苗木根系蘸磷肥栽植成活率高。这是因为磷素是植物细胞核的重要组成部分,又是细胞分裂,特别是分生组织发育不可缺少的物质。栽植时用磷肥溶液浸根或蘸根,能促使新根增多,生长快,扩大根系吸收营养物质的范围,从而育效地增强苗木的抗寒、抗旱能力,增强对水分的吸收和蒸腾作用,使树苗迅速恢复生机。因此,成活率高,一般
Phytophthora dip Phosphate fertilizer planting high survival rate. This is because phosphorus is an important part of the plant cell nucleus and is also an essential substance for cell division, especially meristem development. Phosphate solution when planting root dip or dipping root, can promote new root increased, rapid growth, expand the root absorption of nutrients within the scope, so as to effectively enhance the seedlings of cold, drought resistance and enhance water absorption and transpiration, Saplings quickly restored vitality. Therefore, the high survival rate, in general
