| 摘 要： | 在牧草生长季节(5~9月)对小哨牧场放牧演替形成的5个草地型草地的牧草进行生长速率、牧草产量及养分的逐月观测,生长速率测定显示,白三叶+东非狼尾草和东非狼尾草+非洲狗尾草两个草地型草地均出现两个生长峰值,分别在6月和9月,其余3个草地型草地只有一个生长高峰。干物质产量和牧草养分测定结果表明,白三叶+东非狼尾草和白三叶+非洲狗尾草+画眉草两种草地型草地表现最好,可以在气候环境条件类似的地区推广种植利用;白三叶+画眉草和白三叶+非洲狗尾草两种草地型草地表现优良,可以在草地改良中,根据当地实际情况选择性地加以种植;东非狼尾草+非洲狗尾草型草地表现较差,不提倡种植。

| Abstract: | In the growth season of pasture(May~September),through dynamic study on the pasture growth rate and nutrient of five grassland style,the monitoring result on pasture growth rate showed: White clorer+kikuyu grass style and kikuyu grass+setaria grass style had two growth peak in June and September,another three style had only one growth peak. The measure on pasture DM yields and nutrient indicated:white clover+kikuyu grass style and white clover+setaria grass+love grass style were the best; white clover+love grass style and white clover+setaria grass style were good;above style could be planted or selectively planted for animal production;kikuyu grass+setaria grass style was low grade,not advo- cated to plant. |
