黄土高原粮食生产潜势与高产技术研究

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，该区域在资源潜力的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。１９９３年在正常降水的情况下，小麦产量４９４４ｋｇ／ｈｍ＾２，玉米产量９４７８．５ｋｇ／ｈｍ＾２，两料产量达１４４２２．５ｋｇ／ｈｍ＾２（９６１．５ｋｇ／亩），创区历史最高记录。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

A STUDY ON THE POTENTIAL FOR GRAIN PRODUCTION AND HIGH-YIELD TECHNOLOGY IN LOESS PLATEAU

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
