大丰是全国啤酒大麦重点生产市(县),常年种植面积40万亩左右,单位产量虽高于全省平均产量。但品质下降,千粒重低,发芽率不高,蛋白质含量偏高而不适应啤酒工业生产需要,造成啤酒生产原料依赖于进口“澳麦”、国内啤酒大麦滞销的被动局面。为此对啤酒大麦实施“五推五改”技术研究,主要目标是:在稳定提高啤酒大麦产量的前提下,提高“啤麦”质 Dafeng is the key manufacturing city (county) of national beer barley, and the perennial planting area is about 400,000 mu. Although the unit output is higher than the average output of the province. But the quality declines, the grain weight is low, the germination rate is not high, and the protein content is too high to meet the need of beer industrial production, resulting in the beer production raw material relying on the import of “Australian wheat” and the domestic beer maltose. To this end, the implementation of “Five-push-five-change” technology research on beer barley mainly aims to improve the quality of “beer malt” under the premise of steadily increasing the production of beer barley
