Forest land, cultivates cave and plants.After afforestation, continuous 4 years, foster for annual 2 times；Within after afforestation the 12nd year, carry out intermediate cutting and foster.
The selection that step one, healthy near-mature forest divide
Prosthetic leaflet oak near-mature forest selects standing forest on the sunny side, physical features is smooth, fertile soil, draining are good and traffic convenience
Forest land, and tree growth is healthy, the standing forest that is evenly distributed；The described quercus chenii near-mature forest age is 40-55, is pure forest simultaneously
Or the mixture plantation based on quercus chenii.The forest land of described quercus chenii near-mature forest is positioned at middle descending position；Physical features is shallower, slope
Spend≤12 °；Soil is deep, fertile, draining is good；Mountain soil is red soil or red-yellow soil, pH value 4.5-5.0, and surface layer is organic
Matter content >=4.1%, full nitrogen >=0.15%, full phosphorus >=0.13%.
Step 2, the density of crop regulate and control
Interference in December, 2003 intermediate cutting lobule oakery is wooden and withered vertical, wind-falls blowdown and the weak bad wood of growing way, makes woods
Point canopy density control about 0.6, and standing forest per hectare density keeps 650-1000 strain, the wherein strain of dominant tree density 260-350
hm-2, and standing forest combination once mowing, brush are fostered, make dominant tree intermediate cutting discharge from crowded growing space after fostering
Coming, tree crown and tree root progressively occupy previously interference growing space occupied by wood, decrease forest competition, improve light in woods,
Water, heat condition, make reserve more be grown resource, so that dominant tree photosynthesis and vitality are improved,
Add growth and the hip number of oak.Meanwhile, also update growth for quercus chenii population offspring treelet and provide suitably growth
Environment.
Step 3, forest floor are administered
In December, 2003 is below the tree crown of quercus chenii dominant tree and on the steeper hillside of massif of local, takes stone, just
Draw materials, build an irregular horizontal stone barricade, stone walling width about 0.5cm, prevent erosion；Oak woods upward slope woods
Edge offers a wide 50cm, the gutter of deep 45cm；Setting up simple seed collecting operation sidewalk, have a lot of social connections 1m, in order to profit production operation is lived
Dynamic.
Step 4, bole growth equation manage
The management of bole growth equation refers to the forest diameter of a cross-section of a tree trunk 1.3 meters above the ground tending management more than more than the 24cm growth equation period, is to foster
One of technical measures that standing tree big-diameter wood is crucial.
Tending and intermittent cutting of forest
Every 5 years, oak woods is carried out mowing bushing to foster；Caulis Miscanthis floriduli, Indocalanmus tessellatus, bitter bamboo and Pueraria lobata to be grubbed out and takes, with
Anti-demutation is encroached on；Improve Forest habitat, oak of keeping on top growing space reasonable, equally distributed, promote bole growth equation
Amount.
Target wood selects
Healthy, tall and big, trunk logical straight, satisfactory, clear bole height height, tree crown crown type big, eugonic is selected from dominant tree
And it is wooden as target to encroach on the plant of vestige without pest and disease damage and artificial disturbance, and labelling is listed, wherein target wood density >=150
Strain hm-2, the diameter of a cross-section of a tree trunk 1.3 meters above the ground is more than 36 and diameter of a cross-section of a tree trunk 1.3 meters above the ground current annual increment is more than 0.6cm, and is uniformly distributed；
Nutrient management
In by the end of February, 2012, the portion of going up a hill under quercus chenii elite stand tree crown, opens a semicircular shallow ridges, ditch depth 8-10cm,
Wide 20cm, every strain measure Russia Chan A health compound fertilizer (N:P:K=16%:16%:16%) 1kg, after executing, multiple mud, raw for elite stand
Length and solid supplementary nutrient；The plot that soil layer is shallower and barren is suitably increased table soil.
Pest management
Plant in lobule oakery in bole trophophase is often observed, once find that pest and disease damage is prevented in time
Control；Knocking down typhoon and rupture branch, all fell cleaning, branch and leaf are put and are stayed in forest land.
Step 5, seed production management
Solid observation
Phenological Observation over the years and seed collecting practice have shown that: quercus chenii collect seed period typically JIUYUE 25 days to October 31, too early
Seed collecting fruit has part immaturity can reduce percentage of seedgermination；Collect seed too late easily to cause and be blown to four winds and muroid predation.Suitable for this
At the beginning of 9 months to its solid developmental state of quercus chenii elite stand telescopic observation, calculate seed harvest amount, and determine that sowing cloth is arranged
Area and the amount of labour used.
Weeding
Manually mow in early August, 2012 and remove and sprout, it is ensured that collect seed space, ground, beneficially Seed cloth are laid and seed
Results.
Water management
Do not water in woods, not drought resisting, should it is natural, before late June typhoon Growth season, residual in cleaning out a drain
Stay branch and leaf and mudstone block, it is ensured that draining is unimpeded, it is to avoid forest land hydrops, reduce soil erosion.
Sowing cloth is set up
Within 2012, JIUYUE set up sowing cloth, sowing cloth can use sail to October 30 on 29th under lobule oakery elite stand tree crown
Cloth, non-woven fabrics and woven bag.Rear surrounding anchoring wire or stone is set up to be fixed；It is spaced 3 or 4 days, collects once.
The plague of rats manages
Quercus chenii is during Seed Rain, and it mainly preys on rodent is mountain Mus and Sciurus vulgaris.Once find that muroid takes food
Or find to take food residue fragment, need to strengthen manually patrolling；Change sowing cloth, set up and simply drive thing, be strictly on guard against the plague of rats, reduce seed
Quantity is lost.
Seed grading is preserved
At the beginning of 2012 11 months, the fruit of collection is being positioned on the concrete floor that indoor moisture ventilates, is sprinkling water every day 1 time, protecting
Wet；Small-sized seed is removed with iron wire mesh screen；River after on November 5th, 2012 seed or mix together with acorn-cup being hidden in clean, sterilization
In sand, wet sand bed repertory is used to be hidden in plastic box, bottom and the wet husky thick 2cm in upper strata, sowed March in next year.
