农七师廿一团农场,自一九五一年生产以来,因土壤瘠薄、粘重,兼有盐碱,冬麦产量很低,一九六三年以前的十三年平均单产仅139斤。一九六四年,单产才上升到292斤。一九六五年22,500多亩冬麦普遍生长良好,单产达到了310斤,其中3,500多亩单产430斤,有170多亩一条田单产达到了484斤。 两年来冬麦产量不断提高的主要技术经验如下: Since the production of the farm in 1961, the farm has enjoyed a very low yield of winter wheat due to infertile soils, sticky weight and salinity. Since then, the average yield per unit of production in the thirteen years before 1963 was only 139 pounds . In 1964, the yield rose to 292 pounds. In 1965, more than 22,500 mu of winter wheat were generally well-to-grow with a yield of 310 pounds, of which 430 hectares were covered with 3,500 hectares and 484 hectares with 170 hectares. The main technical experience of increasing winter wheat production in the past two years is as follows:
