高羊茅耐盐性研究

Study on Salt Tolerance of Festuca arundinacea

以高羊茅为试材,开展不同盐浓度对高羊茅耐盐性的影响试验。结果表明:高羊茅的耐盐性不是很强,在0.21%以下的盐浓度范围内可以正常生长,在0.21%～0.43%的盐浓度之间可以存活。我国大部分盐碱土都在1%盐浓度以下,其中有相当一部分的含盐量在0.5%以下,所以对于高羊茅还具有一定的适种范围。

Festuca arundinacea as test material, effect of different salt concentration on salt tolerance were conducted. The results showed that： the salt tolerance of Festuca mundinacea was not very strong. It can grow normaUy in the range of salt concentration below 0.21%, and can be survive in 0.21% ,- 0.43% salt. Most of the saline alkali soil in our country is below 1% salt concentration, of which a considerable part of the salt content is below 0.5%, so there are certain suitable range for Festuca arundinacea growing.
