Precious phoebe bournei material and landscape seedling integrated cultivation method
PendingCN113597957AAvoid the phenomenon of low utilization rate in the short and medium termIncrease production capacityCultivating equipmentsSoil preparationPhoebe bournei
The invention discloses a precious phoebe bournei material and landscape seedling integrated cultivation method, and particularly relates to the technical field of seedling cultivation. The method comprises the steps of forest land selection, soil preparation and fertilization, and seedling planting and digging. According to the cultivation method, by improving the initial planting density of afforestation of mountain commercial forests, the phenomena that the cost is high, the forest land is short and the medium-term utilization rate is low due to the fact that cultivated land is rented and occupied to cultivate large afforestation seedlings are avoided, the productivity and economic benefits of the forest land are improved, and the input cost is saved; and according to the cultivation method, on the premise that efficient operation of precious phoebe bournei materials is guaranteed, the continuous increasing requirement of the market for large greening seedlings is met, growth is cultivated with short time, coordinated development is achieved, the industrial chain can be extended, and the phoebe bournei industry can be expanded.

Method for improving quality of poles of artificial young phoebe bournei forest with three-step method
ActiveCN113661874ASolve freezing damageImprove survivabilityClimate change adaptationAfforestationShootLeaf fall
The invention discloses a method for improving the quality of poles of an artificial young phoebe bournei forest with a three-step method. The method comprises the following steps: (1) selecting a sheltering valley land with the altitude of less than 400 m, reserving robust and long-life fallen broad-leaf wood with the height of more than 15 m, keeping the canopy density to be 0.2-0.3, and constructing an afforestation land suitable for growing of the young forest by upper-layer shielding; (2) establishing a young forest group establishment period through measures of soil preparation, afforestation, tending, fertilization, pest control and the like; and (3) selecting dominant wood in the closed forest, carrying out management in the pole growth period, such as release cutting and tending and dominant wood cultivation. The growth internal environment of poles is created, the forest land conditions and the forest stand structure are improved, the preservation rate of young forest is increased, the branching rate of main shoots is reduced, the growth of the poles is promoted, the quality of the dominant wood poles is remarkably improved, and the method has a wide application prospect in the creation of precious tree species timber forests and cultivation of large-diameter trees in the north-central region of Zhejiang Province.
