阜城县属冀中低平原麦区,历年种麦30万亩左右,土地瘠薄,气候干旱,产量偏低。近年来由于强化科技投入,普及高新技术,使小麦产量得以大幅度增长。1995年平均亩产达351公斤,比1994年增加42公斤,增产13.6％。具体做法是: 一、发挥个体、群体两个优势,是高产再高产的重要途径。实践证明,亩产300公斤以上的麦田,在亩穗数40—45万的情况下,穗粒数和千粒重与产量呈极显著正相关。根据冀中低平原区冬小麦 Fucheng County is a lowland plain in Hebei Jizhong wheat, calendar year, about 300000 acres of wheat, barren land, arid climate, the yield is low. In recent years, as a result of intensified investment in science and technology and the popularization of high technology, the output of wheat has greatly increased. In 1995, the average mu yield reached 351 kilograms, an increase of 42 kilograms over 1994, and an increase of 13.6%. The specific approach is: First, to play an individual and group two advantages, is an important way of high yield and then high yield. Practice has proved that, per mu yield of more than 300 kg of wheat fields, in the case of 400000-4000000 acres of grain, grain number and 1000-grain weight and yield were extremely significant positive correlation. According to the Jizhong low plain winter wheat
