The heilong river dynasty-anhaling forest group called for an annual frost-free period of just over 80 days, with an annual average temperature of around 15°c and extreme weather of 53°c. How can we grow and grow under such conditions
Established in 1985 as a direct medium-sized enterprise, the central nursery of the central forest office of the office of the high forestry authority covers 256 acres, with the production of more than 2 million trees a year. In recent years, the call-for-forest service has been pursuing scientific development, building on the construction of a solid nursery infrastructure and strengthening the supervision of seedlings, and moving out of the path of developing the characteristics of a state-owned guaranteed nursery in the coldest climate。
In order to ensure a high-quality nursery rate, fda began with the construction of an enhanced nursery infrastructure and the creation of an enabling environment, the construction of more than 600 tons of fresh water reservoirs and six greenhouses and daylight huts, the construction of nearly 1,000 additional metres of rock-laying drainage canals, the upgrading of over 900 square metres of light-based workshops, finished stores and wood cellars, and the completion of a drying yard and road hardening of nearly 2,000 square metres。
With regard to the quality control of seedlings, during the delivery of seedlings, the call-for-forest authorities have assigned seedlings management stations to conduct a full follow-up on the trees assigned to them, strictly enforce the “three certificates and one signature” system, implement a tripartite signature of nurseries, construction parties and seedling stations to confirm the quality of the trees, eliminate from the source the incompetent seedlings, poor quality seedlings, multiple seedlings, etc., and ensure that the allocated trees are of adequate quality, sufficient quantity and meet quality standards for high-quality seedlings. Upland forested trees are marked with a single car, the label of the tree must be followed to the afforestation site, the nutrition cup tree is transported using a dedicated transport box, and the storage, watering and shade of the plantation tree is supervised by specialized technicians。
In 2021, the call-for-forest administration introduced light-based container breeding techniques for rare species such as siberian red pine and pine, which produce about 300,000 light-based container seedlings per year. Last year, in the area of the high-hingying mount, the routine forestry agency took the lead in achieving the full self-sufficiency of the authority's forested greened trees, with no naked seedlings, no external seedlings and no long white mountain leaves.
