The present application belongs to the technical field of tobacco planting, and provides a whole-cycle planting method for improving quality and increasing yield of tobacco, comprising the following steps: (1) seed treatment: after cleaning the seeds with water, the seeds are soaked in an elicitor composed of gibberellin with a concentration of 50-1000 mg / L and 10-15 mL / L of Bacillus polymyxa dgnkzx004 fungicide fermentation liquor, then subjected to light treatment, and washed and dried; (2) seedling raising: mixed bacteria cow manure fermentation products are added to the seedling raising substrate, and Bacillus polymyxa dgnkzx004 fermentation liquor is applied for seedling raising; (3) transplanting: the tobacco seedlings are transplanted, and the mixed bacteria cow manure fermentation products are used as fertilizer for fertilization. The present application promotes seed germination rate, improves seedling emergence rate and seedling survival rate, and can significantly improve the growth potential of tobacco root system and the yield of tobacco, and significantly reduce the arsenic content in tobacco leaves.

This invention relates to the field of daylily cultivation technology, specifically to a method for cultivating daylilies resistant to leaf rust. The invention provides a method for cultivating daylilies resistant to leaf rust, comprising the following steps: Seed treatment: After sterilization, daylily seeds are soaked in a seed treatment agent and then placed at a constant temperature of 35-37℃ for 6-8 days to obtain germinated daylily seeds; Seedling management: The germinated daylily seeds are sown in a seedling substrate and cultivated until germination, obtaining daylily seedlings; Transplanting: The daylily seedlings are transplanted into soil treated with a soil treatment agent. This invention's cultivation method can improve the resistance of daylilies to leaf rust.

The invention provides a method for improving the survival rate of apple orchard building in a gravel gobi area, and belongs to the technical field of fruit tree cultivation. The method comprises the following steps: digging a planting trench, and backfilling a substrate material and sandy loam to form an improved planting trench; planting nursery stocks in the improved planting furrows, fixing trunks, sleeving the nursery stocks with moisturizing bags, and removing the moisturizing bags when sprouts grow to 2-3 cm; the substrate material comprises at least one of cotton straw, weed branches and miscellaneous manure; the total salt content of the sandy loam is less than 3.5 g / kg, and the pH value of the sandy loam is less than 8.5; the stock variety of the nursery stock is Qingzhou stock No.1, and the scion variety comprises any one of Qinbrin, Rayleigh and Vinus gold. The problems that gravel gobi soil is barren, water and fertilizer are prone to loss and the stress resistance of the seedlings is poor are effectively solved by improving the soil of the planting area, matching stress-resistant stock-scion combination and matching management and protection measures, the planting survival rate of the apple seedlings and the growth vigor of trees are greatly increased, and efficient orchard building of forest fruits in the gobi area is achieved.

The invention belongs to the technical field of microorganisms, and particularly relates to a bacterium capable of improving quality components of fresh tea leaves and promoting rooting of tea trees, a fungicide and application of the bacterium and the fungicide. The bacterium is lysinibacillus fusiformis Q23 and is preserved in the China Center for Type Culture Collection, the preservation address is No. 299 on eight road, Wuchang District, Wuhan City, Hubei Province, the preservation date is December 19, 2025, and the preservation number of the bacterium is CCTCC NO: M 20252971. The bacterium has the effects of promoting synthesis of biochemical components such as free amino acid and soluble sugar of fresh tea leaves, promoting rooting of tea trees and the like. The strain is easy to culture, can rapidly propagate, is green, organic and pollution-free, and can be widely applied to preparation of plant growth-promoting bacteria.

The invention belongs to the technical field of tobacco planting. The invention provides a complete-cycle planting method for improving quality and increasing yield of tobacco, which comprises the following steps: (1) seed treatment: cleaning seeds with water, soaking the seeds in an initiator consisting of gibberellin with the concentration of 50-1000mg / L and paenibacillus polymyxa dgnkzx004 degerming fermentation liquor with the concentration of 10-15mL / L, then carrying out light treatment, cleaning and airing; (2) seedling raising: adding a mixed bacterium cow dung fermentation product into a seedling raising substrate, and applying paenibacillus polymyxa dgnkzx004 fermentation liquor for seedling raising; (3) transplanting: transplanting the tobacco seedlings, and applying fertilizer by using the mixed bacterium cow dung fermentation product as fertilizer. According to the method, the seed germination rate is increased, the emergence rate and the seedling rate are increased, the tobacco root growth vigor and the tobacco yield can be remarkably improved, and the arsenic content in the tobacco leaves is remarkably reduced.

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.
