穴盘规格对5种苔草属植物育苗的影响

穴盘育苗是苔草繁育的重要技术环节。为加快苔草的繁育速度,采用不同规格穴盘播种以研究青绿苔草(Carex breviculmis)、涝峪苔草(C.giraldiana)、披针苔草(C.lanceolata)、矮丛苔草(C.humilis var.nana)、脚苔草(C.pediformis)的适宜播种穴盘孔数对5种苔草出苗和幼苗生长的影响。通过对各种苔草的开始发芽时间、持续发芽时间、发芽率和幼苗的株高、叶数、单株鲜重等生长指标的分析,结果表明,6月温室穴盘播种育苗,青绿苔草、涝峪苔草穴盘育苗128孔或105孔穴盘较为适宜;披针苔草穴盘育苗宜采用105孔穴盘;矮丛苔草、脚苔草穴盘育苗较适宜选择288孔穴盘。

Effects of plug size on grow seedlings of five Carex species

This study was carried out to select appropriate plastic tray for C.breviculmis, C. giraldiana, C. lanceolata, C. humilis var. nana and C. pediformi seedlings growing. Six important indexes including germination initial time, germination duration time, germination rate, plant height, leaf number and fresh weight of five Carex spices were compared and analyzed. The result was as follows: the plastic trays of 128 cells and 105 cells were more appropriate for C. breviculmis, C. giraldiana; the trays of 105 cells were appropriate for C. lanceolata; the trays of 288 cells were appropriate for C. humilis var. nana and C. pediformis.
