| Abstract: | Analyzed the key of forestation on deteriorated lands and pointed out that the difficulty is seedling survival, strong of included the seedlings lack, remote of the geographical position, the low of soil moisture availability, the seedling evapotranspiration and the difficulty of seedling root regeneration. The article put forward some countermeasures such as container seedlings with balanced root system, drought-tolerance taming of the seedling in nursery, keep the native vegetation soil preparation, enhance investment in scientific research and change ideas |
