苏打盐碱土改良及生态环境修复效果评价

针对黑龙江省西部松嫩平原草原盐碱化日趋严重、草原综合生产能力逐年下降等亟待解决的问题，就利用振动深松技术与生化土壤改良剂有机集成，对苏打盐碱土改良进行了研究。通过小区试验结果分析和大面积中试验证表明，集成技术的运用使苏打盐碱土的物理化学指标趋于良性化，牧草生长的土壤环境得到改善，牧草增产效果十分明显，提高了治理和综合开发盐碱化草原的水平：采用基于RAGA的PPC模型将该集成技术与对照区、围栏封育、浅翻轻耙等方法进行比较分析，进一步证明了集成技术治理盐碱化草原的有效性。

Improvement of Soda Alkali-saline Soil and Effect Evaluation of Ecological Environment Restoration

Grassland saline-alkalized of Songnen Plain was aggravating in the west of Heilongjiang Province,and general throughput of grassland was descending year after year.Aiming at a series of problems above that should be urgently solved,it is studied using deeply vibrating-loosening technology and improvement preparation of biological chemistry,and evaluating application effect of integrative technology on improvement of soda alkali-saline soil.The result analysis of small plot experiment and large-scale plantin...
