This invention discloses a green and ecological planting method for daylilies, belonging to the field of agricultural planting technology. It addresses the technical problems of excessive reliance on chemical fertilizers and traditional mulching in current daylily cultivation, leading to soil ecological imbalance and low fertilizer utilization. The method includes: applying organic fertilizer made from cow and sheep manure and Asteraceae plant residues through aerobic composting, using a layered strip application method. First, fully decomposed organic fertilizer is applied as a base fertilizer layer in the planting furrow, followed by semi-decomposed organic fertilizer that has completed the main fermentation stage but not the later aging stage as a middle layer fertilizer; after land preparation and ridging, wood ash is spread on the ridge surface, followed by the laying of black fully biodegradable mulch film; finally, holes are made in the mulch film for daylily seedling planting. This method is mainly used for sustainable ecological planting of daylilies, improving soil fertility and structure, regulating soil pH and providing potassium, conserving moisture and suppressing weeds while avoiding residual pollution, thereby increasing daylily yield and quality while reducing environmental impact.

The present application relates to the technical field of sapling cultivation, in particular to a seedling anti-freezing device for forest cultivation, which comprises a base and a water inlet, the base is hollow and has a water storage function, the outer wall of the base is made of rubber plastic material and has a heat preservation effect, at least two heat exchange mechanisms are installed on the upper surface of the base at equal intervals in the circumferential direction, the heat exchange mechanisms extract water from the air to supplement the saplings, a supporting mechanism is installed between the heat exchange mechanisms, the bottom of the supporting mechanism is fixed to the base, the supporting mechanism supports the plastic cloth and prevents the saplings from freezing. The device effectively breaks the low-temperature-induced dormancy mechanism of the sapling root system, prevents the sapling rhizome from freezing injury and death, provides a suitable temperature environment for root development, effectively avoids soil water evaporation, continuously ensures soil moisture, promotes the growth and development of the sapling root system, and thus shortens the tree maturation period. The device can increase the light concentration to increase the temperature and avoid low temperature from inhibiting the growth of the saplings, or can reduce the light concentration to reduce the temperature and prevent high temperature from burning the saplings.

The invention belongs to the technical field of traditional Chinese medicinal material seedling raising, and discloses a method for improving seedling raising uniformity of radix paeoniae rubra in Sichuan, which adopts a covering material with a double-layer film or multi-layer film structure to improve the soil temperature and humidity regulation and control capability. The novel covering film material can comprise a layer of light reflecting film and a layer of light absorbing film, so that heat preservation and moisture preservation can be realized, and the growth of weeds can be controlled. The way of laying may also be further optimized, such as by mechanical laying to ensure uniformity of the covering and durability of the film. An intelligent water and fertilizer management system is introduced, a soil humidity sensor and a nutrient monitoring device are combined, the moisture and nutrient content of field soil is monitored in real time, and the time and dosage of irrigation and fertilization are accurately controlled. In the cultivation management process, application of biological control and green plant protection technologies is added, such as natural control means of natural enemy insects, plant extracts and the like, use of chemical pesticides is reduced, and meanwhile the disease resistance of crops is enhanced.
