| 摘 要： | 农牧交错地带在我国农业生产中占有十分重要的地位,而水资源又是该地区农业发展瓶颈。以内蒙古伊金堆洛旗为例,对农牧交错地带种植业中自然降水资源的利用进行了分析,认为由于降水不合宜,地力不足,盲目开垦和水分利用率低,存在着粮豆单产严重依赖降水且产量不高的问题,并从作物,水,地力等方面提出了对策。

| Abstract: | The borders between farming and ranging regions are very important to our country in agricultural production;on the contrary,water resource is the bottleneck of development of these regions.This article analyzes water utilization in the crop production in the semi-arid areas.Because of the natural and man-made factors,there are questions that the crop production depends too much on the precipitation and the output is low.From the view of the utilization of precipitation,this paper analyzes the reasons to the questions.At last,the countermeasures are put forward according to these problems. |
