The application provides application of a traditional Chinese medicine composition in preparation of a heart failure resisting medicine. A first aspect of the application provides application of a traditional Chinese medicine composition in preparation of a heart failure resisting medicine, wherein the traditional Chinese medicine composition comprises the following raw materials in parts by mass: 165-185 parts of radix notoginseng, 90-110 parts of radix astragali, 10-30 parts of radix ginseng, and 10-35 parts of pachyrhizus or radix puerariae. According to the pathogenesis of heart failure, i.e. yin deficiency and less body fluid, the traditional Chinese medicine composition can improve dry mouth and throat, and thirst caused by heat, and finally realize the treatment of heart failure through prescription. Animal experiments show that the traditional Chinese medicine composition has a significant anti-heart failure effect, and can obviously improve heart failure of spontaneous hypertension rats, and has a significant curative effect.

The application discloses a salt tolerance evaluation method and system for Radix Eupatroris. The salt tolerance evaluation of Radix Eupatroris is based on a first SVM regression model. The samples used in the process of training the first SVM regression model are different from those of the related art. In the planting plan that aims to improve economic benefits on the premise of environmental benefits, Radix Eupatroris plays a role of "connecting the past and the future". The samples used in training the first SVM regression model in the specification not only involve the benefits that can be achieved by the planting period of Radix Eupatroris, but also take into account the influence of the environmental conditions in the historical period on the planting plan of Radix Eupatroris, and the influence of the planting plan of Radix Eupatroris on the prediction of the next year combined with the prediction of the environment, so as to realize the comprehensive evaluation of whether the salt tolerance of Radix Eupatroris matches the target planting area by taking into account the three time periods of history, current and future.

The invention relates to the field of biological prevention and control, in particular to a biological prevention and control method for spotted wing drosophila based on double-organism temperature control and a research method. The temperature for releasing the Pseudocera pupae is 18 DEG C. At 14 DEG C, no parasitic wasps emerge from the spotted wing drosophila melanogaster; the intrinsic growth rate and the periodontal growth rate of the pupa are obviously lower than those of the spotted wing drosophila at the same temperature; the optimal net parasitism rate, the weekly-limited parasitism rate and the stable parasitism rate of the Pachyrhizus pupae are observed at the temperature of 26 DEG C, but simulation data show that the number of the Pachyrhizus pupae populations can be remarkably reduced under the condition that damage is reduced by releasing a large number of Pachyrhizus pupae at the temperature of 18 DEG C; the high reproductive capacity of the Drosophila melanogaster at 22 DEG C and 26 DEG C obviously reduces the biological control efficiency of the Drosophila melanogaster, which indicates that more than thousands of times of parasitic wasps are needed and the control time is too late; and the long egg laying days and egg laying period at 18 DEG C are beneficial to the biological control efficiency.

The invention belongs to the technical field of plant cultivation, and particularly relates to a preparation method of a pachyrhizus erosus cutting slip for cross-region and / or peak shifting cuttage and a pachyrhizus erosus cuttage seedling raising method.The method comprises the following steps that in the growth environment with the average temperature being 20-25 DEG C and the average humidity being 80%-90%, a pachyrhizus erosus branch with two bud points is selected, the distance between the two bud points is 12-20 cm, and the pachyrhizus erosus branch with two bud points is selected; respectively truncating at positions 4-6cm away from the two bud points to obtain cutting slips containing the two bud points; the morphological lower ends of the cuttings are placed in a water retention carrier containing a bacteriostatic agent, then the cuttings are placed in a water retention appliance, and the pinto bean cuttings are obtained. According to the preparation method, the high vitality of the cuttings after long-distance and long-time transportation can be guaranteed, and the highest cuttage survival rate of pinto beans can reach 95.10%.

The application discloses a preparation method of Pueraria lobata flower polysaccharide and application of the Pueraria lobata flower polysaccharide in anti-glycation and antioxidation, relates to the technical field of traditional Chinese medicine extraction, and is mainly applied to the medical, food and beauty industries. The Pueraria lobata dried flower is crushed into fine powder by using an impact type pulverizer, is sieved, is soaked and stirred for 30 min by using purified water, is adjusted to pH 3-5 by using dilute hydrochloric acid, is enzymolyzed at 40-55 DEG C for 60 min, is then raised to 80 DEG C to inactivate the enzyme, is filtered, the filtrate is collected, is concentrated by using a rotary evaporator, is precipitated by adding ethanol, is placed at 2-8 DEG C overnight, is filtered, the precipitate is collected, the precipitate is washed 2-3 times by using anhydrous ethanol, and is then dried under reduced pressure to obtain the Pueraria lobata flower polysaccharide. The application provides an enzymatic extraction process of Pueraria lobata flower polysaccharide. The Pueraria lobata flower polysaccharide prepared by using the method not only has an inhibiting effect on the generation of advanced glycation end products AGES, but also has a remarkable antioxidation effect.

This invention belongs to the field of traditional Chinese medicine processing technology. It addresses the issues of heat uniformity during the drying process and the loss of components and quality stability caused by differences in different medicinal materials. The invention discloses a process for slicing kudzu root while it is still fresh, comprising the following steps: slicing the kudzu root; adding treated porous ceramic after slicing; mixing evenly; drying; and finally sieving out the porous ceramic after drying. This invention introduces treated porous ceramic into the drying process of kudzu root, which promotes heat uniformity and improves drying efficiency. It also allows the antioxidant effect of guaiac gum to be utilized, and the porous ceramic treated with guaiac gum is easier to separate from the kudzu root. Furthermore, this invention develops a reasonable fresh-cutting process tailored to the differences in different medicinal materials, reducing the loss of active ingredients and changes in appearance while ensuring the quality stability of the processed slices.

The application discloses a kind of based on whole genome high-efficiency cassava tuber centipedal root glycoside content prediction method, belong to plant molecular breeding technical field.The method comprises: obtaining the whole genome SNP data of the measured cassava sample;The whole genome SNP data is substituted into prediction model to predict the measured cassava tuber centipedal root glycoside content.The application breaks through the limitation that traditional method needs to wait for the maturity of cassava to determine, can be predicted in cassava seedling stage, and the model prediction accuracy reaches 66.15%, and the error value between predicted value and measured value is between 1.29% and 14.44%.The method significantly shortens the breeding cycle, reduces field test and phenotypic determination cost, improves breeding efficiency and breeding accuracy, and has important application value in low-toxicity cassava variety breeding and large-scale breeding practice.
