| 摘 要： | 吉林省西部草原大面积退化严重破坏了吉林省中西部生态环境系统的平衡,已成为制约吉林西部草原可持续发展的主要因素。针对吉林西部严重退化草地的土壤硬度大、结构致密等特点,研究采用浅耕翻和深松两种不同翻耕方式对表层土壤环境进行修复,并选用5种适宜本地区的优良牧草进行田间对比试验。结果表明在吉林西部施行深松和浅耕翻可以明显改善土壤环境,相比之下深松效果比浅耕翻好;所选5种草种在吉林西部生长旺盛。

| Abstract: | The pasture of western Jilin had degenerated for a large areas, which have heavily damaged the balance of ecology and environment, and have become the main restrictive factor for the sustainable development of the pasture. The surface soil of the degenerated pasture have consolidated, exhibited a heavy rigidity, compact structure, pores destroyed. The objective of this study was to meliorate surface soil of degenerated pasture by shallow and deep plowing, respectively, by five fine quantity pasturage. The result shows that plowing can meliorate soil environment very well, and deep plowing did better in the pasture of the western Jilin. Further studies were going on. |
