摘要
比较黎蒴扦插苗与实生苗苗期和造林后7个月及31个月的生长情况,发现黎蒴扦插苗多个性状优于实生苗;造林初期,实生苗生长较快,生长明显优于扦插苗,扦插苗蹲苗期较长,但后期扦插苗生长可以超过实生苗。从目前情况来看,黎蒴扦插苗造林值得推广。
Compare on five characters between the cutting stock and seedings of Castanopsisfissa, four char- acters of cutting seedlings are better than seedlings ; in early stage of afforstation, seedlings grow faster than cutting seedlings, but about one year later, cutting seedlings grow faster than seedlings. Judging from the present condi- tion, afforestation by cutting stage is feasible.
