柿树多零星分布,大面积人工栽植的片园较少,多是由于栽植成活率过低所致。为提高造林成活率,山西万荣县林业局贾廷发通过实地调查,并结合柿树生物学特性进行了分析,提出了提高造林成活率的途径。认为影响栽植成活的因素,主要是:发芽迟、生根慢、栽后缓苗期长,由于断根后伤口处的单宁细胞引起氧化,形成不透水隔离层, Persimmon and more sporadic distribution, a large area of ​​artificial planted less, mostly due to planting survival rate is too low. In order to improve the survival rate of afforestation, Jia Rongfa of Shanxi Wanrong County Forestry Bureau analyzed the biological characteristics of persimmon trees through field investigation and put forward ways to improve the survival rate of afforestation. The main factors that affect the survival of the plantation are: late germination, slow rooting, slow seedling after transplanting, due to the root of the wound after the tannin cells caused oxidation, the formation of impermeable barrier,
