摘要
依据鄂尔多斯高原沙地草场牧草生长规律和白绒山羊的生物学特性,结合该地区家畜补饲、人工草地建立和沙地草场改良等草地畜牧业综合配套技术的研究,通过计算机模拟实验,确定了达拉特旗试验区绒山羊系统的优化生产模式。优化模式实施后,系统的年第一性生产力可达167.61gDM/m2,系统的全年载畜量为304.07个绵羊单位;系统的年第二性生产力水平按单位面积畜产品数量来计,绒、肉产量分别为0.543kg/hm2和6.351kg/hm2;系统年毛利为28865.85元。
In view of the biological
properties of herbage and goat in the sandy grassland of Ordos Plateau and the result of
simulant calculation. An optimal production model in Dalate Experimental Area was posed,
which was combined with the establishment of artificial pastures, the improvement of natural
grassland and supplemental feeding system of livestock. If being implemented, the model
could make the primary productivity at 167.61g DM/m 2, the second productivity at 0.543kg
Mohair/hm 2 and 6.351kg Mutton/hm 2 and the gross profit at 28865.85$ per year in Dalate
Experimental Area.
