摘　　要：为评价保水剂在桉树生长中的作用,研究了2种保水剂用量和4种水分供应条件下,巨尾桉苗木的生长量、净光合速率、蒸腾速率和叶绿素含量的变化情况。结果表明,随着田间持水量增加,除了叶绿素含量差别不大,苗木的高增长量、地径增长量、净光合速率均显著上升;施用保水剂的效果与田间持水量60%和80%处理的作用基本一致,保水剂在桉树人工林中的使用是可行的。In order to evaluate the effects of absorbent polymer on the growth of eucalyptus, the increments, net photosynthetic rate, transpiration rate and chlorophyll content of Eucalyptus grandis × E. urophylla, which grew in two absorbent polymers and four water-supply conditions, were studied. The result showed that the increments of height and ground diameter, net photosynthetic rates were increased obviously as the increase of the field moisture capacity. However, there were no significant differences in chlorophyll contents. The application effect of absorbent polymer was similar to those treatments of 60 % and 80 % of field moisture capacity. The conclusion proved that the application of absorbent polymer in Eucalyptus plantation was practicable.
