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。

Recent developments in the research on the geology and geochemistry of the newly-discovered clayey breccias at the lop of the Xiaochaka Formation in the Juhuashan, Xiaochaka and Shishuihe areas, Qiangtang Basin, northern Tibet have disclosed that mineral compositions, textures and structures, occurrences and sectional architectures of the clayey breccias agree well with those of the paleo-weathering crust in these areas. Compared with the bedrocks, the paleo-weathering crust is characterized by the leaching out of CaO and CO2, and relative enrichment of SiO2, Al2 O3, Fe2O3, K2O, Na2O, MnO and P2O5. The clayey weathered residues in the paleo-weathering crust are characterized by marked enrichment of REEs, much higher contents of LREEs than those of HREEs, markedly positive Ce anomalies and negative Eu anomalies, and a noticeable increase in other element contents besides Mo, Sn and U from the clayey weathered residues.
