On Converting Methods of Natural Grasslands with Artifical Grass Covers in Banks

Abstract

1. This experiment was undertaken to determine the suitable methods and kinds of grass converting banks from natural grassland into artificial grass covers. 2. This experimental plots were as follows. A) Seeding in parts where cultivated as stripe along same heigh level. B) Seeding by broadcast method into many circle-ploughed parts. C) Seeding into little scratched hollows. D) Seeding by broadcast method on total area. 3. The results obtained were summerised as follows. i) In the above 4 methods A)-plots were the best, B)-, C)-and D)-plots showed somewhat similar achievements. ii) The difference between the methods was scarcely, but it between kinds of grass was obvious, that is, both the Orchard grass-Ladino clover and the Timothy-Red clover mixture was much better than Orchard grass, Ladino clover, Birds-foot trefoil and White clover alone by yields of green forage, weight ratio of grass per weed and cover degree. iii) The autumn ought to be selected for the optimum sowing time of grass.
