be remarkably improved, the yield of the cortex acanthopanacis is increased, meanwhile, the land resource utilization rate and the economic benefit per unit area are increased, and an effective technical mode can be provided for under-forest economic development.
