| 摘 要： | 为了解决干旱牧区天然牧场的雨水利用效率低的问题，通过对天然牧场进行全方位深松来增加雨水的利用效率。结果表明，深松后牧场的土壤密度平均下降0.14 g/cm3,牧场牧草的株高和产量增长量都比对照组有明显增加，平均增长率分别比对照组高42.98％和215.6％；水利用效率也相应提高，株高和产量的水利用效率增长幅度分别为13... |

| Abstract: | In order to solve the problem about the inefficiency of rainwater utilization in the pasturing area of north China,a field experiment was conducted for omnidirectional subsoiling in the natural pasture to increase the rain water use efficiency.The results indicated that the bulk density of soil had decreased after subsoil treatment,and the average decrease was 0.14 g/cm3.Compared with no-subsoil treatment,the increment of height and yield of grazing was distinct,the average height and yield of grazing was improved 42.98% and 215.6%,respectively.The rainwater use efficiency was increased too,the average height and yield of WUE was improved 130.3% and 210.1%,respectively.Not only the height of grazing,but also the growth density of grazing was increased. |
| Keywords: | natural pasture grazing subsoil water use efficiency |
