松嫩平原盐碱化草地改良治理的研究

松嫩平原草地目前出现大面积盐碱化和碱斑，严重影响畜牧业的发展，加速生态环境的恶化，对其进行改良和治理已是科研和生产亟待解决的问题，我们在出现大面积盐碱斑的草地上开展了自然封育，生物，化学，物理和工程等改良治理的研究，通过多年的实验，证明上述措施都有一定的效果，但以生物措施治盐碱效果为最好，为今后碱化草地的改良治理提供了理论依据和治理措施。

Studies on Improving Saline-alkaline Grassland in Songnen plain

Recently,large saline-alkaline areas have appeared in the Songnen Plain,seriously affecting animal husbandry and aggravating the ecological enviornment.Thus,it becomes essential to find ways to improve saline-alkaline grassland through scientific research and practice. We have been doing enperiments for many years and have developed a number of treatments including natural closure,biological,chemical,physical and engineering methods. The results proves that biological methods are the most effective ones.This study puts forward theories and measures for improving saline alkaline grassland.
