The present application belongs to the field of under-forest planting, and particularly relates to a method for improving cold resistance and yield of Cistanche tubulata under Chinese tamarix forest in the Yellow River Delta region. The method improves host root activity and resistance through root system root cutting treatment and spraying treatment liquid; promotes Cistanche tubulata inoculation resistance and survival rate through gibberellin seed dressing, three-layer seeding and spraying Hoagland nutrient solution; enriches soil nutrition, improves soil heat preservation performance, and improves the cold resistance and yield of Cistanche tubulata through near-natural substrate seed dressing, soil microbial fertilizer, farmyard manure and post-covering treatment and other measures. For Cistanche tubulata broken in the fall and winter, the cold resistance is increased by spraying exogenous calcium. The above measures increase the soil temperature by 2-4 DEG C, the cold resistance of Cistanche tubulata under Chinese tamarix forest is improved by more than 63%, and the yield is improved by more than 40%, which has important significance for the industrialization and large-scale cultivation of Cistanche tubulata under Chinese tamarix forest in the Yellow River Delta region.

The present application relates to the field of ecological restoration of coastal salt marsh wetlands, and specifically discloses a recovery mode for high-tide beach areas based on a variety of salt marsh vegetation communities, comprising: selecting or artificially constructing a high-tide beach habitat suitable for salt marsh vegetation recovery; determining the planting location and distribution of the salt marsh vegetation combination according to the habitat conditions; laying out a device for preventing damage by pigs before transplanting; tracking, monitoring and maintaining the growth of the salt marsh vegetation combination after planting to evaluate its survival rate; the present application combines native plants such as reeds, and plants reed canary grass and tamarisk together to enrich the shore plant in a way to form multi-level plant buffer zones such as "grass-grass" and "grass-shrub" to enhance the stability and resilience of the coastline, and at the same time achieve the purpose of improving the carbon sink effect. This configuration and combination recovery mode breaks the previous recovery mode mainly based on a single species, and provides new strategies and modes for native plant replacement after the removal of spartina alterniflora and the development of coastal wetland ecological restoration technology.

The top of the U-shaped supporting plate is provided with a flange, and the top of the flange is provided with a C-shaped slideway; a plurality of nutrition bowls are placed in the U-shaped supporting plate; the connecting plate stretches across the U-shaped supporting plate; the two ends of the connecting plate are in sliding fit with the C-shaped sliding ways on the two sides of the U-shaped supporting plate respectively. A placing hole is formed in the connecting plate; guide columns are arranged at the top of the connecting plate; the pressing plate is in sliding fit with the guide columns; a protruding part is arranged at the bottom of the pressing plate, the pressing plate can press the cutting slips downwards, and the protruding part can eject the cutting slips out of the containing hole; a plurality of nutrition bowls can be moved out of the grooves at the same time by carrying the U-shaped supporting plates, the situation that the nutrition bowls are carried one by one is reduced, and the carrying efficiency can be improved; when a plurality of nutrition bowls are transversely arranged in the groove, the cutting difficulty of the nutrition bowls in the middle of the groove can be reduced.

The invention provides a ThNAC87 gene for regulating and controlling salt gland development of tamarix hispida and application of the ThNAC87 gene, and belongs to the technical field of gene engineering. The nucleotide sequence of the ThNAC87 gene disclosed by the invention is as shown in SEQ ID NO. 3. The ThNAC87 gene is constructed into a plant expression vector, tamarix hispida is transformed, the ThNAC87 gene is over-expressed in tamarix hispida, development of salt glands of tamarix hispida can be promoted, salt efflux is further promoted, phenotype and physiological index observation shows that compared with a non-transgenic plant, the over-expressed transgenic plant is high in resistance enzyme activity, and the resistance enzyme activity of the non-transgenic plant is high. The damage index is obviously lower than that of a non-transgenic plant, so that the salt stress resistance of the plant can be improved by overexpressing the ThNAC87 gene in the plant. The ThNAC87 gene disclosed by the invention has a relatively good application prospect in the field of improving the salt resistance of plants.
