国营黄羊滩农场地处贺兰山东麓沙质淡灰钙土地区,开垦时间短,土壤熟化度低,理化性质差,有机质含量少,质地偏沙,漏水漏肥,因而一次施肥,尤其是氮素化肥,不仅肥料利用率降低,而且造成作物中后期脱肥早衰。近年来,我场根据淡灰钙土地区啤酒大麦生长发育规律及需肥特点,经过多年反复试验及大面积生产示范,总结出近万亩啤 The state-run Huangyangtan farm is located in the sandy litter of calcareous soil in the eastern foot of Helan Mountain, with short reclamation time, low soil ripening degree, poor physical and chemical properties, low organic matter content, sandy texture and leakage and leakage of fertilizer. Nitrogen fertilizers, not only reduce the utilization of fertilizers, but also lead to premature delamination in the late crop. In recent years, based on the law of growth and development of beer barley in light gray soil area and the need of fertilizer characteristics, after many years of repeated experiments and large-scale production demonstration,
