本文报道了焦端狗尾草,刚裂片马唐、象草、坚尼草和俯仰臂形草3年内刈期间割为2,4,6,8周的干物质产量及营养价值。第一年各草的干物质产量无明显差异,以后两年稍有差别。第二、第三年的干物质产量约为第一年的一半。试验结果,第一年,牧草刈期间隔6周可获干物质产量25～42t/ha,以后各年较理想的为11～19t/ha。虽然在品质上,牧草之间存在明显差异,但较之刈期的
This article reports the dry matter yield and nutritional value of pythium, Stirrup, Crabgrass, Keni grass and Aegiceras corniculatus cut during 2,4,6,8 weeks during the three-year mowing period. In the first year there was no significant difference in the dry matter yield of the grass, with a slight difference in the next two years. The dry matter production in the second and third years is about half that of the first year. The results showed that in the first year, the yield of dry matter was 25 ~ 42t / ha after 6 weeks of forage harvest, and the average annual yield was 11 ~ 19t / ha in later years. Although there are significant differences in pasture quality, but compared to the mowing period
