T/AEAICC 002-2021 Wetland Pine Resin-based Composite Target Efficient Management Technical Regulations

Scope

Main technical content: For mixed-use forests of wetland pine resin, the site index requirement is above 12~14; for wetland pine resin mixed-use forests cultivating large-diameter timber, the site index should be above 16; the density of 20-year-old stands should be controlled at 450~750 trees/hectare, with the removal of dead and weak trees, and the cleaning of surface residual pine resin and garbage. From early June to August, weeds and shrubs in the forest should be cut and spread evenly on the surface. Protect the litter of understory vegetation, especially broadleaf vegetation. It is best to use organic fertilizer. For inorganic fertilizer application, nitrogen and phosphorus fertilizer can be mixed, and potassium fertilizer should be added in appropriate amounts. Composite fertilizer (with a nitrogen content of 46%) should be used with a fertilizer application rate of 50 kg/hectare/year. Apply 200~250 g/tree of superphosphate and fertilize using an annular trench with a depth of 60cm×15cm×20cm. Retain and protect the understory broadleaf vegetation or precious tree species and regeneration seedlings. Manage artificial forests using a near-natural management model to build a forest ecosystem with complex stand structure, rich and stable biodiversity, and a reasonable extension of the rotation period, paying attention to the natural compensation of nutrients and avoiding excessive loss of soil nutrients. Strengthen forest fire prevention and pest control, establish a long-term monitoring mechanism, and determine soil fertility indicators such as soil organic matter, total nitrogen, ammonium nitrogen, nitrate nitrogen, total phosphorus, and effective phosphorus.
