| 摘 要： | 在3种土壤含水率条件下,研究了I-69杨插条苗的苗高、叶面积等生长进程和生物量。不同供水条件下苗木的生长进程相似,低供水处理封顶期提早10～15d.生物量测定表明,I-69杨十分喜水,高供水处理(土壤含水率保持在田间持水量的96％)的生物量为低供水处理(土壤含水率为田间持水量的55％)的2.74倍。

| Abstract: | The growth and biomass of the rooted cuttings of I -69 poplar (Populus deltoides GV. 'Lux' I-69/55) were researched in three different soil water contents (96%, 75% and55% of field capacity) . The plants in all treatments were similar in growth course, but the budset date of the plants grown in water content was 10-15d earlier than others. The biom-ass measurements demonstrated that: I -69 poplar was a high water-demanding species. The biomass at watering level of 96% field capacity was 2.74 times as much as at watering level of 55% field capacity. |
