摘要
本试验旨在评价不同采收年龄的苏克普蒂罕草的产草量和能值。试验采用完全随机设计，3个处理，3个重复。三种处理分别为40 d (BP40)、60 d (BP60)、80 d (BP80)。观察的指标包括干物质产量、茎叶比、体外消化率和能值。结果表明，落叶年龄对苏克普蒂罕草的干物质产量、茎叶比、干物质消化率有极显著影响(P<0.05)，对苏克普蒂罕草的有机质消化率和能值有极显著影响(P<0.01)。苏克普提罕草(Bothriochloa pertusa)的干物质产量随着落叶年龄的增加而增加，但由于茎叶比高和采收时间的延长，其体外消化率和能量值降低。综上所述，百叶白花的最佳落叶时间为种植后40 ~ 60天。
Effect of Defoliation Age on The Production and Energy Value of Indian Bluegrass (Bothriochloa pertusa)
The purpose of this experiment was to evaluate the herbage production and energy value of Suket putihan grass (Bothriochloa pertusa) harvested at different ages. The experiment was carried out following a completely randomize design with 3 treatments and 3 replications. The treatments consisted of different defoliation ages of Suket putihan grass (Bothriochloa pertusa), i.e. respectively at 40 days (BP40), 60 days (BP60), 80 days (BP80). The observed variables included the dry matter (DM) production, stem leaf ratio, In vitro digestibillity and energy value. Result showed that the defoliaton age had a significant effect (P<0.05) on dry matter production, stem leaf ratio, dry matter digestibillity and had a very significant effect (P<0.01) on the organic matter digestibillity and energy value of Suket putihan grass (Bothriochloa pertusa). The DM production of Suket Putihan grass (Bothriochloa pertusa) increased with increasing defoliation age, while its In vitro digestibility and energy value decreased due to the high stem to leaf ratio and increased harvesting time. In conclusion, the best defoliation time for B. pertusa is between 40 and 60 days after planting.
