摘　　要：沼泽草场改良采用翻粑措施遇到的首先问题是地下水位。本文在三种地下水埋深水平上进行翻耙试验,以单因子对比分析研究沼泽草场适宜地下水埋深条件下的翻耙技术。试验结果表明,沼泽草场在地下水埋深为40～60厘米时每隔三年翻一次可取得满意的改良效果;但在应用上,技术措施配合得当翻耙才能成功。To use ploughing to improve the swampy pastures,one of the critical factors is the water table. This paper describes the ploughing and raking test under three different ground water levels so as to make a comparion with each other between single factors,and to conduct an investigation into ploughing technique under advantageous ground water level of swampy pastures. Tests show that when the ground water level is 40～60 cm,ploughing and raking in swampy pastures,at three—year intervals, may achieve satisfactory results. Although these techniques are successful in doing this, yet they should be carried out systematically in practise.
