摘  要:
内蒙古河套灌区具有较强的速生丰产林发展潜力。竹柳的引进和栽培成为河套灌区林业产业经济发展的重要方向之一。对红皮竹柳和绿皮竹柳在河套灌区的抗旱、耐盐碱性进行了试验分析。结果表明:1)盐碱度是限制竹柳推广的主要限制因子,绿皮竹柳的耐盐阈值1.92%及红皮竹柳0.53%,p H值9.34;2)绿皮竹柳的耐旱性要高于红皮竹柳;3)重盐碱地区应栽植绿皮竹柳,轻盐重碱区可以考虑种植红皮竹柳;4)河套地区栽植竹柳时,推荐采用绿皮竹柳。

摘  要:
Hetao irrigation zone in Inner Mongolia possesses enormous potential for improving fast-growing and high-yield plantation,thereby introducing Salix( ‘Zhuliu') is a new trend for forestry industry development in Hetao irrigation zone. An experiment for investigating drought resistance,salt resistance,and alkali resistance of Salix( ‘Zhuliu') introduction was conducted in Hetao irrigation zone. The results suggested that 1) Salinity-alkalinity is primary factor limiting Salix( ‘Zhuliu') planting. Salt tolerance threshold for green Salix( ‘Zhuliu') and red Salix( ‘Zhuliu') is 1. 92% and 0. 53%,respectively. Alkali resistance threshold for red Salix( ‘Zhuliu') is p H 9. 34. 2) The drought resistance of green Salix is higher than that of red Salix. 3) Green Salix( ‘Zhuliu') should be planted in heavy saline-alkali zone,and red Salix( ‘Zhuliu') planted in lighter saline-alkali zone. These results indicated that green Salix( ‘Zhuliu') is the first choice,when Salix( ‘Zhuliu') planted in Hetao irrigation zone.
