枫香人工育苗技术研究

采用随机区组设计了枫香不同年龄母树种子品质、不同播种时间(春播、冬播)和不同播种方式(条播、撒播)试验,进行枫香不同育苗方式对比研究。结果表明:不同年龄枫香母树种子产量和种子品质存在显著差异,20年生枫香母树种子千粒重、出籽率及发芽率分别均高于40年生枫香母树种子,因此枫香育苗宜选择20~30年生健壮无病虫害的母树采种。不同播种时间育苗的苗木生长和苗木质量无明显差异,春播苗木生长及苗木质量略优于冬播苗木。枫香条播与撒播育苗苗木生长和苗木质量无明显差异,但条播节省种子。因此枫香育苗宜采用条播,1年生幼苗发育可分为出苗期、幼苗期、速生期、苗木硬化期4个时期。

Study of Artificial Seedling Technology of Liquidambar formosana

The seed quality of different maternal tree, sowing time and sowing method of Liquidambar formosana were investigated in randomized blocks design. The results showed that there were significantly differences between the seed yield and quality of different age tree of L. formosana. The thousand grain weight,seed-extracting percentage and germination percentage from the twenty-year-old maternal trees were higher than those from the forty-year-old tree. Therefore, it was better to choose 20 to 30 year-old maternal trees without pest disease to pick the seed. However, there were no significantly differences between the seedling growth and seedling quality in different sowing times and with different seed methods, sowing in strip could save more seeds than broadcasting. Annual seeding growth of L. formosana could be divided into four stages, i. e. emergence stage, seedling stage, fast-growing stage, seedling hardening stage.
