黑龙江省西部盐碱地适生树种选择及造林技术研究

Selection of Adaptive Tree Species in Salt-Alkaline Area in Western of Heilongjiang Province and its Afforestation Techniques

探讨了全面整地、筑台造林对盐碱土理化性质的改善作用，评价了10个参试造林树种的耐盐碱能力，确定了樟子松容器苗在黑龙江省西部低湿盐碱地的适生、忍耐和致死pH值和含盐量阖值分别为〈8．675、8．679—8．775、〉8．807和〈0．1008％、0．1051％-0．1292％、〉0．1309％。

Improving effect of whole soil preparation and afforestation on hathpace on saline soils was discussed. Saline-alkali tolerance of 10 experimental species were evaluated. Suitable, tolerance,lethal pH value and salt content threshold of container seedlings of Pinus sylvestris var. mongolica in western area of Heilongjiang province is respectively 〈 8. 675,8. 679-8. 775, 〉8.807 and 〈0. 100 8% ,0. 105 1%-0. 129 2%, 〉0. 130 9%.
