The invention relates to the technical field of essential oil centrifugation, in particular to a centrifugal device for preparing dahurian rose fruit essential oil, and solves the problems that during centrifugal extraction of essential oil from dahurian rose fruits in the prior art, multi-stage separation needs to be carried out to obtain high-purity essential oil, the separation process is complex, the cost is relatively high, and the rapid separation effect is inconvenient to realize. Comprising a coarse separation mechanism, an essential oil purification mechanism and a residue separation mechanism are installed on the outer side of the upper end of the coarse separation mechanism, the residue separation mechanism is located over the essential oil purification mechanism, and a transmission adjusting mechanism is installed on the inner side of the essential oil purification mechanism and the inner side of the residue separation mechanism; the essential oil purification mechanism and the residue separation mechanism each comprise a second separation shell. The essential oil is effectively purified and the loss of residual essential oil is reduced by performing secondary centrifugation on the mixed liquid containing the essential oil after primary separation, the essential oil separation quality is improved, the separation process is shortened and simplified, and the separation cost is reduced.

The invention discloses curculigo orchioides tea and a preparation method thereof. The curculigo orchioides tea is prepared from the following raw materials in parts by weight: 10-30 parts of palmarosa ancient tree black tea, 5-15 parts of curculigo orchioides, 3-9 parts of tassel, 3-9 parts of pseudo-ginseng, 2-6 parts of rosa davurica and 6-12 parts of herba epimedii. The innovative point of the application lies in that an innovative rhizoma curculiginis tea formula is provided by combining a plurality of natural raw materials in a specific proportion, and aims to overcome the defect of single form of the existing product and realize the portability, taste optimization and function diversification of the product, so that the diversified requirements of consumers on natural health drinks are met. Compared with the prior art, the curculigo orchioides tea has the advantages that the curculigo orchioides tea is optimally balanced in the aspects of health care function, taste and portability through mutual matching of accurate weight part proportions, so that the curculigo orchioides tea is easily prepared into standardized tea bags, is convenient to carry and is brewed at any time, and the problems that the existing product is inconvenient to carry and poor in taste are effectively solved.

This invention discloses the application of the RlETC2 gene of Rosa laevigata in inhibiting the formation of epidermal hairs in plants. Addressing the technical challenge of harvesting and processing Rosa laevigata due to the presence of thorns and bristles on the stems, leaves, and fruits, this invention constructs the coding sequence of the RlETC2 gene into the vector pBI121, transforming it into Arabidopsis thaliana to obtain overexpressing plants. Phenotypic verification shows that the transgenic plants have significantly fewer above-ground epidermal hairs on leaves and stems than the wild type, and significantly reduced root hair length. Furthermore, the expression of endogenous epidermal hair negative regulators AtCPC, AtTRY, and AtETC1 is upregulated, while the expression of positive regulators AtGL1, AtGL3, and AtTTG1 is downregulated. In addition, this gene can enhance the scavenging capacity of reactive oxygen species in plant cells under drought and / or salt stress conditions while inhibiting epidermal hair formation, significantly improving the seed germination rate, taproot length, and plant survival rate of transgenic plants under adverse conditions.
