The present application belongs to the technical field of millet planting, and particularly relates to a method for preventing and treating millet white hair disease, comprising the following steps: S1, spraying fungicides to a planting area in January; S2, spraying fungicides to the planting area again in February-March; S3, carrying out high-temperature sterilization on the planting area 10-15 days before millet sowing; S4, sowing millet in the planting area during the sowing period; and S5, spraying fungicides to the leaf surface of millet when the millet grows to the 7-leaf stage. The present application forms a synergistic prevention and treatment method by controlling the time node of fungicide spraying and cooperating with high-temperature sterilization. The prevention and treatment method has a significant prevention effect and strong radical treatment, can eliminate pathogenic bacteria in the soil from the root cause, greatly reduces the incidence of millet white hair disease, and significantly reduces the yield loss of millet.

This invention belongs to the field of plant tissue culture technology, specifically relating to a tissue culture rapid propagation medium and method for rooting *Carex latifolia*. The invention provides a tissue culture rapid propagation medium for rooting *Carex latifolia*, comprising a rooting medium; the rooting medium uses 1 / 2 MS as the basal medium and further includes NAA 0.8 mg·L⁻¹, IBA 1.0 mg·L⁻¹, sucrose 30 g·L⁻¹, and agar 7 g·L⁻¹, with a pH of 5.8-6.0. The invention also provides a method for direct rooting of *Carex latifolia* through tissue culture rapid propagation. Aseptic seedlings of *Carex latifolia* have their outer, weaker leaves removed, and the original root system cut off, retaining 2-3 cm of the above-ground portion. These seedlings are then inoculated into the rooting medium for rooting culture to obtain rooted seedlings. After hardening off the rooted aseptic seedlings, the well-rooted *Carex latifolia* seedlings are transplanted into a substrate to form new, complete plants. The method for rapid propagation of broadleaf sedge by tissue culture provided by this invention has the characteristics of high rooting rate, large average number of roots, well-developed root system, high transplant survival rate, and robust regenerated seedlings.

The invention belongs to the technical field of plant propagation, and discloses a rare Chinese herbaceous peony bud grafting rapid propagation method, which comprises the following steps: (1) rootstock cultivation and selection, (2) planting box treatment, (3) bud grafting knife treatment, (4) bud scion collection and treatment, (5) bud grafting operation process, (6) management after bud grafting, and (7) bud grafting seedling field planting. According to the growth characteristics of the rare Chinese herbaceous peony, Chinese herbaceous peony bud grafting is adopted for rapid propagation, the cultivation method is optimized, and rapid popularization of high-quality varieties is improved. Meanwhile, a stock selection and cultivation method is optimized, local peony seedlings are selected as stocks, affinity is good, stress resistance is high, and a good foundation is provided for bud scion healing and growth; meanwhile, through normative matrix proportion and cultivation management, it is ensured that the stock grows robustly, and the budding survival rate is increased.

The invention discloses a cultivation method of mycorrhizal edible fungus symbiotic seedlings, and relates to the technical field of edible fungus cultivation, and the cultivation method specifically comprises the following steps: S1, culturing symbiotic plant seedlings; s2, mycelium culture of the mycorrhizal edible fungi: S21, mycelium culture; s22, performing purification culture: selecting the hyphae in the step S21, inoculating the hyphae into a new solid culture medium, and performing standing culture at 24-26 DEG C until the hyphae are overgrown; s23, fermentation culture: inoculating the hypha in the step S22 on a liquid fermentation culture medium, and culturing on a constant-temperature shaking table at 25 DEG C to obtain a liquid strain; s3, infection: injecting the liquid strain in the step S23 into the symbiotic seedling composite culture medium in the step S13, placing the symbiotic seedling composite culture medium in an illumination incubator for culture, and regularly supplementing a nutrient solution during culture; and culturing for 60-90 days to form the mycorrhizal edible fungus symbiotic seedling. The method is high in mycorrhiza infection rate, high in symbiotic seedling survival rate and suitable for popularization.

The present application relates to the technical field of plant tissue culture, and provides a tissue culture method for promoting germination of Zingiber zerumbet Smith, wherein Zingiber zerumbet Smith tubers are used as explants, and after being subjected to disinfection treatment, the explants are inoculated into an induction medium, a proliferation medium and a rooting medium in sequence, and then are subjected to acclimatization, seedling raising and transplanting, so that finished Zingiber zerumbet Smith seedlings are obtained. The germination rate, the proliferation coefficient and the rooting rate of the Zingiber zerumbet Smith tubers can be significantly improved by using the culture media which are optimized and adjusted in the technical scheme of the present application. In addition, the reasonable application of foliar fertilizer and fungicide after transplantation in the present application can further improve the growth vigor and the disease resistance of Zingiber zerumbet Smith seedlings, and ensure the survival rate of the seedlings, thereby providing reliable technical support for rapid propagation and large-scale planting of Zingiber zerumbet Smith.

The invention relates to the technical field of forest tree genetic breeding and propagation, and particularly discloses a seedling raising method for improving the grafting survival rate of phoebe bournei. Comprising the following steps: S1, cultivating phoebe bournei cutting seedlings as rootstocks, and keeping the rootstocks in a robust state for later use; s2, semi-lignified branches growing in the current season are collected from the excellent phoebe bournei stock plants to serve as scions; s3, performing disinfection and pretreatment on the scions to prepare scion sections with wedge-shaped notches; s4, cutting off and cutting the stock, and combining the scions treated in the step S3 with the stock to enable cambiums to be aligned; s5, sealing and fixing the grafting joint part by using a binding belt material; s6, performing stage moisturizing and light and temperature regulation and control on the grafted plants. The seedling raising method can be applied to the fields of efficient germplasm resource utilization, artificial forest and landscape forest construction and the like, and has the advantages that the grafting survival rate is high and stable, the interface healing speed is high, the quality is good, and nursery stocks grow robustly and neatly.
