它是由象草和美洲狼尾草杂交育成的禾本科牧草,在热带、亚热带地区的许多国家已广泛种植。1987年广东省农科院畜牧所引种试验研究,结果表明:在不同地力条件下,其亩产草量为4819.8～11980.7公斤,比象草亩4602.1～9011.1公斤高4.7～33.0％;粗蛋白含量在高肥水平下,皇草为18.06％比象草(16.52％)高1.54个百分点;在低肥水平下,皇草为17.11％比象草(13.80％)高3.31个百分点。植株各茎段的含糖量 It is a gramineous pasture that has been cross-bred from grass weed and African bush weed and has been widely planted in many countries in the tropics and subtropics. In 1987, Guangdong Provincial Academy of Agricultural Sciences introduction of livestock husbandry pilot study showed that: under different land conditions, the yield per mu 4819.8 ~ 11980.7 kg, grass than the grass 4602.1 ~ 9011.1 kg 4.7 ~ 33.0% higher; crude protein content Under the high fat level, the royal jungle is 18.06% higher than the grass (16.52%) 1.54 percentage points; at low fat levels, royal jungle is 17.11% higher than the grass (13.80%) 3.31 percentage points.
