一、播前准备1．造地。根据大麦早熟、耐肥不耐湿的特性，要选择排水良好的地块播种啤酒大麦。从需肥特性看，啤酒大麦适宜的前茬为甜菜，可降低蛋白质含量。在肥沃的地块不宜选豆茬做前茬，以防提高籽粒蛋白质含量。所选地块要有稳定的灌水条件，最好选中性粘壤土。砂质土种大 First, prepare before sowing Land preparation. According to the characteristics of barley precocious, resistant to moisture, we should choose the well-drained plots to sow beer barley. From the characteristics of fertilizer needs, beer barley suitable for the first crop of sugar beet, can reduce the protein content. In the fertile plots should not be selected stubble stubble, in order to prevent the increase of grain protein content. Selected plots have a stable irrigation conditions, the best selection of neutral clay loam. Sandy soil species
