摘要
2000~2002年在内蒙古东部区四盟市开展了主要作物降水利用率与生产潜力的研究。经过3年的调查研究,建立了大豆、玉米等六大主栽作物的降水生产潜力模型,分析讨论了各地区不同作物降水资源的利用现状。
From 2000 to 2002, we applied the project<to establish representative area of dry agriculture of nation>o practice in the four regions in the east of Mongolia, while we studied the subject of availability and productive capacity of precipitation on the main crop. Via investigation on three years , we estabished the model of productive capacity of precipitation about six main cultivating crops such as bean, zea mays and so on, and analyzed and reached the conclusion about the present situation of availability of precipitation resource on the different crops and in the different areas.
