摘要
针对农牧交错区面临的主要生态问题、当前及退耕还草后面临的粮食问题,提出了该区退耕还草后提高粮食自给能力的基本对策:改造基本农田,强化农牧结合,建立农业"三元"结构体系,充分应用现代旱作农业技术,发掘退耕还草后剩余农田粮食生产潜力。
Aimed at the main environmental problems in the ecotone of agriculture and animal husbandry, transferring farmland to grassland is in the pride of place. Based on the problems of food guarantee after the transformation, this paper puts forward basic countermeasures for enhancing the ability of food supply in the ecotone of agriculture and animal husbandry. They are reconstructing fundamental farmland; strengthening the combination of agriculture and animal husbandry; establishing tribasic cropping structure; and applying modern dryfarming techniques so as to exploit the productive potential of arable land.\;
