大庆地区几种草坪草耐盐性研究

Studies on Salt Tolerance of Several Kinds of Turfgrasses in Daqing

对大庆地区欲引种的4个草坪草品种进行了耐盐性的比较研究。用质量比为3/2的NaCl/Na2SO4复盐溶液,胁迫处理幼苗期高羊茅、翦股颖和草地早熟禾。通过对盐胁迫下草坪草叶片可溶性糖含量、细胞膜透性、叶绿素含量的变化。结果表明:4个草坪草品种耐盐碱性依次为:强劲高羊茅>帕特匍匐翦股颖>纳苏草地早熟禾>兰神草地早熟禾。

Took 4 kinds of torfgrass to did salt tolerance experiment that suit for Daqing area. Stressed with mass ratio was 3/2 that of Nad/Na2SO4 salt solution to Tall fescue,Eralus Creeping bent grass and Natrium Soriet. through testing the soluble sugar content, drift away the praline content, the chlorophyll content, the cell membrane penetrability change compares,of four kind of lawns grass anti- salt alkaloid ability, the sesuts showed： strong high Tall Fescue ~ crawls Creeping Bent grass 〉 Natrium Soviet 〉Blue god. Therefore obtains strong high Tall Fescue suited the Daqingarea, for bears salt alkaloid strong, the growth exuberant, the color thick was green and the comprehensive character fine variety.
