The proper planting density should be 1 m × 0.3 m and 0.3 m × 0.3 m for land under broadleaf crown and shady droughty land respectively. If the havelock equipment in field was used, seedlings with 15-20 cm for height and 0.30 cm for diameter should be selected for cultivation, with the density and transmittance being 0.3 cm × 0.3 cm and 50% respectively.
林冠下栽植和山垅旱地造林的适宜密度分别为1 m×0.3 m和0.3 m×0.3 m；若利用农田庇荫设施栽培，应选用苗高15~20 cm，地径0.30 cm以上规格的苗木栽植，栽植密度为0.3 m×0.3 m，遮阳透光率在50%左右。

On mountainous sites, grade Ⅰ or Ⅱ stands including land below the crown of the secondary broadleaf forest and the Chinese-fir plantation or east-facing, shady dry land could be considered for the plantation. The transmittance of crown in the areas should be 55%~60%. One-year-old high quality seedlings above 25 cm tall and 0.25 cm in diameter near the ground-level should be used. For high-yield, field cultivation, shading facility should be considered and seedlings of taller than 15 cm and greater than 0.15 cm in diameter near the ground should be applied. The appropriate density and sunlight transmittance ought to be 30 cm×30 cm and 50%, respectively.
结果表明，利用山地种植，选择透光率为55%~60%的Ⅰ、Ⅱ类立地的残次阔叶林和杉木林冠下，或地形隐蔽、东向的山垅旱地，选用苗高25 cm以上、地径0.25 cm以上的1年生优质苗木造林；利用农田进行庇荫设施高产栽培，应选用苗高在15 cm以上、地径0.15 cm以上规格的苗木栽植，适宜栽植密度为30 cm×30 cm，遮阳透光率在50%左右。

Afforestation costs for seedlings with mudding root and bare-root seedlings are approximately equivalent, so do no-woven-cloth container seedlings with balanced root system and plastic container seedlings, and their costs decrease by 30.5%~32.1% compared with that of bare-root seedlings.
结果表明：应用无纺布容器苗、塑料袋容器苗、蘸泥浆苗造林的8个树种的平均成活率较裸根苗造林提高151.9%~522.8%，栽植当年平均新梢生长量提高325.0%~1475.0%；应用平衡根系无纺布容器苗与塑料袋容器苗的造林成本相当，比裸根苗降低30.5%~32.1%，蘸泥浆苗与裸根苗的造林成本基本相当。
