土壤中如果盐碱质的含量过多时,能够破坏土壤结构,低湿地区造成渗水情况不良,干旱时呈现板结,排除或闭室土壤中植物生长所需的氧气,使植物根部细胞的生殖机能遭到破坏。所以在盐碱地区仅仅生长一些耐碱性的植物,如:茅草,车轱辘草,接骨草,碱草,三叶草,盐蓬等,很少有树木或其他农作物生长。而一般养路员工则对盐碱地区的公路绿化信心不大。其实根据科学度验的结果,证明在含有盐碱质的土壤中是可以生长树木的,只要我们耐心地选植抗盐碱性能强的树种,并设法改良土壤条件,盐碱地区公路是一定能够达成绿化的。兹将有关盐碱地区植树应注意的事项提供参考:
If the content of salinity and alkalinity is too much in the soil, the soil structure can be destroyed, water infiltration is poor in the low-humidity area, and the compaction occurs in the drought, and the oxygen required for plant growth in the closed-cell soil is excluded, so that the reproductive function of plant root cells is affected damage. Therefore, in saline-alkali areas, only some plants with alkali resistance are grown, such as thatch grass, car reels, croaker grass, soda grass, clover, saltpeter and so on. Few trees or other crops grow. The general road maintenance staff on the saline-alkali highway green confidence. Actually, according to the result of scientific inspection, it is proved that trees can grow in the soil containing saline-alkali soil. As long as we patiently choose tree species with strong anti-salinity properties and try to improve the soil conditions, the highway in the saline-alkali region will surely reach the goal Greenery I will provide information on matters requiring attention in tree planting in saline-alkali regions:
