The invention discloses a botanical formula of a gerbera jamesonii thrip repellent and a preparation method thereof, and belongs to the technical field of botanical pesticides. The formula comprises the following components in parts by weight: 30-35 parts of tea saponin, 30-35 parts of cynanchum komarovii, 15-20 parts of rangooncreeper fruit, 5-8 parts of menthol, 3-5 parts of wormwood extract, polyoxyethylene sorbitan monooleate, ethylene glycol, citric acid or sodium hydroxide and the balance of deionized water, and the proportion of each core component in the optimal formula is accurately optimized. The preparation method comprises the steps of raw material pretreatment, ultrasonic-assisted extraction, slow fire decoction and filtration, concentration, compounding and emulsification, canning and storage and the like, and key process parameters are optimized to guarantee the extraction rate of effective components and product stability. Through the synergistic effect of multiple components, the thrip repellent rate reaches 95.3%-97.8%, the thrip repellent has a remarkable repellent effect on trialeurodes vaporariorum and red spiders, the lasting period is prolonged to 14-18 days, and the thrip repellent is suitable for various flowers and planting scenes.

The invention relates to the field of biological control, in particular to an environment response type African giant snail capsule attractive toxicant and a preparation method and application of the environment response type African giant snail capsule attractive toxicant. The capsule attractant comprises a capsule shell and a composition located in the capsule shell, and the composition is prepared from, by mass, 5%-10% of metaldehyde, 50%-65% of attractant, 30%-40% of macromolecule water-absorbent resin, 0.1%-1% of mildew preventive, 0.1%-1% of preservative and 0.1%-1% of coloring agent. The capsule attractant provided by the invention is ingeniously arranged according to the specific life habits of the African snails, and through various exquisite arrangements of a capsule shell, an internal mildew-proof system, SAP water absorption expansion and water locking, the validity period of the attractant can be remarkably delayed, and the pesticide effect can be highly synchronized with the emergence peak of the African snails; the damage to non-target organisms is greatly reduced through optimal setting of the capsule, and the ecological friendliness is outstanding.

The food materials and medicinal materials such as the sweet broomwort herb, the Japanese climbing fern spore and the gerbera are added to enrich the mouthfeel and the new health care effect of the purple sweet potato polished glutinous rice strips, and the purple sweet potato polished glutinous rice strips are delicous and mellow and have the effects of clearing away heat and toxic materials, removing toxicity for detumescence and increasing urine and removing stone.

The application discloses a fabric dyeing method and a dyed fabric, and the fabric dyeing method comprises the following steps: step 1, adding blue side gerbera into water at 20-30 DEG C and stirring uniformly, filtering after soaking to obtain blue side gerbera pigment extract; step 2, diluting the blue side gerbera pigment extract with water to obtain a dye liquor; and step 3, placing pretreated fabric to be dyed in the dye liquor and dyeing at 20-30 DEG C. The fabric dyeing method uses the blue side gerbera pigment extract as a dye, and dyes the fabric at a specific temperature, so that a purple-dyed fabric can be obtained, and the obtained fabric has excellent color development and color fastness. The application enriches the plant dyeing color system and provides a new way for the value-added utilization of characteristic plant resources in alpine regions.

The invention discloses a soil microbial remediation method for continuous cropping obstacles of gerbera jamesonii, and belongs to the technical field of flower cultivation. Comprising the following steps: ploughing soil after cleaning a garden; mixing the compound microbial agent and the decomposed organic fertilizer according to a specific ratio to prepare a biological organic fertilizer; uniformly applying into soil and uniformly mixing; after proper humidity is kept, mulching film covering and greenhouse closing treatment are conducted for 15-25 days; and after film uncovering and ventilation, planting new-stubble gerbera jamesonii. The compound microbial agent comprises functional microorganisms such as bacillus subtilis, bacillus amyloliquefaciens, trichoderma harzianum and pseudomonas fluorescens. According to the method, the problem of continuous cropping obstacles of the gerbera jamesonii is fundamentally solved by reconstructing healthy soil microbial communities, degrading autotoxic substances, inhibiting soil-borne pathogenic bacteria and improving the soil structure, and unlimited continuous planting is achieved.
