摘要: 研究了水分胁迫下施用科瀚98 保水剂对湿地松Pinus elliottii 苗木的茎水势和生长的影响, 以及科瀚98 、黑金子和Stockosorb 400k 等3 种保水剂对火炬松Pinus taeda 苗生长的影响。结果表明, 施用科瀚98 保水剂可以明显提高湿地松苗的茎水势, 降低水分胁迫对松苗造成的危害。在整个胁迫过程中, 保水剂处理的苗木茎水势比对照高0.27 ～ 0.87 MPa , 而且胁迫越重, 两者之间的差异越显著。经过保水剂处理后, 湿地松苗的高生长和地径生长有明显的增加, 根部、地上部的干物质积累以及根冠比都不同程度地高于对照, 而且保水剂处理的松苗长势好, 不易萎蔫。在田间用科瀚98 、黑金子和Stockosorb 400k 等3 种保水剂处理火炬松苗近3 个月后, 苗木株高、地径和茎、叶相对含水量总体上比对照略高, 但由于受实验环境的影响, 3 种保水剂的施用效果都没有得到有效的发挥, 与对照间的差异不显著。图1 表3 参11

Abstract: The effect of Kehan 98 hydrogel on the stem water potential and growth of Pinus elliottii under water stressed and the effects of Kehan 98 hydrogel , Black Gold hydrogel and Stockosorb 400k hydrogel on the growth of Pinus taeda were studied .The results showed that Kehan 98 hydrogel could significantly reduce the water stress by increasing stem water potential of Pinus elliottii .Under the stress , the stem water potential of the pine seedlings treated with the hydrogel was 0.27 -0.87 MPa higher than the control group .Higher the stress was , more significantly the difference between the two groups was .The height and stem growth of Pinus elliottii were improved after it was treated with the hydrogel .The dry matter contents of the roots and above-ground parts , root-top ratio of Pinus elliottii were all higher than the control group .Pinus elliottii seedlings treated with hydrogel grew very well. The height , diameter at ground height , water contents of stems and leaves of Pinus taeda were a bit higher than the control group after them had been treated with Kehan 98 hydrogel , Black Gold hydrogel and Stockosorb 400k hydrogel for nearly three months .However , the effects of the three hydrogel were not fully played and there was no significant difference between the two groups because of the limited experimental environment .[ Ch , 1 fig .3 tab . 11 ref .]
