1985～1987年进行的试验表明,在山楂苗定植前用10ppm萘乙酸浸根12小时,能提高其栽植成活率10～15％,山楂苗发根多,枝叶生长旺盛,叶片光合强度提高,翌年生长强健,抗旱力强。其提高植株萌芽率和促进枝叶生长的效应,均优于栽植后覆盖无色地膜。此项措施简便,成本低廉,已在生产上推广1000余亩。
Experiments carried out from 1985 to 1987 showed that the rooting of hawthorn seedlings with 10ppm naphthalene acetic acid for 12 hours before planting could increase the survival rate of the plants by 10-15%. The hawthorn seedlings had more hair roots, more foliage and leaves and photosynthetic intensity. The following year Strong growth, strong drought. The effect of increasing the rate of plant germination and promoting the growth of branches and leaves are better than that of the colorless film after planting. This measure is simple, low cost, has been promoted in the production of more than 1,000 acres.
