This invention relates to the field of deep processing technology of white hyacinth bean, specifically to a method for preparing a compound spleen-strengthening and dampness-removing white hyacinth bean paste. This invention utilizes low-temperature roasting to pretreat a specific ratio of dampness-removing medicinal herbs, including licorice, poria cocos, coix seed, and bitter almond, and prepares a compound decoction rich in dampness-removing components. This decoction is then used as a biological stressor to promote the germination of white hyacinth beans, with its concentration controlled to encourage moderate germination and the production of substances that resist adverse conditions. Simultaneously, leveraging the plant's water absorption capacity during germination, the invention incorporates the dampness-removing components of the compound decoction. Stable solid-state fermentation with pure Rhizopus further enhances the dampness-removing components of the compound white hyacinth bean and fermented soybean. This not only increases the content of major dampness-removing components such as polyphenols, proteins, and polysaccharides in the white hyacinth bean and fermented soybean, but also increases the content of trace dampness-removing substances such as rutin, quercetin, kaempferol, luteolin, and picolinic acid. It also promotes the dissolution of dampness-removing amino acids—alanine and glycine. The dampness-removing compound white hyacinth bean and fermented soybean components are clearly defined, and the content of spleen-strengthening and dampness-removing substances is richer.

The utility model relates to the technical field of feed processing, and discloses a concentrated feed ingredient scattering device which comprises a box body, and a scattering mechanism, a blocking mechanism and a screening mechanism are respectively arranged on the box body. Feed enters the scattering barrel through the feeding hopper, in the entering process, the feed is evenly scattered through the conical flow dividing block, the feed makes more sufficient contact with the scattering component, the motor is started to drive the rotating shaft to rotate, the two rows of scattering cutters and the multiple scattering plates on the rotating shaft cut, impact and stir the feed, and therefore the feed can be scattered more thoroughly. The scattering knife is responsible for chopping large feed particles, so that materials are crushed and scattered under the action of impact force, the scattering plate further stirs and disperses the feed, the contact area of the feed and the scattering component is increased, the scattering effect is improved, it is ensured that the feed is fully scattered, and subsequent batching and processing are facilitated.

The invention provides a wild-imitating cultivation method for cremastra appendiculata, and belongs to the technical field of orchid plant cultivation. The method comprises the specific steps that wood blocks are treated and laid, and water numbness wood blocks are laid on ridge surfaces; seed treatment and sowing, wherein seeds and wet debregeasia edulis wood chips are mixed and then sown; spreading rotted leaves, namely spreading dried beancurd stick leaves after sowing; and field management. Wherein the cremastra appendiculata can be cultivated in a potting or land mode. According to the wild-imitating cultivation method for the cremastra appendiculata provided by the invention, the water numbness wood blocks and the dried beancurd stick leaves are provided to construct the bionic microhabitat, the water numbness wood blocks provide a natural host environment for symbiotic fungi, the dried beancurd stick leaves release rich organic matters after being decomposed and maintain soil humidity, and efficient planting is realized through the construction of the bionic microhabitat without additional associated fungus bags; the cultivation cost is obviously reduced.

The application discloses a method for simultaneously detecting caffeic acid and rosmarinic acid in prunella vulgaris or its glucoside extract and application thereof. The method simultaneously qualitatively identifies the caffeic acid and the rosmarinic acid in the prunella vulgaris or its glucoside extract by using a thin layer chromatography method; the caffeic acid and the rosmarinic acid are directly extracted by using a specific polar solvent extraction method, and then the content of the caffeic acid and the rosmarinic acid in the prunella vulgaris or its glucoside extract is simultaneously determined by using a high performance liquid chromatography method, with the mixed caffeic acid and rosmarinic acid reference substance as a control. The method has the advantages of high accuracy and precision, good stability and repeatability, and overcomes the complicated HPLC gradient elution method required for simultaneously detecting the caffeic acid and the rosmarinic acid in the prunella vulgaris in the past, and improves the accuracy and reproducibility of the determination. The application firstly finds that the content of the caffeic acid component with the glucoside effect in the preparation of the glucoside extract of the prunella vulgaris is significantly improved, and the corresponding prunella vulgaris conversion content is improved by more than one time.

The application belongs to the field of plant culture, and specifically discloses a tobacco sterile seedling cultivation method, which comprises the following steps: placing dry compressed Jiffy-7 substrate blocks into transparent culture boxes, and adding newly prepared 1 / 2 modified LS nutrient solution into the culture boxes; transferring the prepared culture boxes into a transparent plastic incubator and sequentially placing the culture boxes; incompletely closing the cover of the incubator, and opening a circular hole with a diameter of 5-10 cm in the middle of the cover of the incubator, and sticking a filter membrane larger than the diameter of the circular hole on the cover, etc. Through the technical scheme of the application, the sterile tobacco seedling cultivation method is formed, and sterile tobacco seedlings are successfully cultivated, which can provide experimental conditions for revealing the mechanism of the interaction between tobacco and microbial communities in the research on the interaction between tobacco and microbial communities under greenhouse conditions.

This invention discloses a stepwise thermal control method for improving the process and performance of laser additive manufacturing of nickel-based superalloys. It is based on a dual-laser additive manufacturing process, which includes a first laser and a second laser beam. During the printing process, for each printed layer, the first laser beam is first applied at 20 J / mm². 3 -40 J / mm 3 A low-energy-density laser preheats and partially melts the alloy powder layer on the substrate to optimize its adhesion and improve its stability. A second laser beam at 70 J / mm² is then used. 3 -110 J / mm 3 The high unit volume laser energy density completely melts the alloy powder layer; the alloy powder layer uses nickel-based high-temperature alloy powder. Therefore, this invention can suppress the burn-off of key elements (such as Al, Cr, Nb, etc.) in the alloy powder layer during the melting stage, achieving precise control of component composition and improving surface quality and dimensional accuracy.
