　　通过采用塑料袋、纸杯和草炭杯3种容器进行樟子松育苗试验，结果表明，3种容器持水力相差较大，草炭杯持水力最小；塑料容器较纸杯提早2d、比草炭杯提早4d达出苗高峰，出苗时间缩短2～6d；塑料袋内根系盘旋生长及窝根现象非常严重，纸杯旋生现象较塑料袋为轻，草炭杯的侧根较短较少，但须根特别发达。不同容器地上部分生长影响差异极显著，草炭杯由于保温保水能力较差，生长缓慢，塑料袋和纸杯对地上部分生长较为有利。

Nursery trials of Pinus sylvestris var .mongolicawere conducted by using three kinds of containers (plastic bags ,paper cups & peat cups) .Result shows that :water holding capacity of the three kinds of containers are lar-ger ,water holding capacity of peat cups is the least ;seedlings sprouted two days and four days earlier by using plas-tic container cups than paper cups ,peat cup ,respectively and time of emergence are shorted by 2-6 d;phenomenon of spiral growth & twisted root in plastic bags is very serious ;phenomenon of spiral growth of root in paper cups are lighter than that in plastic cups ;lateral root in peat cups are shorter & less ,but its fibrous roots are well-developed . Grow th of different containers aboveground is significantly different ;capability of heat preservation & water conser-vation of peat cups is poor ,so the growth is slow ;plastic bags & paper cups are more favorable for growth of seed-lings aboveground .
