黄土旱塬粮食高产记录及其启示

研究了黄土旱塬区历史的与当今的粮食高产记录 ,结果表明 ,目前黄土旱塬各地出现的一料作物单产 15t/hm2 ,在国内其它地区也不多见。据此明确指出 ,黄土旱塬区粮食生产有巨大潜力 ,深入开展粮食高产研究必将推动粮食“高产、高质、高效”的全面发展 ,还将促进农业科学研究取得长足进步以至突破性发展 ,创建粮食高产还可成为治理水土流失与改善生态环境的突破口

The high yield grain records in the dry land of Northern Plateau Region in history and at the present time were studied. Results show that the "1 ton grain yield per mu" obtained in the dry land of western region was rare in the other domestic region. It is concluded that there is a great potential in grain yield in the Plateau Region. Further carry out the study on high yield grain will propel the all round development of high yield, high quality and high efficiency in grain production, promote scientifi...
