垄作栽培对啤酒大麦产量和品质的影响

探讨在等量灌水条件下垄作栽培对啤酒大麦产量和品质的影响。结果表明：（1）垄作栽培生育期长于传统平作栽培，单株穗数低于传统平作栽培，经济系数高于传统平作栽培，株高、穗粒数、产量影响趋势不一致，品种之间存在差异。（2）原麦品质：垄作栽培与传统平作栽培籽粒千粒重之间差异不显著，蛋白质含量之间差异显著，粒筛选率之间差异极显著水平，千粒重、蛋白质含量、筛选率均降低。（3）麦芽品质：垄作栽培麦芽蛋白质含量均较传统平作栽培降低，麦芽细粉浸出物、β-葡聚糖、a-氨基氮、a-淀粉酶、糖化力、可溶性氮之间差异不显著，库值含量之间差异达显著水平，但影响趋势不一致，品种之间存在差异。

Effect of Ridge culture on Barley Yield and Quality

This paper discussed the effects of ridge culture on barley yield and quality under the condition of equal amounts of irrigation. The results showed that： （1） the ridge culture growth period was longer, ear number per was lower and economic coefficient was higher than the traditional culture cultivation, there were differences between varieties plant height, spike grain number and yield. （2）Quality of the barley： compared with traditional culture cultivation, ridge culture＇ s thousand seed weight, protein content, screening rate were reduced. There were no significant differences between ridge culture and traditional culture cultivation in the grain per spike, but protein content was significant and screening rate was extremely significant differences. （3） Malt quality： malt protein content was lower than traditional culture cultivation. There were no significant differences between malt powder extract, or-amino nitrogen, β-glucanase, a-amylase, diastatic power and soluble nitrogen. Malt Kolbach index was significant differences between varieties, but the impact trend,
