补充资料：人工草地
| 人工草地 tame grassland 采用农业技术措施培育而成的草地。目的是获得高产优质的牧草，以补充天然草地之不足，满足家畜的饲料需要 。用来割刈牧草作青饲、青贮或干草的称人工草场。用来直接放牧的称人工牧场。在不破坏或少破坏土层和天然植被的情况下，通过补种、补播和其他措施培育而成的草地称改良草场。人工草地比天然草地生产力高，对减少家畜因冬春饲料不足而掉膘或死亡，增加畜产品产量和质量，提高土地利用率等具有重要意义。因此人工草地面积的多少，通常是衡量一个地区或国家畜牧业发达程度的标志。欧美各国人工草地面积约为耕地的50％以上， 1990年中国人工草地面积约为1.3亿亩，约为耕地面积的7.5％，占天然草原的2.5％。中国人工草地中推广的草种除紫花苜蓿外，北方地区还有沙打旺、老芒麦、披碱草、无芒雀麦等；南方多用红三叶草、白三叶草、多年生黑麦草和鸭茅等。人工草地按其用途和利用时间长短可分为轮作中的短期草地、永久放牧地和永久割草地。 |
