近年来,我们在双季稻区试验推广种植二棱大麦,取得了明显的增产效果和经济效益,1986—1988年,全市种植大麦5.58万亩,平均亩产142公斤,珠梅乡东边村连片种植685亩,平均亩产207公斤,其中有178亩,平均亩产达到263公斤。通过几年的实践,我们有如下体会。一、选择良种种植良种对提高产量具有十分重要的作用。通过多年品种观察和区试,76—25、81—86、盐辐矮早三是 In recent years, we have popularized the cultivation of two-rowed barley in the double-cropping rice area and achieved remarkable yield-increasing effects and economic benefits. From 1986 to 1988, the city planted 55,800 hectares of barley with an average yield of 142 kg per mu. 685 acres of film planting, the average yield of 207 kilograms, of which 178 acres, an average of 263 kilograms per mu. After several years of practice, we have the following experience. First, the choice of elite varieties of seeds to improve production has a very important role. Through years of variety observation and regional test, 76-25,81-86, salt dwarf is as early as the third
