| 摘 要： | 为改善草地植物生存条件，对退化草地进行了改良试验研究，结果表明，３种改良方法都能改善草地生境，增中土壤速效养分。以施肥效果最佳，增加了牧草在草群中比重。禾本科、豆科和莎草科牧草分别比对照区增加９．０２－１０．１７％、１８．４０－２７．７６％和－６．７５％－１．８７％； 柯食牧草增加１倍；围栏封育草地效果次之，禾本科和豆科牧草在草群中所占比重分别比对照区增加２６．８１－３９．８５％和２０．７４－３７

| Abstract: | An experiment was conducted for degenrated grassland in
order to improve living condition of grassland plant. The result revealed that the quick acting
fertilizer of soil was increased by three grassland improvement methods. Among the methods
used, The fertilizer applying appeared to be the best, which increased the proportion of fine
herbage in the grass sward. Grasses, legumes and nutgrasses increased
9.02%10.17%,18.40%27.76% and-6.57%1.87% respectively compared with ck; plantable
herbages increased by 100%. The second was the pasture fencing, the proportion of the
grasses and legumes possessing in the grass sward increased 26.81%39.85% and
20.74%37.85%respectively than ck, nutgrasses decreased 11.85%19.23% than ck; the plantable
herbages increased by 100%. The third was turf cutting, the proportion of the grasses and
legumes increased 18.17%23.86% and 19.85%48.10% than ck; nutgrasses decreased
4.70%8.92% than ck; the plantable herbages increased 34.889.7% than ck. Thus the fertilizer
applying improvement and the pasture fencing were the good ways of grassland improvement. |
