啤酒大麦肥料运筹及精确施肥技术探讨

Discussion on Fertilizer Application and Precise Fertilization Techniques in Cultivation of Malting barley

分析了不同肥料运筹方式对大麦产量和养分肥料效应的影响，探讨了在高产栽培条件下的施肥指标，100kg籽粒需N2.350-2.883kg,无氮基础产量100kg籽粒需N1.896kg，氮肥利用率25.3%-50.3%，氮肥基肥，蘖肥和穗肥的最佳比例40%，30%和30%，应用修正后的stanford公式实现啤酒大麦精确定量施肥。

In this paper, it studied the effectiveness of different fertilizer application patterns on the yield, nutrient absorption and fer- tilizer effects. It also investigated the fertilizatinn index under high yield cultivation conditions. For example, 100 kg of grain need N of 2. 350 -2. 883 kg. Under nitrngen - free conditions, 100 kg of grain need N of I. 896 kg. Utilization rate of nitrogen is 25.3% -50. 3% while the best ratio of basic nitrogen fertilizer, tillering fertilizer and earing fertilizer is 40% , 30% and 30%. It also studied on applying the revised Stanlbrd formula tn achieve precise fertilization for malting barley.
