| 摘 要： | 对球茎、种子苗两种不同类型白及苗种植后的物候进行了定株观测,并调查了两种类型种苗在不同种植密度下的产量。结果表明:两种繁殖类型的白及植株出芽、展叶期基本一致,球茎和种子苗植株出芽期、展叶期、开花期、果期持续时间差异不大,而黄枯期差异较大。不同种苗类型和不同种植密度对白及产量有显著影响。采用球茎种植的白及产量显著高于种子苗种植的产量,本实验中,以种植株行距为15 cm×15 cm产量最高,在水肥条件较好地段,可适当密植提高产量。

| Abstract: | The phenology of bulb seedlings and seed seedlings of Bletilla striata was observed and the yield of the two types of seedlings under different planting densities were investigated.The results showed that the budding and leaf spreading stages of the two propagation types of Bletilla striata were basically the same.There was no significant differences in the duration time of budding,leaf spreading,flowering and fruit stages between two different seedling types,but there was a big difference at the yellow-withered stage.Different seedling types and planting densities had significant effects on the yield of Bletilla striata.The yield of Bletilla striata planted with bulbs was significantly higher than that of seed seedlings.In this experiment,the highest yield was obtained when the row spacing of seed plants was 15 cm×15 cm.Under better water and fertilizer conditions,the yield could be increased by appropriate close planting. |
