摘要
从黄土高原地区粮食发展历史经济和十多年来科技攻关实践及生产潜力的调查和试验证明 ,该区域在资源潜力和技术潜力上有能力达到粮食自给。据中科院水土保持研究所在长武站试验 ,1 993年在正常降水的情况下 ,小麦产量 4 94 4 kg/hm2 ,玉米产量 94 78.5kg/hm2 ,两料产量达 1 442 2 .5kg/hm2 (961 .5kg/亩 ) ,创该区历史最高记录。通过多方面的努力 ,黄土高原粮食生产连续上了几个台阶 ,其中选育高产、优质、多抗粮食作物品种 ,应用高产、高质、高效配套技术在粮食生产中的作用与地位更为明显 ,应引起决策者和生产者的高度重视 ,并加以总结和推广 ,根据实际情况进行系统研究 ,以满足 2 1世纪人民对粮食之需。
It proved Loess Plateau had abitity to reach self-supporting in grain that its developing history in grain, the key technological practice for more than ten years, and the investigation and expriment of productive potentialities According to my expriment in Changwu station, on the condition of normal precipitaton in 1993, wheat yields was 4 944 kg/hm 2, corn yields 9748 5 kg/hm 2, total output up to 14 422 5 kg/hm 2,this was an all-time high, through many-yield efforts, grain production of Loess Plateau Continuously went up a few steps Among, breeding high-yield, high-quality,multiresisiting varieties and applying high-yield, high-quality,high-effective technology were more obvious, should be paid much attention by decisioner and producer, and were summarized and popularized, were systematically studied according to the actual condition to meet the people's demands for grain in 21 century
