盐碱地造林技术尚林盐碱地造林成活率不高的主要原因是地下水位高、排水不良、含盐量大、土壤结构坚实。因此要想提高成活率，关键在于降低地下水位、控制土壤返盐、降低土壤含盐量、改良土壤理化性质。深栽浅埋就是达到上述目的的方法之一。这种栽植方法能使苗木根系躲过... Salinization Afforestation Techniques Shanglin saline-alkali land afforestation survival rate is not high mainly due to high groundwater levels, poor drainage, salt content, soil structure is solid. Therefore, in order to improve the survival rate, the key is to reduce the water table, control the soil back to salt, reduce soil salt content, improve soil physical and chemical properties. Deep planted shallow buried is one of the ways to achieve the above purpose. This planting method can make seedling roots escaped ...
